[0023] This application is based on the inventor's discoveries and understanding of the following facts and problems:

[0024] Air conditioning systems account for more than half of a building's total energy consumption. Reducing air conditioning system energy consumption plays a crucial role in energy conservation and emission reduction. The characteristics of the building envelope and energy utilization efficiency are important factors affecting the energy consumption of air conditioning systems, especially in hot and humid regions where the summer is long and hot, and solar radiation entering the building through windows has a significant impact on the building's cooling load.

[0025] Water-flow windows consist of two or more layers of glass and circulation pipes, with water flowing between the glass layers. The water flow absorbs and carries away solar heat from the glass surface, thereby reducing the indoor cooling load.

[0026] In related technologies, water flow window systems absorb heat from the glass within their interlayer and then flow through pipes to a heat exchanger for heat exchange, preheating domestic hot water. However, due to the influence of sunlight duration and solar irradiance levels, the generated hot water temperature is relatively low and cannot be used directly, requiring auxiliary heating with an electric heater, which also consumes energy. Therefore, it does not effectively achieve energy conservation. Furthermore, in tropical and subtropical commercial and office buildings, the demand for hot water is not high in summer. To reduce the temperature of the circulating water within the water flow window system, excess hot water generated must be discharged into the building's drainage system, failing to recover heat energy and wasting water resources.

[0030] The water flow window system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0031] like Figures 1-3 As shown, the water flow window system 1 according to an embodiment of the present utility model includes an air conditioning unit, a sunny water flow window 20, a shady water flow window 30, a condensate tank 40, a first heat exchanger 50, and a second heat exchanger 60.

[0032] The condensate tank 40 is suitable for collecting condensate generated by the air conditioning equipment. The first heat exchanger 50 has a first condensate flow channel 51 and a first circulating water flow channel 52. The first condensate flow channel 51 is connected to the condensate tank 40, and the first circulating water flow channel 52 is connected to the inlet 24 of the sunny-side water flow window 20 and the outlet 25 of the shady-side water flow window 30, respectively. The second heat exchanger 60 has a second condensate flow channel 61 and a second circulating water flow channel 62. The second condensate flow channel 61 is connected to the condensate tank 40, and the second circulating water flow channel 62 is connected to the outlet 25 of the sunny-side water flow window 20 and the inlet 24 of the shady-side water flow window 30, respectively.

[0033] Specifically, the sunny-side water flow window 20 is located on the sunny side of the building, that is, the side that is frequently directly exposed to the sun 2, while the shady-side water flow window 30 is located on the shady side of the building, that is, the side that is not frequently directly exposed to the sun 2.

[0034] The first condensate flow channel 51 and the first circulating water flow channel 52 are adapted to exchange heat in the first heat exchanger 50, and the second condensate flow channel 61 and the second circulating water flow channel 62 are adapted to exchange heat in the second heat exchanger 60.

[0035] The sunny-side water flow window 20 is equipped with an inlet 24 and an outlet 25, while the shady-side water flow window 30 is equipped with an inlet 24 and an outlet 25.

[0036] The low-temperature condensate generated by the air conditioning equipment is collected and stored in the condensate tank 40 and distributed to the first heat exchanger 50 and the second heat exchanger 60, flowing through the first condensate channel 51 of the first heat exchanger 50 and the second condensate channel 61 of the second heat exchanger 60. Water in the sun-facing water flow window 20 and the shaded water flow window 30 circulates between them. Water flowing from the outlet 25 of the shaded water flow window 30 to the inlet 24 of the sun-facing water flow window 20 passes through the first circulating water channel 52 of the first heat exchanger 50, and water flowing from the outlet 25 of the sun-facing water flow window 20 to the inlet 24 of the shaded water flow window 30 passes through the second circulating water channel 62 of the second heat exchanger 60. In the first heat exchanger 50, the low-temperature condensate in the first condensate channel 51 exchanges heat with the circulating water in the first circulating water channel 52, causing the circulating water to cool down and flow towards the sunlit water flow window 20. The circulating water absorbs heat from the surface of the sunlit water flow window 20 after being exposed to sunlight, forming a higher-temperature circulating water before being discharged. In the second heat exchanger 60, the low-temperature condensate in the second condensate channel 61 exchanges heat with the higher-temperature circulating water in the second circulating water channel 62, causing the circulating water temperature to decrease and flow towards the shaded water flow window 30, thus lowering the temperature of the circulating water in the shaded water flow window 30.

[0037] Therefore, the low-temperature condensate generated by the air conditioning system can be used to exchange heat with the circulating water, thereby reducing the temperature of the circulating water. On the one hand, the heat exchange between the condensate and the circulating water in the first heat exchanger 50 can be used to pre-cool the circulating water flowing towards the sunny side water flow window 20, thereby further reducing the heat entering the building interior through the sunny side water flow window 20. On the other hand, the higher-temperature circulating water discharged from the sunny side water flow window 20 can exchange heat with the lower-temperature condensate in the second heat exchanger 60, thereby cooling the circulating water that has absorbed heat from solar radiation. After the circulating water temperature is reduced, it flows towards the shady side water flow window 30, reducing the heat entering the interior from the shady side of the building.

[0038] According to the water flow window system 1 of this utility model embodiment, by setting a condensate tank 40, a first heat exchanger 50 and a second heat exchanger 60, the first condensate flow channel 51 is connected to the condensate tank 40, the first circulating water flow channel 52 is connected to the inlet 24 of the sunny side water flow window 20 and the outlet 25 of the shady side water flow window 30 respectively, the second condensate flow channel 61 is connected to the condensate tank 40, and the second circulating water flow channel 62 is connected to the outlet 25 of the sunny side water flow window 20 and the inlet 24 of the shady side water flow window 30 respectively, the circulating water between the sunny side water flow window 20 and the shady side water flow window 30 can exchange heat with the condensate water discharged from the air conditioning equipment at a lower temperature. The cooling capacity contained in the condensate water is used to cool the circulating water, thereby reducing the temperature of the circulating water entering the sunny side water flow window 20 and the shady side water flow window 30, thus reducing the heat entering the building interior from the sunny side water flow window 20 and the shady side water flow window 30, reducing the indoor air conditioning cooling load, and reducing the energy consumption of the air conditioning equipment.

[0039] Furthermore, by exchanging heat between the condensate produced by the air conditioning equipment and the circulating water in the water flow window, compared to the method of directly discharging the condensate into the drainage system in related technologies, the cooling capacity of the condensate in the air conditioning equipment can be fully utilized, avoiding the waste of the cooling source.

[0040] Furthermore, by exchanging heat between the condensate generated by the air conditioning equipment and the circulating water in the water flow window, compared to the method of using the circulating water for preheating domestic hot water in related technologies, it is possible to avoid directly discharging the excess hot water generated by the water flow window system into the drainage system in order to reduce the temperature of the circulating water when the ambient temperature is high and the demand for domestic hot water is not high, thus avoiding the waste of water resources.

[0041] Therefore, the water flow window system 1 according to the present invention can reduce the indoor air conditioning cooling load and has the advantages of good energy saving effect.

[0042] The following description, with reference to the accompanying drawings, describes a water flow window system 1 according to a specific embodiment of the present invention.

[0043] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the water flow window system 1 according to an embodiment of the present utility model includes an air conditioning unit, a sunny water flow window 20, a shady water flow window 30, a condensate tank 40, a first heat exchanger 50, and a second heat exchanger 60.

[0044] Specifically, such as Figures 1-3 As shown, each of the sunny-side water flow window 20 and the shady-side water flow window 30 includes a window frame 21 and two glass plates 22. The two glass plates 22 are spaced apart and together with the window frame 21 define a water flow cavity 23. A water inlet 24 and a water outlet 25 are located on the window frame 21 and communicate with the water flow cavity 23. This facilitates the formation of a water flow space, using the flow of water within the water flow cavity 23 to remove the temperature from the surface of the glass plates 22.

[0045] Advantageously, such as Figures 1-3 As shown, the inlet 24 and outlet 25 on each window frame 21 are located on two opposite surfaces in the horizontal direction of the window frame 21 (the vertical direction is shown by the arrows in the figure, and the horizontal direction is perpendicular to the vertical direction). The inlet 24 of the sunny-side water flow window 20 is located near the upper end of the sunny-side water flow window 20, and the outlet 25 is located near the lower end of the sunny-side water flow window 20. The inlet 24 of the shady-side water flow window 30 is located near the lower end of the shady-side water flow window 30, and the outlet 25 is located near the upper end of the shady-side water flow window 30. This prolongs the time required for the circulating water to flow in the water flow cavity 23, allowing the circulating water to fully absorb the heat from the surface of the glass plate 22.

[0046] More specifically, such as Figure 1As shown, one end of the first condensate channel 51 is connected to the condensate tank 40 and the other end is connected to the building drainage system. Similarly, one end of the second condensate channel 61 is connected to the condensate tank 40 and the other end is connected to the building drainage system. Specifically, the other end of the first condensate channel 51 is connected to a first drain pipe 53, and the other end of the second condensate channel 61 is connected to a second drain pipe 63. Both the first drain pipe 53 and the second drain pipe 63 are connected to the building drainage system. This facilitates the discharge of condensate after heat exchange.

[0047] Figures 1-3 A water flow window system 1 according to some examples of the present invention is shown. For example... Figures 1-3 As shown, the water flow window system 1 also includes a first circulation pipe 71 and a second circulation pipe 72. The first circulation pipe 71 is connected to the outlet 25 of the negative water flow window 30 and the inlet 24 of the positive water flow window 20, respectively. A first circulation water channel 52 is connected to the first circulation pipe 71. The second circulation pipe 72 is connected to the inlet 24 of the negative water flow window 30 and the outlet 25 of the positive water flow window 20, respectively. A second circulation water channel 62 is connected to the second circulation pipe 72. This facilitates the circulation of water between the water flow window and the heat exchanger.

[0048] Advantageously, such as Figure 1 As shown, the water flow window system 1 also includes a circulating water pump 80, which is connected to at least one of the first circulating pipe 71 and the second circulating pipe 72. This allows the circulating water pump 80 to provide driving force for the flow of circulating water, facilitating smooth flow of circulating water between the water flow window and the heat exchanger.

[0049] Specifically, such as Figure 1 As shown, the water flow window system 1 also includes a condensate collection pipe 90. The air conditioning equipment includes an air handling unit 11 and a fan coil unit 12. The condensate collection pipe 90 is connected to the air handling unit 11, the fan coil unit 12, and the condensate tank 40. Specifically, the air handling unit 11 has a cooling surface section 13. This facilitates the collection of condensate generated by the air conditioning equipment.

[0050] More specifically, such as Figure 1 As shown, the water flow window system 1 also includes a first distribution pipe 101 and a second distribution pipe 102. The first distribution pipe 101 is connected to the condensate tank 40 and the first condensate flow channel 51, respectively, and the second distribution pipe 102 is connected to the condensate tank 40 and the second condensate flow channel 61, respectively. This facilitates the distribution of condensate in the condensate tank 40 to the first heat exchanger 50 and the second heat exchanger 60.

[0051] Furthermore, such as Figure 1As shown, the water flow window system 1 also includes a first on / off valve 111 and a second on / off valve 112. The first on / off valve 111 is connected to the first distribution pipe 101, and the second on / off valve 112 is connected to the second distribution pipe 102. This allows the first on / off valve 111 and the second on / off valve 112 to control the opening and closing of the first distribution pipe 101 and the second distribution pipe 102, thereby controlling the heat exchange process of the first heat exchanger 50 and the second heat exchanger 60. For example, when factors such as changes in the solar canopy angle mean that a reduction in the circulating water temperature is not necessary, the corresponding on / off valve can be closed.

[0052] More advantageously, the water flow window system 1 also includes a first water pump and a second water pump, the first water pump being connected to the first distribution pipe 101 and the second water pump being connected to the second distribution pipe 102. This provides driving force for the condensate to be transported from the condensate tank 40 to the first heat exchanger 50 and the second heat exchanger 60, facilitating the smooth transport of condensate.

[0053] Other configurations and operations of the water flow window system 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
