Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2018202896
Kind Code:
A
Abstract:
To provide a vehicular air conditioner capable of expanding an outside air temperature range that enables dehumidification while maintaining heating capacity in a cabin.SOLUTION: A vehicular air conditioner 10 includes a heater core 32, a heat pump cycle device 20 and a temperature sensor 64 and an ECU. The heat pump cycle device 20 includes: a first indoor heat exchanger 22 disposed at a downstream side in an air-conditioning air flowing direction of the heater core 32; a second indoor heat exchanger 26 disposed at an upstream side in the air-conditioning air flowing direction of the heater core 32; and an outdoor heat exchanger 24. The temperature sensor 64 detects a passing air temperature that is a temperature of air-conditioning air that has passed through the heater core 32. Based on the passing air temperature, the ECU selectively switches a refrigerant circuit of the heat pump cycle device 20 to any of a cooling circuit, a heating circuit and a dehumidification heating circuit.SELECTED DRAWING: Figure 1
