摘要：

This paper established a heat pump system model containing heat pump unit model, AC load model and heat exchanger model utilizing the mass and energy balance and the structure's designing method. This paper also developed the surface water source heat pump air conditioning system simulation program by Visual Basic, and verified the simulation by the actual engineering project. In addition, this paper explored the impact of the surface water temperature and heat exchanger structure on the heat pump air conditioning system operation. The results shows that one degree drop of the surface water temperature leads to 2.3 per cent increase of performance coefficient and a 100m added length of the closed-loop surface water heat exchanger tube leads to 0.08 per cent increase of performance coefficient.
