The cooling agent, also known as refrigerant, transfers heat from your house outside the house. The closed system includes coils that hold the refrigerant. The coils transport the refrigerant through your house’s interior, outside of the house, and inside once again.
These components along the path adjust the refrigerant’s temperature, pressure, and condition to control where heat is absorbed or rejected. The components are an evaporator, condenser, and compressor.
