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。Annual consolidated energy efficiency(ACE) program was proposed in this paper,and the factors that would affect the annual consolidated energy efficiency were analyzed.The running conditions of HPWH in one year were divided into high,medium and low ranges according to this program,the proportion of each temperature range and the average temperature of each range were calculated respectively throughout one year time,the COP of system was tested according to the average temperature,and the value of the ACE was calculated 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 running condition and low efficiency in winter running condition were both reflected in this program.
