This week on Tech Tips we’re breaking down how your AC works and how your home goes from hot to cold with the push of a button!
So let’s break this down into steps, so we can walk through the process it takes to cool down your home.
Step 1: Heat is absorbed by the evaporator coil
The warm air inside your house is drawn in through a vent and blows over the cold evaporator coil. The evaporator coil is the station located indoors and absorbs heat from the air, cooling the air. A fan blows the cold air into air ducts that distribute it throughout your home.As the refrigerant absorbs the heat from the passing air, it changes from a liquid state to a gaseous state and continues to travel along the loop system toward the compressor
Step 2: Compressor raises the refrigerant temperature
The compressor decreases the gas’ volume. Usually this is done by squeezing the gas tightly between two solid objects. This raises the pressure and temperature of the refrigerant, preparing it for the condensing process.
Step 3: Heat is transferred outside
The refrigerant, now a superheated vapor, reaches the condenser (which is located outdoors) and is exposed to the outside air. The outside air absorbs the heat from the refrigerant, lowering the temperature of the refrigerant and changing the state from a gas back into a liquid.
Step 4: Refrigerant gets cold; process repeats
Once the heat from the refrigerant is removed to the outdoors, the cold refrigerant travels back indoors to the evaporator to repeat the process over again. The process continues until the inside temperature of your home reaches your desired level. At this point, your thermostat tells your AC to shut off.
So much like we all learned in science class, your AC system functions by phase change and heat dissipation. It doesn’t just blow cold air, it’s removing the warm air from inside your home.
