PURPOSE:To prevent cooling efficiency from being lowered at the engine starting time etc. by forming a cooling system as refrigerant is preferentially fed only to a cooling evaporator for a given period of time, when cooling load is high. CONSTITUTION:When a blower change-over switch 11 is turned to the high-position Hi, a relay 12 is electrified, and a circuit electrically communicated to a point of contact 12a, becomes conductive. In this mechanism, a motion timer 13 comes into action, the controller 9 of a refrigerator does not operate even if the power switch 14 of th refrigerator is turned on, a control valve 3 is kept opening, and refrigerant is fed only to a cooling evaporator 1. When the timer 13 indicates that a given period of time passed, the controller 9 of the refrigerator is allowed to operate, and refrigerant is also fed to the refrigerator. In this system, cooling efficiency is prevented from being lowered when cooling load is high.
