摘要
介绍一套以太阳能液体除湿制冷为主,太阳能喷射制冷为辅的全新风空调系统,描述系统原理及流程;建立液体除湿-喷射冷却的空调实验装置;分析比较喷射制冷应用于除湿制冷中不同部位的性能及可行性;在兼顾系统效率的同时解决送风温度偏高问题;针对上海地区的气候特点,对该系统做了实验研究,在热源温度为75℃时,送风温度为19℃时,总系统COP可达0.7。
Introduces a fresh air handling unit which uses solar-liquid desiccant for dehumidification, assisted by a solar ejector refrigeration device. Describes the principle and the flow of system. Establishes experimental setup for liquid desiccant dehumidification-ejector refrigeration. Compares the different efficiency and feasibility of the air conditioning system when the ejector refrigeration device is used in different places of the unit. The simulated calculation of COP shows that the system operated efficiently and that supply air temperature does drop down. After studying the probability of the air conditioning system during the summertime in Shanghai, draws the conclusion that the system＇ s COP could reach 0.7 with supply air temperature at 19 ℃ when the heat source temperature is just about 75 ℃.
