【摘要】 低环境温度空气源热泵机组产品已逐渐成为我国北方寒冷地区重要的供热设备,迫切需要为其建立一套科学合理的国家标准。本文针对标准中的制热综合部分负荷性能系数IPLV(H)评价方法,从IPLV(H)计算公式权重系数的确定、部分负荷率测试工况点的选取及制热性能系数COP_h的测试方法三个方面进行研究,提出具体建议方案,为商用和户用低环境温度空气源热泵(冷水)机组的标准制定提供参考。更多还原

【Abstract】 Low environment temperature air source heat pump packages are becoming important heating services in the cold area of North China;therefore it is necessary to establish a reasonable national standard for the industry.In this paper,the evaluation of heating integrated part load value(IPLV(H))is researched from three aspects:the calculation of weight coefficients in the e- quation,the test condition of the part load ratio,and the test method of heatingCOP(COP_h)in each load ratio.Discussions and suggestions are brought forward as references for the establishing standard on low environment temperature air source heat pumps for commercial and residential application.更多还原
