Description

Air Conditioning System for Buildings

The present invention relates to a building air conditioning system, and more particularly, to a building air conditioning system capable of efficiently cooling / heating a building having a high ceiling and having many heat sources near the ceiling.

In general, high-rise buildings, that is, high-rise buildings include broadcasting studios, cinemas, and performance halls.

In particular, in the case of a broadcasting studio, the ceiling of the general building is three stories high and the height of the ceiling is often about 11-13m, and even in low cases, the ceiling is installed about 7,5-8.5m at the height of the second floor of the general building. In addition, a broadcasting studio is provided with a catwalk under the ceiling, and many special lighting devices for broadcasting are installed under the catwalk. In addition, the horizontal unit may be installed at regular intervals below the catwalk.

The broadcast studio having such a structure is configured to cool / heat the inside of the broadcast studio by an air conditioning system. 1 is a conceptual diagram showing a broadcast studio 1 in which a building air conditioning system 10 according to the prior art is installed.

Referring to FIG. 1, the air conditioning system 10 according to the related art installed in the broadcasting studio 1 is installed in a separate space from the broadcasting studio 1, and is provided with an air conditioner 11 equipped with a cooling / heating device. , A plurality of nozzle diffusers 12 installed on the ceiling of the broadcast studio 1, and a duct 15 connecting the plurality of nozzle diffusers 12 and the air conditioner 11.

There is a problem that air circulation is not well achieved near the floor where people are active.

In order to facilitate air circulation, the speed of the air-conditioned air A discharged to the plurality of air supply ports 13 may be increased. In this way, if the speed of the air (A) is discharged, it is possible to supply air to the bottom surface, but the noise is increased. In general, since the broadcast studio 1 is sensitive to noise, it is also limited to increase the speed.

In addition, even when the air can be supplied at high speed, the broadcasting studio 1 is provided with a large number of broadcasting lights 5 in the catwalk (or grid) installed directly under the ceiling, so that the air There is interference and it does not feed smoothly to the floor. In particular, since the broadcast light has a large amount of heat, the cold air A discharged from the air supply port 13 during cooling is heated by the broadcast light so that it is not supplied to the floor while maintaining a cold state. Therefore, there is a problem in that the broadcast progress staff or staff members in the broadcast studio 2 should proceed while feeling uncomfortable.

Therefore, the development of the air conditioning system for buildings that can effectively coordinate the interior (2) of the broadcast studio (1) in order to give comfort to those working in the broadcast studio (1).

In addition, the building air conditioning system according to an embodiment of the present invention because the air for cooling / heating through a plurality of air supply vents installed on the inner side wall of the building and discharge the air inside the building through a plurality of exhaust vents installed on the ceiling It is efficient because air inside the building can circulate and cool / heat due to the convection phenomenon.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the building air conditioning system according to the present invention.

However, in the following description of the present invention, if it is determined that the detailed description of the related known functions or components may unnecessarily obscure the subject matter of the present invention, the detailed description and the detailed illustration will be omitted.

2 is a conceptual diagram illustrating a broadcasting studio that is an example of a building in which an air conditioning system for buildings according to an embodiment of the present invention is installed. 3 is a view showing the arrangement of a plurality of air supply of the air conditioning system for buildings according to an embodiment of the present invention installed on the inner side wall of the broadcast studio, Figure 4 is an embodiment of the present invention installed on the ceiling of the broadcast studio The figure which shows arrangement | positioning of several exhaust port of the air conditioning system for buildings by this.

2 to 4, the building air conditioning system 100 according to an embodiment of the present invention is an air conditioner 110, a plurality of air supply 111, a plurality of exhaust port 113, air supply duct ( 112, and exhaust duct 114.

The broadcasting studio 1 in which the building air conditioning system 100 according to an embodiment of the present invention is installed is installed at a height of approximately 2 to 3 floors of a general building. 2 schematically shows a broadcasting studio 1 installed at a height of three floors of a general building. Next to the broadcasting studio 1, a three-storey general building 3 may be installed. Each floor of the general building 3 may be provided with an office, a control room, a product preparation room and the like attached to the broadcasting studio 1. The office, control room, product preparation room, etc. may be configured to provide central air conditioning / heating by a separate air conditioning system (not shown) from the broadcast studio 1.

The air conditioner 110 is installed outside the building, that is, the broadcasting studio 1, and circulates the air in the broadcasting studio 2 to adjust the inside of the broadcasting studio 2 to maintain an appropriate temperature and humidity. Such an air conditioner 110 may include a cooling / heating device capable of cooling or heating air, and having an appropriate capacity according to the size of the broadcasting studio 1 and the cooling load of the inside of the broadcasting studio 2. Is installed. Since the structure and operation of the air conditioner 110 is the same as or similar to the air conditioner according to the prior art, a detailed illustration and description thereof will be omitted.

The broadcast studio 1 may be provided with many devices for broadcasting, in particular, a large amount of lighting device. Broadcast lighting apparatus is generally installed on a catwalk or grid spaced apart from the ceiling 8 of the broadcast studio (1). That is, the catwalk or grid functions as a support for fixing broadcast lighting. In FIG. 2, the part with the catwalk (or grid) and broadcasting lighting installed therein is indicated by a dotted line. That is, reference numeral 5 of FIG. 2 represents a catwalk and broadcast lighting installed therein. In addition, a horizontal (Horizont) (not shown) may be installed below the broadcasting light 5 at a predetermined distance.

In general, when calculating the cooling load, the external load (or structure load), which is a load by the building itself, the human load as the internal load, the load of equipment used inside the building, the external load invaded by outside air that invades the building, And the ventilation load, etc. should be taken into account. By the way. In the case of the broadcasting studio (1), since broadcast lighting and equipment have a large amount of heat generation, they occupy most of the cooling load. As an example, in the broadcasting studio 1 in which the building air conditioning system 100 according to the present embodiment is installed, the total cooling load is 338,098 Kcal / h, among which the cooling load of broadcasting lighting and equipment is 307,587 Kcal / h. to be.

The plurality of air supply 111 discharges air that is air-conditioned from the air conditioner 110, that is, air adjusted to an appropriate temperature and humidity to the inside 2 of the broadcasting studio 1, It is installed on the inner side wall 7. As shown in FIG. 3, the plurality of air supply 111 may be provided at a predetermined interval in a row on the side wall 7 at the same height H2 on the bottom surface 9 of the broadcast studio 1. At this time, the plurality of air supply 111 is preferably installed on the side wall (7) to be located under the broadcast light (5). In addition, when the horizontal agent is installed, the plurality of air supply ports 111 may be installed on the side wall 7 at a height corresponding to the space between the broadcast lighting 5 and the horizontal key. In addition, as shown in FIG. 5, the plurality of air supply 111 has four sidewalls of the broadcasting studio 1 having the same height at a constant height H2 at the bottom surface 9 of the broadcasting studio 1. It may be installed on the three side walls (7) of 7).

In order to increase the cooling efficiency of the broadcast studio 1, the installation heights H2 of the plurality of air supply ports 111 may be proportionally determined according to the height H1 of the ceiling 8 of the broadcast studio 1. That is, the height H2 from the bottom surface 9 of the broadcasting studio 1 to the plurality of air supply 111 with respect to the height H1 from the bottom surface 9 of the broadcasting studio 1 to the ceiling 8. ) May be set to 0.45 to 0.96, more preferably 0.5 to 0.65.

For example, when the ceiling height H1 of the broadcasting studio 1, that is, the height H1 from the floor surface 9 of the broadcasting studio 1 to the ceiling 8 is the third floor height of a typical building, that is, , About 13 m, the height H2 from the bottom surface 9 of the broadcasting studio 1 to the plurality of air supply 111 may be set to about 6 m to 12.5 m. At this time, it is more preferable that the height H2 from the bottom surface 9 of the broadcasting studio 1 to the plurality of air supply ports 111 is about 6.5 m to 8.5 m.

In the case of the present embodiment, when the plurality of air supply 111 is installed at the height of 7m, 8m, 12m from the bottom surface 9 through the computer fluid dynamics (CFD) analysis experiment as described later, the desired result is obtained, in particular It was confirmed that the most preferable results were obtained when installed at 7m and 8m height. If the installation height H2 of the plurality of air supply 111 is too high, the air A discharged from the plurality of air supply 111 interferes with the broadcast lighting, the catwalk 5, or the like installed near the ceiling 8. The discharged cooling air (A) is immediately heated to reduce the cooling efficiency, the discharged cooling air (A) is difficult to reach the bottom surface 9, the room temperature is too high, the possibility that the average temperature exceeds 25 ℃ It is not preferable because it is high.

In addition, if the installation height (H2) of the plurality of air supply 111 is too low, a space of 2m or less can be very low temperature, but can properly cool the broadcast lighting (5) or the like installed on the ceiling (8). Therefore, the average temperature of the whole broadcast studio interior 2 can be high, and it is not preferable because the air cooled can be directly discharged to the person working near the bottom surface 9 because it can be unpleasant.

As another example, although not shown, when the broadcast studio 1 is two stories high in a general building, that is, the height H1 from the bottom surface 9 of the broadcast studio 1 to the ceiling 8 is about eight. In the case of m, the height H2 from the bottom surface 9 of the broadcasting studio 1 to the plurality of air supply 111 may be set to about 3.6 m to 7.7 m. More preferably, the height H2 from the bottom surface 9 of the broadcasting studio 1 to the plurality of air supply ports 111 may be set to about 4.0 m to 5.2 m.

In addition, the plurality of air supply 111 may be inclined to eject the air (A) air-conditioning toward the bottom surface 9 of the broadcast studio (1). In this case, as shown in FIG. 2, each air supply 111 may discharge air A in a downward direction with an angle θ of the side wall 7 of the broadcasting studio 1 at about 40 to 50 degrees. Can be installed. Preferably, the air supply 111 is installed at an angle of about 45 degrees with respect to the side wall 7 of the broadcast studio 1.

The plurality of air supply 111 is in communication with the air conditioner 110 through the air supply duct 112 provided on the ceiling 8 and the side wall 7 of the broadcast studio 1. Therefore, the air conditioned by the air conditioner 110 is discharged into the interior 2 of the broadcast studio 1 through the plurality of air supply 111.

A diffuser that can be used as the air supply 111 can sufficiently secure the airflow reaching distance of the discharged air, and use a noise of 30 dB or less even when the air is discharged at high speed. Therefore, it is preferable to use a direct-flow nozzle diffuser which is discharged directly at neck wind speed. When such a nozzle diffuser is used as the air supply port 111, the noise becomes approximately 30 dB or less even when the neck wind speed of the discharged air is about 8 m / s. 6 shows an example of such a nozzle diffuser 111.

The plurality of exhaust ports 113 may be formed to discharge air in the broadcasting studio 2 to the air conditioner 110, and are installed on the ceiling 8 of the broadcasting studio 1. The plurality of exhaust ports 113 may be installed at regular intervals as shown in FIG. 4 so that the air in the broadcasting studio 2 may be efficiently sent to the air conditioner 110.

The plurality of exhaust ports 113 communicate with the air conditioner 110 through an exhaust duct 114 provided in the ceiling 8 of the broadcast studio 1. Therefore, the air drawn into the plurality of exhaust ports 114 is returned to the air conditioner 110 through the exhaust duct 114.

In addition, the ceiling 8 of the broadcasting studio 1 may be provided with a plurality of ventilation holes 115 for discharging the internal air of the broadcasting studio 1 to the outside atmosphere instead of the air conditioner 110. In general, the building is hermetically sealed and insulated for energy saving, so that the air circulates through the air conditioner 110 and the indoor space 2 and is not discharged to the outside or introduced into the outside air. Therefore, as the quality of indoor air deteriorates with time, it is necessary to discharge indoor air to the outside and supply fresh outside air. A plurality of ventilation openings 115 are used to discharge contaminated indoor air outside the building for this purpose. On the other hand, when the cooled indoor air is discharged to the outside, waste of energy is increased, so that a ventilation facility 116 equipped with an appropriate exhaust heat recovery device (not shown) may be installed. In the case of the present embodiment, when the ventilation fan (not shown) is operated, the outside air inlet of the air conditioner 110 is opened in conjunction with this, and is configured to introduce 20-30% of the outside air. At this time, the introduced outdoor air is formed to exchange heat with cold air of the room to be discharged. Therefore, the building air conditioning system 100 according to an embodiment of the present invention can supply uniform high quality fresh air without temperature / humidity fluctuations.

As shown in FIG. 5, the broadcasting studio 1 in which the building air conditioning system 100 according to the embodiment of the present invention is installed is provided in a plurality of side walls 7 of the three surfaces of the broadcasting studio 1. Cool air A is discharged from the air supply 111 toward the bottom surface 9, and the air B in the warmed broadcast studio 2 rises to raise the plurality of exhaust ports 113 installed in the ceiling 8. Return to the air conditioner 110 through). That is, the air inside the broadcast studio 2 circulates due to natural convection, thereby effectively cooling.

In addition, since the plurality of air supply ports 111 are provided under the broadcast light 5, the air A discharged from the plurality of air supply ports 111 interferes with or is heated by the broadcast light 5 or the catwalk. The cooling efficiency is increased because the liquid is discharged toward the bottom surface 9 of the broadcasting studio 1 without being supplied.

Computational Fluid Dynamics (CFD) analysis was performed to confirm the effect of the building air conditioning system 100 according to an embodiment of the present invention having the above structure.

This CFD analysis solves and analyzes fluid flow problems using finite volume techniques. When a cooling / heating facility is installed in a large space, a supercomputer is used to simulate the fluid-air interaction. By simplifying the equation from a number of assumptions, or by using a good supercomputer, simulations can provide results similar to the actual installation.

We used HIGH PERFORMANCE WORKSTATION from IBM in Korea. This workstation has a processing capacity of 100 teracrosses. In addition, the analysis conditions assume that the temperature of the air A discharged from the air supply port 111 is about 15 ° C., the air flow rate of the air supply port 111 is 22.8 CMM, and the total indoor load is 378.5 KW.
