  The ventilation air passage 15 is provided with a ventilation damper 16 for blocking communication between the outdoor side and the inside of the ventilation air conditioner 1 and a smoke sensor 17 for detecting smoke on the ventilation port 13 side.

  Further, an operation unit 19 having an operation switch 18 for starting and stopping operation is provided outside the ventilation air conditioner 1.

  In addition, a refrigeration cycle is formed by a refrigeration pipe 22 that connects the compressor 20 that compresses the refrigerant, the first heat exchanger 4, the expansion mechanism 21 that expands the refrigerant, and the second heat exchanger 3 and passes the refrigerant. .

  The compressor 20, the circulation blower 6, the ventilation blower 14, the wind direction louver 8, the ventilation damper 16, the expansion mechanism 21, and the first fine water droplet generation means 9 are controlled, and the smoke sensor 17 and the input of the operation unit 19 are controlled.

The airflow direction louver 8 is closed, the compressor 20 and the circulating air blower 6 are operated, and the refrigerant that has been increased in temperature and pressure by the compressor 20 passes through the refrigeration pipe 22 and is passed from the room by the circulating air blower 6. Heat is radiated to the sucked air, moved to the expansion mechanism 21 and depressurized, becomes low temperature and low pressure, moved to the second heat exchanger 3, and the circulation blower 6 absorbs the heat of the air sucked from the room. Return to the compressor 20.

  In other words, the air sucked from the room passes through the circulation air passage 7 and the refrigerant absorbs heat in the second heat exchanger 3, so that the sucked air is cooled and falls below the dew point temperature, and the second heat Air is sent to the first heat exchanger 4 while causing condensation in the exchanger 3 and reducing the amount of retained water. Since the refrigerant dissipates heat by the first heat exchanger 4, the sent air is warmed again.

The effect of the configuration and the ventilation fan 14 not provided in the ventilation air conditioner 1 are not changed even if they are separately installed.

  Moreover, the 1st heat exchanger 4 and the 2nd heat exchanger 3 should just be able to heat-exchange between a refrigerant | coolant and air, for example, is a structure using the piping and fin arranged in length and width, and a material is copper with good heat conduction. And aluminum as the main raw material.
