Abstract

Disclosed is an vehicle-mounted temperature control system that suppresses a decrease in heating capacity by a heater core. A temperature control system includes a heater core utilizing heat of a heat medium; an engine heat exchanger utilizing exhaust heat of an engine to heat the heat medium; a condenser utilizing heat other than the exhaust heat to heat the heat medium; a heat circuit having the heater core and condenser; a communication flow path making the engine heat exchanger communicate with the heat circuit; and a connection state switching mechanism switching a flow state of the heat medium, between a first state and a second state. In the first state, the heat medium flows through the heat circuit, while flowing through the heater core, and in the second state, the heat medium flows through the heat circuit without flowing through the heater core. The heat circuit is arranged at a front of a passenger compartment, and the engine heat exchanger is arranged at a rear of the compartment.

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 the exhaust heat of the internal combustion engine and the heat released from the condenser of the refrigeration circuit provided separately from the internal combustion engine to heat the heat medium flowing into the heater core (for example, Patent Document 1 ). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent Laid-Open No. 2009-180103 [0006] 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 combustio...
