房装置。 It is equipped with a retarder that converts kinetic energy into thermal energy to generate vehicle braking force, and is installed on the engine cooling water inlet side after introducing engine cooling water from the retarder's heat exchanger to the heating heat exchanger. In a vehicle heating system in which the water is introduced into a water pump, a passage provided on a cooling water outlet side of the engine and communicating the cooling water discharged from the engine with an inlet side of a heat exchanger of the retarder, and an upstream side of the water pump. a bypass passage that bypasses the engine and communicates between the downstream side of the water pump and the inlet side of the heat exchanger of the retarder; and an opening/closing passage for the bypass passage. A heating system for a vehicle, comprising: an on-off valve for controlling the switching valve, a cooling water temperature detection means for detecting the engine cooling water temperature, and a control means for driving and controlling the switching valve and the on-off valve according to the detected cooling water temperature. Device.
