摘要
对一台以R417A为工质的热泵型房间空调换热器在不同室外干、湿球温度工况下的温度分布情况进行了试验研究和分析。通过对管翅式换热器温度分布规律的研究,找出其换热特性,在对试验结果进行综合分析的基础上,提出了优化设计建议。
It was investigated the condition of temperature distribution of heat pump room air conditioning heat exchanger in dif- ferent outdoor dry,web- bulb temperature , R417A is used as working substance , under the condition, the experiment research and analysis was carried on. Based on the study of temperature distribution regularity of tube - and - fin type heat exchanger, and find out the heat transfer characteristics, based on the analysis of the experimental results, the optirhization design is put forward as a suggestion
