Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioning system useful for use in large space buildings such as multipurpose halls, theaters, and bleachers in outdoor stadiums such as baseball stadiums.

Conventionally, in outdoor stadiums such as baseball stadiums and outdoor theaters, even if the seats are covered with roofs, the spaces are open and heat loss is large, so heating and cooling systems have not been installed. It wasn't set up.

Furthermore, since conventional halls, theaters, etc. are closed spaces, they are equipped with heating and cooling systems to allow for comfortable viewing. However, the space to be cooled and heated has a very large volume, and the entire space is heated and cooled, so if the space is full or nearly full, there is no problem with air conditioning costs, but other than that, air conditioning costs are not a problem. At the same time, the air conditioning cost becomes a large part of the maintenance cost, which is not desirable.

In this way, conventionally, in large space buildings,
It was difficult to provide economical heating and cooling.

This invention was made in view of the above circumstances,
The purpose is to:
Ensures heating and cooling of areas where people live in large buildings.
The objective is to provide an air conditioning system that can be adequately and economically operated, by installing air supply pipes and air recovery pipes for heating and cooling under the floors of buildings, and separately connecting these air supply pipes and air recovery pipes to each other. Connected to the outflow channel and inflow channel provided in the seat,
For all seats in the building, air for heating and cooling is blown from the outflow path of a certain seat toward neighboring seats, and air blown from other nearby seats is blown through the inflow path of the certain seat. It is configured to be collected into a collection pipe, and the area around each seat can be selectively heated and cooled.

The present invention will be explained below with reference to the drawings. FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure indicates a floor of a building. An air supply pipe 2 and an air recovery pipe 3 are arranged under the floor 1.

On the other hand, inside the seat 4 arranged on the floor 1, an outflow path 5 having air discharge ports 5a, 5a and an inflow path 6 having air intake ports 6a, 6a are formed. In this embodiment, the air outlet 5a is located at the seat 4.
The air intake port 6a is provided at the upper part of the backrest of the seat 4.
is provided on the front end surface of the

The outflow path 5 is connected to the air supply pipe 2 through a connecting pipe 7, and the inflow path 6 is connected to the air recovery pipe 3 through a connecting pipe 8. Connecting pipes 7 and 8 are provided with flow control valves 7a and 8a, respectively. Further, in this embodiment, the connecting pipes 7 and 8 also serve as supporting legs of the seat 4.

In the above configuration, the heating and cooling air sent through the air supply pipe 2 passes through the connecting pipe 7 to the seat 4.
It is sent to the outflow path 5 inside. The air that has entered the inflow path 5 cools or warms the seat 4 and is blown out toward the rear seat.

On the other hand, as above, the air was blown out from the front seat,
The air that cools or warms the atmosphere in front of the seat 4 is sucked into the inflow path 6 through the intake port 6a, collected into the air recovery pipe 3 via the connecting pipe 8, and collected into the heating and cooling source.

Therefore, as shown in FIGS. 2 and 3, in a large space building (a multipurpose dome in the figure) in which the above configuration is adopted for all seats, the heating and cooling air blown from the front seat 4 spreads to cover the entire rear seat 4, and a portion (50%)
position) is the inlet passage 6 of the rear seat 4.
The air is sucked into the air recovery pipe 3 through the air. Therefore, as shown in Fig. 3, the flow control valves 7a and 8a of all the seats 4 in the living areas (areas where people are present) A and B where heating and cooling in a large space building is desired should be opened appropriately. For example, in the accommodation areas A and B, a circulation flow of air conditioning air brought by the air supply pipe 2 and the air recovery pipe 3 is formed between the front and rear seats, respectively, and the total amount for all the seats 4... As a result, as shown in FIG. 3, air conditioning air barriers Ab and Bb covering the living areas A and B are formed. As a result, even if the entire inside of the building is not air-conditioned or heated, or is in a light heating and cooling state (low heating and cooling state), the living area A,
The heating and cooling of B will be performed reliably and adequately. Note that seats are not shown in FIG. 3 to avoid clutter.

As described above, according to the present invention, even if a large space building is an open space that cannot be heated and cooled, or a closed space that can be heated and cooled, or in a closed space, sufficient cooling and heating cannot be performed in terms of cost. Even in cases where people are present, cooling and heating of areas where people are present can be performed reliably, sufficiently, and with less heat loss. Also, if a person is in a certain seat 4, the flow control valve 7a located at the rear of the front seat 4
By adjusting the flow control valve 8a located in front of the seat 4, the temperature can be adjusted to the desired temperature without affecting the people in the surrounding seats 4. Furthermore, since the temperature of the seat 4 itself can be adjusted, comfort can be achieved. Furthermore, the air outlet 5a and the air intake port 6a,
In particular, if air guide vanes are provided in the air outlet 5a, the direction of the air circulating through each seat 4 can be changed. In addition, in the examples, a building to which the air conditioning system of the present invention is applied is shown that is provided with both a surrounding wall and a roof. It is suitable for applying the present invention because it is less susceptible to damage.

In the above embodiment, each seat was provided with two air outlets and two air intake ports, but there may be one, three or more, and the numbers of air outlets and intake ports do not have to match. . Furthermore, although the connecting pipes also serve as the legs of the seat, the legs of the seat may be provided separately from the connecting pipes to reduce the strength of the connecting pipes to the extent necessary for blowing air.

As explained above, the present invention installs an air supply pipe and an air recovery pipe for heating and cooling under the floor of a large space building, and provides an outflow path and an air recovery pipe in which each seat is provided with the air supply pipe and air recovery pipe. Connected to the inflow channel, at all seats in the building,
Air for heating and cooling is blown out from an outflow path of a certain seat toward neighboring seats, and air blown from other nearby seats is collected into the air recovery pipe through the inflow path of the certain seat. However, since the area around each seat can be selectively heated and cooled, it is possible to selectively heat and cool the area around each seat, regardless of whether the large building forms an open space or a closed space, and the number of people accommodated inside. To reliably, sufficiently, and economically perform heating and cooling of an area where people are present in a large space building, regardless of the amount of space. In particular, according to the present invention, since the air supply pipe and the air recovery pipe are equipped, and the air outlet is provided in the upper part of the backrest of the seat, and the air intake port is provided in the front end surface of the seat, the surrounding area of each seat is In other words, it is possible to form an air conditioning area only in a portion of a large space, thereby making it possible to significantly save energy. In this case, since the intake port is located below the air release port, air flows from above to below, which prevents warm air from escaping into a large space above, especially during heating operation. efficiently suppresses
Moreover, it can be recovered, and from this point of view as well, air conditioning efficiency can be increased and energy savings can be achieved. In addition, both sides of the connecting pipes are equipped with flow rate adjustment valves that can be operated from the outside, so not only can the occupants themselves directly control the air conditioning, but they can also open and close certain areas by opening and closing the flow rate adjustment valves. It is now possible to operate the system only in areas that require air conditioning, such as areas where people are seated, which also greatly contributes to energy savings by improving air conditioning efficiency.

Further, in the present invention, since the outflow passage and the inflow passage are formed in the seat, the seat itself is cooled from within during the cooling operation, and is warmed during the heating operation. Therefore, in addition to cooling or warming the surrounding air by the air conditioning, it is possible to directly cool or warm the seated person through the seat itself, and the air conditioning effect can be substantially improved accordingly.
