Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an air conditioning method in an office building that does not require an air supply duct for supplying conditioned air.

(Prior art and its problems) In the conventional air conditioning method for office buildings, an air conditioning machine room is installed near the outer shell of the building, an air conditioner is installed in the same room, and the heat source is pumped from the underground heat source machine room. Cooling or heating air was created using a heat exchanger using cold water or drought water, and the air was supplied to the living space through an air supply duct and an air outlet provided in the ceiling.

However, in this method, even though the so-called living area where the inner layer of the living space actually resides is below the resident's nominal g& line, that is, the height of about 1.6 m from the floor level. This method could not be called a rational air conditioning method because it had to first air condition the space above the breathing line, that is, the non-residential area, and then air condition the residential area. In addition, when implementing this method, it is necessary to run the air supply duct through the beam that supports the ceiling material, which not only increases the piping work cost, but also reduces the strength of the beam due to the penetration of the air supply duct. Since it is necessary to compensate by increasing the height of the beam, it becomes necessary to increase the floor height of the building, which has the disadvantage of increasing the construction cost of the building.

(Object of the Invention) In order to solve the problems of the prior art described above, the present invention uses the underfloor space of an office building as a sub-live plenum chamber and the space inside the ceiling as a return plenum chamber, omitting the air supply duct, and providing conditioned air. The purpose of this invention is to provide a new and rational air conditioning method in which air conditioning is first performed from the living area by using a floor blowing type.

(Disclosure of the Invention) The air conditioning method according to the present invention provides an air conditioning machine room adjacent to the living space of an office building, and connects the ceiling space and the underfloor space through an air conditioner installed in the air conditioning machine room. It is characterized by having an air outlet on the floor and an air suction port on the ceiling.

(Action of invention) The operation of the present invention will be explained using heavy water as an example as shown in the drawings.

That is, the upper and lower parts of the internal space of an office building are partitioned by ceiling material 1 and floor material 2, and the entire living space a1 between the ceiling material 1 and floor material 2 is open between the ceiling material and the ceiling material 1'. The space between the ceiling space 61 and the floor material 2 and the subfloor 2' is defined as the underfloor space C, and the outer shell side of the living space α is partitioned off with a partition plate 6, and the air conditioner 4 is installed. Sky for! 4 constitutes machine room d. The air conditioner 4 installed in this air conditioning machine room dLC is a floor-standing, bottom-blowing fan coil unit, which uses cold or hot water pumped from an underground heat source machine room to supply cooling or heating air through a heat exchanger 4□. and create fan 4
2VC, this conditioned air is supplied into the underfloor space C, and the ceiling space 6 and the underfloor space C are in communication via the air conditioner 4 in the air conditioning machine room d. Connecting ports for connecting air outlets are formed at appropriate locations on the flooring material 2,
A fan 5 for blowing air is attached directly to the connection port, and an air outlet 6 is attached to the connection port through a large plate of the office desk or side desk A through the 7 reshikiru duct 4. Air is blown and conditioned air is blown out from the air outlet 6 into the living area of the living space α. A plurality of air suction lowers . . . 7 are provided in the ceiling material 1 to collect air in the living space α into the ceiling space. The air recovered in the ceiling space bVrc is sucked into the suction port at the upper end of the air conditioner 4, and is blown out from the air outlet 6 as the conditioned air L2'' (again into the living space α) as described above.

In other words, the space in the ceiling and the space under the floor C are communicated via the 9L air conditioner 4 in the air conditioning machine room d, and conditioned air is blown into the living space α from the air outlet 6 provided in the flooring 2. A conditioned air circulation system is formed by four spaces: living space a, ceiling space b, air conditioning machine room d, and underfloor space C.

In addition, if equipment that is a heat source such as a computer is installed in the living space α, a small air conditioner 8 may be suspended from the ceiling base 1' to handle this partial heat burden. Cooling air is blown out toward the equipment from an air outlet 82 provided in the ceiling material 1 through a duct 81 that does not penetrate the beam.

(Effects of the Invention) As described above, according to the air conditioning method according to the present invention,
Blenheim chamber supplies the underfloor space of office buildings.
The space inside the ceiling is made into a plenum chamber, and conditioned air is supplied from the floor side into the living space, which is different from the conventional air conditioning method where conditioned air is supplied from the ceiling side. It is possible to create a comfortable living environment in a short time after starting cooling or heating operation, and since the space inside the ceiling and under the floor are used as a passageway for the outside air, it is possible to air-condition the living area. Not only does it eliminate the need for a plumber to install an air supply duct to supply air, but it also eliminates the need to consider the reduction in strength of beams that occur when passing through the air supply duct, making it possible to reduce the floor height of the building. It does not need to be expensive and does not increase the construction cost of the building.Furthermore, since the air outlet is on the floor side, repair, inspection, and control can be performed extremely easily. It can be effective.
