How Does an Air Conditioner Cool the Air?

Air conditioners are quite a feat of engineering. While they seem to just blow cool air, there is actually much more going on than appears to the eye. Simply put, your air conditioner takes the hot air from your home, runs it through your air conditioning system, and then returns it as cool, dry air. So, what appears as cool air blowing into your home is actually the same air with the heat removed. Want to know how your air conditioning does this? Let the Millcreek air conditioning system specialists at Design Comfort explain how this happens.

Refrigerant

You may have heard your air conditioning specialist say the word “refrigerant” in regard to your air conditioner. Refrigerant is the chemical your air conditioner uses to facilitate the heat transfer process. It does this by completing a cycle in which it changes from a liquid to a gas and back again, taking on and then dispersing heat from the air within your home.

The 3 Main Components of Your Air Conditioner

Your air conditioner has 3 main parts: the compressor, the condenser and the evaporator. These components are responsible for changing the refrigerant from a liquid to a gas and back to a liquid, all within your air conditioning system.

How Do the Refrigerant and Components Work Together to Cool the Air?

In its different states, the refrigerant carries out heat and then helps to cool the air that is brought back into your home. How? When a liquid converts to gas, it absorbs heat. So when the refrigerant is in a gaseous state, it absorbs the heat from your property. As the refrigerant gas moves through the system, it passes through the outside unit, where the heat is released and the refrigerant cools. The cooled gas moves back into the house to the evaporator, where warm air is blown onto the evaporator coils now holding the cooled refrigerant. This creates chilled air, which is delivered to the inside of your property via the ductwork.

Removal of Humidity

In addition to lowering the temperature, your air conditioner does a second important job: it also removes humidity. Moisture is a conductor of heat, which is why humidity makes things feel so much hotter. As your air conditioner removes heat, it also removes moisture from the air and drains it outside your home. Without this function, you would have cool, moist air in your home rather than cool, dry air.

It’s a Complex System

Your air conditioner is a complex machine that benefits most when a licensed professional manages its maintenance and repairs.
