An evaporator heat exchanger unit for a heating cooling module for a motor vehicle is disclosed. In one aspect, the evaporator heat exchanger unit includes at least one collector expansion tank for collecting a refrigerant and one evaporator, by which at least a part of the refrigerant can be converted into gaseous form. The evaporator heat exchanger unit also includes a housing enclosing an inner chamber, wherein in the inner chamber, the collector expansion tank, the evaporator, and a cooling medium are arranged, and wherein an expansion organ is arranged on the housing, by which the refrigerant is supplied to the evaporator.

Evaporator heat exchanger unit

The invention relates to a compressor-heat exchanger unit for a heating-cooling module for a motor vehicle, in which at least one fluid serving as a coolant flows, comprising a compressor device for compressing the first fluid, at least one heat exchanger device that has at least one first circuit for the first fluid to flow through and a second circuit for a second fluid to flow through, this heat exchanger unit being arranged in the fluid stream after the compressor device, characterized in that the first fluid is guided at least partially in flow channels of the first circuit that at least partially enclose the compressor device.

A stroke-adjustable air conditioning compressor, in particular for motor vehicles, including a drive mechanism for pistons that move back and forth, the pistons being driven by an adjusting plate, such as a pivoting plate, pivoting ring or swash plate at an adjustable pivoting angle. The position of the pivoting angle is influenced inter alia by compressive forces, inertial forces and elastic forces that are active in the drive mechanism.

Air conditioning compressor

The invention relates to a compressor, particularly for air conditioners in motor vehicles, comprising a safety device for limiting high pressure, whereby the safety device is hermetically sealed until first responding, after which it slowly reduces the system pressure.

Compressor

A method for determining the piston stroke of a reciprocating piston machine having a variable stroke, for example a swashplate compressor, a pivoting plate compressor or a pivoting ring compressor, especially for air-conditioning installations in motor vehicles.
