Abstract

An in-vehicle temperature control system includes: a heater core used to heat an inside of a vehicle cabin using heat of a heat medium; a first heating unit that heats the heat medium using exhaust heat of an internal combustion engine; a thermal circuit configured to circulate the heat medium between the heater core and the first heating unit; a distribution state switching mechanism that switches a distribution state of the heat medium between a first distribution state and a second distribution state; and a control device that controls the distribution state switching mechanism, wherein: the thermal circuit includes a bypass flow path disposed in parallel with the heater core.

Description

technical field [0001] The present disclosure relates to in-vehicle temperature regulation systems. Background technique [0002] There is known an in-vehicle temperature control system that uses a heater core provided in a thermal circuit of the vehicle to heat the interior of the vehicle. In particular, in this on-vehicle temperature regulation system, it is known to use exhaust heat from the internal combustion engine and heat released from a condenser of a refrigerating circuit provided separately from the internal combustion engine to heat the heat medium flowing into the heater core (for example, Japanese Patent Laid-Open 2009-180103). [0003] Furthermore, in terms of vehicle design, it may be necessary to mount the internal combustion engine and the heater core separately. In this case, the piping for the heat medium between the internal combustion engine and the heater core is long. Therefore, when the heat medium heated by the internal combustion engine is inten...
