本文介绍了在实际使用条件下对集成系统的热水性能进行的现场测试结果。在两年的时间里，在24个居民点进行了实地测试。为了测量水的加热效率，在夏季的几个月里，对专门使用热水的时段进行了水加热数据采集。集成系统与现有的传统热水器并排安装，每周交替监测性能。数据分析表明，在64.3加仑/天（243.4升/天）的使用量下，非冷凝集成系统以49-54%的效率生产热水，这与传统热水器的性能相当。冷凝集成系统的相应效率为58%，与能源系统的性能相当- 节约热水器。引文:ASHRAE Transactions，1983年，第89卷，pt。新泽西州大西洋城1B号

This paper presents field test results on the water-heating performance of integrated systems under actual usage conditions. Field tests were performed at 24 residential sites over a two-year period. Water-heating data were taken for periods of exclusive hot water usage during the summer months in order to measure the water-heating efficiency. The integrated systems were installed side by side with the existing conventional water heaters, and performance was monitored for alternating weekly periods. Analysis of the data indicates that the noncondensing integrated systems produce hot water at an efficiency in the 49-54% range at 64.3 gal/day (243.4 L/day) usage, which is comparable to the performance of conventional water heaters. The corresponding efficiency of the condensing integrated system was 58%, which is comparable to the performance of energy-conserving water heaters.
