Abstract: A method for operating a temperature-control device having a compressor line flowing a total mass flow of refrigerant and having a refrigerant compressor by which the refrigerant is conveyed and compressed, a condenser line branches off from the compressor line and flowing a first partial mass flow of the refrigerant, and having a first expansion valve to set and expand the first partial mass flow, and a condenser to condense the first partial mass flow arranged in the condenser line upstream of the first expansion valve. The refrigerant circuit includes a bypass line which is connected parallel to the condenser line and which branches off from the compressor line and through which a second partial mass flow of the refrigerant thus flows.

Abstract: A refrigeration circuit for a motor vehicle includes a refrigerant compressor, a condenser for exchanging heat with a cooling circuit, a chiller for exchanging heat with the cooling circuit, and an evaporator for temperature control of air in an air-conditioning device. The evaporator being in parallel with the chiller, and, in a main circuit, the refrigerant compressor, the condenser, and the parallel circuit of chiller and evaporator being connected in series. The circuit also includes a return line that branches off from the main circuit on a high-pressure side of the refrigerant compressor and leads into the main circuit on a low-pressure side of the refrigerant compressor, and a valve circuit to block and release flow through the return line.
