Title:
VEHICULAR AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2020104670
Kind Code:
A
Abstract:
To provide a vehicular air conditioner capable of efficiently using heat generated in an auxiliary heat source when heating or defrosting inside of a cabin.SOLUTION: A vehicular air conditioner 1 includes a refrigeration cycle 10, a high temperature side cooling water circuit 20 and a low temperature side cooling water circuit 40. A high temperature side heating medium circuit includes a radiator 21, a heater core 22, a branch part 24, a common flow passage 23, a flow rate control part 30 and an electric heater 26. The radiator 21 is a heat exchanger exchanging heat between cooling water and air outside a cabin. The heater core 22 is connected in parallel with the radiator 21, and radiates heat of the cooling water to blowing air W blown to an air conditioning target space. The branch part 24 enables branching into a cooling water flow toward the radiator 21 and a cooling water flow toward the heater core 22. The electric heater 26 heats the cooling water on the upstream side of the branch part 24 in the direction of the cooling water flow in the common flow passage 23.SELECTED DRAWING: Figure 1
