Description

Air conditioning system for air dome

The present invention relates to an air dome, and more particularly, since the air pressurizing unit and the air conditioning unit for injecting air into the air dome are integrally formed and connected in parallel to the air dome, the air pressurizing unit and the air conditioning unit can be used. The present invention relates to an air conditioning system for an air dome, which is advantageous in maintenance and has good operating reliability.

An air dome is a dome structure that forms an indoor space using air pressure. It does not have pillars or girders inside, so it has a very large indoor space. For example, it is used as an indoor sports facility, a large performance hall, an exhibition hall, or various warehouses. Air domes have much lower construction costs than ordinary buildings, are simple to install and dismantle, and have their own safety and durability.

In general, the air dome is formed by floating the outer envelope material by fixing the edge of the outer envelope material made of fibers to the ground and then pressurizing and blowing air into the outer envelope material. Of course, the structure can be stably maintained only if the injected air is maintained inside the air dome.

However, the air dome is not a closed chamber in which the indoor space is completely physically blocked, but because the air escapes while a person enters and exits through the door, and the use of the air is prolonged, the air leaks somewhere. The pressurized ventilation should be done.

1 is a block diagram illustrating a conventional air dome 11 together with a pressurizer 13 and an air conditioner 15.

As shown, the air dome 11 provides the interior space (11a) formed by the edge portion is fixed to the ground and has a plurality of doors (11b) on the side. In addition, the air dome 11 is connected to the pressurizer 13 and the air conditioner 15 as a means for injecting air into the indoor space (11a).

Pressurizer 13 serves to continuously press the air to maintain the shape of the air dome in the interior space (11a). The air supplied from the pressurizer 13 inflates the air dome 11 and maintains a taut state. In addition, the air conditioner 15 is to harmonize the air in the indoor space 11a. For example, the air conditioner serves to adjust or clean the temperature and humidity of the room.

By the way, the air dome 11, the pressurizer 13 and the air conditioner (15) is connected in series has the disadvantage that maintenance is cumbersome. That is, since the air discharged from the pressurizer 13 passes through the air conditioner 15 and fills the indoor space 11a, for example, when the pressurizer 13 fails, the air conditioner 15 independently has a sufficient amount. It cannot supply air. This is because the air conditioner 15 receives the air supplied from the pressurizer 13 at first and heats or cools it and supplies it.

In addition, Figure 4 is a view showing a connection structure between the air conditioning system and the air dome, Figure 5 is a view showing the internal structure of the air conditioning system.

As shown, the air conditioning system 20 for an air dome according to the present embodiment includes a case 21, a pressurizing unit 30, an air conditioning unit 50, a bypass damper 41, and a control unit 25. do.

The case 21 takes the form of a cube as shown in FIG. 3 and has an air supply duct 35, a ventilation duct 57, and a main duct 59 at the bottom thereof. The air supply duct 35 is connected to the air supply passage 23a of the underground buried pipe 23, the ventilation duct 57 is connected to the ventilation passage 23b, and the main duct 59 is connected to the main passage 23c.

The underground buried pipe 23 is made of concrete and is buried in the ground between the case 21 and the air dome 11. In some cases, instead of the concrete underground buried pipe, the air supply passage 23a, the ventilation duct 57 and the main duct 59 itself may be extended to be connected to the air dome 11.

The case 21 is a container for accommodating the pressing unit 30 and the air conditioning unit 50, and has a plurality of inspection doors and a control unit 25 on the side wall. Since the pressing section 30 and the air conditioning section 50 are incorporated in one case, the overall size of the system is compact. The control unit 25 is a part operated by the manager, and controls the pressing unit 30, the air conditioning unit 50, and the bypass damper 41 to be described later.

In addition, the inside of the case 21 is partitioned into the first space 20a and the second space 20b by the partition wall 20c, and the bypass damper 41 is mounted on the partition wall 20c. The bypass damper 41 is controlled to open and close by the controller 25. When the bypass damper 41 is opened, the first space 20a and the second space 20b communicate with each other. When the bypass damper 41 is closed, the first space 20a and the second space 20b are completely blocked. do.

The pressurization part 30 includes a first external air damper 31, an air filter 32, a pressurizing blower 33, an air supply duct 35, and an air supply damper 34.

The first outside air damper 31 is installed on one wall surface of the case 21 and introduces outside air into the first space 20a or blocks the introduction of outside air. The first external air damper 31 is also controlled by the controller 25. When the first outside air damper 31 is opened, outside air may flow into the first space 20a, and when closed, the inflow of outside air is blocked. As long as this function can be performed, the type or structure of the first external air damper 31 may vary.

The air filter 32 is installed between the first outside air damper 31 and the pressurized blower 33 to filter the air flowing into the first space and directed toward the pressurized blower 33.

Pressurized blower 33 serves to press air into the interior space (11a) of the air dome (11). The reason for injecting air is to maintain the shape of the air dome 11. The pressurized blower 33 operates in a state where the first outdoor air damper 31 and the air supply damper 34 are opened and the bypass damper 41 is closed. Air generated in the pressure blower 33 is blown into the air dome 11 through the air supply damper 34, the air supply duct 35, and the air supply passage 23a. The air supply damper 34 is operated by the control unit 25 as opening and closing means provided at the bottom of the first space 20a.

The air conditioning unit 50 includes a second external air damper 51, a ventilation damper 56, an air filter 52, a cooling coil 53, a heating coil 54, a humidifier 55, and an air blower 58. And a main duct 59.

As shown in FIG. 3, the second air damper 51 is disposed on the front surface of the case 21 and opens and closes the second space 20b. When the second outdoor air damper 51 is opened, the outdoor air flows into the second space 20b, and the introduction of the outdoor air is stopped when the second air damper 51 is closed. Operation control of the second external air damper 51 is also performed by the controller 25.

The ventilation damper 56 opens and closes the ventilation duct 57 as a damper provided at the bottom of the second space 20b. The ventilation duct 57 is a duct that guides the air inside the air dome to the second space. If the ventilation duct 57 is blocked, air does not flow.

The air filter 52 filters the air introduced through the second external air damper 51 or the ventilation damper 56. The kind of the air filter 52 is the same as the air filter 32 of the pressurization part.

The cooling coil 53, the heating coil 54, and the humidifier 55 are general, and serve to cool, heat, or humidify the air to be supplied to the air dome 11. The air filter 52, the cooling coil 53, the heating coil 54, and the humidifier 55 may maintain the indoor space 11a of the air dome 11 in a more comfortable state.

The air conditioner blower 58 supplies the air dome which is suitably harmonized inside the second space 20b. The air pumped by the air conditioning blower 58 is blown through the main duct 59 and the main passage 23c to the indoor space of the air dome.

Reference numerals 61 and 63 in FIG. 2 denote grills. One grill 61 is mounted at the opening of the air supply passage 23a and the ventilation passage 23b that is open to the bottom of the indoor space 11a, and the other grill 63 is opened to the bottom of the indoor space. The opening of the passage 23c is covered.

6 to 8 are schematic diagrams for explaining the operation of the air conditioning system for an air dome according to an embodiment of the present invention. For convenience, the dampers that are blocked are marked with an X in the rectangle.

6A and 6B are plan and front schematic views showing a state in which only the pressing unit 30 is operated without operating the air conditioning unit 50. This is a case where air conditioning in the air dome 11 is unnecessary while maintaining the air conditioning unit 50.

As shown, the bypass damper 41, the second external air damper 51, and the ventilation damper 56 are blocked, and the first outdoor air damper 31 and the air supply damper 34 are opened. When the pressure blower 33 is operated in this state, outside air flows into the first space 20a and is then filtered and then supplied to the air dome through the air supply passage 23a.

7A and 7B illustrate a case in which both the pressing unit 30 and the air conditioning unit 50 are operated. As shown, the air supply damper 34 and the second external air damper 51 are blocked, and the first outdoor air damper 31, the bypass damper 41, and the ventilation damper 56 are opened.

When the pressurized blower 33 and the air conditioning blower 58 are operated in the above state, outside air flows into the second space 20b through the first outside air damper 31 and the bypass damper 41, and then the main duct. It is supplied to the air dome 11 through the 59 and the main passage 23c. At the same time, the air inside the air dome 11 flows into the second space 20b through the ventilation passage 23b and the ventilation damper 56 and circulates.

8A and 8B are schematic plan and front views in which only the air conditioning unit 50 is operated with the pressing unit 30 stopped. As shown, while maintaining the pressing unit 30, it is possible to maintain the shape of the air dome 11 using only the air conditioning unit (50). In other words, the air conditioning unit 50 may replace the function of the pressing unit 30.

In this case, the first external air damper 31, the air supply damper 34, and the bypass damper 41 are blocked, and the second external air damper 51 and the ventilation damper 56 are opened. When the air conditioning blower 58 provided in the second space 20b is operated, outside air flows into the second space 20b through the second outside air damper 51, and at the same time, the air dome 11 Air also moves to the second space 20b through the ventilation damper 56. The air introduced into the second space 20b is supplied to the air dome 11 through the main duct 59 after filtering and temperature and humidity control. The air supplied serves to maintain the shape of the air dome.

9 is a view for explaining a modification of the air conditioning system for an air dome according to an embodiment of the present invention.

Hereinafter, the same reference numerals as the above reference numerals denote the same members having the same function.

Referring to the drawings, it is understood that the sensing target 73 is fixed to the center of the ceiling surface of the air dome 11, and a plurality of altitude sensors 71, a controller 75, and a timer 77 are disposed on the ground. Can be.

The altitude sensor 71 is installed at a plurality of points where the sensing target 73 is visible on the bottom of the air dome 11 and detects the height of the sensing target 73 in real time. That is to detect the height and height change of the sensing target 73 relative to the ground. For example, when the air in the indoor space 11a is removed, the altitude of the sensing target 73 is lowered, but the altitude is detected to be lowered.

The controller 75 is connected to each altitude sensor 71 and receives the detection contents of the altitude sensor. In addition, the timer 77 measures the altitude duration after the change in the altitude change of the sensing target 73 and transmits it to the controller. For example, if the altitude of the sensing target 73, which was 20 meters, is lowered to 19 meters, the time is lowered to 19 meters.

The controller 75 determines that the air in the indoor space 11a is removed when the time when the altitude is lowered becomes longer than the set time, for example, 1 minute, and operates the hot air fan 83. The controller 75 is also connected to the controller 25 described above.

The hot air fan 83 serves to eject the air supplied from the outside to the indoor space 11a. Since the air blown out from the hot air blower 83 is heated, it immediately rises to support the air dome. An installation pit 81 is provided at the bottom of the indoor space 11a to install the hot air fan 83. The installation pit 81 is a space for receiving the hot air blower 83 and is covered with a grill (not shown).

In addition, the outside air inlet 11 is provided with an external air inlet pipe 85. The external air inlet pipe 85 extends vertically as if it is a chimney and has a lower end fixed in the ground and is connected to the installation pit 81 through the first induction tube 86. The first induction tube 86 is provided with a valve 86a and an air pump 86b.

The valve 86a is a check valve opened and closed by the controller 75 and prevents the air inside the installation pit 81 from flowing back to the outside air inlet pipe 85. In addition, the air pump 86b serves to suck the outside air and supply it to the installation pit 81. The air pump 86b is also controlled by the controller 75.

In addition, the underground buried pipe 23 and the installation pit 81 are connected to the second induction tube (87). Air inside the underground buried pipe can be guided to the installation feet (81). It is preferable to be connected to the main passage 23c among the air supply passage 23a, the ventilation passage 23b, and the main passage 23c provided in the underground buried pipe.

The valve 87a and the air pump 87b are also installed in the second induction tube 87. The valve 87a prevents the air inside the installation pit 81 from flowing back to the main passage 23c, and the air pump 87b pumps the air inside the main passage 23c to the installation pit 81.

The hot air fan 83 receives a sufficient amount of air introduced into the installation pit 81, heats it, and blows it into the indoor space 11a to support the air dome 11 as described above. While the hot air fan 83 supports the air dome, the pressurizing unit 30 is operated to form a sufficient pressure in the indoor space 11a, and then the hot air fan 83 is stopped.

As mentioned above, although this invention was demonstrated in detail through the specific Example, this invention is not limited to the said Example, A various deformation | transformation is possible for a person with ordinary knowledge within the scope of the technical idea of this invention.
