The temperatures are climbing to record highs across the country and the majority of homes are utilizing some variety of air conditioner to battle the summer heat. While we are all thankful that your air conditioner works, the experts at Brooks Heating and Air Conditioning in Bossier City thought they would give you a glance at how an air conditioner operates.
There’s plenty of science involved in keeping your house cool. Your air conditioner operates in a parallel way to your refrigerator, however your air conditioner has a bigger task 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 quickly alters from a liquid to gas and back to a liquid again. It goes into your home as a sub-cooled liquid and as it evaporates it soaks in heat from inside the home and turns back into vapor. This vapor then transfers back to the unit located outdoors where the heat is let go and is then condensed back into a sub-cooled liquid.
There are 4 central elements to your cooling system: 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 established in the home, in your garage or possibly in your attic. Warm air passes across the cold evaporator coil and the heat is separated from the air. This cooled air is then sent throughout your indoor space.
Your compressor is located in your outdoor condensing unit. The super-heated vapor from your evaporator coil enters into the compressor which raises the pressure of the vapor until it is converted into hot, high pressure vapor. The hot vapor then enters back into the condenser coil where less hot outdoor air flows across the coil, heat is moved outdoors and the refrigerant is changed back into a sub-cooled liquid. The sub-cooled liquid returns to the indoor evaporator coil by an expansion valve or metering device. This process is continually repeated.
That accomplishes your physics lesson today…your air conditioner runs on an endless loop of science. We realize that it’s not as crucial to you how it works, but just the fact it’s running.
