1. The Evaporator Coil is a tube filled with water (Water Source Coil) and sealed inside of another larger tube filled with refrigerant Gas (Tube-In-A-Tube Heat Exchanger or a coaxial).
2. As the cold refrigerant Gas flows through the outside tube of the Evaporator Coil the water flowing through the inside tube of the Evaporator Coil warms the refrigerant Gas. (Purple) The heat pump cycle begins as cold liquid refrigerant passes through a heat exchanger and absorbs heat from the water circulating through the loop.
3. The Compressor then compresses the refrigerant Gas (The Gas that absorbed heat from the water circulating through the loop), causing it to become very hot and under high-pressure, raising its temperature to more than 160 degrees and pushes it into the Reversing Valve. (Red)
4. If the system thermostat is set to heating, then the Reversing Valve moves the hot high-pressure refrigerant Gas into the coil. (Red)
5. As the hot high-pressure refrigerant Gas moves through the Condenser Coil, the Fan blows air over the coil, heating the Conditioned Air Space and cooling the refrigerant Gas. The heat is removed from the refrigerant gas and transferred to air, which is then circulated into your house. (The temperature of the heated air or water is about 100 degrees.) The refrigerant gas cools and condenses into its liquid form as it moves through the Condenser Coil. (Pink)
6. When the cooled refrigerant Liquid moves through the Expansion Valve, the liquid evaporates back into its gaseous form in the Evaporator Coil and gets very cold in the evaporation process. (Blue)
Then the process starts over again.
