摘要

This paper presents technical approach on cooler air conditioner based on thermal conver-sion of solar radiation technology,i.e.transforming solar energy to heat energy,and use the heat energy to achieve refrigeration.We developed a new solar absorption air conditioning system based on the thermal conversion of solar radiation technology.Through verification studies,the operating characteristics of so-lar collector and heat storage system of air conditioning systems,and operating characteristics of the re-frigeration unit are verified.The experiment shows:the air conditioning system can operate continuously and stably for 8 hours.The average cooling capacity is 4 kW,and the maximum cooling capacity is 4.7 kW.The system COP average is 0.3.Therefore,this new solar absorption air conditioning system based on thermal conversion of solar radiation technology provides a feasible method to realize large scale,low cost application of solar energy.%给出了以太阳能辐射技术为基础的热能转换空调制冷技术的技术方法,即将太阳能转变成热能,使用热能进行制冷。以太阳能辐射技术的热能转换为基础,研制了新型的太阳能吸收式空调系统,并且通过实验研究,验证了该系统的集热、蓄热特性以及制冷机组的运行热性。实验表明,该空调系统可连续8 h 稳定地工作,最大制冷量可达到4.7 kW,平均值也可达到4 kW,该空调系统性能参数 COP,平均可达到0.3。因此,基于太阳能辐射技术的热能转换空调制冷技术为太阳能规模化、低成本应用提供了行之有效的新方法。
