PURPOSE:To save energy by a simple structure wherein a cooling unit and a hot water heat exchanger are provided in parallel to a fuel vaporizer through a change-over valve in a vehicle using liquefied combustible gas as fuel. CONSTITUTION:In cooling, a solenoid valve 15 is closed and a solenoid valve 21 is open and liquefied combustible gas is supplied to a piping system 20 and reduced its pressure at a throttle 22 in order to enter a cooler 25, within which the gas is heat-exchanged by means of a blower 26 with the air circulating inside the vehicle in order to cool said circulating air by evaporating itself, and, after that, supplied through the hot water heat exchanger 24 and a carbureter 17 to an engine. The cooling control is performed by controlling the operation of the blower 26 and at the same time by opening a solenoid valve 30 so as to control the gasification of the liquefied combustible gas within the hot water heat exchanger 24. In case that no cooling is required, the solenoid valve 15 is open and the solenoid valve 21 is closed so as to flow the liquiefied combustible gas to a piping system 19 as indicated with the dashed lines and arrow heads. In such a manner as mentioned above, the sure gasification of liquefied combustible gas in cooling and as well as the energy-saving cooling with simple arrangement can be accomplished. |
