The Role of Heat Exchangers

What is a heat exchanger used for? An air source heat pump has two heat exchangers. The first is found in the exterior unit. A coil of tubing filled with refrigerant, it uses the principle of heat transfer to coax thermal energy from the air. Since the space inside the coil is filled with a liquid that is cooler than the surrounding air, thermal energy is drawn into the coil. This warms the refrigerant so that it transitions to a gas. In this form, the refrigerant travels into the house to the air source heat pump’s interior unit.

The heat pump’s interior unit contains a second heat exchanger that provides a transition point between the warmer temps inside the heat exchanger coil and the home’s relatively cool environment. Naturally, the heat energy that’s been carried inside the house seeks balance and begins moving from the area with more energy (the heat exchanger coil) to the area with less (your home). As a fan directs this warmth into the ductwork so that it can circulate through the house, the refrigerant cools and condenses back into a liquid. Then, the refrigerant returns to the outside unit to continue the cycle as needed in order to maintain the desired temperature inside the dwelling.
