一、概述我国低温冷藏库的制冷设备大都采用排管,生产运行后,由于热湿交换的结果,空气中的水份便在排管上凝结成霜,积霜后便增加了排管传热的热阻,使传热系数降低,制冷量减少,电耗增大。因此,应该及时地清除排管上的霜层,以提高传热效果,减少能耗,这是冷库生产管理中的 First, an overview of China’s low-temperature cold storage refrigeration equipment used mostly pipes, production runs, due to the results of heat and moisture exchange, the water in the air pipe will condense into a frost, the accumulation of frost will increase the heat pipe The thermal resistance, so that the heat transfer coefficient decreases, the cooling capacity to reduce power consumption increases. Therefore, the timely removal of the frost on the pipe to improve heat transfer and reduce energy consumption, which is cold storage production management
