摘要

The refrigerant circuit (K) has a compressor (1) for the compression and conveyance of a gaseous refrigerant, heat exchangers (2,5), particularly a refrigerant condenser or evaporator. An air regulating device (4) is for the relaxation of the refrigerant, and has two bypasses with two valves (4.2,4.3). Contactors admitted with refrigerant are assigned to the valves, where the valve (4.2) opens with exceed of an upper pressure threshold value available in the refrigerant and the later valve (4.3) opens when falling below a lower pressure threshold value.
