Reduce your air conditioning costs with us!


Article By MG Cooling Solutions In HVAC - August 7, 2020

Business and property owners always look for solutions to reduce the extra cost they are paying for maintaining an appropriate inside environment. To make your HVAC more energy efficient and to improve its performance and durability several techniques and technologies are available in the market today. One such HVAC technology is VRV or VRF, lets understand what these letters stand for. VRV stands for Variable Refrigerant volume and VRF stands for Variable refrigerant flow. These two different names represent the same basic technology, the only difference is VRV is invented by Daikin Industries, Ltd. In 1982 and trademarked the term VRV, when other companies developed the same technology, they had to change its name, so they used VRF. VRV/VRF is a large-scale ductless HVAC system that can perform at a hight-capacity, which provides simultaneous heating and cooling. Variable refrigerant flow (VRF) systems are known for their high energy performance and thus can improve the energy efficiency of HVAC in both residential and commercial buildings. MG cooling solution is a leading VRV/VRF air conditioner manufacturers, proving the best, eco-friendly, and pocket-friendly heating/cooling services for your facility.

VRV/VRF is a multi-split type of air conditioner that uses variable refrigerant flow control to provide the user with the ability to maintain individual zones control in each room and floor of an infrastructure. The compressor unit is controlled by a variable-speed drive. It uses refrigerant as the cooling and heating medium, this refrigerant is conditioned by a single outdoor condensing unit and is circulated inside the building to multiple fan-coil units (FCUs). It allows for many inside units to be connected to one outside. VRV/VRF can be integrated into emerging technologies such as building automation systems and the internet of things (IoT). VRV/VRF systems are of the following three types:

  • Cooling-only system, these systems provide only cooling and dehumidification
  • the heat pump system is a two-pipe system, in this, all the zones must either be all in cooling or all in heating
  • the heat recovery system is a three-pipe system, these systems can simultaneously heat certain zones while cooling others.

VRV/VRF system contains compressors having inverter technology, that allows the compressor to precisely adjust to the exact speed needed for heating or cooling, based on the environmental conditions as well as how indoor units are operating at any given time. VRV/VRF systems have a unique ability to extract heat out of the space requiring cooling and put it into zones requiring heating. They are noiseless in operations and indoor and outdoor units can be spaced as far as 200 feet apart. Some of the uses of this smart technology:

  1. It is best suited for spaces with inadequate cooling and heating capacity,
  2. Can be used for older buildings with limited space to install conventional HVAC equipment and ductwork,
  3. Suitable for new buildings where floor space is at a premium and free up floor space that is generally occupied by mechanical equipment,
  4. Can be used with inefficient HVAC systems with high operational costs
  5. Can be used with Variable Air Volume (VAV) systems with electric heat back-up,
  6. Best for buildings with significant heating requirements,
  7. Can be used in systems with inefficient fan operation,
  8. Useful for projects where energy star, LEED, BEAP or other energy efficiency certifications are required

VRV/VRF system has got a tremendous application in the following facilities to meet their specific heating and cooling requirements:


Education facilities have the unique challenges of diverse room types, whether it’s a vast college campus or a more intimate elementary school. For small admin offices to mid-size classrooms to large gymnasiums, all have different HVAC equipment requirements. With VRV/VRF systems it is possible to meet all these distinct needs with ease and it can be controlled through one control panel.


In hospitals and clinics, it is very important to maintain air quality and controlled temperature. The air can impact any patient’s recovery, and with VRV/VRF HVAC equipment, hospitals can meet the different heating/cooling needs of different rooms. A VRV/VRF system allows the lobby to be heated while recovery rooms can be kept cooler, it is easy to create zones with no duct leaks to worry about and provide more effective air filtration, preventing cross-air contamination.


With VRV/VRF systems installed in hotels, not only the customer can control the temperature while they are in the room, but also it can be controlled by managers to adjust the temperature as need and eliminate heating and cooling of empty spaces. Noiseless operation is another plus point for resting travellers


Such kind of facilities are the most challenging spaces for architects and engineers but with VRV/VRF systems, most of the restrictions that come with standard HVAC equipment can be eliminated. Smaller indoor and outdoor units, no long ductwork and individually controlled zones, these systems provide limitless options


VRV/VRF systems offer vast benefits to multi-family properties. The precision zoning provides each tenant to maintain their comfort level and even the building owners can reduce the flow in vacant apartments. These systems provide accurate, zone-by-zone energy usage reports


VRV/VRF systems provide consistent comfort and quiet operation that will help promote employee productivity. It provides flexibility in installation and a great option for tight spaces. These systems are pocket-friendly, and they tend to break down less frequently.

VRV/VRF system provides you with limitless possibilities and if you need an energy-efficient, durable, and flexible system then this system is the answer to all your problems and specific heating/cooling needs.
