摘要
介绍了基于温度频段法的制热季节性能系数(HSPF)方法。考虑地表水地源热泵系统水源温度的特点,对HSPF法进行简化,以逐日地表水水温和室外空气温度代替逐时温度,评估地表水地源热泵系统的供暖节能性。采用费用年值法计算地表水地源热泵系统供暖的投资费用。以某地表水地源热泵工程为例,计算了系统能耗和单位建筑面积的供暖季费用年值,并与空气源系统能耗进行比较。结果表明,在夏热冬冷地区采用地表水地源热泵比空气源热泵节能31.5%,单位建筑面积供暖费用年值可节约3.3元/(m2·a)。
Presents the heating seasonal performance factor （HSPF）method based on the temperature frequency method.Considering the characteristics of surface water temperature of this heat pump, simplifies the HSPF method by a calculation with daily average water temperatures and outdoor air temperatures instead of hourly temperatures to evaluate the energy saving performance of the surface water source heat pump.Calculates the heating cost of heat pump system by the annual cost method.With a heat pump project as an example,calculates the energy consumption and heating cost per unit building area,and compares with those of air-source heat pump.The results show that the surface water heat pump can reduce energy consumption by 31.5% and annual cost per unit building area by 3.3 yuan/（m2 ·a）in hot summer and cold winter zone.
