Abstract
A motor vehicle chiller with several evaporators of different cooling capacity, has a refrigerant circulation with at least one refrigerant compressor, at least one condenser, at least one expansion element as well as at least two evaporators disposed in parallel of different cooling capacity. A refrigerant collector is disposed downstream of the expansion element and upstream of the evaporator of lesser cooling capacity to separate liquid refrigerant. Between the refrigerant collector and the evaporator a refrigerant pump is disposed to convey the liquid refrigerant to the evaporator of lesser cooling capacity. The refrigerant vapor can be guided from the evaporator across the refrigerant collector functioning as a separator and be drawn in by the refrigerant compressor.
