Room temperature keeping device according to cooling load

摘要

The present invention relates to an air conditioner for a vehicle, which can prevent indoor air from becoming turbid due to a temperature difference with the outside due to continuous cooling during a summer air condition of the vehicle, to make the passenger feel uncomfortable, The present invention relates to a device for maintaining a room temperature according to a cooling load so that the temperature of the room can be prevented from being excessively decreased by controlling the amount of the refrigerant during the cooling and the temperature of the room can be appropriately maintained. A cylinder 20 for controlling the opening and closing of the valve 10 and a refrigerant pipe 20 connected to the cylinder 20 and the pipe 31 so that the refrigerant supplied from the valve 10 can form a cold air flow, And a temperature sensing unit 40 for sensing the temperature of the evaporator 30 and operating the cylinder 20 to adjust the supply amount of the refrigerant.
