摘要文章提出一种热泵热水器全年综合能效(ACE)的方案,并对影响热泵热水器全年综合能效
(ACE)的因素进行了分析。该方案将热泵热水器全年运行工况分为高、中、低三个区间,计算得出
各个温度区间在全年范围中的比重,以及各个温度区间的平均发生温度,将计算出的平均温度作为
测试工况,测试系统 COP,最后经过加权计算,得出热泵热水器全年综合能效(ACE)。对该方案进
行的实验验证证明,全年综合能效(ACE)能够考虑环境温度对机组性能的影响,即能反映了热泵
热水器夏季时的高效率,也能反映了冬季时机组性能受影响较大的情况。

Abstract Annual consolidated energy efficiency (ACE) program made in this paper, and the factors that
would affect the annual consolidated energy efficiency were analyzed. The running conditions of HPWH
were divided into high, medium and low ranges through the year accord to this program, the proportion of
each temperature range and the average temperature of each range were calculated respectively throughout
a year time, the COP of system was tested according to the average temperature, and the value of the ACE
would get by means of weighted. The experimental study verified that ACE program could reflect the
impact of the environmental temperature on the unit performance. The high efficiency in summer and low
in winter
