How HVAC Systems efficiency can be improved through IoT?

How HVAC systems can be combined with IoT for better efficiency?

HVAC & IoT

Data is critical now and the same is true with HVAC Systems for HVAC efficiency. Questions mentioned below cannot be answered due to non-availability of data.

  •  ‘How does your HVAC equipment – your chiller or boiler plant, as examples – behave on a 60-degree day without humidity?’
  •  ‘How do they behave on an 80-degree day with high humidity?’

However, these questions can be answered with IoT technology. IoT solutions in tune with local weather data provide HVAC Companies answers in terms of their equipment today, as well as last week and last month. By implementing data into daily operations, you can improve efficiency, maintenance and overall preparedness for your building’s HVAC systems.

Savings in Operational Cost

IoT technology helps in improving energy efficiency in HVAC systems as it helps adjust more precisely to current and changing conditions, achieving 5-15% in energy savings for HVAC systems.

This is done by deploying sensors on the electrical infrastructure in the building to measure the real-time equipment-level consumption of the individual components in the HVAC system Hence, whether that’s a pump, an individual fan or a cooling tower, a software is used to deploy sensors to collect equipment-level data and combining it  with local weather data

Based on the amalgamation of data, HVAC Company can adjust HVAC equipment to better account for changes in the weather. In terms of geographical areas, it is definitely beneficial everywhere, but for places that have more seasonality and greater temperature swings, it can be more

Lesser HVAC Maintenance Cost

By analyzing the above practice, an HVAC Company can identify peak performance and underperformance of all HVAC equipments. For example, if tomorrow’s forecast is a 60-degree day with low humidity, an HVAC Company analyses  how the equipment should behave

Also, one more example, if an HVAC system is supposed to be drawing 200 kW of power but is for some reason drawing above or below that, with IoT it becomes easier to pinpoint what is wrong

Heightened efficiency in response to weather changes

Most IoT sensors pull multiple data points such as temperature, wind speed, humidity, cloud coverage, and precipitation.

The data for precipitation can prove particularly valuable to protect your building against flood damage. When local weather data suggests prolonged rain, it can tip you off to possible flooding and give you time to shore up your building’s defenses against it.

For example, using local weather data one can identify the flood potential, which can save important equipment and electrical systems.

Hence, it becomes vital to combine IoT with HVAC Systems to save on operational expenditure, easy retrofits, and increased efficiency. MG Cooling Solutions help in bringing such recent HVAC technologies for its customers.

 

 

How an HVAC Consultant can save cost for HVAC Systems ?

The role of an HVAC Consultant is critical for HVAC Projects. The economics of HVAC systems include capital costs and operating costs. The operating cost comprises power consumption, AMC maintenance, and repair, recommissioning, replacement if required.

HVAC Consultant

Usually, a  life cycle cost of any HVAC equipment can be broken down as :

Lifecycle cost (LCC) = first cost + maintenance and repair + energy + water + replacement – salvage value

HVAC Consultant determines the best HVAC systems depending on the facility and premises where the HVAC system is required. They economically evaluate various options like simple payback, net savings, savings-to-investment ratio (SIR), adjusted internal rate of return (IROR), and discounted payback to check the economical HVAC system.

The economics of HVAC systems can be broken into capital expenditures (CAPEX) and operating expenditures (OPEX).

The HVAC systems that meet the energy code are considered the best option. Simply using R-values without defining the construction materials is not a good HVAC Consultancy practice. The thermal mass, vapor barrier, and envelope leakage will affect the capacity, configuration, and performance of HVAC systems. An HVAC Consultant that does not respond to the individual material characteristics of a building can make the system run badly. This will lead to underperforming causing an impact on energy consumption, premature equipment failure, and occupant discomfort.

A good HVAC Consultant should not use rules of thumb to establish air handling system airflow, chiller plant capacity, and heating plant capacity. Often, the initial HVAC equipment sizes are adjusted to satisfy the engineering calculated heating/cooling peak demand. However, HVAC Consultant must consider any diversity in operating the HVAC systems to represent real occupancy to adjust HVAC equipment and distribution systems’ capacities. At the end of the design development phase, updated equipment selections are made and finalized.

So what does this has to do with the economics of HVAC systems? If HVAC Consultants use the rule on the thumb, the HVAC system capacities end up significantly higher and oversized as they were never adjusted for the refined load calculations and diversity of operation. This causes a huge expense on CAPEX. The impact on OPEX will lead to unsatisfied hours of operation or underperformance of the HVAC system, early equipment failure, inefficient operation (increasing operating expenses), and occupant discomfort.

 

Hence, any company must choose HVAC Consultant which are professional and are complying with ASHRAE codes and standards to save on CAPEX & OPEX. MG Cooling Solutions are HVAC Consultant who follows ASHRAE codes and standards to deliver energy efficient and cost efficient HVAC Projects.

How should an HVAC Installation Company takes care of life saving dampers?

A good HVAC Installation Company must follow code and standards for all the materials and all equipment.

HVAC Installation Company
 HVAC Installation Company

This article will talk about life-saving dampers which are a part of HVAC Installation.HVAC Dampers are common in every kind of facility, whether it is a  single building or a university, Business house, offices, healthcare complex when it comes to life safety dampers. Hence, good HVAC Installation Company should do the proper installation, operation, and maintenance validated and tested from the beginning to the end of the life safety damper life by HVAC Consultants.

DESIGN AND INSTALLATION CONSIDERATIONS

When an HVAC Consultant designs the HVAC system, one of the most critical coordination issues with the HVAC Installation Company is understanding where all the rated walls and assemblies, openings are so that the proper life safety damper products can be incorporated into the HVAC system design

MAINTENANCE

The HVAC Installation Company must not only be sensitive to the maintenance access to life safety dampers but also the assemblies specified for walls, floors, ceilings, roofs, and shafts that will affect the types of life safety dampers required. If dampers do not work well, for any reason, the engineer, architect, contractor, and even the AHJ have liability. Maintainability begins with product design and proper accessibility. In general, fuse links are not required to be replaced when testing, but if the link is damaged or painted, it should be replaced. The links should be replaced with the same size, temperature, and load rating.

CODES AND STANDARDS

Compliance with codes and standards is the minimum requirement for any HVAC Installation Company.

INSPECTION AND TESTING

One of the biggest risks beyond the damper not working when required is that the building insurance company could indeed possibly refuse to cover the loss of property or even loss of life in a litigation case if the dampers were not properly installed, tested, and maintained.Each damper should be inspected and tested by an HVAC Installation company.

Operational testing which includes all fire, smoke, combination fire smoke, and ceiling radiation dampers and their installed components (fuse links, limit switches, smoke detectors) must be done. There are three times when the services of an HVAC Installation Company are required.

  • The first test is to be done after installation to verify that the damper is installed correctly and there are no obstructions keeping the damper from opening and closing as required prior to the building occupancy.
  • The second test and inspection of each damper is one year after installation to verify that the damper has no interference due to rust, bent, misaligned, or damaged parts during the construction phase of the building or debris that may have somehow lodged in the damper that would prevent proper operation.
  • After that, maintenance people must be trained to check them periodically.

RECORDS  A good HVAC Installation Company must provide its client

  • the damper location
  • the type of damper (fire, smoke, combination fire/smoke, and ceiling radiation damper, etc.)
  • Date of inspection
  • Name of the company doing the inspection and testing
  • Person or persons that are inspecting and testing
  • Description of the damper condition
  • Description of each deficiency or discovery of the improper condition

Life safety dampers indeed are one of the most important products in an HVAC system. Proper installation, operation, and maintenance must be a priority of the HVAC Installation Company and others like an architect, engineer, contractors, and especially the owner. MG Cooling Solutions is one such HVAC Company which takes care of all HVAC Installation codes and practices.

What are the right Ventilation strategies adopted by HVAC Consulting Companies ?

HVAC Consulting Companies refer to ASHRAE code  62.1–2016 which talks about Ventilation for Acceptable Indoor Air Quality. It talks about reducing the amount of necessary outside air that needs to be conditioned for acceptable indoor conditions, and there are several ways by which HVAC Consulting Companies can do this as per ASHRAE Standard.

Image result for hvac consultancy companies

 

Below mentioned are some ways and strategies HVAC Consulting Companies deploy to save energy and money

Occupant diversity

People inside a room will contaminate indoor air by activities like exhaling carbon dioxide, sweating, coughing, etc. Again the premises have contamination that comes from paint, carpet, upholstery, and other fixtures, furniture, which emit minute particles and vapors, all of which are already mentioned into the mathematic formulas found in ASHRAE 62.1-2016, the standard that regulates outdoor air.

For example, a large office space with a capacity for 100 people and five conference rooms accommodating up to 20 occupants each and a cafeteria accommodating 50 people will be used throughout. Hence, a building which has a total of 100 employees those 100 people are either at a desk, in a private office, in the cafeteria, or sitting in a conference room, but not occupying two spaces at once.

 

Hence, it is not necessary to design a building for every person that every room is designed to accommodate, but the HVAC Consulting Company must include a reasonable approximation of the expected use of the building by every occupant and employee.

Time Averaging

ASHRAE 62.1-2016 Section 6.2.6.2 allows HVAC Consulting Companies to account for situations where the occupancy matters as a period of time. For example, depending on the nature of the organization and its employees, some people may occupy a space for a short period of time or vice versa. Time averaging is the process through which  HVAC Consulting Companies solves this problem. For example, a conference room often sits completely empty but is occasionally full for a short period of time. Imagine, a meeting will last for only 30-45 minutes, requiring occupied outdoor-air ventilation for those 30-45 minutes. However, the prescriptive formulas would indicate the need for full ventilation resulting in an overventilated room. By focusing on the amount of time people are staying in space, the required outdoor-air requirements can be reduced anywhere from 30% to 50%.

Similarly, retail spaces and restaurants are the places where the occupancy varies depending on the day or time. Hence, it is imperative for  good HVAC Consultancy Companies to derive meaningful energy savings by designing the right system for space

Hence, there is a cost saving approach as there is a huge potential for a reduction in electrical system design sizing, such as smaller wire sizes, smaller circuits ampacity, reduced electric operating demand kilowatts, as well as electrical energy-consumption reductions.

Real-time air monitoring using CO2 sensing

Referring  ASHRAE 62.1-2016 Section 6.2.7, it talks about the use of sensors that collect data in a specific zone and communicate the information in real time to the HVAC control system, which then makes immediate adjustments in the ventilation airflow. The most common application of Demand Control Ventilation ( DCV) uses carbon dioxide (CO2) sensors to determine if people who are occupying a room are creating a condition of excessive carbon dioxide and negative oxygen and, if so, remediate it immediately with increased outdoor air, and is constantly being sampled and treated, not allowing CO2 a chance to concentrate above a predetermined “high value. ASHRAE 62.1-2016 6.2.7.1.1 describes the allowance for outdoor airflow reset in response to system population. When using a DCV system, the HVAC Consulting Companies must determine what airflow range is appropriate for the zone and for the system.

 

Often, a value of 1,000 parts per million (ppm) CO2 is considered adequate for the dynamic-reset high CO2 value. However, in urban areas, the ambient outdoor-air CO2 concentration may be much closer to 1,000 ppm, and in such cases, the HVAC Consultancy Company should consider how this higher ambient CO2 may impact the high-value setpoint as well as the reset values for outdoor airflow.

Ideally, these CO2 sensors are used in areas that have the potential of being densely but intermittently occupied, such as in cafeterias, auditoriums, gymnasiums, and conference rooms. The sensors may not provide a quantifiable benefit for other spaces, such as open-office or reception areas, due to the smaller number of occupants per unit of area

Real-time monitoring through occupancy sensing

The final strategy is using DCV with occupancy sensors. These devices are always monitoring. When there is motion in a space that triggers the sensors, the building automation system responds accordingly. Motion sensors are commonly used in other applications, such as lights that trigger automatically when a customer enters a store restroom or security lights that turn on or brighten when a person walks by.

 

The CONCLUSION
The savings that can be realized upon implementation of any or all of the strategies described above can be in first cost ( i.e. capital expenditure) and operating cost. Smaller outdoor-air ventilation system size can result in a smaller heating or cooling plant and smaller equipment. Smaller equipment leads to smaller duct and/or piping as well as reductions in electrical wire sizing and circuit breakers.  Operationally, the reduced outdoor airflow saves costs throughout the life of the equipment and the building through smaller operating horsepower of pumps and fans supplying and conditioning the outdoor air.  Hence, implementing these strategies by HVAC Consulting Companies maximize energy efficiency in HVAC systems can add up, quickly resulting in appreciable savings for its clients.

MG Cooling Solutions, an HVAC Consulting Company makes sure that it uses all the strategies or in their combination for better results.

What are recent HVAC technologies adopted by HVAC Companies ?

Recent HVAC Technologies & Trends

HVAC Companies need to evolve themselves as per recent HVAC technologies. They must constantly innovate their processes to stay updated with recent HVAC technologies.

MG Cooling Solutions
HVAC technologies

An indoor comfortable temperature is important for any office space or building and it’s driven by your HVAC system. Since HVAC systems are the biggest consumers of total energy, new trends and technologies in HVAC are turning their focus toward creating efficient HVAC systems

HVAC technology is becoming more sophisticated, built with better algorithms and able to gather more data..” With that in mind, here are five trends in the HVAC industry that aim to help improve the efficiency of your building.

 

  1. Smart Controls HVAC controls are now being built with more precise sensors. “There are a lot more sensors gathering information about what’s actually going on by identifying the level of activity that’s actually occurring in the building and then modulating the equipment for optimal usage.” For example, CO2 sensors can use occupancy information to appropriately ventilate a space as and when required. This is again a gig energy saver which shows smart controls have definitely come a long way and they are going to be better with time.
  2. Geothermal Systems do not use oil or gas, rather geothermal heat pumps are fuelled by the earth itself by using earth’s thermal energy around the year as it remains consistent, to heat and cool a space. The cost of installing a geothermal system is higher than the HVAC equipment. But one must conscious of looking at the overall lifetime operating cost, maintenance cost, etc.
  3. Integration The industry is also seeing greater integration of HVAC controls with other building controls and BMS. For example, particularly advanced lighting, a sensor in a room might be used to control the lighting in that space, as well as the operation of HVAC. Access controls which are used for security can also be compatible with HVAC controls.
  4. Variable Speed Controls Usually HVAC systems are traditionally designed to operate at peak load – the biggest expected heating or cooling load. The HVAC  industry, therefore, is seeing an opportunity in variable speed controls which are more effective. This makes HVAC  equipment very efficient at operating at those variable load conditions causing higher efficiency and less waste.
  5. Variable Refrigerant Flow (VRF) Systems have seen growth as they have higher capital expenditure but also have low ongoing energy and maintenance costs.VRF shows great energy efficiency as in a weekend when there is no occupancy comparing to Monday when all the employees turn up.

MG Cooling Solutions always help its customers in with recent HVAC technologies to help its clients in saving huge money and efficient HVAC projects.

 

How to improve HVAC efficiency by hiring an HVAC Company for coils ?

To increase HVAC efficiency, coil cleaning is a much-needed service for every industrial customer. For an HVAC System, Coils are everywhere from evaporators to condensers, reheat, heat recovery, heating, process, chiller, cooling towers, and refrigeration

HVAC Coil cleaning is crucial
HVAC Coil cleaning is crucial

Coils need to be cleaned regularly as coils get dirty every day due to improper installation, inadequate prefilters, no filters, leaking filter racks and dirty operating environments. Coils need to be cleaned monthly, quarterly or yearly cleaning, depending on the operating environment by the HVAC technicians to increase HVAC efficiency.  Dirty coils can lead to:

■ Replacement of the coil sets

■ Increased run time on HVAC equipment and hence decreasing HVAC Efficiency

■ Inefficient chiller operation by improper HVAC supervision

■ Excess chiller wear and tear thus impacting overall HVAC Efficiency

■ Loss of compressors efficiency and fan motors

■ Rising Energy bills

■ Poor indoor air quality

■ Microbial and bacterial growth (humidity) hinders the water-shedding ability of the coil

■ Improper airflow distribution

■ Non-maintenance of ambient temperature

HVAC consumes typically 50 percent or more of a facility’s monthly bills. You will get a big incentive for proper maintenance through a professional HVAC Company. There is a direct verifiable return on investment for coil cleaning as proved by a study from the American Society of Heating, Refrigerating and AirConditioning Engineers ( ASHRAE)

Dirty HVAC coils can lead to numerous HVAC system problems as well as make building occupants uncomfortable due to inefficient HVAC System. Clean coils help ensure peak system performance and occupant comfort.

Hazards of not cleaning coils

A hidden enemy and substance known as “biofilm,” grow deep inside the coil sets is a common unnoticed problem. Make sure that your HVAC technicians clean the coil within and just not make it shiny or glossy.

Biofilm is a complex microbial layer growing on coils and drain pipes. It’s composed of different microorganisms adhering to surfaces coming out of various processes running indie the HVAC system. These microorganisms can stick together and acts as an insulator on the coil surface, affecting the temperature and airflow, thus impacting HVAC efficiency. This leads to occupant complaining for the inefficiency of HVAC systems and serious health hazards arising out of various by-products like volatile organic compounds etc.

Solutions to increase HVAC Efficiency for Coils

Prevention: It means proper filtration and fixes leaks, gaps in filters and gaps in filter racks. Prefilters may be needed in some cases depending upon the operational environment and pleated filters could also be considered.

Cleaning: Regular cleaning can help in increasing the efficiency of coils and HVAC System to preserve expensive coil sets. In fact, regular coil cleaning and monitoring can solve most of the issues discussed in this article.

Treatment: There are certain sprays and products which can also inhibit biological growth. A proper HVAC Company with trained HVAC technicians can help in improving HVAC efficiency. Some coils can be cleaned easily, some need coil-cleaning chemicals and a spray wand.

Proper HVAC system maintenance makes HVAC systems energy efficient as well as improve the health of building occupants. Hence, a good HVAC Company like MG Cooling Solutions can take care of minute details and help in saving money for its customers.

 

 

Right HVAC Consultancy to detect Occupancy in the premises

HVAC Consultancy Companies using sensors to detect occupancy and saving energy.

Image result for hvac consultancy

The role of HVAC Consultancy Company is to do the right calculations for energy efficient HVAC Projects. One of the factors to do is by calculating occupancy, i.e. the number of people presents inside the facility. HVAC (Heating, Ventilation & Air Conditioning) are present in every kind of building. Most of the HVAC Consulting Companies do engineering to air condition the area assuming maximum occupancy rather than actual usage. As a result, HVAC facilities are often over-conditioned needlessly. Thus, in order to achieve efficient air conditioning, HVAC Consulting Companies must require knowledge of occupancy.

Technologies advancement for HVAC Consultancy Companies

This article by MG Cooling Solutions ( An HVAC Company) shows how real-time occupancy data from a wireless sensor network can be used to create occupancy models, which in turn can be integrated into building conditioning system for usage-based demand control conditioning strategies. Using strategies based on sensor network occupancy model predictions, we show that it is possible to achieve 42% annual energy savings while still maintaining American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) comfort standards.

Studies suggest that 15% to 25% of HVAC energy can be saved by setting ventilation rates based on actual occupancy. Currently, the majority of HVAC Consultancy Companies condition rooms assuming maximum occupancy during normal working hours and are turned off at night. This leads to inefficiency as rooms are often conditioned to levels that are not appropriate for the number of occupants actually occupying the areas.

Image result for hvac consultancy

Increasing Efficiency through incorporating sensors

To increase the efficiency of HVAC systems, a system for detecting occupancy is needed to condition rooms appropriate to usage. Though there are several methods that are commonly used for detecting occupancy within modern buildings, these methods present limitations. Passive infrared (PIR) sensors, commonly used for controlling lighting, are a simple way of detecting if a room is occupied or not but do not give information regarding how many people occupy the room.

This information is necessary for CO2 ventilation. Using CO2 sensors directly for regulating CO2 is also unsuitable for conditioning strategies. CO2 buildup is slow, and by the time sensors detect high levels of CO2 that trigger ventilation, occupants of the room are likely to already feel uncomfortable  If not properly calibrated, these sensors can also be inaccurate. Electrical loads have also been used for occupancy estimation.

Hence, a good HVAC Consulting Company can help in saving money for its customers through the latest technology. MG Cooling Solutions is one such HVAC Company and can be reached at www.mgcs.net.in

 

 

Major Considerations in HVAC Design

Major parameters for HVAC design  by looking at different processes  and their environmental impact include the following:

Image result for hvac design parameters

Temperature.

Temperature is sensible heat that can be felt or sensed because it causes a rise or fall in temperature.

 Humidity

It is an indication of the level of water vapor in the air. Humidity is typically expressed as relative humidity. HVAC and facility professionals utilize dew point to indicate moisture content. A psychrometric chart is a necessary tool for understanding the current state of the air and water vapor mixture.

 Particulate contamination.

Particle load may occur from the outside or from within the facility. The wind and the season can play big parts in contributing to the amount of particulate in the air being introduced into an HVAC system. Internal particulate loading can come from people, corrugate, facility materials of construction, and manufacturing or testing contaminants. Particulate can be viable or non-viable and have their potential hazards to the facility environment.

Vapor contamination

Vapor contamination can come from internal and external sources similar to particulate contamination. An HVAC system near a highway can draw in detectable levels of hydrocarbons. A diesel engine inadvertently can bring odors and vapors into warehouses, offices, laboratories, and manufacturing areas served by the unit, causing discomfort or illness to the building occupants. Improper amounts of outside ventilation air can cause carbon dioxide build-up with resulting oxygen deprivation concerns.

 Pressure

Air pressure is assumed to be incompressible in most HVAC applications. Sites located in higher elevations must also not make the same assumptions that those living nearer to sea level make about system component selection.

Safety

Safety is an important system capability often assumed or not adequately considered. Fire protection considerations, adequate ventilation for personnel, fail-safe automatic controls, hazardous fume, and particulate containment devices, and properly designed egress are among many facility safety concerns.

Image result for hvac design parameters

 Other considerations for HVAC Design include the following:

* Ratio of outside air (OA) to return (recirculated) air (% OA)

* Amount of air moving through the HVAC System relative to the amount of air needed to heat and cool the facility

* Localized heat, humidity, and particulate issues within a facility

* Efficiency of air distribution and circulation within a facility.

Thermostats for HVAC Controls & Automations

Thermostats for HVAC Controls & Automation| Setting the right HVAC temperature |
What are Thermostats?
Thermostats are the devices used for HVAC Control & Automation
Thermostats typically regulate the use of central HVAC systems by enabling users to specify the desired setpoint temperature and then cycling the system on and off to maintain the temperature within a fixed range of the setpoint. The simplest type of thermostat for HVAC Controls & Automation requires users to manually switch the HVAC system on and place it into heating or cooling mode, as well as specify the desired temperature.

Image result for hvac controls
Drawbacks of Manual Thermostats
Manual thermostats, while simple and inexpensive, are
(i) prone to human error, since users may forget to turn them off when leaving for an extended period, and
(ii) reduce user comfort, since users cannot activate them in advance of their arrival, causing an initial period of discomfort on entry as the room or office heats up or cools down to the setpoint.

What are programmable thermostats for HVAC Control & Automation?
To address these drawbacks, most modern thermostats are programmable. A programmable thermostat enables a user to manually program a thermostat schedule, which specifies the time each day the HVAC system should be on and its corresponding setpoint temperature.
HVAC technicians in offices derive a schedule based on when they expect to be home and away. If a user’s expectations are correct, then a programmable thermostat can reduce human error by automatically turning off (or adjusting the setpoint) when a user leaves.
To increase comfort, users may also enter schedules that pre-cool or pre-heat a home (or room) in advance of their expected arrival. Programmable thermostats are simple and cheap devices present in tens of millions of homes. While programmable thermostats are marketed for their potential energy savings.

Image result for thermostats
Challenges with programmable thermostats
Unfortunately, the interface to many programmable thermostats is difficult to navigate and tedious to program, which often discourages users from ever programming them. Even when taking the time to program a schedule, users are left with the complex task of determining a static schedule that optimizes their energy savings and comfort given their occupancy pattern, which may be dynamic and difficult to predict.
Further, since daily activities and, thus, occupancy patterns inevitably change over time, e.g., summer activities differ from winter activities, users must periodically re-program their thermostat as their optimal schedule changes, or risk losing any of its energy-saving benefits.
Rise of smart thermostats on sensor technology
As a result of these challenges, many users avoid programming thermostats, which defeats their purpose. Smart thermostats, which are useful in HVAC Controls & Automation sense occupancy and automatically program a schedule without user intervention, were introduced to address the drawbacks of programmable thermostats. However, smart thermostats are still niche devices for energy-efficiency enthusiasts, largely due to their high cost and the overhead of installing them of millions of “dumb” programmable thermostats will remain in homes for many years to come.

HVAC Technologies & Innovations to be adopted by HVAC Companies for energy efficient HVAC Projects

Upcoming HVAC Technologies & Innovations adopted by HVAC Companies for energy efficient HVAC Projects

A good HVAC Company must keep itself updated with recent HVAC Technologies & Innovations to deliver successful cost efficient and energy efficient HVAC Projects.

Image result for hvac technologies

Despite rising energy costs and expanding carbon footprints, “cutting-edge” heating, air conditioning, and ventilation (HVAC) technologies face an uphill battle for adoption by the current HVAC industry, according to a Research.  A survey is done in the field of incumbent and emerging HVAC technologies in terms of geographical, regulatory, and economic factors influencing adoption in the current scenario and assesses which systems and components are best positioned for future growth.

Why we need new technologies in HVAC Systems?

Building HVAC systems consume 13 percent of all primary energy generated around the globe, hence HVAC Consultants across the globe are looking out for new, more energy-efficient HVAC equipment.

This includes advanced heat pumps, absorption chillers, evaporative chillers, and condensing boilers. In addition, there’s a demand for component technologies that improve the operational cost or performance of existing HVAC equipment. This includes variable speed compressors, electronic expansion valves, advanced humidity removal, heat recycling, variable frequency drives, and thermal energy storage.

Image result for hvac technologies

New Technologies and research in HVAC Industry

While some HVAC Companies will choose to install whole new, cutting-edge HVAC systems, but others will favor lower-cost incremental component solutions that improve the efficiency of their existing systems

Component technologies demonstrate the quickest return on investment, smoothing their path to adoption. We further evaluate HVAC systems and components separately and scores technologies on their technical value and maturity. Hence, plotting each technology’s relative potential on a matrix comprising four quadrants: Current Winners, Future Winners, Long-Shot, and Faded Incumbents.

Key Findings of the research:  Current Winners

-Advanced HVAC systems are seeing incremental adoption. Yesterday’s steam-heated boilers and standard furnaces are slowly giving way to more efficient gas-fired furnaces and condensing boilers, as well as new technologies like radiant heating and advanced heat-pumps.

Heat pumps show particular potential when coupled with water heaters, as this approach – combines the efficiency of electrically driven pumps with advanced absorption cycles.

Opportunities abound for advanced HVAC components to show their value. Simplicity can shorten the path to adoption, as illustrated by component-level solutions such as variable frequency drives (VFDs) and expansion valves. Rated a Current Winner, low-cost VFDs enable compressors to pump only what is needed for specific applications, significantly improving the efficiency of chillers; most see payback periods of 2.5 years or less.

Key Findings of the research:  Future Winners

Expansion valves, meanwhile, rank among the Future Winners, thanks to their ability to reduce the energy consumption of air conditioning systems and boilers and their very attractive payback periods.  -The value of integrated HVAC technologies can exceed the sum of their parts. Many of the report’s highest ranked HVAC technologies can deliver even better returns when combined. Using expansion valves with membrane-based air-quality and humidity-control technologies, for example, can reduce HVAC energy consumption by 40 percent without a significant capital cost. Developers that can pool the value of their HVAC technologies through integration will also see their commercial opportunities multiply.
