摘要

采用季节性能评价指标体系是多联式空调（热泵）机组（以下简称：多联机）性能评价的发展方向。针对在季节性能评价指标体系下多联机制热性能实验中存在的问题，分析现行国内外相关标准对非稳态制热性能实验方法的优缺点，指出欧洲及ISO标准规定的非稳态制热性能实验方法更能客观地反映多联机的制热性能，而且可操作性强，可重复性好；同时分析采用欧洲及ISO标准规定的非稳态制热性能式验方法对我国多联机性能评价可能带来的影响，进而提出我国多联机非稳态制热性能实验方法的总体框架和尚需解决的问题。

Abstract

Seasonal performance evaluation index is taken as the direction to evaluate multi-split air-condition (heat pump) units (Hereinafter referred to as: VRF) in the future. The challenge on unstable heating performance test for VRF unit is discussed when seasonal performance evaluation index is used. Advantages and disadvantages of unstable heating performance test methods in relevant standards are analyzed. The conclusion indicates that the unstable heating performance test methods in EN and ISO standards reflect the heating performance of VRF units more objectively

and are with good operability and repeatability. Potential effect of the unstable heating performance test method in EN and ISO standards on the development of VRF in China is investigated. The outline and issues of Chinese unstable heating performance test method for VRF units are suggested.
