の空調に好適な空調設備に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to an air conditioner suitable for air conditioning a large space with a relatively high ceiling such as a theater, a public hall, and an atrium.

Description of the Related Art Conventionally, air conditioners applied to large spaces such as theaters, public halls, atriums, etc. share the return air duct suction port and the exhaust duct suction port that communicate with the air-conditioned room, and the duct is also partially In many cases, the return air duct and the exhaust duct are not mutually independent conduits.
Moreover, even if they are installed independently, the suction ports of them are often arranged at a short distance.

倍程度に相当する大風量となる。By the way, in large spaces such as theaters, public halls, and atriums, the floor to ceiling is high.
There are many examples in which the length is about 0 to 30 m. Also, the air volume is large when judged based on the floor area. Especially, in the theaters and public halls in Tokyo based on the Tokyo Metropolitan Building Safety Ordinance (Articles 56 to 71), the Tokyo Metropolitan Government Ordinance (Article 4), etc. The amount is 75m
3 / h · m 2 , the outside air volume during air conditioning is 25 m 3 / h · m 2 , which is 1.5 times to 2 times that of a typical office building.
The air volume will be about double.

するため、これを防止することは困難である。However, comparing the ventilation frequency with the volume of the space, the ventilation frequency of a general office building is about 10 times, whereas it is about 5 times in a large space such as a theater, a public hall or an atrium. Only half the ventilation is done. For this reason, in a space with a high ceiling, a temperature distribution is generated in the vertical direction, temperature stratification occurs, and when the temperature difference between the floor surface and the ceiling surface is compared, a temperature difference of about 5 to 7 ° C is generally generated. It has been reported. However, the cause of the temperature stratification occurs due to the difference in buoyancy due to the difference in temperature of air, and it is difficult to prevent this.

済であるという欠点があった。On the other hand, in the conventional air conditioning equipment, the return air duct and the exhaust duct are shared, and even if they are arranged independently, their suction ports are arranged close to each other and they are fixed in position. Therefore, it was impossible to select the intake height of the return air and the exhaust air of the air-conditioned room according to the season. Therefore, the temperature stratification of the air-conditioned room cannot be effectively used.For example, in the summer, cool air near the floor is exhausted to return warm air near the ceiling, or in the winter warm air near the ceiling is exhausted. Then, there was a disadvantage that it was uneconomical to return cold air near the floor.
