Abstract
Description
Technical Field
[0001] The utility model relates to the field of heating and ventilation, and in particular to a heating and ventilation plate system. Background Art
[0002] In order to adjust the room temperature, a combination of air conditioning and heating is usually used: air conditioning is used to cool the room when the weather is hot, and floor heating or radiators are used to heat the room when the weather is cold.
[0003] Floor heating is more energy-efficient than convection heating using radiators and comes in various forms, including water heating and electric heating. Existing water-heated floor heating systems are installed within a concrete layer. Typically, a 30-50mm thick layer of insulating foam is laid on the ground. A reflective layer of aluminum foil is then placed over the foam. The heating pipes are then coiled around the foil reflective layer according to the inlet and return water requirements and secured with U-shaped plastic clips. The heating is then filled and leveled with 30-35mm of concrete or cement mortar. Finally, a decorative layer, such as wood flooring or tiles, is laid over the filling layer.
[0004] This solution has several prominent problems: First, the construction is relatively complicated, requiring both plumbing and building construction. Second, it consumes a lot of materials. When using concrete or cement mortar to cover and fill floor heating pipes, a lot of cement, gravel, sand and other building materials are needed. Third, leakage inspection is very difficult. Since the floor heating pipes are sealed in the filling layer, if a leak occurs, it is difficult to detect. Even if it is discovered, the filling layer needs to be chiseled open to repair it. Fourth, it has a significant impact on the height of the building. Since the thickness of the insulation foam plastic is 30-50mm and the thickness of the concrete is 30-35mm, the combined thickness of the two is 60-85mm, which is particularly significant for buildings with smaller heights. Fifth, the heat dissipation is slow and the thermal efficiency is low. Since the water pipes are buried in the concrete at intervals, it takes a long time for the heat to be transferred to the concrete between the water pipes before it can be released to the ground. There are also problems with uneven heat distribution and large heat loss. Utility Model Content
[0005] The purpose of the utility model is to provide a HVAC panel system to solve the problems in the prior art.
[0006] The utility model is realized by the following technical solutions: a HVAC panel system, wherein the panel is long and has a plurality of rectangular water passage cavities and fixing holes penetrating therein along the length direction; a docking assembly is provided between two adjacent panels along the length direction, and a water distribution assembly is provided at the end of the panel;
[0007] The docking assembly includes a docking piece, which is provided with a docking cavity corresponding to the rectangular water cavity and a screw hole corresponding to the fixing hole; a sealing gasket is provided between the docking piece and the plate; and a docking pipe, which is provided with sealing rings at both ends and is respectively inserted into the docking cavities of two adjacent docking pieces;
[0008] The water distribution assembly includes a water distribution piece, a water distribution cavity is provided in the water distribution piece, a sealing kit is provided on the water distribution piece to match the water pipe, and the water distribution cavity is connected to the rectangular water cavity and the sealing kit on the plate.
[0009] Furthermore, it also includes a butt joint fixing plate, and two adjacent butt joint members are connected and fixed by screws through two screw holes on the butt joint fixing plate.

[0012] The beneficial effects of the present invention are as follows: the present invention has a simple structure, can be disassembled for maintenance and relocated, and the overall height after completion is about 30 mm, which can effectively reduce the impact on the building's floor height or space.

DETAILED DESCRIPTION

[0019] The docking assembly includes a docking piece 3, which has a docking cavity corresponding to the rectangular water cavity and screw holes corresponding to the fixing holes; a sealing gasket 2 is provided between the docking piece and the plate; and a docking pipe 7, which has sealing rings 8 at both ends. The two ends of the docking pipe are respectively inserted into the docking cavities of two adjacent docking pieces and sealed by the sealing rings.
[0020] The water distribution assembly includes a water distribution part 9, which is provided with a water distribution cavity. Sealing kits 10 that match the connecting water pipe are provided at both ends of the water distribution part. The water distribution cavity communicates with the rectangular water cavity and the sealing kit on the plate.
[0021] Preferably, a butt joint fixing piece 6 is further included, and two screw holes are provided on the butt joint fixing piece, and two adjacent butt joint pieces are connected and fixed by screws.
[0022] Preferably, the fixing hole on the plate is columnar with a hole in the middle to facilitate cooperation with the screw.
[0023] Preferably, it also includes a pan head self-tapping screw 4, which passes through the screw hole of the water distribution component and cooperates with the fixing hole of the plate, thereby assembling and fixing the water distribution component to the end of the water-passing plate; and then using a connecting water pipe to connect the two sets of water distribution components equipped with water-passing plates.
[0024] This utility model is a plastic panel profile designed for radiant heating and cooling on floors and walls. It features multiple internal water channels. Once laid on the floor and fitted with sealing components, hot water circulates through the panels to provide heat and cool the room, or cool the room to provide cooling. The panels can also be installed on walls and ceilings, providing both decorative, thermal, and sound insulation benefits.
[0025] In the structure of the utility model, the plate-type profiles are connected in parallel horizontally and extended in any direction to realize the sealed pressure-resistant water circulation, as follows:
[0026] A. When extending the butt joint: a. Cut the plate profile 1 horizontally at a 90° angle perpendicular to the forward direction. b. Place the sealing gasket on the fixed-length water-flow plate butt joint 3. c. Use M4*30 pan-head flat-tail self-tapping screws to secure the sealing gasket and fixed-length water-flow plate butt joint to the neat horizontal end face of the plate profile. d. Install the sealing ring on the fixed-length water-flow plate butt joint pipe and insert it into the circular holes on the two fixed-length water-flow plates that need to be butted together. e. Place the fixed-length water-flow plate butt joint fixing plate in a fixed position on the two butted joint parts and secure it with M2.3*8 countersunk flat-tail self-tapping screws.
[0027] B. For horizontal parallel connection: a. Cut the panel profile neatly at a 90° angle perpendicular to the longitudinal direction. b. Place the sealing gasket on the water distribution panel. c. Use M4*30 pan head flat tail self-tapping screws to secure the sealing gasket and water distribution panel to the neat horizontal end surface of the panel profile. d. Insert the connecting water pipe into the two water distribution panel components equipped with the water pipe sealing kit to complete the horizontal parallel connection.
[0028] C. After assembling several water-permeable panels through the above-mentioned splicing method, the selected decorative surface layer can be laid on them.
[0029] This solution differs fundamentally from the principle of thermal radiation conduction of fluids within traditional cylindrical and plate-type water pipes laid on the ground. The temperature of the fluid within traditional cylindrical pipes is conducted 360 degrees by radiation, and its efficiency decreases as the upward radiation angle increases. Cylindrical pipes cannot be laid without spacing, so the heat and cold energy that is not radiated upward must be conducted away through the filler within the spacing of the cylindrical pipes. As a result, most of the energy is lost and not fully utilized. In contrast, the temperature of the fluid within the water pipes in this solution can conduct away almost 100% of the heat and cold energy by radiation. This is because the rectangular channels within the plate-type water pipes allow the fluid to form a nearly seamless, parallel, and 10mm vertically distanced flat layer, allowing for unimpeded and efficient upward radiation of heat and cold energy. This is one of the reasons why plate-type water pipes laid on the ground can save 50% of energy compared to cylindrical water pipes through radiation conduction. In addition, when used in ground radiation cooling and heating, the cooling and thermal resistance is very small. The water layer circulating in the water plate is 6~10mm away from the ground surface (related to the thickness of the ground decoration material), and the difference between the water flow temperature and the ground surface temperature is about 4℃. Therefore, low-temperature water (30~35℃) can be used for ground radiation heating in winter, and high-temperature water (29~21℃) can be used for ground radiation cooling in summer.
