Title:
ON-VEHICLE TEMPERATURE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2022178219
Kind Code:
A
Abstract:
To provide an on-vehicle temperature control system which can perform heating in two forms and has a simple constitution.SOLUTION: An on-vehicle temperature control system 1 has: a refrigeration circuit 2 which has a heat exchanger 22 between media for dissipating heat from a refrigerant to a heat medium and performs a refrigeration cycle; and a heat circuit 4 having a heater core 43 used in heating in a cabin, the heat exchanger between the media and an engine heat circuit 5. The heat circuit has a first communication passage 4a communicating with an outlet of the engine heat exchanger, an outlet of the heat exchanger between the media, and an inlet of the heater core, a second communication passage 4b communicating an inlet of the engine heat exchanger, an inlet of the heat exchanger between the media and an outlet of the heater core, and an adjusting valve 45. The adjusting valve is controlled to a first state of flowing a heat medium from the heat exchanger between the media to the heater core when heating is performed using heat obtained in the refrigeration cycle, and to a second state of flowing the heat medium from the engine heat circuit to the heater core when heating is performed using heat obtained from an internal combustion engine.SELECTED DRAWING: Figure 3
