蓄冷型太阳能喷射制冷系统设计分析

Study of Energy-storage Solar Ejector Refrigeration System

介绍了蓄冷型太阳能喷射制冷系统的工作原理,确定了蓄冷量的设计原则。基于郑州地区一栋200m2的住宅建筑,计算了制冷系统逐时制冷量和空调逐时冷负荷,并进行了蓄冷量的设计。研究表明,当太阳能集热面积为20m2时,该太阳能喷射系统的日设计蓄冷量为21.6kJ;与常规喷射制冷系统相比,年制冷量可提高20%左右。

The operating principle of energy storage solar ejector refrigeration system was introduced, and the design principle of cold storage capacity was developed. Based on the 200 m2 residential construction in Zhengzhou region, the hourly cooling capacity, hourly cooling load and cold storage capacity were calculated. The research showed that the cold storage capacity of solar ejector refrigeration system equals to 21.6 kJ when the solar collector area is 20 m2 , it is determined that the cooling capacity of energy storage solar ejector refrig- eration system can be improved about 20% compared with conventional system.
