采用定速压缩机的低环境温度空气源热泵(冷水)机组季节能效评价分析及试验研究

Seasonal energy efficiency evaluation analysis and experimental study on low ambient temperature air source heat pump(water chilling)packages with fixed speed compressor

产品标准GB/T 25127.1—2020《低环境温度空气源热泵(冷水)机组第1部分:工业或商业用及类似用途的热泵(冷水)机组》于2021年4月1日实施,对该类产品的性能评价方法由综合部分负荷性能系数(IPLV)转变为季节能效(HSPF及SEER)评价。如何适应新版标准的评价方法,本文从季节能效评价的基本思路进行理论分析,对季节能效试验的主要优化方向进行研究,并通过试验进行验证。结果表明,改进后的测试策略使机组HSPF及SEER分别提升4.9%和3.3%。

GB/T 25127.1-2020 Low ambient temperature air source heat pump(water chilling)packages-Part 1:Heat pump(water chilling)packages for industrial&commercial and similar application is implemented from April 1,2021,the method of performance evaluation is transformed from integrated part load value(IPLV)to seasonal energy efficiency such as HSPF and SEER.How to adapt to the evaluation method of new version standard,based on the theoretical analysis on the basic ideas of seasonal energy efficiency evaluation,the main optimization directions for the seasonal energy efficiency tests are researched,which are verified by experiment.The results show that HSPF and SEER are increased by 4.9%and 3.3%respectively with application of improved test strategies.
