Description

Customized full-extraction floor air conditioning system capable of providing various differential pressures and air volumes

[0001] The present invention relates to the field of construction, and more particularly, to a full-extraction floor air conditioning system.

[0002] In the past, most buildings adopted ceiling-extracted air conditioning systems, which are configured to supply heated or cooled air to indoor spaces through air ducts in the ceiling.

[0003] In the case of cooling using a ceiling-extracting air conditioning system, there is a problem that cooling efficiency is reduced because the cool air coming from the ceiling must first cool the hot air above before it can reach the residential area below 1.8 m, and further, to the location below 1.2 m to 1.5 m where people are sitting.

[0004] To solve these problems, an underfloor air distribution system (UFAD) was developed.

[0005] It supplies heated or cooled air to the room through the indoor floor side, more specifically, through the underside of the access floor.

[0006] However, the existing floor air conditioning system has a problem in that it extracts air at a high speed (3-4 m / s) by installing floor exhaust vents (diffusers) at 4 m intervals on the floor, which causes airflow discomfort, and increases the concentration of fine dust in the living space by mixing it with indoor polluted air and spreading it, and if there is a virus infected person indoors, it quickly spreads it to the surroundings.

[0007] Additionally, when changing the layout, there is a great inconvenience of having to relocate the floor exhaust outlet.

[0008] The full-extraction floor air conditioning system is an improvement on these problems.

[0009] This has the advantage of not having an exhaust vent in the floor and having air drawn out at a low speed from the entire floor through the breathable double floor and floor finishing material, so there is no unpleasant airflow and the living area is always filled with fresh air.

[0010] Additionally, it is a replacement air conditioning system in which indoor polluted air rises in a laminar flow form without spreading to the surroundings and is exhausted from the ceiling.

[0011] This method can improve air quality by reducing the concentration of fine dust in residential areas and minimize the spread of the virus even if there are people infected indoors.

[0012] Additionally, since there is no floor exhaust outlet, there are no restrictions on changing the layout, making it convenient.

[0013]

[0014] Figure 1 illustrates a conventional front-extraction floor air conditioning system.

[0015] This supplies air from the floor space (10) toward the indoor space (20) through a plurality of supply holes (110) of the floor panel (100) installed between the floor space (10) and the indoor space (20) and a plurality of discharge holes (201) of the floor finishing material (200) installed on the upper part of the floor panel (100) by the differential pressure (pressure difference) between the floor space (10) and the indoor space (20).

[0016] As air is supplied to the floor space (10) by the fan (F) and the air is sucked into the ceiling space (30), a pressure difference occurs between the floor space (10) and the indoor space (20).

[0017] In addition, the full-extraction floor air conditioning system is configured to include an air supply unit (40), a temperature control unit (50), and a control unit.

[0018] The air supply unit (40) sucks in outside air and supplies air to the floor space (10).

[0019] The temperature control unit (50) is composed of a heating device or a cooling device and controls the temperature (T) of the air supplied to the floor space (10).

[0020] The larger the indoor space, the greater the differential pressure required, and the greater the indoor space's heat load (number of occupants, size and quantity of heat-generating devices, etc.), the greater the air volume required to provide a comfortable environment.

[0021]

[0022] Figures 2 to 4 relate to a conventional front-extraction floor air conditioning system. Figure 2 is a plan view of a floor panel (100), Figure 3 is a plan view of a floor finishing material (200), and Figure 4 is a plan view of a state in which a floor finishing material (200) is installed on a floor panel (100).

[0023] A floor finishing material (200) is fixedly installed on a floor panel (100) using an adhesive, and a plurality of supply holes (110) of the floor panel (100) and a plurality of discharge holes (201) of the floor finishing material (200) have a structure in which some are connected and some are not connected.

[0024] In Fig. 4, among the supply holes (110) of the floor panel (100), the black ones are connected to the discharge holes (201) of the floor finishing material (200), and the white ones are not connected.

[0025] These prior technologies had the following problems:

[0026] First, since the supply hole (110) of the floor panel (100) and the discharge hole (201) of the floor finishing material (200) have a uniform structure, it is impossible to provide various differential pressures and air volumes according to the size and heat load of the indoor space (20).

[0027] Second, the supply hole (110) of the floor panel (100) and the discharge hole (201) of the floor finishing material (200) are irregularly formed and often do not communicate with each other, making it difficult to control the air volume at a constant level and inefficient.

[0028] Third, even if the size of the indoor space (20) is constant, the heat load may change depending on changes in its purpose, changes in the number of people in the room, changes in the size and number of heating devices, etc., and since the floor finishing material (200) is fixed to the floor panel (100) using an adhesive, it is difficult to respond to changes in the heat load.

[0029] Fourth, when used for a long period of time, the adhesive components applied to the entire floor panel are continuously discharged into the indoor space together with the supplied air, thereby lowering the indoor air quality.

[0030] The present invention was developed to solve the above problems, and the purpose of the present invention is to provide a customized full-extraction floor air conditioning system capable of providing various differential pressures and air volumes according to the size and heat load of an indoor space, being efficient because the air volume can be adjusted at a constant level, easily responding to changes in heat load, and solving the problem of deterioration of indoor air quality due to adhesives.

[0031] In order to solve the above problem, the present invention is a customized front-extraction floor air conditioning system for supplying air from the floor space (10) toward the indoor space (20) through a plurality of supply holes (110) of a floor panel (100) installed between the floor space (10) and the indoor space (20) and a plurality of discharge holes (201) of a floor finishing material (200) installed on the upper part of the floor panel (100) by the differential pressure between the floor space (10) and the indoor space (20), and providing various differential pressures and air volumes according to the size and heat load of the indoor space (20), wherein the discharge holes (201) of the floor finishing material (200) are formed smaller than the supply holes (110) of the floor panel (100), and a plurality of them are gathered to form a discharge hole group (210), and each discharge hole group (210) is positioned on the upper part of each supply hole (110). A floor panel (100) and a floor finishing material (200) are installed, and the floor panel (100) is any one of a low-air volume floor panel (100a), a medium-air volume floor panel (100b), and a high-air volume floor panel (100c) having different numbers of the supply holes (110), and the floor finishing material (200) is any one of a low-air volume floor finishing material (200a) and a high-air volume floor finishing material (200b) having different discharge hole arrangement structures of the discharge hole group (210), and the discharge hole group (210) of the low-air volume floor finishing material (200a) is a single-line discharge hole group (210a) having a structure in which three or more of the discharge holes (201) are arranged in a row, and the discharge hole group (210) of the high-air volume floor finishing material (200b) is a single-line discharge hole group (210a) having a structure in which three or more of the discharge holes (201) are arranged in a row. A customized front exhaust floor air conditioning system is proposed, characterized by a polygonal exhaust hole group (210b) in which the exhaust holes (201) are arranged in a polygonal shape.

[0032] The above-mentioned floor panel (100) comprises a main body (120) in which a plurality of protrusions (121) and grooves (122) are formed in a radially symmetrical structure, and through holes (123) are formed on the upper ends of the protrusions (121); an upper plate (130) which is coupled to the upper portion of the main body (120) and has a square plane and a plurality of supply holes (110) formed in a radially symmetrical structure; and the supply holes (110) are arranged in a square grid structure and a radially symmetrical structure over the entire area of ​​the upper plate (130), and a joining hole (111) formed at equal intervals in the longitudinal and transverse directions. It is preferable that the non-bonded hole (112) is arranged in a radially symmetrical structure in a part of the upper plate (130), and that the bonding hole (111) of the upper plate (130) and the through hole (123) of the main body (120) are connected to each other by a burring press method.

[0033] It is preferable that the above upper plate (130) includes four supply parts (132) including a non-supply part (131) which is a “+” shaped area where the supply hole (110) is not formed; a coupling hole area (111a) which is a square shaped area where the coupling hole (111) is formed and which is formed on all sides of the non-supply part (131), and a non-coupling hole area (112a) which is a square shaped area where the non-coupling hole (112) is formed.

[0034] The above floor finishing material (200) is formed to have the same shape and size as the above top plate (130), and the top of the above floor finishing material (200) is located at the center of the above floor panel (100), and the center of the above floor finishing material (200) is located at the top of the above floor panel (100), so that a plurality of the above floor panels (100) and a plurality of the above floor finishing materials (200) are installed in an interlaced structure, and it is preferable that the edge of the above floor finishing material (200) is located at the non-supply portion (131) of the above top plate (130).

[0035] The above floor panel (100) is formed with the low air volume floor panel (100a) in which the non-joined hole area (112a) is formed smaller than the joint hole area (111a), and the non-joined holes (112) are formed in a larger number than the number of non-joined holes (112) of the low air volume floor panel (100a) so that a relatively larger air volume is supplied compared to the low air volume floor panel (100a), and the medium air volume floor panel (100b) in which the joint hole area (111a) and the non-joined hole area (112a) are formed in the same manner, and the non-joined holes (112) are formed in a larger number than the number of non-joined holes (112) of the medium air volume floor panel (100b) so that a relatively larger air volume is supplied compared to the medium air volume floor panel (100b), and the non-joined holes are formed in a larger number than the joint hole area (111a). It is preferable that the area (112a) be one of the high-volume floor panels (100c) formed in a large area.

[0036] The above low-volume floor panel (100a) is preferably formed such that the non-joint hole area (112a) is offset toward the center of the floor panel (100) among the joint hole areas (111a).

[0037] The high-volume floor panel (100c) includes an outer non-bonded hole area (112b) formed on the outside of the bonded hole area (111a) among the non-bonded hole areas (112a); and it is preferable that the outer non-bonded hole area (112b) is formed to be tilted inward from the vertex of the floor panel (100).

[0038] In order to prevent movement of the floor plate of the floor finishing material (200) installed on the upper surface of the floor panel (100) while allowing easy upward removal of the floor finishing material (200) from the floor panel (100), it is preferable that an adhesive portion (220) made of an adhesive material is formed on the lower surface of the floor plate of the floor finishing material (200).

[0039] It is preferable that the upper surface of the above floor panel (100) is formed of steel, and the adhesive portion (220) of the above floor finishing material (200) is formed of synthetic resin material.

[0068] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0069] As illustrated in FIG. 5 and below, the present invention relates to a front-exhaust floor air conditioning system that supplies air from a floor space (10) toward an indoor space (20) through a plurality of supply holes (110) of a floor panel (100) installed between a floor space (10) and an indoor space (20) and a plurality of discharge holes (201) of a floor finishing material (200) installed on the upper portion of the floor panel (100) by a pressure difference between the floor space (10) and the indoor space (20).

[0070] This has the characteristic of being a customized full-extraction floor air conditioning system to provide various differential pressures and air volumes depending on the size and heat load of the indoor space (20).

[0071] The discharge hole (201) of the floor finishing material (200) is formed smaller than the supply hole (110) of the floor panel (100), and multiple discharge holes are gathered to form a discharge hole group (210).

[0072] The floor panel (100) and floor finishing material (200) are installed so that each discharge hole group (210) is positioned above each supply hole (110).

[0073] The floor panel (100) is manufactured using materials such as steel, FSRC, wood core, calcium sulfate, etc., and one of a low air volume floor panel (100a), a medium air volume floor panel (100b), and a high air volume floor panel (100c) having different numbers of supply holes (110) is installed.

[0074] As the number of supply holes (110) increases, the wind volume becomes stronger, so the number of supply holes (110) is formed in the order of low wind volume floor panel (100a), medium wind volume floor panel (100b), and high wind volume floor panel (100c).

[0075] The floor finishing material (200) refers to carpet tiles, synthetic resin (PVC) tiles, etc., and either a low-airflow floor finishing material (200a) or a high-airflow floor finishing material (200b) having different discharge hole arrangement structures of the discharge hole group (210) is installed. (Figs. 7, 8)

[0076] On top of the supply hole (110) of the relatively large floor panel (100), a plurality of discharge holes (201) of the relatively small floor finishing material (200) are arranged. The plurality of discharge holes (201) are arranged to have a constant interval (same as the diameter of the discharge holes) from each other, so that some of the discharge holes (201) communicate with the supply hole (110) in their entirety, and some of the other discharge holes (201) communicate with the supply hole (110) in some areas.

[0077] When multiple discharge holes (201) are arranged in a row, the discharge hole (201) arranged in the center is connected to the supply hole (110) in its entirety, but only a very small area of ​​the discharge hole (201) arranged at the edge is connected to the supply hole (110), so a relatively small amount of air is supplied. (Fig. 7)

[0078] When a plurality of discharge holes (201) are arranged in a polygonal shape (triangle, square, etc.), most of the area of ​​all discharge holes (201) is connected to the supply hole (110), so a relatively large amount of air is supplied. (Fig. 8)

[0079] Accordingly, the discharge hole group (210) of the low-volume floor finishing material (200a) takes the structure of a row discharge hole group (210a), which is a structure in which three or more discharge holes (201) are arranged in a row.

[0080] The discharge hole group (210) of the high-volume floor finishing material (200b) has a structure of a polygonal discharge hole group (210b), which is a structure in which three or more discharge holes (201) are arranged in a polygonal shape.

[0081] Accordingly, even when the floor finishing material (200) is installed on the floor panel (100) having the same number of supply holes (110), the air volume can be adjusted to vary depending on whether the low-air volume floor finishing material (200a) or the high-air volume floor finishing material (200b) is installed.

[0082] Even if the size of the indoor space (20) is constant, the heat load may change depending on changes in its purpose, changes in the number of people in the room, changes in the size and number of heating devices, etc., but the system according to the present invention has the effect of being able to easily respond to changes in the heat load simply by replacing the floor finishing material (200).

[0083]

[0084] The construction method of the customized full-extraction floor air conditioning system according to the present invention is performed through the following processes.

[0085] An appropriate differential pressure is set according to the size of the indoor space (20), and an appropriate air volume is set according to the heat load that will occur in the indoor space (20).

[0086] In accordance with the above differential pressure and air volume, an appropriate combination of floor panels (100) and floor finishing materials (200) is selected from among low air volume floor panels (100a), medium air volume floor panels (100b), high air volume floor panels (100c), low air volume floor finishing materials (200a), and high air volume floor finishing materials (200b).

[0087] The selected floor panel (100) and floor finishing material (200) are constructed.

[0088]

[0089] The floor panel (100) is composed of a main body (120) and a top plate (130). (Fig. 6)

[0090] The main body (120) is formed with a radially symmetrical structure of a number of protrusions (121) and grooves (122), and a through hole (123) is formed at the top of the protrusion (121).

[0091] The top plate (130) is coupled to the upper part of the main body (120), and is formed with a square plane structure, and a plurality of supply holes (110) are formed with a radially symmetrical structure.

[0092] The supply hole (110) is composed of a coupling hole (111) and a non-coupling hole (112). (Fig. 5,9)

[0093] The joints (111) are arranged in a square grid structure and radially symmetrical structure over the entire area of ​​the upper plate (130), and are formed with equal spacing in the longitudinal and transverse directions. (Fig. 5)

[0094] The joint hole (111) of the top plate (130) and the through hole (123) of the main body (120) are connected to each other by a burring press method. (Fig. 6)

[0095] The joint structure of the above joint hole (111) and penetration hole (123) is directly related to the strength of the floor panel (100), and is therefore equally applied to all patterns of various supply holes (110) described below.

[0096] The non-bonded holes (112) are arranged in a radially symmetrical structure in a portion of the upper plate (130). Since this is not directly related to the strength of the floor panel (100), they are arranged in various patterns as described below to change the wind volume.

[0097] That is, the arrangement structure of the bonding holes (111) related to the strength of the floor panel (100) is fixed, and by changing the arrangement structure of the non-bonding holes (112), various air volume supply structures are formed.

[0098]

[0099] The top plate (130) consists of a non-supply section (131) and four supply sections (132). (Fig. 9)

[0100] The non-supply area (131) refers to a “+” shaped area where a supply hole (110) is not formed.

[0101] The supply section (132) refers to four areas formed on all sides of the non-supply section (131), and is composed of a bonding hole area (111a), which is a square-shaped area in which a bonding hole (111) is formed, and a non-bonding hole area (112a), which is a square-shaped area in which a non-bonding hole (112) is formed.

[0102] In the embodiment of Fig. 9, a square-shaped area in which nine coupling holes (111) are formed among one supply section (132) becomes a coupling hole area (111a), and this is also the same as the embodiments of Figs. 12 and 15.

[0103] In the embodiment of Fig. 9, a square-shaped area in which 32 non-bonded holes (112) are formed among one supply section (132) becomes a non-bonded hole area (112a).

[0104] However, since the bonding region (111a) and the non-bonding region (112a) are not completely distinct concepts, some regions may be formed to overlap each other.

[0105] In the embodiment of FIG. 9, the bonding hole area (111a) is larger than the non-bonding hole area (112a), and four bonding holes (111) are included within the non-bonding hole area (112a).

[0106] In the embodiment of Fig. 10, a square-shaped area in which 40 non-bonded holes (112) are formed among one supply section (132) becomes a non-bonded hole area (112a), and since 9 bonded holes (111) are included within the non-bonded hole area (112a), the non-bonded hole area (112a) and the bonded hole area (111a) appear as the same area.

[0107] In the embodiment of FIG. 11, a square-shaped area in which 48 non-bonded holes (112) are formed among one supply section (132) becomes a non-bonded hole area (112a), the non-bonded hole area (112a) is larger than the bonded hole area (111a), and 9 bonded holes (111) are included within the non-bonded hole area (112a).

[0108]

[0109] The floor finishing material (200) is formed to have the same shape (square) and size as the top plate (130).

[0110] A plurality of floor panels (100) and a plurality of floor finishing materials (200) are installed in an alternating structure so that the top of the floor finishing material (200) is located at the center of the floor panel (100), and the center of the floor finishing material (200) is located at the top of the floor panel (100). (Fig. 11)

[0111] Accordingly, since the edge of the floor finishing material (200) (area where the discharge hole (201) is not formed) is positioned in the non-supply portion (131) of the top plate (130) (area where the supply hole (110) is not formed), air can be prevented from being discharged through the gap between adjacently installed floor finishing materials (200).

[0112]

[0113] As described above, the floor panel (100) is installed with one of a low air volume floor panel (100a), a medium air volume floor panel (100b), and a high air volume floor panel (100c) having different numbers of supply holes (110).

[0114] The low-wind volume floor panel (100a) has a pattern in which the non-bonded area (112a) is formed smaller than the bonded area (111a). (Figs. 9, 11)

[0115] Since it is structurally disadvantageous if the non-bonded hole (112) is formed adjacent to the edge of the floor panel (100), it is preferable that the non-bonded hole (112) be formed adjacent to the center of the floor panel (100) if possible.

[0116] For this purpose, the non-bonded area (112a) is formed toward the center of the floor panel (100) among the bonded areas (111a). (Fig. 9)

[0117] The medium-air volume floor panel (100b) has a larger number of non-bonded holes (112) than the number of non-bonded holes (112) of the low-air volume floor panel (100a) so that a relatively larger amount of air is supplied compared to the low-air volume floor panel (100a), and also has a pattern in which the bonded hole area (111a) and the non-bonded hole area (112a) are formed in the same manner. (Figs. 12, 14)

[0118] The high-airflow floor panel (100c) has a pattern in which a larger number of non-bonded holes (112) are formed than the number of non-bonded holes (112) of the medium-airflow floor panel (100b) so that a relatively larger amount of air is supplied compared to the medium-airflow floor panel (100b), and the non-bonded hole area (112a) is formed larger than the bonded hole area (111a). (Figs. 15, 17)

[0119] Since the high-volume floor panel (100c) is formed with a non-bonded area (112a) larger than the bonded area (111a), an outer non-bonded area (112b) is formed on the outside of the bonded area (111a) among the non-bonded areas (112a). (Fig. 15)

[0120] As described above, it is structurally disadvantageous for the non-bonded hole (112) to be formed adjacent to the edge of the floor panel (100), but if the non-bonded hole (112) is formed on the inside of the bonded hole area (111a) (center side of the floor panel), there is a concern that air may be discharged through the gap between the adjacently installed floor finishing materials (200) as the non-bonded hole (112) is formed in the non-supply section (131) (area in the shape of the letter "+").

[0121] Accordingly, the outer non-bonded region (112b) is formed on the outer side of the bonded region (111a) among the non-bonded regions (112a), but it is preferable to form it so as to be tilted inward from the vertex of the floor panel (100), thereby minimizing the possibility of structural defects.

[0122]

[0123] As described above, the discharge hole (201) of the floor finishing material (200) is formed smaller than the supply hole (110) of the floor panel (100), and a plurality of them are gathered to form a discharge hole group (210).

[0124] The discharge hole group (210) of the floor finishing material (200) is formed to correspond to the pattern of various supply holes (110) of the low air volume floor panel (100a), the medium air volume floor panel (100b), and the high air volume floor panel (100c) (each discharge hole group (210) is positioned on the upper part of each supply hole (110)). (Figs. 10, 13, 16, 18, 20, 22)

[0125] In addition, the discharge hole group (210) of the low-volume floor finishing material (200a) takes the structure of a row discharge hole group (210a), which is a structure in which three or more discharge holes (201) are arranged in a row. (Figs. 10, 13, 16)

[0126] The discharge hole group (210) of the high-volume floor finishing material (200b) has a structure of a polygonal discharge hole group (210b), which is a structure in which three or more discharge holes (201) are arranged in a polygonal shape. (Figs. 18, 20, 22)

[0127] Accordingly, by combining a low air volume floor panel (100a), a medium air volume floor panel (100b), a high air volume floor panel (100c) and a low air volume floor finishing material (200a) (Figs. 11, 14, 17), or by combining a low air volume floor panel (100a), a medium air volume floor panel (100b), a high air volume floor panel (100c) and a high air volume floor finishing material (200b) (Figs. 19, 21, 23), it is possible to provide various air volumes suitable for the heat load of an indoor space while maintaining the structural stability of the floor panel (100).

[0128]

[0129] Figure 24 is a graph showing the relationship between differential pressure and air flow when various combinations of floor panels and floor finishing materials (A, B, C, D, E) are applied.

[0130] The above examples (A, B, C, D, E) are formed by a combination of the above-described floor panels and floor finishing materials.

[0131] In the case of a combination of a low-air volume floor panel (100a) and a low-air volume floor finishing material (200a) (A), the lowest air volume is generated at all differential pressures, and even when the differential pressure increases, the increase in air volume is the smallest.

[0132] Conversely, in the case of a combination of a high-airflow floor panel (100c) and a high-airflow floor finishing material (200b) (E), the highest airflow is generated at all differential pressures, and the increase in airflow is the greatest as the differential pressure increases.

[0133] That is, various combinations are required with respect to differential pressure and air volume suitable for the size and heat load of the indoor space (20), and the full-extraction floor air conditioning system according to the present invention can provide a combination of floor panels and floor finishing materials to meet these requirements.

[0134] For example, if the required differential pressure in an indoor space is 10pa and the air volume is 13CMH / ㎥, it is appropriate to install combination B.

[0135] If the required differential pressure in the indoor space is 15pa and the air volume is 24CMH / ㎥, it is appropriate to install the E combination.

[0136] If the required differential pressure in the indoor space is 25pa and the air volume is 30CMH / ㎥, it is appropriate to install the C combination.

[0137] In this way, the full-extraction floor air conditioning system according to the present invention has the effect of providing a differential pressure appropriate for the size of the indoor space (20) and the most appropriate combination of floor panels and floor finishing materials in accordance with the heat load generated in the indoor space (20).

[0138]

[0139] In order to prevent the movement (sliding) of the floor plate of the floor finishing material (200) installed on the upper surface of the floor panel (100) and to enable easy upward removal of the floor finishing material (200) from the floor panel (100), an adhesive portion (220) made of an adhesive material is formed on the lower surface of the floor plate of the floor finishing material (200). (Fig. 25)

[0140] When the upper surface of the floor panel (100) is formed of steel, the floor plate of the floor finishing material (200) is formed of PVC material, and the adhesive portion (220) of the floor finishing material (200) is formed of synthetic resin material (such as a composite of acrylic resin foam and urethane resin), the above-described effect can be obtained.

[0141]

[0142] The above is only a description of some of the preferred embodiments that can be implemented by the present invention, and as is well known, the scope of the present invention should not be construed as being limited to the above embodiments, and the technical idea of ​​the present invention described above and the technical idea that shares its basis are all included in the scope of the present invention.
