　しかしながら、特許文献１に示すような従来の車両用エアコンシステムでは、エアコンＥＣＵと各アクチュエータの間は夫々共通の制御線によって接続されている。よって、エアコンＥＣＵと各アクチュエータとの間に多数のワイヤーハーネスを配置する必要がある。このようなワイヤーハーネスは、車両全体、車両用空調装置全体において相当多数使用されることになる。このため、ワイヤーハーネスの配線が複雑化する、ワイヤーハーネスの重量が増加する、ワイヤーハーネスの取付の作業工数が増大するという問題がある。 However, in the conventional vehicle air conditioner system as disclosed in Patent Document 1, the air conditioner ECU and each actuator are connected by a common control line. Therefore, it is necessary to arrange a number of wire harnesses between the air conditioner ECU and each actuator. Such a wire harness is used in a large number in the entire vehicle and the entire vehicle air conditioner. Therefore, there are problems that wiring of the wire harness is complicated, weight of the wire harness increases, and man-hours for mounting the wire harness increase.
　そこで、本発明は、制御部と各アクチュエータを接続するワイヤの数を削減して配線を簡略化できると共に、車両に搭載されるワイヤーハーネスの重量を軽量化することができ、さらに、ワイヤーハーネスの取付時における、ワイヤの取り回しを容易にし、作業性を向上させることができる車両用空調装置を提供することを目的としている。 Therefore, the present invention can simplify the wiring by reducing the number of wires connecting the control unit and each actuator, reduce the weight of the wire harness mounted on the vehicle, and further reduce the weight of the wire harness.

Is charged. Furthermore, the battery 144 mounted on the air conditioner and the actuator 10 are connected by a wire harness 148 for a battery-side power supply line, and power is supplied to the actuator 10. For this reason, the wire for supplying electric power to the actuator 10 only needs to connect the air-conditioner-equipped battery 144 provided in the air conditioner main body 6 to the actuator 10, and the wire for supplying electric power to the actuator 10 can be shortened. As a result, the weight of the wire harness mounted on the vehicle 2 can be reduced, and the number of steps for connecting the wire harness of the functional components in the vehicle assembly process can be reduced.
　本実施形態においては、各制御部側送受信機３０に対し、１つずつ機能部側送受信機３２が備えられているが、変形例として、１つの制御部側送受信機３０に対し、複数の機能部側送受信機３２を配置し、制御部側送受信機３０が選択的に意図する機能部側送受信機３２に信号を送ることも可能である。この場合、制御部コネクタ２６の数を低減する又は、一部の制御部コネクタ２６を電源線用端子のみを備えた制御部コネクタ２６に変更することも可能となる。 In the present embodiment, one functional unit-side transceiver 32 is provided for each control-unit-side transceiver 30. However, as a modified example, a plurality of functions are provided for one control-unit-side transceiver 30. It is also possible to arrange the unit-side transceiver 32 and send a signal to the function-unit-side transceiver 32 that the control-side transceiver 30 selectively intends. In this case, it is possible to reduce the number of the control unit connectors 26 or to change some of the control unit connectors 26 to the control unit connectors 26 having only the power line terminals.
