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： A control device is provided for a refrigerant circuit of an air conditioner, divided by a compressor and a vent element into a high-pressure side and a low-pressure side. The control device includes a high-pressure-side control part and a low-pressure-side control part for controlling one or more controllable high-pressure-side or low-pressure-side system components. The two control parts are coupled with one another, with at least one influential parameter of one control part forming a coupling parameter that is coupled into the other control part as an influential parameter that is effective there as well. The control device is useful for carbon dioxide air conditioners of motor vehicles.

摘要： The subject of the present invention is a motor control system having a monitoring circuit for monitoring PWM control for a DC electric motor, the PWM control comprising a power end stage having at least one field effect transistor, which controls the current at the DC electric motor. The motor control system is designed to monitor the current at the DC electric motor. The motor control system detects the voltage drop across the field effect transistor and comprises a temperature sensor for detecting the temperature of the field effect transistor. Furthermore, the motor control system is designed to determine the resistance of the field effect transistor from the detected temperature thereof, and to determine the current at the DC electric motor from the resistance of the field effect transistor and from the voltage drop across the field effect transistor.
