Ground source heat pump unit is a heating and cooling system that utilizes groundwater, lakes, rivers, and other water bodies as heat or cooling sources. It utilizes the relatively stable temperature of groundwater to extract or release energy from the ground through circulating water, achieving heating and cooling of buildings.
This type of unit includes the following main components: compressor, heat exchanger, expansion valve, and circulating water system. The compressor sucks in the working medium (usually refrigerant) at low temperature and pressure, and increases its temperature and pressure. Then, the high-temperature and high-pressure working fluid undergoes heat transfer and exchange with the circulating water through a heat exchanger, absorbing the residual heat inside the building in refrigeration mode and releasing it to the outside world; In heating mode, heat is absorbed from the outside and transferred to the interior of the building.
In addition, the system also has an important component - well site equipment. It consists of one or more extraction/injection wells and related pipelines, used to extract/inject groundwater into the wells to provide a stable heat or cold source.
Compared to other types of air source or ground source heat pump systems, water ground source heat pump units have more stable operating temperatures and higher energy efficiency. Due to the relatively constant temperature of groundwater, it can provide lower cooling temperature during summer cooling; During winter heating, it can provide a higher heating temperature.
