Abstract
A combined cooling and heating system having a simple design of a combined cooling and heat pump plant, especially for the heating and cooling of the passenger cells of motor vehicles. The concept of the invention is that the combined cooling and heat pump plant has a decompression device that fulfills the functions of a decompression device and a mode switch. The advantage of the invention is that dependent on the direction of flow, and thus the operational mode of the device, the decompression function and the blocking function, or the pressure relief function are realised by one component, the decompression device.
