How Does an Air Conditioner Work?07/18/2016 The temperatures are hitting record highs across the U.S. and many homes are utilizing some type of air conditioner to combat the smoldering heat. Although we are all thankful that your air conditioner runs, the team at Air Max HVAC Inc in Thousand Oaks would like to tell you how it works. The Basics There’s a plethora of science regarding keeping your home cool. Your air conditioner runs in a parallel way to your refrigerator, of course your AC has a more difficult task to tackle. 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 easily 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 the place your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be located inside your home, in your garage or sometimes in your attic. Warm air moves across the cold evaporator coil and the heat is taken 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 understand that it’s not as top-priority to you how it works, but that it’s working.
