PURPOSE:To reduce uncomfortness generated at the time of actuating the ventilating device by changing the blow-off condition in linkage with the room ventilating device. CONSTITUTION:An air conditioning device 2 having a blow-off condition changing device for changing blwo-off conditions such as a blow-off angle, a blow-off air quantity, and the like, is provided in a room 1 to be air-conditioned provided with a ventilating device 3, and the above blow-off condition changing device is operated in linkage with the operation of the device 3. That is, when a power source switch 13 of the device 3 is turned ON, a fan motor 11 is supplied with power, and the device 3 begins to ventilate the room. The pressure difference between the inside and outside of the room 1 becomes large, infiltrated cool air increases and tends to stay in the vicinity of the floor surface. However, the air quantity notch of a control circuit 10 of the device 2 is switched to ''strong'' 16 by a relay 18, and hot air generated from the blow-off port reaches the floor surface. Therefore, the temperature difference between the upper and lower parts of the room can be held at a small value, and hence it makes the room comfortable. During the cooling operation, the increase in the room temperature due to the shortage in the faculty of the air conditioning device, generated during the ventilation, is suppressed by the increase in the cooling faculty because the air quantity of the device 2 is changed over to ''strong'', and the cooling effect on the body of a person due to wind is added. |
