What is centralized air conditioning?
Centralized air conditioners are those air conditioning equipments that could circulate cool air through a supply system and return ducts. Registers and supply ducts carry cooled air from the air conditioner to the home. This cool air gets heated by circulating across the entire set up and then enters back the air conditioner through return ducts. Air conditioners also help to dehumidify the incoming air. A good practice is to use the circulating fans in individual rooms rather than making use of the system’s central fan for providing air circulation.
Air conditioner types:
Normally, a central air conditioner could be either a split or a packaged one. In case of a split-system central air conditioner, an outdoor metal cabinet contains the compressor and condenser. Also, there will be an indoor cabinet containing the evaporator. This equipment is primarily used for high utility commercial purposes and for cooling extremely large spaces. On the other hand, in a packaged central air conditioner, all the essential components such as the condenser, evaporator and compressor are all located in a single cabinet placed on a concrete slab or roof. This system is mainly used for residential and small commercial buildings.
Choosing the perfect central air conditioner:
Central air conditioners are extremely efficient compared to the conventional room air conditioners. They are very quiet, does not occupy house space and very easy to operate as well. Therefore, it is highly recommended to buy a central air conditioner that is energy efficient for saving your hard earned money. The efficiency of any air conditioners depends upon the installation procedure and proper size of the unit. The buyers must always choose a high efficiency central air conditioner model. It is also vital to choose a model with a higher SEER (Seasonal Energy Efficiency Ratio), which implies that the air conditioner will provide more cooling output with lower energy input.
Once the centralized air conditioner is fixed properly, it will definitely work hassle free for several years. Using duct-sizing methodology, providing enough supply registers, offering sufficient indoor space for maintenance and repair, sealing all ducts with duct mastic, keeping away the thermostat from other heat sources, installing duct work within the conditioned space, periodically refilling the refrigerant and properly placing the condensing unit in a confined space to avoid unnecessary noise disturbances are a few of the best practices to be employed during AC installation.
