Abstract

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.

Description

[Detailed Description of the Invention] - The present invention relates to an air conditioner that changes the conditions for blowing out conditioned air in conjunction with an indoor ventilation system, and an object of the present invention is to reduce the discomfort that occurs when the ventilation system operates.

I will explain what happens when ventilation is performed using a conventional air conditioner with constant blowout conditions. FIG. 4 shows the state inside a room C when ventilation is performed by a ventilation device B while heating is performed by a conventional air conditioner A. D is the warm air blown out from the air conditioner A, and E is the cold air that enters through the gaps between the walls and windows of the room C. If ventilation is not used, there is little pressure difference between indoors and outdoors, so there is little cold air intrusion, and the warm air blown from the air conditioner will not reach the floor and make your feet cold, but ventilation is necessary. When the air pressure starts, the pressure inside the room becomes lower than that outside, and as explained in Figure 4, the cold air E enters and stagnates near the floor, so the warm air cannot reach the floor and rises, causing the air to fall under your feet. It gets cold and makes the residents feel very uncomfortable. When ventilating a shelter during cooling, warm air from outside enters through gaps in the walls and windows of the room, causing the room temperature to rise and the indoor temperature distribution to widen due to insufficient capacity, causing discomfort to the occupants. . As described above, the conventional air conditioner in which the blowing conditions are uniform regardless of the operation of the ventilation device has the disadvantage that it gives a pleasant feeling to the occupants when the ventilation device is used.

The present invention overcomes the drawbacks of the prior art by changing the blowout conditions in conjunction with the ventilation system.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, 1 is an air-conditioned room, 2 is an air conditioner body installed on the upper wall of the air-conditioned room 1, and 3 is a ventilation device for discharging air from the air-conditioned room to the outside. The air conditioner main body 2 includes a heat exchanger 4. Fan 5. It has a built-in blow-off vane 6, etc. 7 is an inlet of the air conditioner main body 2, and 8 is an outlet. 9 is a control circuit for the ventilation system 3;
10 is a control circuit of the air conditioner body 2; 11 is a fan motor A112 of the ventilation device 3; 13 is a power switch A of the ventilation device 3; and 14 is a fan motor B11 of the fan 5.
6 is the power switch B of the fan 5 116 is the high air volume notch of the fan 5, 17 is the low air volume notch, 18 is the power switch A
13 is a relay switch that switches from a weak air volume notch 17 to a strong air volume notch 16 when the air volume notch 13 is turned on. □ The above configuration will be explained during heating. During heating, the blow-off vane 6 is directed toward the floor of the air-conditioned room 1 to perform air conditioning. Then, since the ventilation system 3 is stopped, when the power switch 16 is closed, the motor 4 is energized through the low air volume notch 1a, the fan 5 has a low air volume, and the warm air blown out from the air outlet 8 is low. It's the air volume. Of course, since only natural ventilation is used for ventilation, there is less cold air entering the air-conditioned room 1, and even with a weak air volume, the warm air can reach the floor, resulting in a comfortable state with little difference in temperature between the top and bottom of the room. Subsequently, when the power switch A13 of the ventilation device 3 is turned on, the power supply 11 is energized, and the ventilation device 3 starts ventilation. Then, the pressure difference between the inside and outside of the air-conditioned room 1 increases, and the cold air that enters increases and tends to stagnate near the floor surface. However, the air volume notch of the control circuit 1Q of the air conditioner main body 2 is switched to strong 16 by the relay 18,
As shown in FIG. 1, the hot air coming out of the air outlet 8 reaches the floor, so the difference in temperature between the top and bottom of the room can be kept small, making the room comfortable.

In addition, the room temperature rise due to the capacity factor of 1° that occurs during cooling and ventilation is increased by switching the air volume of the air conditioner main body 2 to a strong level, increasing the capacity and adding to the cooling effect of the wind on the human body. You can stay comfortable.

As in the above embodiment, the cooling effect on the human body caused by air during cooling can also be achieved by changing the blowing angle.

Further, although the air volume is changed in one embodiment, the same effect can be obtained by changing the air speed.

As is clear from the above description, since the air conditioner of the present invention changes the blowout conditions in conjunction with the indoor ventilation system, it has the effect of alleviating the discomfort that occurs when the ventilation system operates. It is.
