Working Principle:

The high-power centrifugal water source heat pump unit operates by utilizing water sources such as rivers, lakes, or underground water. In heating mode, it extracts heat from the water source via a centrifugal compressor and refrigerant cycle, transferring the heat to provide warmth. In cooling mode, it absorbs heat from indoor spaces and releases it into the water source. The unit’s high power enables it to handle large heating and cooling loads for applications like commercial buildings, industrial facilities, district heating and cooling systems, data centers, residential complexes, and sports and recreational facilities. Its advanced compressor technology offers reliable operation and high efficiency, while being environmentally friendly by reducing reliance on fossil fuels and lowering greenhouse gas emissions. The basic steps include:

Heat Absorption:

Waste heat is absorbed by the refrigerant in the evaporator.

Compression:

The refrigerant is compressed in the compressor, raising its temperature and pressure.

Heat Release:

The heated refrigerant transfers its energy in the condenser to a secondary medium (such as water or air) for space heating, industrial processes, or hot water supply.
