Coolant circuit arrangement with ejector pump coolant has adjustable output of first and second compressors, reduction in coolant pressure through nozzle and decompression device

摘要

The arrangement has first and second compressors (11,21) for sucking in and compressing coolant, first and second coolers (12,22), an ejector pump (13), a first evaporator (14), a decompression unit for decompressing and expanding coolant flowing out of the second cooler and a second evaporator (24) for decompressed coolant. The coolant output of the first and second compressors and the reduction in coolant pressure through a nozzle and the decompression device can be adjusted.
