When the room temperature is higher than the first set temperature (eg, 25 ° C.) and the outside temperature is lower than the second set temperature (eg, 22 ° C.), the control panel 140 outputs an upper fan driving control signal to the upper fan 120. In addition, the upper fan 120 is driven to force the outside air to be discharged into the room.

Therefore, the outdoor air discharged into the room is cooled by lowering the temperature of the indoor air.

The air conditioner driver 146 that receives the stop control signal stops driving of the air conditioner 200 by cutting off the power supply.

Next, the operation of the air introduction air cooling apparatus 100 according to the second embodiment of the present invention will be described.

The switching of the cooling mode is performed according to the degree of contamination of the outside air that is inhaled. If there is no contamination of the outside air, the first cooling mode is performed by cooling only with pure outside air, and if the outside air is contaminated, the outdoor air and the indoor air are plate-shaped. The outside air absorbed by the heat exchanger 150 to absorb heat is directly discharged to the outside, and the second air cooling mode is performed by cooling the indoor air cooled by discharging the heat to the room R.

This will be described in detail below.

First, an operation when the indoor temperature is higher than the first set temperature and the outside temperature is lower than the second set temperature will be described.

When the room temperature is higher than the first set temperature and the outside temperature is lower than the second set temperature, the first cooling mode and the second cooling mode for introducing the outside air are selectively performed according to the pollution of the outside air.

If there is no contaminant in the outdoor air under such a temperature condition, a first cooling mode is performed in which only the outside air is directly supplied to the room and cooled.

Therefore, the outside air forcibly sucked by the outside air discharge fan 122 is discharged to the outside through the outside air discharge duct 113a and the outside air outlet 113, and the indoor air is forcibly driven by the upper fan 120. The indoor air sucked through the suction port 114 is discharged to the upper discharge port 112 via the indoor air duct 162. In this process, the outdoor air and the indoor air are heat-exchanged in the plate heat exchanger 150, and the outdoor air is indoor air. By absorbing the heat of the hot air to the outside air of the indoor air to cool the air is discharged to the upper discharge port 112 and cooled.

Therefore, in the first cooling mode, the upper fan 120 forcibly sucks only the outside air and discharges it to the upper discharge port 112. In the second cooling mode, the upper fan 120 forcibly sucks the heat-exchanged indoor air and the upper discharge port 112. To be discharged.

On the other hand, when the room temperature is higher than the first set temperature (25 ° C in the above example) and the outside air temperature is higher than the second set temperature (22 ° C in the example), the first and second cooling modes are not performed and the cooling mode by the air conditioner is performed. The third cooling mode is performed.

The control panel 140 may stop the driving of the upper fan stop control signal and the outside air discharge fan 122 for stopping the driving of the upper fan 120 when the outside temperature is higher than the second set temperature regardless of the room temperature. Outputs the air discharge fan stop control signal.

When the indoor temperature is lower than the first set temperature, the air conditioner stop control signal for stopping the operation of the air conditioner is output to the air conditioner driver 146 to stop the operation of the air conditioner 200. As described above.
