Description
上記目的を達成するため、請求項１に記載の発明では、前席用空調ユニット（２０）と、後席用空調ユニット（５０）と、電気機器（７０）と、機器冷却通路（５９）とを備える。前席用空調ユニットは、車両前方側に配置され、主に車両前席側に空調空気を送風する。後席用空調ユニットは、車両後方側に配置され、主に車両後席側に空調空気を送風する。電気機器は、車両後方側に配置され、作動に伴って発熱する。機器冷却通路は、前記後席用空調ユニットで冷却された空調空気を車室内を介することなく電気機器に供給する。機器冷却通路は、電気機器を冷却した後の空調空気を後席用空調ユニットに循環させる。 In order to achieve the above object, in the invention according to claim 1, the front seat air conditioning unit (20), the rear seat air conditioning unit (50), the electric device (70), and the device cooling aisle (59) are used. To be equipped. The front seat air conditioning unit is arranged on the front side of the vehicle and mainly blows air conditioning air to the front seat side of the vehicle. The rear seat air conditioning unit is arranged on the rear side of the vehicle and mainly blows air conditioning air to the rear seat side of the vehicle. The electrical equipment is located on the rear side of the vehicle and generates heat as it operates. The equipment cooling passage supplies the conditioned air cooled by the rear seat air conditioning unit to the electric equipment without passing through the vehicle interior. The equipment cooling passage circulates the conditioned air after cooling the electric equipment to the rear seat air conditioning unit.
後席用冷媒配管１１ｂには、後席用膨張弁１５の冷媒流れ方向上流側に、冷媒開閉弁１８が設けられている。冷媒開閉弁１８は、空調制御装置８０から出力される制御電圧によって、後席用冷媒配管１１ｂを開閉する。冷媒開閉弁１８を開くと後席用蒸発器１７に冷媒が流れ、冷媒開閉弁１８を閉じると後席用蒸発器１７に冷媒が流れなくなる。つまり、冷媒開閉弁１８を開いた場合には、前席用蒸発器１６及び後席用蒸発器１７の双方に並列的に冷媒が流れる。 The rear seat refrigerant pipe 11b is provided with a refrigerant on-off valve 18 on the upstream side of the rear seat expansion valve 15 in the refrigerant flow direction. The refrigerant on-off valve 18 opens and closes the rear-seat refrigerant pipe 11b by the control voltage output from the air conditioning control device 80. When the refrigerant on-off valve 18 is opened, the refrigerant flows to the rear-seat evaporator 17, and when the refrigerant on-off valve 18 is closed, the refrigerant does not flow to the rear-seat evaporator 17. That is, when the refrigerant on-off valve 18 is opened, the refrigerant flows in parallel to both the front seat evaporator 16 and the rear seat evaporator 17.
