Source vs. Load

The model WPWD water-to-water system contains two water to refrig- erant heat exchangers. The two heat exchangers enable the system to be divided into a source and load separation.

The “source side” heat exchanger performs as in a standard water to air heat pump system. The source is typically supplied through a cooling tower, boiler, closed loop, or open well system. During the refrigeration cycle, heat is transferred from the

source side heat exchanger to the load side heat exchanger.

The “load side” heat exchanger takes the place of a DX (direct ex- pansion) air coil. It provides treated fluid (hot or cold) to a mechanical device. These mechanical devices include designs such as radiant slab heating, hydronic coils, or fresh air ventilation units.

See Figure 9 for a basic schematic of source side verses load side of a water-to-water system.
