欧盟空调性能标准2018版的主要变化及对冷水机组性能计算的影响

European ecodesign standards revision in 2018 and its influence on performance calculation of water chilling packages

欧盟自2021年1月起,对空调产品季节制冷能效比实施第二阶段的要求,相关计算和测试方法需要按照EN14511及EN14825的2018版执行。本文总结这2个标准中针对冷水机组产品的修订内容,分析修订内容对冷水机组能效的影响,为产品的改进和研发提供设计参考。

Since January2021,the Tier 2 requirements of seasonal energy efficiency ratio for air-conditioning products have come into force in Europe.The calculation and test methods should be based on EN14511-2018 and EN14825-2018.The main revisions for water chilling packages products in these two standards are summarized,and the influence on the energy efficiency of water chilling packages are analyzed,which provide design references for the improvement and research&development of water chilling packages products.
