Abstract: A pressure relief arrangement in refrigerant circuits with one high-pressure side and one low-pressure side, which is characterized in that the high-pressure side is fluidically connected with the low-pressure side of the refrigerant circuit via an overpressure relief device, wherein the overpressure relief device causes pressure reduction of the overpressure in the case of overpressure on the high-pressure side and fluid flows from the high-pressure side to the low-pressure side of the refrigerant circuit.

Abstract: A method for operating an air-conditioning system of a motor vehicle, wherein the air-conditioning system comprises a refrigerant circulation and a water circulation which are thermally coupled with one another across a condenser/gas cooler. Water circulation flows through the condenser/gas cooler at a low volumetric rate of flow and a high temperature difference so the water circulation transfers heat in the heating heat exchanger to the air in a similar temperature range. Refrigerant circulation cools from 65° C. to 70° C. to −10° C. to +30° C. and water circulation raises to a temperature of 55° C. to 65° C. and that an adaptation of the temperature profile of the water circulation to the temperature profile of the refrigerant circulation takes place in the condenser/gas cooler utilizing a temperature glide of the refrigerant. The refrigerant is significantly cooled.

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.

Abstract: An apparatus for separating and storing liquid refrigerant in a refrigerant circuit including a housing configured as a refrigerant collection container, the housing having a refrigerant outflow line disposed therein. The refrigerant outflow line extending from an inlet opening, which is disposed in a gas refrigerant region and above a level of the liquid refrigerant, via a liquid refrigerant region to the outside, and has a through-opening formed in the liquid refrigerant region. The housing includes a boiling element for liquid refrigerant disposed therein. The boiling element is connected to the refrigerant outflow line in the region of the through-opening, such that a liquid passing through the through-opening from the housing passes through the boiling element by suction of a gas refrigerant.

Abstract: A device for heat distribution in a hybrid motor vehicle includes an engine cooling circuit and a refrigerant circuit for a combined operation in a refrigeration heat pump mode and a reheating mode. The refrigerant circuit includes an evaporator, a compressor, a heat exchanger to supply heat from the refrigerant to air being conditioned for a passenger compartment, and a heat exchanger to transfer heat between a refrigerant of the refrigerant circuit and coolant of the engine cooling circuit. The heat exchanger operates as an evaporator for the heat transfer from the coolant to the evaporating refrigerant, and alternatively operates as a condenser for the heat transfer from the condensing refrigerant to the coolant.
