Water-to-water heat pump systems, as the name suggests, transfer heat between two water sources. Typically, these systems are used in conjunction with a boiler or cooling tower which serves as the primary source of water for heating or cooling. A closer look at how they work, their advantages, and disadvantages can provide more insight into their functionality and use.
How Water-to-Water Heat Pump Systems Work
Water-to-water heat pumps operate on the principle of refrigeration cycle, using a refrigerant to transfer heat between the two water sources. The cycle consists of four main components: compressor, condenser, expansion valve and evaporator.
During the heating mode, the refrigerant absorbs heat from a low-temperature source (like an outdoor water source or ground) in the evaporator coil. It then moves to the compressor, where it is pressurized and its temperature elevated. The high-temperature refrigerant then travels to the condenser coil where it releases its heat into a high-temperature sink (like an indoor water tank). Finally, it passes through an expansion valve that reduces its pressure before returning to the evaporator.
During cooling mode, this process is reversed: heat is absorbed from indoor air and released outdoors.
