摘　　要：通过对怀化、湘潭及黄石地区的冬季水温进行实测,结合当月室外气象资料及诸多水温影响因素,提出了一种可以预测湖南地区冬季水温的简易方法。以水体表面温度为参数,指出了水体表面温度的影响因素,包括可反映水体与环境之间综合热交换特性的系数a;并将该水温预测方法与相关文献进行对比,表明了它的合理性。考虑到水源热泵系统应用设计的需要,提出了水源热泵系统设计冬季参考水温的概念,通过水温和气温之间的变化关系,可找到冬季设计参考水温,并给出湖南典型地区的参考值。A simplified predicting method of surface water temperature in winter of Hunan district was established based on the water temperature measured and outdoor air temperature observed,many influence factors of surface water temperature in winter of Huaihua,Xiangtan and Huangshi in this paper. And the influence factors of surface water temperature were analyzed,including the comprehensive heat transfer characteristic between water and surrounded environment which was thought to be reflected by parameter a in the predicting model. The results were proved to be reasonable by comparing with the related research results. In addition,considering the need for surface water source heat pump system,a new designed concept,namely designed reference water temperature in winter was proposed for water source heat pump system. The designed reference water temperature could be obtained based on the relationship between water temperature and air temperature,and a reference value for typical areas in Hunan was proposed.
