Understanding Air Conditioner Refrigerant

Air conditioner refrigerant is a chemical compound responsible for the heat transfer process in an air conditioning system. It circulates through the system, absorbing heat from indoor air and releasing it outside, resulting in a cooler indoor environment.

The refrigerant undergoes a continuous cycle of evaporation and condensation within the air conditioner. In the evaporator coil, the refrigerant absorbs heat from the indoor air, transforming from a low-pressure gas into a high-pressure gas. The warm air is then expelled, leaving behind cool air that is circulated back into your home.

After absorbing heat, the refrigerant travels to the condenser coil located outside your home. Here, it releases the heat it collected from the indoor air, returning to a liquid state. The process repeats as the refrigerant flows back into the evaporator coil to repeat the cycle.

It’s important to note that air conditioner refrigerant is a specialized substance that requires careful handling. Only trained professionals should handle refrigerant-related tasks, such as refilling or replacing refrigerant. This ensures that the system operates safely and efficiently.

Now that we have a basic understanding of how air conditioner refrigerant functions, let’s explore the different types available in the market.
