[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0038] Combination Figure 1-4As shown, this embodiment of the present disclosure provides a mid-way heating and ventilation system (HVAC) supplementary heating device, including: a housing 100, a solar vacuum tube 200, and a mixing component 300. The housing 100 is provided with a first chamber 101 and a second chamber 102 that can be connected to the heating pipe; the solar vacuum tube 200 is disposed at the top of the housing 100, and one end of the solar vacuum tube 200 is connected to the first chamber 101; the mixing component 300 is disposed in the second chamber 102 of the housing 100, and the mixing component 300 is connected to the first chamber 101 to accelerate the flow of circulating water in the first chamber 101.
[0039] The HVAC mid-circuit supplemental heating device provided in this embodiment connects the heating pipe to the first chamber 101, allowing circulating water in the heating pipe to circulate between the heating pipe and the first chamber 101. The first chamber 101 is connected to the solar vacuum tube 200, allowing the circulating water in the first chamber 101 to be heated by sunlight, increasing the temperature of the circulating water at the heating terminal without requiring additional energy consumption, resulting in low heating costs. The mixing component 300 is connected to the first chamber 101, accelerating the flow of circulating water within the first chamber 101 and reducing the temperature difference between different areas of the circulating water within the first chamber 101.
[0040] It is understandable that the solar vacuum tube 200 is a well-known and conventional technology in the field of science.
[0041] Optionally, multiple solar vacuum tubes 200 are provided, with one end of each solar vacuum tube 200 connected to the first chamber 101. In this way, the number of solar vacuum tubes 200 is relatively large, and multiple solar vacuum tubes 200 convert solar energy into heat energy under the sun's irradiation, increasing the temperature of the circulating water at the heating terminal, and the heating speed is relatively high, resulting in a relatively good heating effect.
[0042] Specifically, the solar vacuum tube 200 has nine tubes.
[0043] Combination Figure 3 As shown, optionally, a partition 110 is fixedly provided inside the housing 100, dividing the space inside the housing 100 into a first chamber 101 and a second chamber 102. In this way, the space inside the housing 100 is divided by the partition 110, preventing the first chamber 101 and the second chamber 102 from communicating, and the partition 110 provides support for the mixing assembly 300, resulting in relatively high stability.
[0044] Optionally, the mixing component 300 includes: a first fixed pipe 310, a first expansion bag 320, and a squeezing member 330. One end of the first fixed pipe 310 is connected to the first chamber 101, and the first fixed pipe 310 is fixedly connected to the housing 100; the first expansion bag 320 is disposed in the second chamber 102, and the other end of the first expansion bag 320 is connected to the first fixed pipe 310; the squeezing member 330 is disposed in the second chamber 102, and the squeezing member 330 can abut against and squeeze the first expansion bag 320. In this way, the circulating water in the first chamber 101 can flow into the first expansion bag 320 through the first fixed pipe 310, and the first expansion bag 320 will then expand. The squeezing member 330 can squeeze the first expansion bag 320, so that the circulating water in the first expansion bag 320 is re-sprayed into the first chamber 101 through the first fixed pipe 310, which accelerates the flow of circulating water in the first chamber 101, and accelerates the mixing of circulating water in different areas, thereby reducing the temperature difference.
[0045] Understandably, the first expansion bag 320 can absorb water a second time after being sprayed with water, which can also accelerate the flow of circulating water in the first chamber 101.
[0046] Optionally, a first side-flow pipe 340 communicating with the first chamber 101 is provided on the side wall of the first fixed pipe 310, and the other end of the first side-flow pipe 340 extends into the first chamber 101. In this way, when the first expansion bag 320 is squeezed, part of the circulating water in the first fixed pipe 310 flows into the first chamber 101 along the first side-flow pipe 340, and the water flow sprayed from the first side-flow pipe 340 is perpendicular to the water flow sprayed from the first fixed pipe 310, which makes the disorder and mixing effect of the water flow better, accelerates the mixing of circulating water in different areas, and thus reduces the temperature difference.
[0047] Optionally, second fixed pipes 350 are respectively provided on both sides of the first fixed pipe 310. One end of each second fixed pipe 350 is connected to the first chamber 101 and fixedly connected to the housing 100. The other end of each second fixed pipe 350 is connected to a second expansion bag 360. The extruder 330 can abut against and extrude the second expansion bag 360. In this way, the structure and function of the second fixed pipe 350 and the second expansion bag 360 are similar. The extruder 330 can extrude the second expansion bag 360, so that the circulating water in the second expansion bag 360 is re-injected into the first chamber 101 through the second fixed pipe 350, which accelerates the flow of circulating water in the first chamber 101 and accelerates the mixing of circulating water in different areas, thereby reducing the temperature difference. Moreover, the first fixed pipe 310 and the second fixed pipe 350 work together to cover a wider area and achieve better results.
[0048] Optionally, the first expansion bag 320 and / or the second expansion bag 360 are made of an elastic material, preferably rubber. This allows both the first expansion bag 320 and / or the second expansion bag 360 to deform elastically, resulting in a relatively high water storage capacity, relatively large water absorption and spray volume, and relatively good mixing effect of the circulating water. The first expansion bag and / or the second expansion bag 360 made of rubber material also offer high durability.
[0049] Optionally, the diameter of the first fixing pipe 310 is larger than the diameter of the second fixing pipe 350; the diameter of the first expansion bag 320 is larger than the diameter of the first fixing pipe 310; and the diameter of the second expansion bag 360 is larger than the diameter of the second fixing pipe 350. In this way, since the first fixing pipe 310 is located between the second fixing pipes 350, its position is more central, and its diameter is larger, resulting in a larger spray range and relatively higher efficiency. Furthermore, the second fixing pipe 350 is closer to the inner wall of the tank 100, has a smaller diameter, reducing the risk of water spraying onto the inner wall of the tank 100, minimizing flow velocity loss, and reducing energy consumption.
[0050] Optionally, a second sideflow pipe 370 communicating with the first chamber 101 is provided on the side wall of the second fixed pipe 350, and the other end of the second sideflow pipe 370 extends into the first chamber 101. In this way, when the second expansion bag 360 is squeezed, part of the circulating water in the second fixed pipe 350 flows into the first chamber 101 along the second sideflow pipe 370, and the water flow sprayed from the second sideflow pipe 370 is perpendicular to the water flow sprayed from the second fixed pipe 350, which makes the disorder and mixing effect of the water flow better, accelerates the mixing of circulating water in different areas, and thus reduces the temperature difference.
[0051] Specifically, both the first fixing tube 310 and the second fixing tube 350 are fixedly connected to the partition 110. This ensures relatively high stability of the connection.
[0052] Optionally, a plurality of diversion frames 380 are fixedly installed inside the first chamber 101, each diversion frame 380 intersecting the axis of a second fixed pipe 350. In this way, the water jet from the second fixed pipe 350 flows onto the diversion frame 380, and the diversion frame 380 guides the water flow to both sides of the diversion frame 380, increasing the flow angle and range of the water flow, thereby accelerating the mixing of circulating water in different areas and reducing the temperature difference.
[0053] Optionally, each diversion frame 380 is equipped with a diversion plate 381. In this way, the diversion frame 380 and the diversion plate 381 work together to guide the water flow sprayed from the second fixed pipe 350, further increasing the flow angle and range of the water flow, so that the circulating water in different areas mixes more quickly, thereby reducing the temperature difference.
[0054] Specifically, there are two second fixed pipes 350 and two diverter frames 380.
[0055] Optionally, each second sideflow pipe 370 passes through a corresponding diverter 380. This provides support for the second sideflow pipe 370 via the diverter 380, reducing the risk of swaying. The water flow sprayed in the second sideflow pipe 370 will not intersect with the water flow guided by the diverter 380, allowing for a relatively large flow range.
[0056] Combination Figure 4 and Figure 5 As shown, optionally, the extrusion member 330 includes an extrusion plate 331. The extrusion plate 331 is movably disposed within the second chamber 102. Thus, the extrusion plate 331 moves within the second chamber 102, capable of extruding the first expansion bag 320 and causing the first expansion bag 320 to eject water. When the extrusion plate 331 moves away from the first expansion bag 320, the first expansion bag 320 can recover its expansion under water pressure.
[0057] Optionally, the squeeze plate 331 can abut against the second expansion bag 360 to squeeze the second expansion bag 360. Thus, the squeeze plate 331 moves within the second chamber 102, squeezing the second expansion bag 360 to cause it to eject water. When the squeeze plate 331 moves away from the second expansion bag 360, the second expansion bag 360 can recover its expansion under water pressure.
[0058] Optionally, the housing 100 is provided with an electric push rod 332, the output end of which extends through the housing 100 into the second chamber 102 and connects to the side wall of the extrusion plate 331 facing away from the first expansion bag 320. In this way, the electric push rod 332 provides power for the movement of the extrusion plate 331 within the second chamber 102.
[0059] Optionally, the top of the housing 100 is provided with an exhaust pipe 120. In this way, since the heat conduction effect of air is poor, the gas inside the housing 100 can be discharged through the exhaust pipe 120, so that the housing 100 can be filled with circulating water, reducing the loss of heat transfer.
[0060] Specifically, the exhaust pipe 120 is equipped with a first sealing cap.
[0061] Optionally, a drain pipe 130 is provided at the bottom of the tank 100. This facilitates the rapid discharge of circulating water from the tank 100.
[0062] Specifically, a second sealing cap is provided on the drain pipe 130.
[0063] Optionally, the bottom of the housing 100 is provided with a connecting pipe 140 for connecting to the heating pipe, and the connecting pipe 140 passes through the second chamber 102 and connects to the first chamber 101. In this way, the second chamber 102 and the heating pipe are connected by the connecting pipe 140, so that water in the heating pipe can flow into the second chamber 102 for heating, and water in the second chamber 102 can also flow back to the heating pipe through the connecting pipe.
[0064] Optionally, multiple connecting pipes 140 are provided, preferably four. This results in a relatively large number of connecting pipes 140, increasing the speed of circulating water flow between the second chamber 102 and the heating pipe.
[0065] Optionally, the housing 100 is inclined, and a first support frame 150 and a second support frame 160 are fixedly provided at the bottom of the housing 100. In this way, the first support frame 150 and the second support frame 160 provide support for the housing 100.
[0066] Optionally, a heating element is provided in the first chamber 101. In this way, the heating element can heat the circulating water in the second chamber 102 in bad weather.
[0067] Optionally, the heating element is a heating rod. In this way, the circulating water in the second chamber 102 can be heated by the heating rod in bad weather.
