Water Source Heat Pump Unit
A water source heat pump is a self-contained water-cooled packaged
heating and cooling unit with a reversible refrigerant cycle. Its compo-
nents are typically enclosed in a common casing, and include a tube-
in-tube heat exchanger, a heating/cooling coil, a compressor, a fan, a
reversing valve and controls.
During the cooling mode, the tube-in-tube heat exchanger functions
as a condenser and the coil as an evaporator. In heating mode, the
tube-in-tube heat exchanger functions as an evaporator and the coil
as a condenser. A reversing valve is installed in the refrigerant circuit
permitting changeover from heating to cooling, and vice versa. The
condenser and evaporator tubes are designed to accept hot and cold
refrigerant liquid or gas.
