[0002] As building quality improves, windows, compared to walls, experience greater heat loss due to heat transfer over the same area. According to general statistics, heat loss through glass windows is five to six times greater than that through walls, accounting for over one-third of a building's total heat dissipation. Therefore, optimizing window energy efficiency has become a key breakthrough in improving building energy efficiency.

[0045] The water inlet 313 of the second thermal insulation energy storage tank is connected to the municipal pipe network 401, and the water outlet 314 of the second thermal insulation energy storage tank is connected to the user end 403;

[0046] Wherein, the solar energy component 402 is a solar thermal component, a solar photovoltaic component or a solar photovoltaic thermal component;

[0048] The energy-saving system further includes: a heat exchange unit and a second water pump 503. The controller 501 is connected to the second water pump 503 by signal. The heat exchange unit is used to adjust the water path temperature in the water flow window unit 100 so that the water path temperature in the water flow window unit 100 reaches a preset temperature. The heat exchange unit is connected to the heat pump unit. The first water pump 502 is used to transfer the water in the heat exchange unit to the water flow window unit 100. The second water pump 503 is used to transport the working medium in the heat pump to the heat exchange unit and to The water channel in the water flow window unit 100 exchanges heat. The heat exchange unit is a plate heat exchanger 201. The water inlet 311 of the first thermal insulation energy storage box is connected to the second outlet 205 of the plate heat exchanger.

[0049] The first water pump is disposed on a pipeline connecting the first outlet 203 of the plate heat exchanger and the window inlet 107 of the water flow window unit 100 .

[0050] When the energy-saving system is a closed system and the water window provides cooling:

[0051] When the indoor temperature is higher than the first set temperature range, the first water pump 502 and the second water pump 503 are started, and the four-way reversing valve 308 is adjusted so that the first heat exchanger 303 is an evaporator and the second heat exchanger 304 is a condenser. The refrigerant in the heat pump unit absorbs heat from the first thermal insulation energy storage tank 301 through the first heat exchanger 303 and releases heat to the second thermal insulation energy storage tank 302 in the second heat exchanger 304. The refrigerant in the first thermal insulation energy storage tank 301 that has absorbed heat is transported to the plate heat exchanger 201 via the second water pump 503. The refrigerant in the water flow window unit 100 exchanges heat with the refrigerant that has absorbed heat in the plate heat exchanger 201 and then returns to the water flow window unit 100 for radiant cooling.

[0052] When the indoor temperature is lower than the first set temperature range, if there is a demand for hot water in the building, the second thermal insulation energy storage tank 302 and the solar panel 402 jointly supply hot water to the user end 403, and the municipal pipe network 401 replenishes water to the second thermal insulation energy storage tank 302.

[0053] When the energy-saving system is a closed system and the water flow window is used for heating:

[0054] When the indoor temperature is lower than the second set temperature range, the first water pump 502 and the second water pump 503 are started, and the four-way reversing valve 308 is adjusted so that the second heat exchanger 304 acts as an evaporator and the first heat exchanger 303 acts as a condenser. The refrigerant in the heat pump unit absorbs heat from the second thermal insulation energy storage tank 302 through the second heat exchanger 304 and releases heat to the first thermal insulation energy storage tank 301 when passing through the first heat exchanger 303. After the refrigerant in the first thermal insulation energy storage tank 301 absorbs heat, it is transported by the second water pump 503 to the plate heat exchanger 201 for heat release. The refrigerant in the water flow window unit 100 exchanges heat with the refrigerant in the plate heat exchanger 201 and then returns to the water flow window unit 100 for radiant heating.

[0055] When the indoor temperature is higher than the second set temperature range, and when the temperature of the first thermal insulation energy storage tank 301 is lower than the fourth set temperature range, the auxiliary electric heater 305 in the first thermal insulation energy storage tank 301 is turned on; when the temperature of the first thermal insulation energy storage tank 301 is higher than the fourth set temperature range, the third water pump 504 is turned on to transport the hot working medium in the first thermal insulation energy storage tank 301 to the second thermal insulation energy storage tank 302.

[0056] The specific principles are:

[0057] For a closed-loop system, during the cooling season, when the indoor temperature rises above the first set temperature range, the first water pump 502 and the second water pump 503 are activated. By adjusting the four-way reversing valve 308, the first heat exchanger 303 in the heat pump unit functions as the evaporator, and the second heat exchanger 304 functions as the condenser. The refrigerant evaporates after being decompressed by the throttle valve. It absorbs heat from the first insulated energy storage tank 301 through the first heat exchanger 303. The refrigerant vapor is then compressed by the compressor 306, releasing heat into the second insulated energy storage tank 302 as it passes through the second heat exchanger 304. The low-temperature refrigerant in the first insulated energy storage tank 301 is then transported by the second water pump 503 to the plate heat exchanger 201, where it exchanges heat with the circulating refrigerant in the adaptive radiant window. Finally, the circulating refrigerant is transported by the first water pump 502 to the adaptive radiant window energy-saving system, providing radiant cooling to the room. When the indoor temperature falls below the first set temperature range, the speed of the first and second water pumps 502 and 503 is reduced or stopped to maintain thermal comfort. Furthermore, when there is a demand for hot water within the building, the second thermal storage tank 302 and the solar thermal or photovoltaic modules, or photovoltaic / thermal modules, work together to supply hot water to the user. Simultaneously, the municipal pipe network 401 connects to the second thermal storage tank 302 to replenish water.

[0058] For a closed-loop system, during the heating season, when the indoor temperature falls below the second set temperature range, the first and second water pumps 502 and 503 are activated. By adjusting the four-way reversing valve 308, the second heat exchanger 304 in the heat pump unit functions as an evaporator, and the first heat exchanger 303 functions as a condenser. The refrigerant evaporates after being decompressed by the throttle valve. It absorbs heat from the second insulated energy storage tank 302 through the second heat exchanger 304. The refrigerant vapor is then compressed by the compressor 306, releasing heat into the first heat exchanger 303 as it passes through the first heat exchanger 303. The water in the first insulated energy storage tank 301 gains heat, which is then transported by the second water pump 503 to the plate heat exchanger 201, where it releases heat to the circulating medium in the adaptive radiant window. Finally, the circulating medium is transported by the first water pump 502 to the adaptive radiant window energy-saving system, where it provides radiant heating to the room. When the indoor temperature rises above the second set temperature range, the speeds of the first and second water pumps 502 and 503 are reduced or stopped. When the temperature of the first thermal insulation energy storage tank 301 is lower than the fourth set temperature range, the auxiliary electric heater 305 in the first thermal insulation energy storage tank 301 is turned on; when the temperature of the first thermal insulation energy storage tank 301 is higher than the fourth set temperature range, the valve on the first bypass pipe 309 is opened and adjusted (the first bypass pipe 309 is provided with a third water pump 504, and the second bypass pipe 310 is provided with a fourth water pump 505), and part of the hot water is transported to the second thermal insulation energy storage tank 302 and circulated until the heating demand of the fourth set temperature range is met.

[0059] In a closed system, the working fluid in the water flow window is constantly circulating, and its route is: water flow window-plate heat exchanger 201-water flow window-plate heat exchanger 201; the closed system is more energy-efficient, and the flowing working fluid inside the closed system is a liquid with higher heat transfer efficiency, such as antifreeze or nanofluid, which is suitable for colder areas and seasons, and can transfer heat more efficiently. At the same time, there is no material exchange between the flowing working fluid and the outside world, which reduces maintenance requirements and is suitable for projects with high maintenance costs and difficulty. In addition, the energy-saving window system in the closed system is an independent system, which is more conducive to fault isolation.

[0060] The type of water flow window in this embodiment can be selected arbitrarily: the water flow window can adopt different water flow drive modes (natural buoyancy drive / forced flow driven by water pump), different heat exchangers (immersion heat exchanger, shell and tube heat exchanger), etc.; similarly, the water flowing in the water flow window can also be replaced with antifreeze solution, nanofluid, dye fluid and other liquids according to the use occasion and needs. Figure 1 and Figure 2 It is an optimal water flow window design, which adopts forced flow driven by a water pump and a heat exchanger-free design.

[0061] The water flow window unit 100 provided by the present invention has a simple structure, is made of common materials, and is easy to install. The energy-saving system of the water flow window unit 100 can intelligently adjust its operating status according to the indoor and outdoor environment and the needs of personnel, providing indoor radiation cooling / heating, reducing the amount of indoor cooling and heating loads; at the same time, it reduces unnecessary high-grade energy consumption, achieves coordinated regulation of indoor load quantity and quality, and effectively improves the energy efficiency level of the building; the control method is precise, and can be more effectively controlled and adjusted according to various complex environments, with a wider range of applicable climate zones and application scenarios. The building hot water supply system can continuously provide preheated domestic water at a certain temperature to the indoor space to meet the water needs of indoor personnel, reduce the installation area and power consumption of conventional water heaters, and achieve good energy-saving effects.
