Solar air conditioning researches and demonstrations in China

This paper mainly shows the demonstration of solar air conditioning systems in China, which includes LiBr-H2O absorption cooling, silica gel-water adsorption chiller, desiccant cooling and hybrid integrated energy systems for buildings. The match of solar collector types and chiller types have been discussed and suggested.

氮气储粮气囊内控温工艺研究

在氮气储粮期间,采用氮气密闭循环制冷设备,通过密闭保温管道,将密闭粮堆上层及气囊内高温氮气抽出进行制冷调湿后再输送至密闭粮堆进行循环制冷,控制密闭粮堆上层及气囊内的氮气温湿度,进而抑制粮温,实现充氮气调期间的低温准低温储藏。
