How Does an Air Conditioner Work?07/18/2016 The temperatures are climbing to record figures across the U.S. and many homes are running some type of air conditioner to combat the seasonal heat. Although we are all grateful that your air conditioner runs, the team at Hopkins 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 home cool. Your air conditioner functions in a similar way to your refrigerator, however your AC has a more difficult job to manage. Both your fridge and AC cool with a reoccurring loop of refrigerant, in your air conditioner this refrigerant loops from inside to outside your home. This refrigerant effortlessly changes 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 soaks in heat from your indoor air and expands back into vapor. This vapor then travels back to your outdoor unit where the heat is released and is then condensed back into a sub-cooled liquid. Four Components There are 4 main sections to your air conditioner unit: a compressor, an evaporator coil, the condensing coil and an expansion valve. The evaporator coil is the location your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be established inside your home, in your garage or sometimes in your attic. Warm air transports through the cold evaporator coil and the heat is separated from the air. This cooled air is then sent 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 raises 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 relentless loop of science. We realize that it’s not as top-priority to you how it works, but that it’s working.
