[0002]

[Prior art]

(1) Normally in a building office or the like, an air conditioner having an outside air introduction function (hereinafter abbreviated as an air conditioner as necessary)
Is Econo Fresh Tenume (RPIF-1000F) listed in the multi-air conditioner catalog for Hitachi Building '91 .5.
M), it is installed indoors or above the ceiling,
When installing the air conditioner, a connection between the outside wall opening and the air conditioner was made on site by a special duct for transporting outside air from the outside to the air conditioner and a special duct for discharging indoor air to the outside. I have. Air conditioning in a space outside the living space, such as a corridor, has been performed by natural ventilation.

(2) An air conditioner having an outside air introduction function is adopted, and as shown in Japanese Patent Application Laid-Open No. 60-108627, an air conditioning system that does not use a dedicated duct can take in and exhaust corridor air in each room. There is a system in which an individual air conditioner is provided and an outside air introducing means is provided in a corridor to introduce outside air using the corridor as a mixing chamber.

[0004]

In the conventional example (1), installation of a dedicated duct behind the ceiling is required with the installation of the air conditioner, which complicates the installation work and lengthens the work period. Further, since a dedicated duct is required, the system cost increases.

[0005] Further, when it is necessary to air-condition a non-living space such as a corridor as in the current intelligent building,
Since a dedicated air conditioner is installed in the corridor or air conditioning is performed by natural ventilation, the former method increases the cost of the system, and the latter causes a problem that sufficient air conditioning cannot be performed depending on outdoor conditions.

In the conventional example (2), since the corridor is used as a mixing chamber, as in the present office building, the outside air introduction operation / air conditioner operation is performed only in some rooms at night or the operation is performed. If the rooms to be operated are scattered, it is difficult to obtain the required amount of outside air, and it is necessary to introduce more outside air than necessary into the building, resulting in poor operating efficiency and the ability of air conditioners to be increased. Must.

Further, since the corridor is used as a mixing chamber, when each room is used in various ways in a tenant style as in a general building at present, contaminated air generated from one room is contaminated by another room. There is a problem that it spreads to.

Further, since the corridor is used as a mixing chamber, the air introduced into each room is always a mixed air of room air and outside air, and it is difficult to increase the amount of introduced outside air to a certain amount or more. as, or when the indoor heat load OA has progressed significantly large, a turn of the seasons
In any intermediate period, even if the outside air temperature is lower than the room temperature, energy saving operation such as outside air cooling (total outside air introduction) cannot be performed.

Further, in the conventional example, since the outside air is collectively taken in from one outside air introduction means for each floor, the current complicated building, that is, a building with a large floor area, and a room / corridor arrangement. In complex buildings,
A room with extremely low outside air introduction efficiency, such as a room farther than the outside air introduction means, is created.
