Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for air conditioning a dome-shaped circular structure such as a multi-purpose stadium with a roof.

Conventionally, in the air conditioning of this type of structure, the position and quantity of the air outlet are determined by taking into consideration the reach distance and diffusion status of the conditioned air blown out from the outlet of the air conditioner. This has been done by locating air conditioners within the building so that they return to the same air conditioner.

Generally, air outlets are placed above the audience seats, and air inlets are placed below the seats, and air conditioning is performed by ducting to each outlet and air inlet.

Therefore, when trying to obtain a good airflow distribution, the number of air outlets and suction ports increases, and the length of the duct becomes long.

The present invention was proposed in view of the above circumstances, and involves distributing a plurality of air conditioners at predetermined intervals along the inner circumferential surface of a dome-shaped circular structure, so that all the air outlets of the air conditioners are connected to each other. The suction ports of the air conditioners adjacent to each other on the downstream side of each air conditioner are oriented in one direction, either clockwise or counterclockwise, and the suction ports of the air conditioners adjacent to each other on the upstream side of the air conditioners are The conditioned air blown out from the outlet of each air conditioner is placed in a position where it can be sucked in, and the conditioned air blown out from the outlet of each of the air conditioners is sucked through the inlet of the air conditioner adjacent to the downstream side of each air conditioner. An air conditioning method for a dome-shaped circular building characterized by forming a spiral airflow along the inner peripheral surface of the building, the purpose of which is to improve the air conditioning effect with less power. The object of the present invention is to provide an air conditioning method for a dome-shaped circular building.

In the present invention, as shown in the schematic diagram of FIG. For example, conditioned air blown out from the air outlet a1 located in the counterclockwise direction in the device a is sucked in through the suction port b2 of the adjacent air conditioner b, and then again into the air outlet located in the counterclockwise direction. The conditioned air blown out from the air conditioner b1 and thus blown out from the air outlet b1 is sucked into the suction port c2 of the adjacent air conditioner c, and thereafter in the same manner between the air conditioners a, b, c...n. Since the conditioned air is sent in sequence, the indoor conditioned air rotates in one direction, counterclockwise, creating a swirl. Due to the inertia of this vortex, the air is diffused with less power, and a good airflow distribution of the conditioned air is obtained, improving the air conditioning effect.

In addition, since conditioned air is sent sequentially between adjacent air conditioners, it is possible to install the air conditioner outlets and suction ports in close proximity to each other in a plan view, which reduces the need for large air conditioning ducts. Shortening is possible.

Furthermore, a part of the circulating air circulates inside the building while promoting the inertia of the vortex, rises, and is discharged from the exhaust port at the top of the building, effectively eliminating dirty air from the upper part of the building and improving the air conditioning effect. It is intended to improve Further, according to the present invention, since the airflow distribution is obtained using inertial force in this way, the air blown from the air outlet from each air conditioner does not collide with each other, and the air blown from each air conditioner reaches the The distance can be increased, and at the same time, the inertial force of the vortex is generated, which reduces the power of the blower.

Furthermore, since the spiral conditioned air is an airflow that moves along the inner surface of the outer wall of the building, the wind speed at the lower center of the building is significantly reduced, and the wind has almost no effect on the competitions in the areas where various competitions are held. .

Note that by making the air blown from the air conditioner into an intermittent wind, the speed of the swirling flow of conditioned air can be controlled and the temperature difference blown out can be increased, so comfort can be increased with a small air volume. It becomes possible.

The illustrated embodiment in which the present invention is applied to a multipurpose stadium with a roof will be described below.

1 is a dome-shaped circular building that constitutes a multi-purpose stadium with a roof, and seats are provided along the inner circumference of the building, and the center area surrounded by the seats forms the stadium 3, as shown in the figure. In this embodiment, the bleachers are comprised of a first floor grandstand 2A and a second floor grandstand 2B.

Conditioned air blow-off units 3 are arranged at predetermined intervals on a concentric circle with the building 1 at the top of each of the spectator seats 2A and 2B, and the conditioned air A is supplied from the blow-off ports 3a of each unit 3. The air is intermittently blown out, and the air outlet 3a is oriented counterclockwise, and the air is sucked in from the conditioned air inlet 3b of the adjacent unit on the downstream side. , thus a swirling flow of conditioned air moving along the building 1 is created. A portion of the air outlet 3a is oriented in a direction different from that of the spiral flow forming air outlet, so as to locally empty the viewing seats near the unit 3.

In the figure, 4 is a gas absorption cold/hot water generator installed at the bottom of the bleachers in the structure 1, and the cold/hot water generated in the aircraft 4 is transferred to a cold/hot water pump 5.
Accordingly, the air is supplied to an air handling unit 9 for supplying conditioned air to each unit 3 via the supply header 6, the lettuce header 7, and piping 8, 8 connected to each header. Furthermore, a retan duct 10 is connected to the unit 9 for recirculating the conditioned air blown from the conditioned air blowing unit 3 adjacent to the upstream side. In the figure, reference numeral 11 denotes a duct that connects the air handling unit 9 to the conditioned air blowing unit 3.

Further, 12 is connected to each of the headers 6 and 7, and 1
Mobile seating 2C located in front of floor seating 2A
The floor heating pipe 13 is a pipe branched out from the pipe 8 and connected to the fan coil unit 14 of the box bleachers 2D above the first floor bleachers 2A,
The unit 14 individually controls the temperature of the box seats 2D.

Others 15 are the air handling units 9;
Outdoor air intake louver for the machine room equipped with
Numerals 6 and 17 are louvers for sucking outside air into the upper part of the second floor bleachers 2B and the roof truss, respectively, and 18 is an exhaust louver for removing stagnant air from the upper part of the dome.

Therefore, the conditioned air A blown out counterclockwise from the outlet 3a of each conditioned air blowing unit 3 is as follows:
The air is sucked into the duct 10 from the tip suction port 3b of the air duct 10, and the air handling unit 9,
The air is supplied to the conditioned air blowing unit 3 adjacent to each unit 3 through the duct 11, and
The conditioned air is blown out from the outlet 3a of the unit 3, and the conditioned air is thus sent sequentially to each unit 3, so the indoor air rotates in one direction, creating a swirling flow, and its inertia causes it to flow with less power. Air is diffused, good airflow distribution is obtained, and efficient air conditioning effects are obtained. In addition, since the conditioned air is sent sequentially in this manner, the outlet 3a and the inlet 3b can be provided at points close to each other in a plane, making it possible to significantly shorten the air conditioning duct, and furthermore, the swirling flow can be reduced. is the airflow along the perimeter of the building, so
The wind speed in the stadium 3 at the center of the lower part of the building is extremely low, and the influence of the wind on the competition is small.

Note that by making the air blown from the conditioned air blowing unit 3 into an intermittent air flow, the speed of the swirling flow can be controlled and the blowing temperature difference can be increased.
Comfort can be increased with a small air volume.
