多联式空调热泵机组标准研究

Research on the Standards of Multi-spilt Air-conditioning and Heat Pump Unit

本文分析了多联式空调热泵机组各地区标准的运用情况,围绕产品范围、实验要求、工况条件和判定要求等方面对各标准的差异性进行讨论,通过对比各标准中能效评价指标,对多联机采用的能效评价指标的合理性进行探讨。结果表明:空气源多联机系统推荐采用全年性能系数(Annual Performance Factor,APF)评价指标,水源多联机系统推荐采用制冷综合部分负荷性能系数(Cooling Integrated Part Load Value,IPLV)评价指标;为多联机全球标准的编制以及工况条件、计算方法、测试方法和评价指标的制定奠定了理论基础和依据,旨在推进多联机全球化标准统一进程,促进多联机相关技术的升级换代和产品的贸易流通,为多联机产品的研发提供参考。

The application of various regional standards of multi-spilt air-conditioning heat pump units is analyzed in this paper.The differences of various regional standards on product scope,test requirement,test condition and judgement requirement are discussed.By comparing energy efficiency evaluation index,the rationality of energy efficiency evaluation index for variable refrigerant flow(VRF)is also discussed in the paper.The results show that,it is recommended to adopt the annual performance factor(APF)evaluation indexes for air-source VRF system,and the cooling integrated part load value(IPLV)evaluation indexes for water source VRF system.It lays a theoretical foundation and basis for the establishment of global standards,including conditions,calculation methods,test methods and evaluation indexes,which aims to promote the process of unifying the global VRF standard,to upgrade new technology,to trade circulation of products,and to provide reference for product research and development.
