[0024] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.

[0025] Combined with Figure 1 As shown, a technical solution is proposed in the first aspect of the present utility model. A heat recovery system includes a water storage container 10, a water supply system, a two-way pump 30, at least one interlayer window component 40, and a sunshade component 50.

[0026] Among them, the water storage container 10 is used to store hot water. The volume of the water storage container 10 can be selected as 60 - 80L to meet the daily domestic water use. The structural wall is made of heat-insulating material to achieve heat preservation of the hot water.

[0027] The water supply system includes a water supply pipe 21, a first pipe 22, a second pipe 23, and a third pipe 24. Valves are provided on the water supply pipe 21, the first pipe 22, the second pipe 23, and the third pipe 24. The water supply pipe 21 is a municipal water supply pipe, and the first pipe 22, the second pipe 23, and the third pipe 24 are all water supply or return pipes for supplying water to the water storage container 10 or the interlayer window component 40.

[0028] The two-way pump 30 is connected to the water supply system. Through the pumping action of the two-way pump 30, the water in the water supply pipe 21 can be injected towards the interlayer window component 40, the water in the interlayer window component 40 can be injected into the water storage container 10, and the water in the interlayer window component 40 can also be pumped back to form a vacuum interlayer in the interlayer window component 40.

[0029] In this way, it not only meets the flexible use of water but also improves the heat preservation and heat recovery performance of the interlayer window component 40.

[0030] Among them, at least one interlayer window component 40 is provided on the top of the passive house. The interlayer window component 40 includes an interlayer 411. Water can be stored or the interlayer 411 can be evacuated in the interlayer 411. Heat can be recovered through the water medium, and evacuating the air can improve the heat preservation performance of the interlayer window component 40.

[0031] Furthermore, the sunshade component 50 is arranged below the interlayer window component 40. Through the sunshade component 50, the light and heat entering the room through the interlayer window component 40 can be controlled, which is beneficial for users to adjust according to their needs.

[0032] Combined Figure 1 As shown, both ends of the two-way pump 30 are respectively connected to the water supply pipe 21 and the first pipe 22. The other end of the first pipe 22 is connected to the interlayer 411 of the interlayer window component 40. Both ends of the second pipe 23 are respectively connected to the interlayer 411 of the interlayer window component 40 and the water storage container 10. Both ends of the third pipe 24 are respectively connected to the two-way pump 30 and the water storage container 10.

[0033] Preferably, the two-way pump 30 includes a gear pump. A first valve 211 is connected to the water supply pipe 21. The first valve is a manual valve. A second valve 221 is connected to the first pipe 22. The second valve 221 is an automatic valve. A third valve 231 is connected to the second pipe 23. The third valve 231 is an automatic valve. A fourth valve 241 is connected to the third pipe 24. The fourth valve 241 is a manual valve.

[0034] Furthermore, a temperature sensor is provided in the interlayer 411 for detecting the water temperature in the interlayer 411.

[0035] In an alternative embodiment, when injecting water into the interlayer 411, the first valve 211 is opened. Defining injecting water into the interlayer 411 as the first direction, when the two-way pump 30 operates in the first direction, the second valve 221 and the third valve 231 are set to be linked with the two-way pump 30. When the two-way pump 30 is opened, the second valve 221 and the third valve 231 are opened. The two-way pump 30 pumps water upward to inject water into the interlayer 411. When the interlayer 411 is full, stop injecting water. When the water temperature in the interlayer 411 reaches between 55 and 65 degrees Celsius, continue injecting water. When the water temperature in the interlayer 411 drops below 55 degrees Celsius, stop injecting water. In this way, hot water is continuously collected in the water storage container 10. Until after the solar irradiance intensity drops, the two-way pump 30 pumps water in the reverse direction. At this time, keep the third valve 231 closed, open the second valve 221 and the fourth valve 241, and pump out the water in the interlayer 411 to form a certain degree of vacuum in the interlayer 411, which is beneficial to improving the heat preservation effect of the interlayer window component 40.

[0036] Combined Figure 2 As shown, the interlayer window component 40 includes a glass plate 41 and a sealing structure 42 wrapped around the glass plate. An interlayer 411 is formed between the glass plate 41 and the sealing structure 42. The glass plate 41 is arranged obliquely so that the interlayer 411 has a low end and a high end.

[0037] Preferably, at least two connecting pipes 43 are provided on the sealing structure 43. The connecting pipes 43 communicate with the interlayer 411. One of the connecting pipes 43 is located at the high end of the interlayer 411, and the other connecting pipe 43 is located at the low end of the interlayer 411.

[0038] In this way, supplying water from the low end of the interlayer 411 can ensure that the injected water completely fills the entire interlayer 411. After being heated by absorbing solar radiation, water can continue to be injected into the interlayer 411 from the bottom, and the hot water overflows from the upper part and enters the water storage container 10 through the second pipe 23. When the solar irradiation heat drops, in order to prevent the indoor heat from spilling out, as Figure 3 shown, pumping water from the low end of the interlayer 411 to make the water flow out of the interlayer 411, so as to form a certain degree of vacuum in the interlayer 411 and improve the heat insulation effect of the interlayer window component 40.

[0039] Furthermore, in combination with Figure 2-3 shown, the sunshade component 50 includes a first sunshade film 51 and a second sunshade film 52. The first sunshade film 51 and the second sunshade film 52 are parallel. Both the first sunshade film 51 and the second sunshade film 52 include a reflection area 511 and a transmission area 512. By controlling the relative positions of the first sunshade film 51 and the second sunshade film 52, the reflection areas 511 and the transmission areas 512 of the first sunshade film 51 and the second sunshade film 52 overlap or stagger each other.

[0040] In an alternative embodiment, the first sunshade film 51 and the second sunshade film 52 are connected end to end and supported by two rotatable rollers. When the rollers rotate, the reflection areas 511 and the transmission areas 512 on the first sunshade film 51 and the second sunshade film 52 can be controlled to overlap or stagger each other.

[0041] Optionally, the first sunshade film 51 and the second sunshade film 52 are PVC films, and the reflection area 511 of the PVC film is coated with a silver reflective layer.

[0042] In this way, when the external light intensity is high, the reflection areas 511 on the first sunshade film 51 and the second sunshade film 52 are staggered from each other to achieve the maximum reflection effect and sunshade effect. The radiation heat indoors is low, and the radiation heat in the interlayer 411 is high. When the external light intensity is low, the reflection areas 511 on the first sunshade film 51 and the second sunshade film 52 overlap each other to achieve the minimum reflection effect and sunshade effect. The radiation heat indoors is high, and the interlayer 411 also has a considerable amount of radiation heat to provide energy for heating water.

[0043] A technical solution is proposed in the second aspect of the present utility model. A passive house includes the above-mentioned heat recovery system, wherein the interlayer window component 40 is arranged on the roof on the sunny side.

[0044] Combined with the above embodiments, the utility model connects a water supply system in the interlayer of the interlayer window component, and can recover the irradiated heat of the sun through the water medium flowing in the interlayer. It can not only reduce the irradiated heat of the sun on the indoor, but also store the excess heat in the form of hot water. In addition, when the irradiation intensity of the sun drops, by pumping out the water in the interlayer and cooperating with the action of water pressure, a certain degree of vacuum can be formed in the interlayer to improve the heat preservation effect of the interlayer window component.

[0045] Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
