The weather is hitting record figures throughout the states and most homes are running some variety of air conditioner to beat the summer heat. Although we are all grateful that your air conditioner runs, the professionals at Four Seasons Air Conditioning and Heating LLC in Kingsville would like to tell you how it works.
There’s a lot of science behind keeping your living space cool. Your air conditioner functions in a similar way to your refrigerator, however your cooling system has a larger responsibility to tackle. Both your fridge and AC cool with a reoccurring loop of refrigerant, however with the air conditioner this refrigerant loops from inside to the outdoors. This refrigerant easily changes from a liquid to gas and back to a liquid again. It goes into your house as a sub-cooled liquid and as it evaporates it takes in heat from inside the home and turns back into vapor. This vapor then moves back to the unit outside where the heat is freed and is then condensed back into a sub-cooled liquid.
There are 4 central sections 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 in the home, in your garage or possibly in your attic. Warm air transports across the cold evaporator coil and the heat is taken from the air. This cooled air is then released throughout the space inside your home.
Your compressor sits in your outdoor condensing unit. The super-heated vapor from your evaporator coil flows into the compressor which surges the pressure of the vapor until it is transformed 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 moved outdoors and the refrigerant is adapted back into a sub-cooled liquid. The sub-cooled liquid then goes back to the indoor evaporator coil via an expansion valve or metering device. This continues repeatedly throughout the process.
That concludes your physics lesson today…your air conditioner functions on an endless loop of science. We know that it’s not as important to you how it works, but just the fact it’s running.
