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.

摘要: An integrated modular collector—heat exchanger unit for motor vehicle air conditioners and the like has a collector housing in which a collecting space and a heat exchanger unit are disposed. The heat exchanger unit includes two separate heat exchanger ducts which are in a thermal contact. One heat exchanger duct has a helical course and is part of a first flow duct which extends from a housing inlet to a housing outlet in the collector housing. The other heat exchanger duct is part of a second flow duct extending between the collecting space and a housing connection. This other heat exchanger duct also has a helical course, its coils in each case being in a thermal contact with at least one adjoining coil of the first of the first heat exchanger duct.

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: 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.
