Abstract

PROBLEM TO BE SOLVED: To reduce a load of an air conditioning operation during a cooling operation and during a heating operation by a method wherein a signal for reducing a degree of opening of surrounding atmosphere feeding port is outputted to a means for adjusting a degree of opening of air feeding port in the case that an air speed of surrounding air entering through the surrounding air feeding port is more than a predetermined value. SOLUTION: When a surrounding air feeding port 11 is opened to take the surrounding air, the surrounding air strikes against an air receiver 14 arranged at the surrounding air feeding port 11, resulting in that the air receiver 14 is oscillated toward an inner side at an angle corresponding to an air speed of the surrounding air. Then, in the case that the oscillation angle is more than a predetermined value, a switch is changed over from OFF state to ON state, a controller 6 controls the means 5 for adjusting a degree of opening of the air feeding port in such a way that a degree of opening of the surrounding air feeding port 11 is reduced in response to the changed- over state. With such an arrangement as above, a degree of opening of the surrounding air feeding port 11 is reduced. Namely, a surrounding air feeding amount per unit time in the case that an air speed of the surrounding air is more than the predetermined value and one in the case that an air speed of the surrounding air is less than the predetermined value are approximately the same to each other.

TECHNICAL FIELD The present invention relates to an air conditioner for cooling and heating a building.

[0002]

2. Description of the Related Art As a conventional air conditioner, for example, as described in Japanese Patent Application Laid-Open No. 4-281126, an outside air supply port that communicates with the outside and a return air port and a discharge port that communicates with the room. Inside the main body having, an air blower whose air supply side faces the outside air supply port and the return air port and the air outlet side faces the air outlet, and a coil (heat exchanger) that heats or cools the air blown out of this air blower, and There is known a damper provided with an open / closed outside air supply port and a drive device for driving the damper.

[0003]

However, in such a conventional air conditioner, the opening degree of the outside air supply port is kept constant regardless of the wind speed of the outside air entering from the outside air supply port. , The outside air supply amount changes depending on the wind speed of the outside air entering from the outside air supply port. Therefore, when the outside air supply port is open and the wind speed of the outside air is high, the outside air supply amount is too large, and the outside air supply port is open, and the wind speed of outside air entering from the outside air supply port is extremely slow. In this case, if the temperature of the room is higher than the outside temperature, the air in the room will flow out from the outside air supply port, so that the problem of increasing the air conditioning load during the cooling operation and the heating operation becomes large. there were.

In view of the above problems, an object of the present invention is to provide an air conditioner capable of reducing the load of air conditioning during the cooling operation and the heating operation.
