摘要： The invention relates to a method of refrigerant level monitoring in a refrigerant circuit of an air-conditioning or heat-pump system having a compressor and a refrigerant which may, depending on the operating point, be operated in the supercritical range. The method includes standstill level monitoring with the compressor switched off and/or in-operation level monitoring with the compressor switched on. In the case of in-operation level monitoring, the refrigerant overheat (dTü) at the evaporator is registered and, in the event of excessive overheat, it is concluded that there is underfilling. At a standstill, the pressure and temperature of the refrigerant are registered, and it is concluded that there is an improper refrigerant filling level if the pressure (pKM) lies below a minimum pressure value (pmin) or the temperature (TKM) lies above a maximum saturation temperature value (TS) with the pressure being outside a predefinable intended pressure range ([pu,po]).

摘要： The invention relates to a heat carrier comprising at least one collector pipe (1) for receiving the ends of flat pipes (10a), especially for a CO2 air conditioning unit for motor vehicles. The collector pipe (1) is formed by an open hollow profiled section (7) with edges (8, 9) forming a continuous longitudinal slit extending in a longitudinal direction and the ends of the flat pipes (10a), which are twisted at an angle of 90°, are received in a fluidically tight manner in the longitudinal slot. According to the invention, the edges (8,9) partially abut, forming a separating joint (4) and are partially rolled back, forming receiving openings for the ends of the flat pipes (10a). The receiving openings are produced by plastic deformation.
