摘要
设计了一种能较为准确地计算空气源热泵热水机组全年能效比(COP)的方法。过往的研究仅考虑到了全年各时段环境温度和水温,而此方法还考虑了用水规律对COP的影响。用水规律主要包括以下两点:第一,考虑不同季节热水用水量的不同对季节、全年COP的影响;第二,考虑了每日不同时段的用水规律对每日、全年COP的影响。结合某典型二级能效的空气源热泵热水机组的性能参数,以及浙江省全年气象数据,根据研究确定的计算方法,计算空气源热泵热水机组在浙江省气候环境下应用的全年和各季节的COP。
This paper designs a more accurate method to calculate the annual coefficient of rerformance(COP)of air source heat pump hot water system.Previous studies only considered the ambient temperature and water temperature of each period of the year,while this method also considered the impact of water use laws on COP.The law of water use mainly includes the following two points:First,consider the impact of different hot water consumption in different seasons on seasonal and annual COP.Second,the impact of water use rules at different times of the day on daily and annual COP is considered.Based on the performance parameters of a typical two-stage energy efficiency air source heat pump hot water unit and the annual meteorological data of Zhejiang province,the annual and seasonal COP of the air source heat pump hot water unit applied in the climatic environment of Zhejiang province is calculated according to the calculation method determined by the research.
