[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for taking in outside air using the space inside the ceiling, which constantly takes in fresh outside air into the room at the same time by using the space inside the ceiling, and at the same time, to supply appropriate cold and warm air. Regarding the device.

[0002]

2. Description of the Related Art It is well known that normally a clean environment is required by introducing fresh outside air at the same time when heating and cooling a room. As a means for introducing such outside air, in the conventional case, the outside air is heated to a proper temperature by a cooler or the like and is supplied to the indoor air suction / inhalation device side which is installed on the ceiling of each room by duct piping. It was.

[0003]

However, since most of these methods are performed by duct piping as described above, it is very difficult to provide a large number of ducts in a narrow space in the ceiling. Of course, there is a drawback that the situation such as leakage from the connection part during air supply may occur repeatedly, and especially in each room, depending on the relationship between inside and outside, gathering etc. It required complicated procedures such as adjusting the air flow rate and temperature.

[0004]

In view of the above problems, the present invention takes in outside air by utilizing the space inside the ceiling without requiring any complicated work such as duct piping and sucks each indoor air. By adjusting the air supply equipment, it is possible to constantly and evenly supply the outside air into the room at the same time as the supply of cool and warm air, or to deliver a large amount of outside air to a required place or a small amount of outside air, which is extremely convenient. Its purpose is to provide a method and apparatus for taking in outside air.

That is, the outline of the present invention is as shown in the drawings.
An outside air heat exchanger A is installed in the vicinity of the outside air intake D, and an air outlet of the outside air heat exchanger A is opened in a space S in the ceiling where the air conditioning unit B is installed. Fresh air that has been heat-exchanged to an appropriate temperature is temporarily supplied from the air supply port to the space inside the ceiling, and the outside air that flows into the ceiling is placed in the ceiling through the outside air inlet of the air conditioning unit B. The present invention aims to provide a method and an apparatus for taking in outside air using the space inside the ceiling, which is characterized in that such outside air is sent to the inside of the room at the same time as the sending of cold and warm air.

In the above embodiment, the space S in the ceiling is
Several air-conditioning units B having the same capacity are arranged on the ceiling at appropriate distance intervals so that the air flow rate is made small in the vicinity of the air supply port for the outside air and gradually increases as the air flow goes away. The units B are sequentially arranged in a different manner so that the ventilation bodies in the space in the ceiling are made substantially equal to the perspective and the air conditioning units B are adjusted to deliver a predetermined amount of cold / warm air to a required place in the room, or a space in the ceiling. By arranging several air-conditioning units B having different capacities in the ceiling of the air-conditioner with different capacities at a small level in the vicinity of the air supply port for the outside air, and gradually arranging the capacities sequentially as the distance increases. The air blower into the room is made to have a substantially uniform perspective.

[0007]

The present invention has the above structure,
Fresh outside air taken into the outside air heat exchanger A is heat-exchanged from the outside air intake D to an appropriate temperature and flows out to the space S inside the ceiling from the air outlet 1. Then, the inflowing outside air is introduced into the cabin from the outside air inlet 2 of the unit by the operation of each air conditioning unit B arranged on the ceiling portion, and this tries to blow the air into the room through the air outlet 3 together with the cool and warm air. Further, the wind power and capacity of each indoor air conditioning unit B installed on the ceiling at the time of sending cold / warm air are set to be small in the vicinity of the outside air supply port and gradually increased as the distance increases. By sequentially arranging the parts differently, it is possible to easily obtain substantially uniform or predetermined air conditioning expansion throughout the room.
