Technical Field
[0001] This utility model relates to the field of building decoration construction technology, and in particular to a fresh air supply and return design structure based on a residential radiant air conditioning system. Background Technology
[0002] In residential building design, according to the building control indicators specified in Table 4.0.2 of the "Urban Residential Area Planning and Design Standard" (GB50180-2018), the maximum height control value for residential buildings is 80 meters.
[0003] Residential buildings equipped with capillary radiant air conditioning systems and centralized fresh air conditioning systems offer advantages such as "constant temperature," "constant humidity," "constant oxygen," "constant cleanliness," and "constant quietness." These features constitute a high level of comfort in high-quality residences and enjoy high market acceptance. Existing capillary radiant air conditioning systems with centralized fresh air conditioning systems generally employ floor-mounted air supply designs. Floor-mounted air supply ducts must consider the weight of furniture and people, and must not create a "soft" feeling. Floor-mounted air supply ducts typically use 85×45mm ducts, thus requiring a 140mm-150mm installation space to be reserved above the floor for floor-mounted air supply. This has a significant impact on the floor height of residences with limited space.
[0004] For residential buildings using floor-mounted ventilation, the floor height is typically 3.05m-3.15m, and the net indoor height is generally 2.60m. If the ventilation system uses a top-mounted supply and return design, the floor height can be designed to be 2.95m while maintaining a net indoor height of 2.60m. For residential buildings with a height limit of 80m, a top-mounted supply and return design allows for the construction of an additional floor compared to a floor-mounted ventilation design, increasing the building's floor area ratio and bringing greater economic benefits. Utility Model Content
[0005] The purpose of this invention is to provide a top-mounted supply and return air design structure for a residential radiant air conditioning system. This design allows the centralized fresh air conditioning system to adopt a top-mounted supply and return air design. The supply and return air ducts of the centralized fresh air conditioning system are integrated with the capillary ceiling structure of the capillary radiant air conditioning system, controlling the height occupied by the ceiling and reducing the height of the reserved space on the ground. While ensuring the net height of the residential interior, the floor height of the residential building can be appropriately reduced. For residential buildings with a height limit of 80m, an additional floor can be built compared to the floor supply air design, increasing the building's floor area ratio. This provides technical support for increasing the total building area on limited land and brings significant economic benefits.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A ceiling-mounted air supply and return design structure based on a residential radiant air conditioning system includes a suspended ceiling structure consisting of a keel structure layer, gypsum board, capillary network, gypsum mortar layer, and putty latex paint layer. The keel structure layer is connected to the bottom of the floor slab. The gypsum board is placed at the bottom of the keel structure layer. The capillary network is laid at the bottom of the gypsum board. The gypsum mortar layer is placed at the bottom of the gypsum board to cover the capillary network. The putty latex paint layer is placed at the bottom of the gypsum mortar layer. The height of the suspended ceiling structure is no more than 100mm.
[0008] A capillary tube is laid inside the keel structure layer between the gypsum board and the floor slab. The capillary tubes in the capillary network pass through the gypsum board and are connected to the capillary tube. A fresh air duct is laid inside the keel structure layer between the gypsum board and the floor slab. The fresh air duct includes a supply air duct and a return air duct. Supply air outlets and return air outlets are respectively provided on the supply air duct and the return air duct. Holes for installing supply air outlets and return air outlets are provided in the gypsum board. The capillary network is laid to avoid the holes provided in the gypsum board.
[0009] As a further preferred embodiment of this utility model, the keel structure layer adopts a clip-on light steel keel, which includes a main keel and a secondary keel. The main keel is connected to the floor slab by expansion bolts, and the secondary keel is snap-on connected to the main keel.
[0010] To reduce the ceiling height occupied by the suspended ceiling, the secondary keel is disconnected when the capillary main pipe and the secondary keel intersect; this method avoids the increase in ceiling height caused by the stacking of the capillary main pipe and the secondary keel.
[0011] Furthermore, the spacing between the secondary keels is no greater than 400mm.
[0012] To reduce the ceiling height occupied by the suspended ceiling, the secondary keel is disconnected when the fresh air duct intersects with it; this method avoids the increase in ceiling height caused by the stacking of the fresh air duct and the secondary keel.
[0013] As a further preferred embodiment of this utility model, the fresh air duct is ceiling-mounted, the cross-sectional dimensions of the fresh air duct are 132×30mm, and the outside of the fresh air duct is wrapped with 10-15mm thick rubber and plastic insulation material.
[0014] As a further preferred embodiment of this invention, the capillaries in the capillary network are made of PPR pipes with a diameter of 5 mm.
[0015] As a further preferred embodiment of this invention, a 7-10mm gap is reserved where the capillaries in the capillary network pass through the gypsum board.
[0016] Furthermore, reinforcing keels are installed on both sides of the gap, with the distance between the reinforcing keels and the gap not exceeding 100mm, and the reinforcing keels are connected to the keel structural layer.
[0017] As a further preferred embodiment of this utility model, a glass fiber mesh is provided in the gypsum mortar layer, and the capillary mesh is located between the gypsum board and the glass fiber mesh.
[0018] The advantages of this utility model are:
[0019] (1) When installing a capillary radiant air conditioning system + a centralized fresh air conditioning system, the centralized fresh air conditioning system adopts a top supply and return air design, which ensures the comfort of the living environment while the indoor air conditioning unit does not occupy the indoor space. Since the floor supply air duct does not need to be installed, the floor structure is simpler, which improves the freedom of interior decoration design. At the same time, the air conditioning system with independent temperature and humidity control is not affected.
[0020] (2) The supply and return air ducts of the centralized fresh air air conditioning system are integrated with the capillary ceiling structure of the capillary radiant air conditioning system to control the height occupied by the ceiling and reduce the height of the reserved space on the ground. While ensuring the net height of the residential building, the floor height of the residential building can be appropriately reduced. For residential buildings with a height limit of 80m, the supply and return air design with top air supply and top return air can be adopted, which can build one more floor than the floor air supply design, increase the building's volume ratio, provide technical support for increasing the total building area on limited land, and bring greater economic benefits.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1As shown, this embodiment is a ceiling-mounted supply and return air design structure based on a residential radiant air conditioning system. It includes a ceiling structure consisting of a keel structure layer, gypsum board 1, capillary network 2, gypsum mortar layer 3, and putty / latex paint layer 4. The keel structure layer is connected to the bottom of the floor slab 5. Gypsum board 1 is placed at the bottom of the keel structure layer and is a 12mm thick waterproof gypsum board. The capillary network 2 is laid at the bottom of the gypsum board 1, and the capillary tubes in the capillary network 2 are made of 5mm diameter PPR pipes. The gypsum mortar layer 3 is placed at the bottom of the gypsum board 1 to cover the capillary network 2. A fiberglass mesh 6 is installed in the gypsum mortar layer 3. 2 is located between gypsum board 1 and fiberglass mesh 6. The thickness of gypsum mortar layer 3 is 15mm. In actual application, the thickness of gypsum mortar layer 3 is controlled between 12-15mm. Putty latex paint layer 4 is set at the bottom of gypsum mortar layer 3. In this embodiment, the height of the ceiling structure is 100mm. In actual application, the height of the ceiling structure is controlled within 100mm, that is, the height of the ceiling structure is not greater than 100mm. In this embodiment, the height of the ceiling structure refers to the thickness of the ceiling structure, that is, the sum of the thicknesses of the keel structure layer, gypsum board 1, gypsum mortar layer 3 (including capillary mesh 2 and fiberglass mesh 6), and putty latex paint layer 4.
[0026] A capillary tube 7 is laid inside the keel structure layer between gypsum board 1 and floor slab 5. The capillary tube 7 is made of De20. The capillary tubes in the capillary network 2 pass through gypsum board 1 and are connected to the capillary tube 7. A fresh air duct 8 is laid inside the keel structure layer between gypsum board 1 and floor slab 5. The fresh air duct 8 includes a supply air duct and a return air duct. Supply air outlets and return air outlets are respectively set on the supply air duct and the return air duct. Holes for installing supply air outlets and return air outlets are set on gypsum board 1. When laying the capillary network 2, the holes set on the gypsum board 1 are avoided. The supply air duct and the return air duct are laid far apart from each other, so that the supply air outlets and return air outlets are far apart from each other. The fresh air duct 8 shown in the attached figure is the supply air duct.
[0027] In this embodiment, the keel structure layer adopts a clip-type light steel keel, which includes a main keel 11 and a secondary keel 12. The main keel 11 is connected to the floor slab 5 by expansion bolts, and the secondary keel 12 is connected to the main keel 11 by a snap-fit. The spacing of the secondary keels 12 is no more than 400mm, and the load-bearing capacity of the secondary keel 12 is greater than 30kg / m.
[0028] To reduce the ceiling height occupied by the suspended ceiling, the secondary keel 12 is disconnected when the capillary main pipe 7 and the secondary keel 12 intersect; this method avoids the increase in ceiling height caused by the stacking of the capillary main pipe 7 and the secondary keel 12.
[0029] To reduce the ceiling height occupied by the suspended ceiling, the secondary keel 12 is disconnected when the fresh air duct 8 intersects with it; this method avoids the increase in ceiling height caused by the stacking of the fresh air duct 8 and the secondary keel 12.
[0030] In this embodiment, the fresh air duct 8 is installed in the ceiling. The cross-sectional dimensions of the fresh air duct 8 are 132×30mm. The fresh air duct 8 is wrapped with a 15mm thick rubber and plastic insulation material 9. Of course, in actual applications, the fresh air duct 8 can also be wrapped with a 10mm or 12mm thick rubber and plastic insulation material 9.
[0031] In practical applications, a 7-10mm gap is reserved where the capillaries in the capillary network 2 pass through the gypsum board 1. Reinforcing keels are set on both sides of the gap, with the distance between the reinforcing keels and the gap not exceeding 100mm. The reinforcing keels are connected to the keel structural layer.
[0032] In this embodiment, the ceiling height is controlled at 100mm, so that the ceiling occupies 100mm of the indoor top space. Since no floor air supply ducts need to be installed, there is no need to reserve space for floor air supply duct installation on the ground. Therefore, the height of the reserved space on the ground can be reduced. Under the premise of ensuring an indoor net height of 2.60m, the residential floor height can be designed to be 2.95m. For residential buildings with a height limit of 80m, the supply and return air design with top air supply and top return air can be used to build one more floor than the floor air supply design, thereby increasing the building's floor area ratio and bringing greater economic benefits.
[0033] This utility model has the following advantages:
[0034] (1) When installing a capillary radiant air conditioning system + a centralized fresh air conditioning system, the centralized fresh air conditioning system adopts a top supply and return air design, which ensures the comfort of the living environment while the indoor air conditioning unit does not occupy the indoor space. Since the floor supply air duct does not need to be installed, the floor structure is simpler, which improves the freedom of interior decoration design. At the same time, the air conditioning system with independent temperature and humidity control is not affected.
[0035] (2) The supply and return air ducts of the centralized fresh air air conditioning system are integrated with the capillary ceiling structure of the capillary radiant air conditioning system to control the height occupied by the ceiling and reduce the height of the reserved space on the ground. While ensuring the net height of the residential building, the floor height of the residential building can be appropriately reduced. For residential buildings with a height limit of 80m, the supply and return air design with top air supply and top return air can be adopted, which can build one more floor than the floor air supply design, increase the building's volume ratio, provide technical support for increasing the total building area on limited land, and bring greater economic benefits.
