本文介绍了一所学校的现场监测数据，该学校安装了一台热泵热水器（HPWH）和一个蓄水池，用于预热具有多个再循环回路的燃气热水系统的水。结果证明了HPWH预热在学校高用水区域的有效性，并证实了再循环回路系统的高热损失。作者讨论了这项工作的意义，因为它涉及到学校工业用水供暖系统的总体设计策略。 单位:双引文:研讨会，ASHRAE交易，第110卷，pt。2.

This paper presents field-monitored performance data from a school where a heat pump water heater (HPWH) was installed with a storage tank to preheat water for a gas-fired hot water system with multiple recirculation loops. The results demonstrated the effectiveness of HPWH preheating for high water use areas in the school and confirmed the high thermal losses from the recirculation loop system. The authors discuss the implications of this work as it relates to the overall design strategy for service water heating systems in schools.Units: Dual
