报告了配备热管换热器（HPHX）的超市空调系统的六项现场研究的发现和见解。现场测试检查了在四种不同气候条件下运行的不同仓库和供暖、通风和空调（HVAC）系统设计。测试了两种基本的HVAC配置——单路和双路。每个站点都配备了良好的仪器，包括一个带有远程数据检索的现场数据采集系统。研究发现，通过降低超市的室内湿度，可以实现制冷能源的大幅节约。迄今为止的结果表明，在50华氏度（10摄氏度）的露点范围内，每降低一华氏度（1.4%/天/摄氏度）的室内露点，平均制冷节能0.65%。而在室内露水较低时，暖通空调能耗和需求增加- 研究发现，点控制、设置、热负荷的现场变化与室内露点设定值一样影响能耗和需求。由于确定量级和源冷负荷分量的复杂性，无法就应用HPHX和降低室内露点的净效益得出任何一般性结论。关键词:性能、超市、空调、测试、热交换器、湿度、制冷、能耗、节能、露点、热负荷、冷负荷、美国、空间制冷、建筑、除湿、热管、水分、冷凝。引文:研讨会，ASHRAE交易1993，第99卷，pt。1.

Reports findings and insights from six field studies of supermarket air conditioning systems equipped with heat pipe heat exchangers (HPHX). The field tests examined different store and heating, ventilating, and air conditioning (HVAC) system design operating in four different climates. Two basic HVAC configurations were tested - single-path and dual-path. Each site was well-instrumented and included an on-site data acquisition system with remote data retrieval. Substantial savings in refrigeration energy were found to be achievable with a reduction of indoor humidity in supermarkets. Results thus far indicate a mean refrigeration energy saving of 0.65% per degree Fahrenheit (1.4%/day/deg C) of indoor dew-point reduction (in the range of 50 deg F (10 deg C) dew point. While HVAC energy consumption and demand increased at the lower indoor dew-point control, settings, site-to-site variations in thermal loads were found to affect energy consumption and demand as much as indoor dew-point setpoint. The complexities of determining the magnitude and source cooling load components prevented the drawing of any general conclusions on the net benefits of the application of HPHXs and reduced indoor dew point.KEYWORDS: performance, supermarkets, air conditioning, testing, heat exchangers, humidity, refrigeration, energy consumption, energy conservation, dew point, heat load, cooling load, USA, space cooling, buildings, dehumidifying, heat pipes, moisture, condensation.
