摘要
本文叙述一台带有室外热交换器的变速CO_2热泵热水器的实验室测定结果。测试包括在室外环境温度为-8.3℃至35℃下进行的标准24小时和第1小时的额定等级试验的热泵效率;室外机的噪声水平测定;和对输送水量测定以及室外机组在10℃环境条件下运行时的高效率淋浴水量测定。
This paper describes the results of a CO_2 Heat pump water heaters test with an outdoor heat exchanger. The project conducted lab tests of a variable- speed,CO2 refrigerant HPWH with the heat exchanger located in the outdoor unit. The testing plan included observing heat pump efficiency at a range of outdoor ambient temperatures from- 8. 3℃ to 35℃; conducting the standard 24- hour and 1- hour rating tests; measuring outdoor unit noise levels; and quantifying the number of efficient showers delivered with the outdoor unit operating at 10℃ ambient conditions.
