摘要
提出了一种简单易行的地表水源热泵空调系统供暖能耗评价方法,即采用逐日累加法计算系统制热季节性能系数(HSPF),文中详细介绍了该方法的计算步骤。利用夏热冬冷地区某地表水源热泵工程作为算例,采用逐日累加法进行了系统的供暖能耗评价,HSPF达最大值时的供暖模式即为最优供暖模式,据此可对冬季热泵机组运行台数和辅助加热进行最优调节。分析了机组热水出水温度、室内设定温度、气象条件对HSPF值及供暖耗电量的影响。这种方法对地表水源热泵空调系统的设计具有一定的指导意义,避免了选择机组的盲目性。
In order to determine the optimal heating parameters of a surface water heat pump （SWHP） system, a new simplified procedure to calculate the Heating Seasonal Performance Factor （HSPF） of SWHP systems was proposed in this paper, which was the daily accumulation calculating method. Taking a SWHP project in hot summer and cold winter zone as an example, the energy consumption of SWHP was investigated in this paper. The heating model will be the optimal model when the HSPF reaches the maximum which can suggest the optimal parameters of the SWHP system. Moreover, the influence of the hot water temperature from the units, indoor setting temperature and meteorological conditions on the HSPF and the total energy consumption for heating was analyzed. This method can apply design suggestions for designers avoiding the blindness for choosing SWHP units.
