How Refrigerant Works to Keep Your Home Cool in the Summer by Air Authority

When it comes to your air conditioner, you’ve probably heard a lot about refrigerants. But what is refrigerant, and how does it work to keep your home cool during those hot summer months? To help you understand how your AC works and why maintaining a correct refrigerant level is essential, let’s dive into a quick explanation from the experts at Air Authority.

What Is Refrigerant?

Refrigerant is a chemical compound that can easily change between liquid and gas vapors at specific temperatures. The change is so easy because it absorbs environmental heat from one space and releases it into another room.

There Are Different Types of Refrigerants Used in Air Conditioners:

  • Chlorofluorocarbons
    • AC manufacturers stopped using this type of refrigerant because it was linked to harmful greenhouse gas emissions. Production stopped in 1994.
  • R22
    • This type of refrigerant is also known as Freon and it has been used in air conditioners for many years. However, evidence has also shown that it’s harmful to the ozone so it is no longer used by manufacturers and HVAC technicians.
  • R410A
    • Also known as Puron, this type of refrigerant is the replacement for Freon. Unlike R22, Puron does not contain chlorine and, as a result, it produces fewer greenhouse gas emissions. Puron is also more efficient than Freon.

How Does Refrigerant Work In An Air Conditioner?

Contrary to what you might assume, your air conditioner does not create cold air. Instead, it removes the heat from your home. Essentially, as refrigerant changes from a liquid to a gas and back, it absorbs the heat from the air inside your home and releases it outside. Here’s how it works:

  • First
    • Air from your home moves over the evaporator coil, located inside your home’s indoor AC unit. The coil absorbs the heat from the air with the refrigerant that’s inside your AC.
  • Then
    • The refrigerant in the coil flows to the warm condenser coil (located in your outdoor AC unit), where the compressor pressurizes the refrigerant (makes it very hot). Since the temperature of the refrigerant is warmer than the temperature of the air outside your home, the outside air absorbs the heat from the refrigerant.
  • Finally
    • Once the weather of the refrigerant cools down, it flows back inside your home to absorb more heat and repeat the cycle. The refrigerant will continue to flow back and forth until the air in your house reaches the temperature you’ve set on your thermostat.
