Warning: Errors which can result in damage to equipment and void warranties. Design Guide Section 1 WattMaster WHP General Information Water Source Heat Pump Units A water source heat pump is a self-contained water-cooled packaged heating and cooling unit with a reversible refrigerant cycle. Its components 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. Design Guide WattMaster WHP Section 1 Design Guide 1-3 Figure 1-1: Typical Water Source Heat Pump 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 ...
