摘要

为解决热泵与电热水器能效评价指标不统一的问题，本研究提出了一种基于24小时动态用水试验的统一能效评价方法。通过分析我国居民热水使用习惯，建立了包含用水时间分布、温度需求和流量特征的典型用水模式，并设计了基于一次能源利用效率的统一评价指标。实验验证表明，热泵热水器一次能源效率（67.7%~99.2%）显著高于储水式电热水器（31.5%~36.4%），该方法能有效实现横向比较。

Abstract

In response to the problem of inconsistent energy efficiency evaluation indicators between air source heat pumps and storage type electric water heaters in China

this study proposes a unified energy efficiency evaluation method based on 24-hour dynamic water use tests. By analyzing the hot water usage habits of Chinese residents

a typical water usage pattern was established that includes water usage time distribution

temperature demand

and flow characteristics. A unified evaluation index based on primary energy utilization efficiency was also designed. Experimental verification shows that the primary energy efficiency of heat pump water heaters (67.7%~99.2%) is significantly higher than that of storage electric water heaters (31.5%~36.4%).
