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。
By measuring the winter water temperature in Huaihua, Xiangtan and Huangshi areas and combining with the outdoor meteorological data of the current month and the influencing factors of many water temperatures, a simple and easy method of predicting the winter water temperature in Hunan Province was proposed. The influencing factors of water surface temperature are pointed out by taking the surface temperature of water as parameter, including the coefficient a which can reflect the comprehensive heat exchange between water body and environment. The method of water temperature prediction is compared with the relevant literature to show its rationality . Considering the need of water source heat pump system design, the concept of water source heat pump system design winter reference water temperature is proposed. Through the relationship between water temperature and air temperature, the reference water temperature of winter design can be found and the reference value of typical area of Hunan is given.
