摘要
自产品标准GB/T 18837—2015《多联式空调(热泵)机组》于2016年7月1日实施以来,笔者所在单位已开展600余套此类产品能效试验,检验样品覆盖国内主流品牌的市场流通产品,检验样品室内外机组合型式在满足产品标准基本规定的前提下也具有多样性。本文基于检验数据及检验过程中面临的具体问题,对风冷多联式空调(热泵)机组产品的市场能效水平进行了分析,并针对GB 21454—2021能效标准中的能效限定值及能源效率等级给出了验证结果。
Since the implementation of GB/T 18837-2015 Multi-connected air-conditioning(heat pump) unit on July 1, 2016, the authors’ company has carried out energy efficiency level inspection tests of such units for over 600 times. The trial samples cover the products of the major brands circulating in domestic market. Fulfilling the requests of the national standard, the combinations of trial samples manifest great diversity. Based on the inspection data and the practical problems met during tests, a thoroughly analysis is conducted, aiming at revealing the energy efficiency level of air-cooled units circulating in domestic market and providing verification for the energy efficiency limit values and grades regulated by the standard GB 21454-2021.
