摘要

水源热泵利用少量高品位能源实现低温热能向高温热能的转移

具有较好的节能效果。水源热泵水源侧和用户侧的进水温度、水流量对其制热性能有较大的影响。为了使低温热能最大化的转化为高温热能

在制热工况下通过试验对影响水源热泵制热性能的因素进行研究

得出通过提高水源侧进水温度、降低用户侧进水温度、增大两侧水流量来提高系统的制热性能

为水源热泵的高性能运行和应用提供参考。

Abstract

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.
