DUAL TYPE SYSTEM FOR REFRIGERANT COLLECTION AND DUAL TYPE APPARATUS FOR REFRIGERANT COLLECTION USE FOR THE SAME

摘要

PURPOSE: A dual type refrigerant recovering system and a dual type refrigerant recovering utilized for the same are provided to simultaneously liquidize refrigerants by respectively recovering the same from two kinds of refrigerant recovering objects and obtain the compact dual type refrigerant recovering device by separating a storage tank for storing the liquidized refrigerants. CONSTITUTION: A dual type refrigerant recovering system(10) comprises a dual type refrigerant recovering device(100) and external storage tanks. The dual type refrigerant recovering device includes a first refrigerant recovering tank(110), a first compressor(120), a first cooling cycle device(130), a second refrigerant recovering tank(210), a second compressor(220), and a second cooling cycle device(230). The first refrigerant recovering tank recovers a refrigerant along a first refrigerant recovering passage providing a moving passage from a first refrigerant recovering object connected to a first refrigerant recovering port. The first compressor is arranged in the first refrigerant recovering passage, thereby providing pressure required for recovering the refrigerant. The first cooling cycle device is connected to the first refrigerant recovering tank and liquidizes the refrigerant flown into the first refrigerant recovering tank, thereby discharging the refrigerant through the first refrigerant discharging port. The second refrigerant recovering tank recovers a refrigerant along a second refrigerant recovering passage providing a moving passage from a second refrigerant recovering object connected to a second refrigerant recovering port. The second compressor is arranged in the second refrigerant recovering passage, thereby providing pressure required for recovering the refrigerant. The second cooling cycle device is connected to the second refrigerant recovering tank and liquidizes the refrigerant flown into the second refrigerant recovering tank, thereby discharging the refrigerant through the second refrigerant discharging port.
