摘要： An air-conditioning system operated with CO2 for a vehicle has a high-pressure section that is connected to the output of a compressor and includes a gas cooler, a low-pressure section that is connected to the suction side of the compressor and includes an evaporator, and an expansion member connecting the high-pressure section and the low-pressure section. The expansion member has a fixed restrictor with a throttle opening of predetermined length and diameter connected between an inlet from the high-pressure section and an outlet to the low-pressure section whereby under all operating conditions of the system, a pressure of refrigerant in the high-pressure section of the system is limited to values of less than 14 MPa. The restrictor can be connected in parallel with a pressure limiting valve and can include two or more different throttle openings that can be selectively connected for refrigerant flow.

摘要： An optimized CO2 air-conditioning system for a vehicle has individual components designed and/or matched to one another in such a way that if the high pressures in the high-pressure section deviate by up to ±30% from the optimum high pressures, the associated optimum performance figures are reduced by no more than 20%. The individual components include a controllable compressor, a gas cooler, an internal heat exchanger, an evaporator and an accumulator. As a result, a fixed throttle expansion member can be used between the high-pressure and low-pressure sections of the system.

摘要： The invention relates to a method and system for controlling a compressor in a refrigerant circuit of an air-conditioning system of a motor vehicle. The instantaneous load torque is determined and compared with a maximum limiting torque prescribed by an engine controller, and the compressor is controlled depending on the comparison value resulting therefrom. In order to avoid complete shutdown of the compressor, the instantaneous load torque is represented as a function of variables, such as compressor speed and high pressure of the refrigerant, and, using an inverted function belonging to this function, a control signal for the compressor, for example, a set-point value for the high pressure of the refrigerant, is determined as a function of the maximum limiting torque and employed to control the compressor.

摘要： In an air conditioner for a motor vehicle, which, for the purpose of contling the humidity, has in the ir duct suitable devices, controlled by a microcomputer. The microcomputer receives values for outside temperature, inside temperature and inside humidity, measured by sensors. From the values for outside temperature, inside temperature and inside humidity, the microcomputer determines the threshold humidity (l.sub.thresh) as the ratio of the saturated vapor pressure (P.sub.S) inside at the pane and the saturated vapor pressure (P.sub.i) of the inside air. If this difference (.DELTA.l) between threshold humidity (l.sub.thresh) and inside humidity (l.sub.i) falls below a stipulated value (x), dehumidification devices are actuated. If the stipulated value is exceeded, humidification devices are actuated.
