Document Type and Number:
Japanese Patent JP2827208
Kind Code:
B2
Abstract:
PURPOSE:To arrange so that heating may be conducted right after starting when the temperature of cooling water is low right after the starting of an engine or the like, by making a constitution in which low temperature cooling water is introduced into an adiabatic tank and high temperature cooling water within the tank is pushed out and is supplied to a warm water type heater. CONSTITUTION:When an engine is started, cooling water discharged from the engine enters into a bypass passage 27, and in the case of cooling water being low in temperature, cooling water, due to a bypass open/close valve 28 containing thermowax 43 being closed, flows into an adiabatic tank 24 through a hose 35 or the like. Within the adiabatic tank 24, cooling water filling its inside is in advance kept warm under a high temperature, so high temperature cooling water is made to flow out of a flow out pipe 33 because of the inflow of cooling water, and flows out into a supply piping 20 through a flow quantity control valve 48 for a predetermined time only, and replaces low temperature cooling water within the supply piping 20 reaching a heater 11. After the elapsing of the predetermined time, high temperature cooling water is supplied to the heater 11 via a communicating passage 61 and a fixed flow quantity regulating valve 49, and is used to generate warm wind for heating.
