Description

Technical Field

[0001] The present invention belongs to the technical field of construction, and particularly relates to a solar water heating and sunshading integrated window and a solar water heating and sunshading system. Background Art

[0002] The information disclosed in this background art section is only intended to enhance the understanding of the overall background art of the present invention, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those skilled in the art.

[0003] In most parts of southern China, it is hot in summer with strong heat radiation. Using sunshading can greatly reduce external heat gain. Sunshading can be achieved through building structure sunshading, sunshading integrated windows, and installing additional curtain blinds. Experimental studies have shown that external sunshading is superior to internal sunshading and can effectively block outdoor heat gain. However, considering that installing external blinds on many high-rise buildings has potential safety hazards of being easily damaged due to wind and rain, and there are also problems such as inconvenient maintenance, sunshading integrated windows, that is, middle-mounted blind integrated windows, have emerged as the times require. Although the heat insulation effect of middle-mounted blinds is better than that of internally installed blinds, it is lower than that of external sunshading. At the same time, there is a problem that the air interlayer where the blinds are located is heated by the heat reflected by sunlight and the heat in the cavity is not easily dissipated, which affects the indoor temperature. At the same time, it also poses higher requirements for the built-in blinds to work in high-temperature and high-humidity environments, resulting in problems such as mechanical vulnerability or a significant increase in cost. Therefore, how to achieve a window that provides sunshading in summer and thermal insulation in winter is the direction we are thinking about. Summary of the Invention

[0027] Embodiment 1

[0028] See Figures 1 to 4 , as shown in the legend therein, a solar water heating and sunshade integrated window includes a window frame 1. The window frame 1 is provided with a window frame opening for installing a window glass 2. The window frame 1 has a hollow inner cavity 11. The window glass 2 has an air interlayer 21. The hollow inner cavity 11 is connected to the air interlayer 21 for ventilation. A water storage water pipe 31, a heat exchange component 32, and a built-in water pump 33 are provided in the hollow inner cavity 11. The water storage water pipe 31 can contract and expand. Part of the heat exchange component 32 is located inside the water storage water pipe 31, and part of the heat exchange component 32 extends outside the window frame 1. A water storage sunshade curtain 41 and a driving assembly are provided in the air interlayer 21. The water storage sunshade curtain 41 can be retracted and unfolded. The built-in water pump 33 is connected to the water storage water pipe 31 and the water storage sunshade curtain 41 to convey water between the water storage water pipe 31 and the water storage sunshade curtain 41. The driving assembly is connected to the water storage sunshade curtain 41 and drives the water storage sunshade curtain 41 to expand and contract.

[0029] The above window frame is a heat-insulating bridge-breaking window frame. The above window glass includes ordinary glass 22 and two layers of heat-insulating glass 23. An inert gas interlayer 24 is provided between the two layers of heat-insulating glass, and the above air interlayer 21 is provided between the ordinary glass and the heat-insulating glass. Air 100 is in the air interlayer. Both the above water storage water pipe and the water storage sunshade can be telescopic. The above water storage water pipe is distributed in a concave shape at three sides of the window frame, or the above water storage water pipe is distributed in a square shape at four sides of the window frame. The above driving assembly drives the water storage sunshade to expand and contract. When the water storage sunshade shortens, the water in the water storage sunshade is squeezed into the water storage water pipe. When the water storage sunshade elongates, the above built-in water pump conveys water between the water storage water pipe and the water storage sunshade through the water conveyance pipe 34, so that the water temperatures in the water storage water pipe and the water storage sunshade are the same. The air interlayer of the window glass is connected to the hollow inner cavity of the window frame through the ventilation pipe 35, and air can pass between the air interlayer and the hollow inner cavity, ensuring internal air pressure balance when the volume of the water storage sunshade and the water storage water pipe changes synchronously (one contracts and the other expands). When the water storage sunshade gets heated and its temperature rises, it can ensure that there is an elastic space inside to accommodate the water vapor and the slight expansion of the water volume. This solution is a reform based on the existing built-in louver sunshade and heat insulation integrated window. The original louvers are replaced with a water storage sunshade. The water storage sunshade absorbs solar radiation, provides heat insulation and sunshade, and at the same time, the absorbed solar energy is converted into hot water for storage, which can be used for bathroom use or as a supplementary heat insulation function in winter when the solar radiation intensity is low or at night. This window is applicable to hot areas that require sunshade facilities, can reduce external sunshade facilities, and is applicable to energy-saving renovation of window sashes in existing buildings, especially residential buildings or high-rise buildings.

[0030] In the preferred implementation mode of this embodiment, two of the above built-in water pumps 33 are provided in the above hollow inner cavity 11. The inlet of one of the above built-in water pumps 33 is connected to the above water storage water pipe 31, and the outlet is connected to the above water storage sunshade 41. The inlet of the other above built-in water pump 33 is connected to the above water storage sunshade 41, and the outlet is connected to the above water storage water pipe 31. The above hollow inner cavity is in a square shape, and the two built-in water pumps are arranged in the upper side channel of the square shape. The water storage water pipe in the window frame is connected to the water storage sunshade in a double-pump mode, and a one-in-one-out water circulation is realized when the water storage sunshade is unfolded (the water storage sunshade elongates), ensuring that the water temperature in the water storage sunshade is the same as the water temperature in the water storage water pipe in the window frame. In other embodiments, it may also be: one water pump is provided, and this one water pump is used to send the water in the above water storage water pipe into the above water storage sunshade, and the water in the above water storage sunshade is input into the above water storage water pipe under the action of its own weight.

[0032] In the preferred embodiment of this example, the driving assembly includes a horizontal pressing strip 42, two vertical guide rails 43, and a lifting driving device (not shown in the figure). The horizontal pressing strip 42 extends in the horizontal direction and is connected to the lower end of the water storage sunshade curtain 41. The two vertical guide rails 43 extend in the vertical direction and are fixed in the air interlayer 21. The two ends of the horizontal pressing strip 42 are respectively slidably connected to the two vertical guide rails 43. The lifting driving device is connected to the horizontal pressing strip 42 and drives the horizontal pressing strip 42 to lift and lower. Specifically, the above-mentioned horizontal pressing strip is a metal pressing strip, and the above-mentioned lifting driving device is a linear motor. By setting the vertical guide rails and the lifting driving device, it is ensured that the water storage sunshade curtain is smoothly retracted and deployed. In other embodiments, it can also be: the above-mentioned driving assembly includes a spring and a pull rope. The water storage sunshade curtain is deployed by manually pulling the pull rope, and the water storage sunshade curtain is reset and retracted by the spring.

[0033] In the preferred embodiment of this example, the water storage water pipe 31 is a latex flexible low-pressure telescopic water pipe. The above-mentioned water storage water pipe can be telescoped along its length direction. In other embodiments, it can also be: the above-mentioned water storage water pipe can be telescoped along its radial direction.

[0034] In the preferred embodiment of this example, the heat exchange component 32 is a metal water pipe, and both ends of the metal water pipe extend out of the outer side of the window frame 1. The above-mentioned metal water pipe can allow fluid to flow, and the water flowing into the metal water pipe exchanges heat with the water in the water storage water pipe to achieve heat recovery. In other embodiments, it can also be: the above-mentioned heat exchange metal component is a heat conducting wire, and the heat conducting wire is heated by the water in the water storage water pipe, and then the heat conducting wire heats the water in the water storage water tank.

[0035] In the preferred embodiment of this example, the water in the water storage water pipe 31 and the water storage sunshade curtain 41 is high-purity clean water 200 with the same water level and forms a closed water system. To avoid scaling and pollution in the water storage sunshade curtain and the water storage water pipe in the window frame, which reduces the heat conduction efficiency, the water in the water storage sunshade curtain and the water storage water pipe is high-purity clean water, a closed water system. In other embodiments, it can also be: the water in the above-mentioned water storage water pipe and the water storage sunshade curtain can be replaced at any time.

[0036] In a preferred embodiment of this example, the width of a single above-mentioned window frame 1 is not greater than 1.8 m, the thickness of the above-mentioned water storage sunshade curtain 41 is 5-10 mm, and the cross-sectional area of the inner cavity of the above-mentioned window frame 1 is not less than 0.006 ㎡. The thickness of the sunshade interlayer and the size and thickness of the corresponding water storage sunshade curtain bag can be adjusted according to the window area and the local daily radiation intensity.

[0037] The following introduces a solar water heating and sunshade system, which includes a water storage tank 51, an external water pump 52, and the above-mentioned solar water heating and sunshade integrated window. The above-mentioned heat exchange component 32 is a metal water pipe. Both ends of the metal water pipe extend outside the above-mentioned window frame 1 and both extend into the above-mentioned water storage tank 51. The above-mentioned external water pump 52 is connected to the metal water pipe. Ordinary tap water 300 can be in the water storage tank, which can be freely injected and discharged. The two systems are connected for heat exchange through the metal water pipe. The water storage water pipe is connected to an external water heater / water storage tank through a metal water pipe and a double pump, and the water in the water storage water pipe inside the window frame is recycled for heat recovery regularly to ensure that the temperature of the water storage sunshade curtain inside the window is not too high, and at the same time, the bathroom function is realized by using hot water storage.

[0038] In a preferred embodiment of this example, the above-mentioned water storage tank 51 is arranged on the lower side of the above-mentioned window frame 1. The water storage tank is also provided with an external tap water inlet (cold water) 53, an external bathroom outlet (hot water) 54, a bottom drain valve 55, and a vent valve 56 for adjusting air pressure balance at the top.

[0039] To ensure that the temperature of the solar hot water in the water storage sunshade curtain is not too high (such as above 40 °C), and at the same time slow down the material aging speed, this solution recommends that the water storage tank connected to the water storage water pipe inside the window frame has sufficient water capacity. For example, a water storage sunshade curtain with an area of 1 ㎡ and a thickness of 10 mm is matched with a normal temperature water tank with a capacity of 0.03 cubic meters (an external water heater is used to provide basic hot water and a tap water inlet pipe). An inspection opening can be set at the upper part of the sunshade interlayer window frame for convenient maintenance, cleaning, and replacement. Considering the conditions of the closed system inside the window and the material characteristics of the water storage sunshade curtain bag and the embedded elastic water pipe, the general replacement cycle can reach more than 5-10 years.
