水源多联式空调机组性能评价方法探讨

分析现行国家标准中3种对于可变流量空调性能评价值SEER和IPLV测试方法的适用范围和运行工况的特点,结合水源多联机系统特点和部分负荷测试方法,探讨其性能测试方法和评价值,同时采用按照国家标准规定环境参数特点和使用场所建筑物特性的权重系数,提出可连续卸载运行机组的试验方法和计算公式,对于不可连续卸载运行的机组提出通过开-停试验进行测试的方法及其试验方法和计算公式。按照有关国家标准的规定,针对检测装置提出一些特殊要求,对于冷却侧,按室外水侧量热计法进行校核计算。对于具有热泵功能的水源多联机组,提出考核条件和今后研究的方向。

Discussion on performance evaluation methods of water-source multi-connected air-conditioning unit

The scope of application and the characteristics oI operating conamons of three evaluation methods in existing national standards are analyzed which are used for calculating the performance evaluation, SEER and IPLV, of the variable flow air-conditioning. Combined with the features and the part-load testing method of the water-source multi-connection unit system, the performance testing methods and the performance evaluation are discussed. Moreover, by using environmental parameters features in accordance with the provisions of the national standard and weight coefficients of the building features, test methods and formulas of the continuous unloading operation unit are brought forward. For the non-continuous unloading operation unit, the start-stop testing method is put forward, and the testing methods and formulas are provided. In accordance with the provisions of national standards, some special requirements are provided for the testing equipment, the check calculation for the cooling side is done with outdoor-water-side meas urement. The evaluation condition and further research direction are provided for watersource multi-connected air-conditioning unit with heat pump function.
