| 摘要 |
The invention relates to an air-conditioning device for a motor vehicle, comprising a refrigerant circuit (12) with - a compressor (14) for compressing a refrigerant, - a condenser or gas cooler (18) which is connected downstream of the compressor (14) on the refrigerant side for liquefying or cooling the compressed refrigerant, and - an evaporator (26) which is flowed through by an air flow (20) to be cooled, is connected downstream of the condenser or gas cooler (18) on the refrigerant side, and comprises a first evaporator section (261) and a second evaporator section (262), wherein the first evaporator section (262) is connected downstream of the first evaporator section (261) both on the air side and on the refrigerant side, and wherein a first expansion member (22) is arranged upstream of the first evaporator section (261) on the refrigerant side and a second expansion member (30) is arranged downstream of the first evaporator section (261) and upstream of the second evaporator section (262), in each case for throttling the refrigerant flow in a regulatory manner. The invention is distinguished by the fact that the first expansion member (22) is configured as a thermostatic expansion valve (24) and the second expansion member (30) is configured as a control valve (32). |
