DETAILED DESCRIPTION

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

[0024] The energy consumption of air conditioning systems in buildings accounts for more than half of the total energy consumption of buildings. Reducing the energy consumption of air conditioning systems plays a vital role in energy conservation and consumption reduction. The characteristics of building envelopes and energy utilization efficiency are important factors affecting the energy consumption of air conditioning systems, especially in humid and hot areas. The summer is hot and long in a year, and the solar radiation entering the room through the windows has a greater impact on the building's cooling load.

[0025] Water flow windows are composed of two or more layers of glass and circulation pipes, with water flowing between the glass layers. The flow of water absorbs and removes the solar heat on the glass surface, thereby reducing the indoor cooling load.

[0026] In the water flow window system in the related art, the water in the interlayer absorbs the heat from the glass, and then flows through the heat exchanger through the pipe to exchange heat, which is used for preheating domestic hot water. However, on the one hand, due to the influence of the duration of sunlight and the level of solar radiation, the temperature of the hot water generated is relatively low and cannot be used directly. It needs to be auxiliary heated by an electric heater, which also consumes energy and does not actually play a good role in energy saving. On the other hand, in commercial buildings and office buildings in tropical and subtropical areas, the demand for hot water in summer is not high. In order to reduce the temperature of the circulating water in the water flow window system, the excess hot water generated by the water flow window system needs to be discharged to the drainage system in the building, which does not play a role in recovering heat energy and is also a waste of water resources.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

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

[0031] like Figure 1-Figure 3As shown, the water flow window system 1 according to an embodiment of the present invention includes an air conditioning device, a sun-side water flow window 20 , a sun-side water flow window 30 , a condensation water 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 respectively connected to the water inlet 24 of the sunny water flow window 20 and the water outlet 25 of the shady water flow window 30. 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 respectively connected to the water outlet 25 of the sunny water flow window 20 and the water inlet 24 of the shady water flow window 30.

[0033] Specifically, the sunny side water flow window 20 is arranged on the sunny side of the building, that is, the side that is relatively often directly exposed to the sun 2, and the shady side water flow window 30 is arranged on the shady side of the building, that is, the side that is not often directly exposed to the sun 2.

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

[0035] A water inlet 24 and a water outlet 25 are provided on the positive side water flow window 20 , and a water inlet 24 and a water outlet 25 are provided on the negative side water flow window 30 .

[0036] The condensed water with a lower temperature generated by the air-conditioning equipment is collected and stored by the condensed water tank 40, and is distributed to the first heat exchanger 50 and the second heat exchanger 60, and flows through the first condensed water flow channel 51 of the first heat exchanger 50 and the second condensed water flow channel 61 of the second heat exchanger 60. The water in the sunny water flow window 20 and the shady water flow window 30 circulates between the sunny water flow window 20 and the shady water flow window 30, and the water flowing from the water outlet 25 of the shady water flow window 30 to the water inlet 24 of the sunny water flow window 20 passes through the first circulating water flow channel 52 of the first heat exchanger 50, and the water flowing from the water outlet 25 of the sunny water flow window 20 to the water inlet 24 of the shady water flow window 30 passes through the second circulating water flow channel 62 of the second heat exchanger 60. The low-temperature condensed water in the first condensed water flow channel 51 in the first heat exchanger 50 exchanges heat with the circulating water in the first circulating water flow channel 52, so that the circulating water is cooled and then flows to the sunny water flow window 20. The circulating water in the sunny water flow window 20 is exposed to the sun and absorbs the heat from the surface of the sunny water flow window 20 to form circulating water with a higher temperature and is then discharged. The low-temperature condensed water in the second condensed water flow channel 61 in the second heat exchanger 60 exchanges heat with the circulating water with a higher temperature in the second circulating water flow channel 62, so that the circulating water temperature is reduced and then flows to the shady water flow window 30, so that the circulating water temperature in the shady water flow window 30 is reduced.

[0037] Thus, the low-temperature condensed water generated by the air conditioning system can be used to exchange heat with the circulating water to reduce the temperature of the circulating water. On the one hand, the heat exchange between the condensed water and the circulating water in the first heat exchanger 50 can be used to pre-cool the circulating water flowing to the sunny water flow window 20, thereby further reducing the heat entering the building from the sunny water flow window 20. On the other hand, the high-temperature circulating water discharged from the sunny water flow window 20 can be heat-exchanged with the low-temperature condensed water in the second heat exchanger 60, thereby cooling the circulating water that has absorbed the heat from the sun, so that the circulating water temperature is reduced before flowing to the shady water flow window 30, thereby reducing the heat entering the building from the shady side.

[0038] According to the water flow window system 1 of the embodiment of the present invention, by setting a condensation water tank 40, a first heat exchanger 50 and a second heat exchanger 60, the first condensation water flow channel 51 is connected to the condensation water tank 40, the first circulating water flow channel 52 is respectively connected to the water inlet 24 of the sunny water flow window 20 and the water outlet 25 of the shady water flow window 30, the second condensation water flow channel 61 is connected to the condensation water tank 40, and the second circulating water flow channel 62 is respectively connected to the water outlet 25 of the sunny water flow window 20 and the water inlet 24 of the shady water flow window 30, so that the circulating water between the sunny water flow window 20 and the shady water flow window 30 can be heat exchanged with the condensation water with lower temperature discharged by the air-conditioning equipment, and the cold energy contained in the condensation water is used to cool the circulating water, thereby reducing the temperature of the circulating water entering the sunny water flow window 20 and the shady water flow window 30, thereby reducing the heat entering the building room from the sunny water flow window 20 and the shady 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 condensed water produced by the air-conditioning equipment and the circulating water of the water flow window, compared with the method of directly discharging the condensed water into the drainage system in the related art, the cold capacity of the condensed water of the air-conditioning equipment can be fully utilized to avoid wasting the cold source.

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

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

[0042] The water flow window system 1 according to a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the water flow window system 1 according to an embodiment of the present invention includes an air conditioning device, a sun-side water flow window 20 , a sun-side water flow window 30 , a condensation water tank 40 , a first heat exchanger 50 and a second heat exchanger 60 .

[0044] Specifically, Figure 1-Figure 3 As shown, each of the positive water flow window 20 and the negative water flow window 30 includes a window frame 21 and two glass plates 22, the two glass plates 22 are arranged at intervals and define a water flow cavity 23 together with the window frame 21, and a water inlet 24 and a water outlet 25 are arranged on the window frame 21 and communicate with the water flow cavity 23. In this way, it is convenient to form a water flow space, and the temperature of the surface of the glass plate 22 is taken away by the flow of water in the water flow cavity 23.

[0045] Advantageously, if Figure 1-Figure 3 As shown, the water inlet 24 and the water outlet 25 on each window frame 21 are respectively located on two opposite surfaces of the window frame 21 in the horizontal direction (the up and down directions are shown by arrows in the figure, and the horizontal direction is perpendicular to the up and down directions), the water inlet 24 of the sunny water flow window 20 is arranged adjacent to the upper end of the sunny water flow window 20 and the water outlet 25 is arranged adjacent to the lower end of the sunny water flow window 20, and the water inlet 24 of the shady water flow window 30 is arranged adjacent to the lower end of the shady water flow window 30 and the water outlet 25 is arranged adjacent to the upper end of the shady water flow window 30. In this way, the time required for the circulating water to flow in the water flow cavity 23 can be extended, so that the circulating water can fully absorb the heat on the surface of the glass plate 22.

[0046] More specifically, Figure 1As shown, one end of the first condensate flow channel 51 is connected to the condensate tank 40 and the other end is connected to the building drainage system, and one end of the second condensate flow 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 flow channel 51 is connected to the first drain pipe 53, and the other end of the second condensate flow channel 61 is connected to the second drain pipe 63, and the first drain pipe 53 and the second drain pipe 63 are both connected to the building drainage system. In this way, the condensate after heat exchange can be easily discharged.

[0047] Figure 1-Figure 3 The water flow window system 1 according to some examples of the present invention is shown. Figure 1-Figure 3 As shown, the water flow window system 1 further includes a first circulation pipe 71 and a second circulation pipe 72, the first circulation pipe 71 is respectively connected to the water outlet 25 of the shady water flow window 30 and the water inlet 24 of the sunny water flow window 20, the first circulation water flow channel 52 is connected to the first circulation pipe 71, the second circulation pipe 72 is respectively connected to the water inlet 24 of the shady water flow window 30 and the water outlet 25 of the sunny water flow window 20, and the second circulation water flow channel 62 is connected to the second circulation pipe 72. In this way, the circulating water can circulate between the water flow window and the heat exchanger.

[0048] Advantageously, if Figure 1 As shown, the water flow window system 1 further 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. In this way, the circulating water pump 80 can be used to provide a driving force for the flow of circulating water, so as to facilitate the smooth flow of circulating water between the water flow window and the heat exchanger.

[0049] Specifically, Figure 1 As shown, the water window system 1 further includes a condensed water collection pipe 90, the air conditioning equipment includes an air handling unit 11 and a fan coil 12, and the condensed water collection pipe 90 is respectively connected to the air handling unit 11, the fan coil 12 and the condensed water tank 40. Specifically, the air handling unit 11 has a surface cooling section 13. This makes it easy to collect the condensed water generated by the air conditioning equipment.

[0050] More specifically, Figure 1 As shown, the water flow window system 1 further includes a first distribution pipe 101 and a second distribution pipe 102. The first distribution pipe 101 is respectively connected to the condensation water tank 40 and the first condensation water flow channel 51, and the second distribution pipe 102 is respectively connected to the condensation water tank 40 and the second condensation water flow channel 61. In this way, the condensation water in the condensation water tank 40 can be easily distributed to the first heat exchanger 50 and the second heat exchanger 60.

[0051] Furthermore, if Figure 1As shown, the water flow window system 1 further includes a first on-off valve 111 and a second on-off valve 112, wherein 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. In this way, the first on-off valve 111 and the second on-off valve 112 can be used to control the on-off 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 the temperature of the circulating water does not need to be lowered due to factors such as the change in the angle of the sunshade, the corresponding on-off valve can be closed.

[0052] More advantageously, the water flow window system 1 further comprises a first water pump and a second water pump, wherein the first water pump is connected to the first distribution pipe 101, and the second water pump is connected to the second distribution pipe 102. This can provide driving force for the condensed water to be transported from the condensed water tank 40 to the first heat exchanger 50 and the second heat exchanger 60, thereby facilitating the smooth transportation of the condensed water.
