In addition, the electromagnetic valves for the refrigerator-freezer system installed upstream of the evaporator in the refrigerator-freezer circuit are configured to open and close alternately with the electromagnetic valves for the near conditioner system, so that the solenoid valves for the refrigerator-freezer system and the near-conditioner system The low-pressure pipes are made independent up to just before the compressor, and a check valve is installed between the evaporator of the refrigerator-freezer system and the compressor installed downstream of the evaporator to ensure synchronized operation of each electromagnetic valve in the near conditioner system. This is a near-vehicle vehicle equipped with a refrigerator-freezer, which is characterized by rapidly reducing the compressor suction pressure to the pressure that allows freezing when the near-conditioner system is switched to the refrigerator-freezer system and the refrigerant passes through the refrigerator-freezer circuit. Condisiona.
