How Does an Air Conditioner Work?07/18/2016 The temperatures are climbing to record highs across the country and most homes are utilizing some variety of air conditioner to beat the seasonal heat. While we are all thankful that your air conditioner runs, the experts at Summit Air Conditioning Inc in West Palm Beach would like to teach you how it works. The Basics There’s a lot of science behind keeping your living space cool. Your air conditioner operates in a parallel way to your refrigerator, but your AC has a larger job to manage. Both your fridge and AC cool with a constant loop of refrigerant, in your air conditioner this refrigerant loops from inside to outside your home. This refrigerant quickly converts from a liquid to gas and back to a liquid again. It enters your home as a sub-cooled liquid and as it evaporates it absorbs heat from your indoor air and expands back into vapor. This vapor then moves back to your outdoor unit where the heat is let go and is then condensed back into a sub-cooled liquid. Four Components There are 4 main components to your air conditioner unit: a compressor, an evaporator coil, the condensing coil and an expansion valve. The evaporator coil is where your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be found inside your home, in your garage or sometimes in your attic. Warm air transports across the cold evaporator coil and the heat is separated from the air. This cooled air is then transferred throughout your home. Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil goes into the compressor which surges the pressure of the vapor until it is converted into hot, high pressure vapor. The hot vapor then goes back into the condenser coil where less hot outdoor air flows across the coil, heat is released outdoors and the refrigerant is converted back into a sub-cooled liquid. This sub-cooled liquid is then returned to the indoor evaporator coil and through an expansion valve or metering device. The process is then repeated. That completes your physics lesson of the day…your air conditioner runs on an endless loop of science. We know that it’s not as important to you how it works, but that it’s working.
