目前欧盟热泵热水器测试标准 EN 16147：2011，Heat pumps with electrically driven compressors- Testing and requirements for marking of domestic hot water units已于2011年7月开始实施，但国内的标准GB/T 23137-2008并未有相应的更改。本文将通过测试静态加热式热泵热水器来对比分析其能效测试结果相对于国标测试方法的不同，并分析出目前国内开发的主流的热泵热水器在售后使用时的真正能效是否节能，并考虑到售后使用的能效情况，提出设计热泵热水器时的优化节能方向和售后客户使用的节能注意事项。%The European standard, EN 16147:2011,Heat pumps with electrically driven compressors - Testing and requirements for marking of domestic hot water units, has been put into effect from July, 2011. However, Chinese na-tional standard is still the GB/T 23137-2008 which hasn’t made the corresponding changes. In this paper, it tests the static heating water heat pump and use its data to compare and analyze the differences of Chinese national standard and European standard, including the coefficient of performance which used by users. Furthermore, this paper points out the development direction of energy conservation of heat-pump water heater and the matters needing attention for us-ers in consideration of the coefficient of performance.
