Water source heat pump (WSHP) is a type of heating, ventilation, and air conditioning (HVAC) system that uses water as the heat transfer medium. WSHPs extract heat from a water source, such as a lake, river, or well, and use it to provide heating and cooling for a building.
The heat pump works by absorbing heat from the water source and transferring it to a refrigerant. The refrigerant is then compressed, which increases its temperature, and the heat is transferred to the indoor air through a heat exchanger. In the summer, the process can be reversed, with heat from the indoor air being transferred to the refrigerant and released into the water source, providing cooling for the building.
WSHPs are highly efficient and can provide both heating and cooling, making them a popular choice for commercial and residential buildings. They are also relatively easy to install and can be used in a variety of buildings, including those with limited outdoor space.
One of the potential drawbacks of WSHPs is that they require a water source, which may not be available in all areas. In addition, the efficiency of the system can be affected by the temperature of the water source, and extreme temperatures can also impact the performance of the system.
It’s important to work with a qualified HVAC professional to ensure that a WSHP is properly sized and installed for optimal performance. Proper maintenance and regular inspections are also important for ensuring the safe and efficient operation of a water source heat pump.
