By using little amount of high-grade energy

the water source heat pump realizes converting low temperature heat energy to high temperature heat energy

which has good energy saving effect.The water temperature and quantity of water side and user side has a great effect on the heating performance of the heat pump.To make the maximum conversion of low temperature heat energy to high temperature heat energy

the factors affecting the heating performance of water source heat pump were experimentally investigated under heating conditions.The results show that countermeasures like increasing the inlet water temperature at water side

reducing the outlet water temperature at user side and increasing the water flow at both sides can improve the heating system performance

which provides a reference for high performance and application of water source heat pumps.
