When I made the decision to have central air conditioning set up into my home, I started doing some looking around. I didn’t want to make such a huge investment without being informed about the equipment. I thought I had a seriously great system of how a ac device operated, however I was not correct on this. The majority of cooling units are mini split systems, which consists of an indoor air-handling component and an outdoor condensing unit. The indoor air handler houses a supply fan, a cooling coil, and the outdoor device. The outdoor component is made out of a compressor and a condenser coil. The a/c is programmed to cool and dehumidify indoor air by blowing it over a cold coil surface. The indoor coil is really made up of columns of tubes that use refrigerant through the coil. As the warm air passes over the indoor cooling coil, it then addes heat to the cold refrigerant and transforms it into a warm gas. The gas is then pushed from the coil to the compressor, and finally, the outdoor condenser. The heat is then changed over, creating condensate, as the refrigerant is pushed back into a liquid, and the process is really repeated over and over, creating a cooling effect in the house. The seasonal energy efficiency rating (SEER) illuminates how effectively the a/c manages the cooling process. The better the SEER rating, the more energy efficient the machinery is, and the lower the operational price tag.
