Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically, to a hot water module frame for a dual-supply air conditioning and floor heating unit, and a dual-supply air conditioning and floor heating unit using the hot water module frame. Background Technology

[0002] Dual-supply air conditioning and floor heating units include an air conditioning module and a hot water module. The traditional layout is that the hot water module is below and the air conditioning module is above. The hot water module is generally equipped with an expansion tank, heat exchanger, water pump, electronic expansion valve, and inlet and outlet water ports. The air conditioning module is generally equipped with a heat exchanger module, necessary partitions, electrical box module, and compressor module, etc.

[0003] Since dual-supply air conditioning and floor heating units integrate air conditioning and hot water functions, the number of functional components is relatively large. Furthermore, due to the limited installation space currently reserved for the outdoor unit of dual-supply air conditioning and floor heating units, how to make the functional components compact and reduce the size of the outdoor unit to facilitate installation and maintenance is a problem that needs continuous improvement in this technical field.

[0004] Existing technology discloses an air conditioning and floor heating unit, in which an air conditioning module and a floor heating module are arranged vertically. The floor heating module at the bottom uses a frame including a base, on which a first support plate, a second support plate, and a third support plate are spaced apart along its circumference. The first, second, and third support plates provide the main support for the shell to facilitate the installation of other components. The base of the air conditioning module is fixedly connected to the top of the three support plates. Because the floor heating module uses a three-support plate structure to support the upper air conditioning module, it results in excessive obstruction of the floor heating module's frame. This not only excessively encroaches on the installation space of the hot water module, leading to a complex internal structure of the hot water module, but also reduces the operating space during maintenance, making it difficult to repair individual components inside the hot water module. Summary of the Invention

[0005] One of the objectives of this invention is to design a hot water module frame and a dual-supply air conditioning and floor heating unit to solve the problems of complex hot water module structure and difficult maintenance in existing air conditioning and floor heating units.

[0006] This invention is achieved through the following technical solution:

[0007] The present invention provides a hot water module frame, including a hot water module chassis and a plurality of support frames arranged sequentially along the longitudinal direction of the hot water module chassis; the support frame includes a crossbeam and columns, the crossbeam extends laterally along the hot water module chassis, and the columns are respectively provided at both ends of the crossbeam, the top end of the column is fixedly connected to the crossbeam, and the bottom end of the column is fixedly connected to the top surface of the hot water module chassis.

[0008] When the above-described structure is adopted, multiple support frames are arranged longitudinally on the hot water module chassis of the hot water module frame. These support frames serve as the supporting structure for the air conditioning module. Since the support frames are a beam-column structure, compared to the support plates used in existing technologies, they reduce obstruction and space occupation within the hot water module frame, providing more space for maintenance and installation. This not only facilitates after-sales maintenance and reduces maintenance costs, but also allows for more flexible arrangement of components within the hot water module frame, reducing installation difficulty and simplifying the layout, thereby lowering maintenance complexity and production costs.

[0009] To further improve the implementation of the present invention, the following structure is specifically adopted: the top surfaces of both ends of the crossbeam are respectively provided with upwardly protruding parts, and a recessed clearance groove is formed between the two protruding parts.

[0010] To further improve the implementation of the present invention, the following structure is specifically adopted: a groove is formed at the bottom of the protrusion, and the top of the column is inserted into the groove of the protrusion on the corresponding side.

[0011] To further improve the implementation of this invention, the following structure is specifically adopted: the top of the column and the protrusion are detachably connected by horizontally arranged screws.

[0012] To further improve the implementation of this invention, the following structural arrangement is adopted: the column is provided with a first screw hole extending laterally; the column is provided with a second screw hole extending longitudinally. At least one side of the column in the longitudinal direction is provided with a connecting plate extending longitudinally outward from the column, and the connecting plate is provided with a third screw hole for mounting a panel.

[0013] The present invention also provides a dual-supply air conditioning and floor heating unit, including a hot water module and an air conditioning module. The hot water module includes the aforementioned hot water module frame, and the air conditioning module chassis is fixedly connected to the top of the crossbeam of the hot water module frame.

[0014] To further improve the implementation of this invention, the following structural arrangement is adopted: the hot water module includes an expansion tank, a water pump, and a hot water module heat exchanger disposed within the hot water module frame. The expansion tank and the water pump are positioned on opposite sides of the longitudinal direction of the middle of the three support frames. The inlet and outlet of the hot water module are located at one end of its longitudinal direction.

[0015] To further improve the implementation of this invention, the following structural arrangement is adopted: the hot water module frame has three support frames. Of the three support frames, the middle one is positioned below the estimated longitudinal position of the air conditioning module's center of gravity.

[0016] The estimated longitudinal position of the center of gravity is calculated using the corner of the air conditioning module as the center and a plane coordinate system with the horizontal axis of the hot water module as the X-axis and the vertical axis of the hot water module as the Y-axis as the reference, according to the following formula:

[0017]

[0018] Where M is the total weight of the air conditioning module; m i This refers to the weight of each sub-module within the air conditioning module; y L is the Y-axis distance from the centroid of the submodule to the center of the planar coordinate system; y It is the estimated longitudinal position of the centroid.

[0019] To further improve the implementation of the present invention, the following structure is specifically adopted: among the three support frames, the top of the crossbeam of the middle support frame is provided with a support member, and the top of the support member is fixedly connected to the chassis of the air conditioning module.

[0020] To further improve the present invention, the following structural arrangement is adopted: the support member is positioned below the estimated lateral position of the center of gravity of the air conditioning module, and the estimated lateral position of the center of gravity is calculated using the planar coordinate system as a reference according to the following formula:

[0021]

[0022] Among them, l x L is the distance along the X-axis from the centroid of the submodule to the center of the planar coordinate system; x It is the estimated lateral position of the center of gravity.

[0023] To further improve the implementation of this invention, the following structural arrangement is adopted: the sub-module includes a two-phase module, a partition, an electrical box module, and a compressor module. The center of gravity of the sub-module is set at its central position.

[0024] To further improve the implementation of the present invention, the following configuration structure is adopted: of the three support frames, the two outer support frames are respectively located below the positions where the two heat exchanger modules and the compressor modules are located in the air conditioning module.

[0025] The present invention has the following advantages and beneficial effects:

[0026] In this invention, multiple support frames are longitudinally arranged on the hot water module chassis of the hot water module frame, serving as a support structure to support the air conditioning module. Because the support frames are beam-column structures, they offer better support compared to the support plates used in existing technologies. This not only reduces the amount of sheet metal used in the structure but also minimizes obstruction and space occupation within the hot water module frame, providing more space for maintenance and installation. This facilitates after-sales maintenance, reduces maintenance costs, and allows for more flexible arrangement of components within the hot water module frame, simplifying component installation and resulting in a more streamlined structure, thereby reducing maintenance difficulty and production costs.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Example 1:

[0046] A hot water module frame, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is specifically configured with the following structure:

[0047] In this embodiment, the hot water module frame serves as the installation foundation for the hot water module 01 of the dual-supply air conditioning and floor heating unit, and as the supporting structure for the air conditioning module 02.

[0048] like Figure 1 As shown, the hot water module frame includes a hot water module chassis 1 and multiple support frames 2. The hot water module chassis 1 is horizontally positioned, with a support leg connected to its bottom surface. In the figure, its longer side in the left-right direction is its longitudinal side, and its shorter side in the front-back direction is its transverse side.

[0049] All support frames 2 are sequentially arranged along the longitudinal direction of the hot water module chassis 1. Each support frame 2 is a beam-column structure, comprising a horizontally arranged beam 21 and a vertically arranged column 22. Both the beam 21 and the column 22 are U-shaped channel sheet metal parts. The beam 21 extends laterally along the hot water module chassis 1, with its slot facing downwards. A column 22 is located at each end of the beam 21, with its slot facing outwards in the lateral direction of the hot water module frame. The top of the column 22 extends into the slot of the beam 21 and is fixed to each other with screws, forming a portal frame. The bottom of the column 22 is supported on the top surface of the hot water module chassis 1 by outward-facing horizontal flanges and is fixedly connected with screws.

[0050] Since the crossbeam 21 is a component that directly contacts and is welded to the bottom surface of the air conditioning module chassis 7 of the air conditioning module 02, it needs to be positioned using different positioning protrusions and molding on the air conditioning module chassis 7. Therefore, the top surfaces of both ends of the crossbeam 21 are respectively formed with upward-facing protrusions 211, and a recessed clearance groove is naturally formed between the two protrusions 211 to avoid the air conditioning module chassis 7. At the same time, in order to facilitate the assembly of the crossbeam 21 and the air conditioning module chassis 7, the top surface of the protrusion 211 is provided with positioning holes 212 that match the positioning protrusions on the air conditioning module chassis 7. The bottom of the protrusion 211 naturally forms a groove, and the top of the column 22 is provided with a downward-facing flange that is inserted into the groove of the corresponding side of the protrusion 211. The top of the column 22 has a downward-facing flange, and the end of the protrusion 211 is provided with two fourth screw holes 225. The downward-facing flange of the column 22 and the end of the protrusion 211 are detachably fixedly connected by two horizontally arranged screws inserted into the fourth screw holes 225. The crossbeam 21 is fixed to the column 22 by two horizontal screws, which can increase the structural strength of the support frame 2.

[0051] In addition to its supporting function, the support frame 2 also serves to install other functional components and modules. Therefore, the web of the column 22 is provided with a first screw hole 221 extending laterally, the wing plate of the column 22 is provided with a second screw hole 222 extending longitudinally, and at least one wing plate on the longitudinal direction of the column 22 is provided with a connecting plate 223 formed by a flange extending longitudinally outward from the column 22. The connecting plate 223 is provided with a third screw hole 224, which is mainly used to install the panel of the dual-supply air conditioning and floor heating unit.

[0052] In this embodiment, the number of support frames 2 is determined according to the structure of the dual-supply air conditioning and floor heating unit used. Generally, three are set, but four or more can also be set.

[0053] In this embodiment, multiple support frames 2 are arranged longitudinally on the hot water module chassis 1 of the hot water module frame, and the support frames 2 serve as a support structure to support the air conditioning module. Since the support frames are a beam-column structure, they offer better support compared to the support plates used in the prior art. This not only reduces the amount of sheet metal used in the structure but also reduces obstruction and space occupation inside the hot water module frame, providing more space for maintenance and installation. This facilitates after-sales maintenance, reduces maintenance costs, and allows for more flexible arrangement of components inside the hot water module frame, reducing installation difficulty and simplifying the layout structure, thereby reducing maintenance difficulty and production costs. The top and bottom of the column 22 are detachably connected to the beam 21 and the hot water module chassis 1, respectively, and the column 22 can be removed when needed to expand the maintenance space.

[0054] Example 2:

[0055] This embodiment further provides a dual-supply air conditioning and floor heating unit based on the above embodiments, specifically adopting the following configuration structure:

[0056] In this embodiment, the dual-supply air conditioning and floor heating unit includes a hot water module 01 and an air conditioning module 02. The functional components of the hot water module 01 and the air conditioning module 02 are all configured according to the prior art.

[0057] like Figure 2 As shown, the hot water module 01 includes the hot water module frame as in Embodiment 1, and an expansion tank 3, a water pump 4, a hot water module heat exchanger 5, an electronic expansion valve, and inlet / outlet ports 6, etc., disposed within the hot water module frame. The hot water module frame has three support frames 2. These three support frames 2 divide the hot water module frame into two longitudinal installation spaces. The larger space is used to install the expansion tank 3, and the smaller space is used to install the water pump 4. The expansion tank 3 and the water pump 4 are positioned on either side of the middle support frame 2 along the longitudinal direction, thus rationally dividing the components. The inlet / outlet ports 6 of the hot water module 01 are located at one end of the hot water module frame along the longitudinal direction, and the mounting bracket for the inlet / outlet ports 6 is connected to the second screw hole 222 of the column 22 at that end.

[0058] The air conditioning module 02 includes an air conditioning module chassis 7, two-phase modules (evaporator and condenser modules), a partition, an electrical box module, a compressor module, etc. The air conditioning module chassis 7 is positioned by engaging with the protrusion 211 on the crossbeam 21 of the support frame 2 through a convex bulge, so as to be placed on the top of the protrusion 211. The air conditioning module chassis 7 and the protrusion 211 are fixed by welding.

[0059] The positions of the three support frames 2 are designed to ensure stable support for the air conditioning module 02. The specific positions of the support frames 2 can be determined using the following methods.

[0060] Of the three support frames 2, the middle support frame 2 is positioned below the estimated longitudinal position of the center of gravity of the air conditioning module 02. For example... Figure 3 As shown, the estimated longitudinal position of the center of gravity is centered on the lower left corner of the air conditioning module 02, and with a plane coordinate system using the horizontal axis of the hot water module 01 as the X-axis and the vertical axis of the hot water module 01 as the Y-axis as the reference, it is calculated according to the following formula:

[0061]

[0062] Where M is the total weight of air conditioning module 02; m i This refers to the weight of each sub-module in air conditioning module 02. A sub-module is a uniformly weighted component obtained from weight simplification within air conditioning module 02, including the heat exchanger module, partition, electrical box module, and compressor module. Since the sub-module is a uniformly weighted component, its center of gravity can be approximately set as its geometric center for ease of calculation. y It is the Y-axis distance from the centroid of the submodule to the center of the planar coordinate system; L y It is to estimate the longitudinal position of the center of gravity.

[0063] After estimating the position of the center of gravity on the Y-axis, the middle support frame 2 is positioned at the corresponding position on the Y-axis and then fixed to the hot water module chassis 1.

[0064] To prevent the dual-supply air conditioning and floor heating unit from tilting and becoming unstable due to the support frame 2 being biased to one side, the two support frames 2 located on the outside are respectively set below the position where the two heat exchanger modules are set and below the position where the compressor module is set in the air conditioning module 02.

[0065] Example 3:

[0066] This embodiment is a further optimization based on the above embodiments, and specifically adopts the following configuration structure:

[0067] In this embodiment, considering that the position of the crossbeam 21 of the middle support frame 2 will interfere with the two components in the air conditioning module 02, causing the weld between the protrusion 211 of the crossbeam 21 and the chassis 7 of the air conditioning module to cause wear on the copper pipes of the two components, the protrusion 211 on the crossbeam 21 of the middle support frame 2 is not fixed by welding to the chassis 7 of the air conditioning module. Instead, a support member 8 is set in the middle section of the crossbeam 21 and the support member 8 is fixed by welding to the chassis 7 of the air conditioning module.

[0068] Specifically, such as Figure 2 and Figure 3As shown, the support member 8 is a small sheet metal part, which is fixedly connected to the top surface of the crossbeam 21 by screws. The support member 8 and the protrusion 211 together support the air conditioning module chassis 7. The support member 8 is welded to the air conditioning module chassis 7 instead of the protrusion 211.

[0069] To ensure the centrally located support frame 2 can better bear the load and improve the stability of the air conditioning module 02, the support member 8 is positioned below the estimated lateral position of the center of gravity of the air conditioning module 02. The estimated lateral position of the center of gravity is calculated using a plane coordinate system and the following formula:

[0070]

[0071] Among them, l x L is the distance along the X-axis from the centroid of the submodule to the center of the planar coordinate system. x It is to estimate the lateral position of the center of gravity.

[0072] In this invention, the hot water module 01 of the dual-supply air conditioning and floor heating unit uses three support frames 2 to support and position the air conditioning module 02. The crossbeams 21 and columns 22 of the support frames 2 are made of channel-shaped sheet metal parts with a width between 40-50mm. Compared to the nearly 1000mm width of typical dual-supply air conditioning and floor heating units, this provides ample installation space for the hot water module 01. In case of damage to components inside the hot water module 01 due to special circumstances, the bottom hot water module 01 can be repaired without damaging the upper part of the air conditioning module 02. When repairing in a confined space, the columns 22 of the middle support frame 2 can be temporarily removed from the crossbeams 21 and the hot water module 01 to further increase the repair space and facilitate the replacement of damaged parts. The middle support frame 2 is located below the estimated center of gravity of the air conditioning module 02 in the longitudinal direction, and the support member 8 is located below the estimated center of gravity of the air conditioning module 02 in the lateral direction, which allows for a more accurate location of the center of gravity of the air conditioning module 02 and provides stable support for it.

[0073] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
