Description

[0001] This application is a divisional application of the patent "An Indoor Dehumidification Method Realized through Windows" with the application number 202110387304.8 and the application date April 12, 2021. Technical Field

[0002] The present invention relates to the technical field of indoor environment control, and specifically to a stepped dehumidifying window installed on the wall of a room. Background Art

[0003] In the southern regions of China, in order to meet the comfort requirements of people in hot and humid weather, it is necessary to use air conditioners for a long time or even all day to cool down and dehumidify the indoor air at the same time. The energy consumption for dehumidification accounts for 1 / 3 to 1 / 2 of the total energy consumption of the air conditioner, which greatly increases the building energy consumption. In winter, for office workers, although not turning on the air conditioner already meets the temperature comfort requirements of people, due to the high air humidity, people have to turn on the air conditioner for dehumidification, which will cause waste of energy. For families, people tend to close the windows tightly to avoid the impact of outdoor humid weather on the indoor environment, but this behavior greatly affects people's health and comfort.

[0004] Chinese Patent No. CN202010536021.0 discloses a dehumidifying window, which includes a window body, a precooler, a solid adsorption dehumidification layer, and an exhaust chamber. Fresh air enters the window body from the precooler through a fan, and the solid adsorption dehumidification layer adsorbs and dehumidifies the air. The dehumidified air enters the room through the first air outlet surface. The problems of this window are that this dehumidification work is a one-way operation and cannot be adjusted. When the air humidity is high, the dehumidification is insufficient, and when the air humidity is low, there is over-dehumidification, which affects human comfort. At the same time, the dehumidification system of this window depends on external power and needs to be externally connected to a power source and cannot work independently. Summary of the Invention

[0005] Aiming at the deficiencies of the above-mentioned prior art, the technical problems to be solved by the present invention are: how to provide an indoor dehumidification method realized through a window and a stepped dehumidifying window installed on the wall of a room that can better adjust the dehumidification effect according to needs and improve the comfort of the outlet air, and further make it independent of external power and work independently to improve applicability.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An indoor dehumidification method implemented through a window, which first cools the fresh air entering the window to condense the water vapor in the fresh air, and then controls the air flow to pass through a dehumidification module to remove the condensed moisture and then send it into the room. It is characterized in that at least two dehumidification modules are arranged in the window. After the fresh air enters, its humidity value is detected, and according to the humidity condition of the fresh air, the fresh air is controlled to pass through only one dehumidification module or more than one dehumidification module for dehumidification.

[0008] In this way, the dehumidification degree can be controlled according to the humidity condition of the fresh air, which can better avoid the situation of insufficient dehumidification or excessive dehumidification, and ensure better comfort of the outlet air. The dehumidification module can be a container filled with a dehumidification solution (the dehumidification solution can be one solution or a mixture of multiple solutions among lithium bromide solution, calcium chloride solution, and lithium chloride solution), or a module with a ventilation effect made of a solid water-absorbing material. The specific implementation method is the prior art and will not be elaborated here.

[0009] Furthermore, at least one low-power dehumidification module and one high-power dehumidification module are arranged in the window. During dehumidification, after detecting the humidity of the fresh air, it is compared with a preset threshold range. When the humidity of the fresh air is less than the preset threshold range, the air flow is controlled to pass through only the low-power dehumidification module. When the humidity of the fresh air falls within the preset threshold range, the air flow is controlled to pass through only the high-power dehumidification module. When the humidity of the fresh air is greater than the preset threshold range, the air flow is controlled to pass through the low-power dehumidification module and the high-power dehumidification module in sequence.

[0010] In this way, three different levels of dehumidification effects can be achieved by relying on two dehumidification modules, and it can be better selected according to needs. The low-power dehumidification module refers to a dehumidification module with relatively lower dehumidification effect, and the high-power dehumidification module refers to a dehumidification module with relatively higher dehumidification effect. Specifically, it can be achieved by increasing or decreasing the volume of the dehumidification module, as long as one is larger than the other. The specific size of the preset threshold range can also be set according to needs and will not be elaborated here.

[0011] Further, this method is realized by installing stepped dehumidification windows on the room walls. The stepped dehumidification windows include a window body. A wind flow channel connecting the outside and the inside of the window is provided on the window body. A fan is installed in the wind flow channel (the fan is preferably installed at the inlet position). A surface cooler and an inlet air humidity sensor are provided at a position near the inlet end of the wind flow channel. A stepped dehumidification pipe network system is formed in the wind flow channel. The stepped dehumidification pipe network system includes a first dehumidification module and a second dehumidification module arranged in series. The dehumidification effect of the first dehumidification module is less than that of the second dehumidification module. A first bypass pipe is arranged in parallel beside the first dehumidification module. A second bypass pipe is arranged in parallel beside the second dehumidification module. A first three-way solenoid valve is further provided at the inlet end of the first dehumidification module. The three interfaces of the first three-way solenoid valve are respectively connected to the pipe at the inlet end of the stepped dehumidification pipe network system, the inlet end of the first bypass pipe, and the first inlet of the first dehumidification module. A second three-way solenoid valve is further provided at the outlet end of the first dehumidification module. The three interfaces of the second three-way solenoid valve are respectively connected to the first outlet of the first dehumidification module, the first inlet of the second dehumidification module, and the inlet of the second bypass pipe. It further includes a controller, and the controller is respectively connected to the inlet air humidity sensor, the first three-way solenoid valve, and the second three-way solenoid valve.

[0012] In this way, this method can be realized by relying on the stepped dehumidification windows. When the windows are in use, the wind flow is cooled and condensed by the surface cooler, and then the humidity situation is detected by the humidity sensor. According to the humidity situation, the wind flow can be specifically controlled to only pass through the first dehumidification module or the second dehumidification module or pass through both dehumidification modules at the same time, achieving three gradients of dehumidification effects. The dehumidification module can be a container filled with a dehumidification solution (the dehumidification solution can be one solution or a mixture of multiple solutions among lithium bromide solution, calcium chloride solution, and lithium chloride solution), or a module made of a solid water-absorbing material with a ventilation effect.

[0013] As an optimization, the outlet end of the first bypass pipe is connected to the inlet end of the second dehumidification module, and a short-circuit pipe with a switch valve is further provided on the first bypass pipe and connected between the first dehumidification module and the second three-way solenoid valve.

[0014] In this way, when dehumidification is not required, the wind flow can bypass the two dehumidification modules to achieve direct air intake for ventilation and air change in the room.

[0015] As an optimization, an indoor humidity sensor is further provided inside the window body.

[0016] In this way, the indoor humidity situation can be detected. When the indoor humidity is too high, the dry wind flow after deep dehumidification can be controlled to be introduced. When the indoor humidity is moderate, the dehumidification effect can be controlled and adjusted to be moderate.

[0017] Further, the indoor humidity sensor is arranged at the lower position on the inner side of the window body. This is because the activities of indoor people are mainly in the lower part of the room, and at the same time, moist air will sink. Therefore, setting the sensor at the lower position can better achieve detection.

[0018] Further, a solar panel is also arranged on the outer surface of the window body. The solar panel is connected to a storage battery through a charge-discharge controller, and the storage battery is connected to the controller.

[0019] In this way, the solar panel can absorb solar energy to charge the storage battery, and then supply power to the controller and other electrical components. This enables the dehumidification work to be independent of external power and improves applicability.

[0020] Further, the upper end of the solar panel is rotatably connected to the upper end of the outer side of the window body. The window body is also provided with a rotatable support rod for pushing the solar panel outwards.

[0021] In this way, the solar panel can better receive sunlight, absorb solar energy, and shade the interior of the room.

[0022] Further, the outlet of the air flow channel is horizontally arranged in the middle of the window, and louvers are arranged at the outlet.

[0023] In this way, the air outlet direction can be adjusted through the louvers.

[0024] Further, a regeneration system is also arranged on the window body. The regeneration system includes a regeneration pipeline. The main pipeline at the inlet end of the regeneration pipeline is connected to the air flow channel before entering the surface cooler. A collector is arranged in the main pipeline at the inlet end of the regeneration pipeline. The regeneration system also includes a first regeneration branch pipe and a second regeneration branch pipe arranged in parallel. The inlet ends of the first regeneration branch pipe and the second regeneration branch pipe are connected to the main pipeline at the inlet end of the regeneration pipeline through a third three-way valve. The outlet ends of the first regeneration branch pipe and the second regeneration branch pipe are connected to the main pipeline at the outlet end of the regeneration pipeline through a fourth three-way valve. The main pipeline at the outlet end of the regeneration pipeline is communicated with the outside of the window. The first dehumidification module is connected to the first regeneration branch pipe through its second inlet and second outlet. The second dehumidification module is connected to the second regeneration branch pipe through its second inlet and second outlet. The regeneration system also includes a dehumidification module humidity detection sensor arranged at the outlet ends of the first dehumidification module and the second dehumidification module.

[0025] In this way, when the humidity sensor of the dehumidification module detects that the dehumidification module is saturated with water content and cannot achieve the dehumidification effect, the regeneration system is controlled to operate. Part of the air flow enters the regeneration pipeline, is heated in the collector to form hot air, and then the hot air is controlled to enter the dehumidification module that needs to be regenerated to dry and regenerate the dehumidification module. Then, the high-humidity air flow after drying is sent outdoors for discharge. When the dehumidification module is regenerated, the dehumidification work of this module can be controlled to stop first. After the drying and regeneration are completed, it is put back into dehumidification use again. This enables the dehumidification module to be reused in a cyclic manner, ensuring long-term dehumidification effect.

[0026] Furthermore, a thermoelectric cooler is provided on the window body. The hot end of the thermoelectric cooler is connected to the collector to supply heat to it, and the cold end of the thermoelectric cooler is connected to the cold accumulator. The cold accumulator is connected to the surface cooler through a cooling water circulation pipeline for heat exchange and cooling supply.

[0027] In this way, the thermoelectric cooler is ingeniously used to supply heat and cooling to the collector and the surface cooler at the same time, which not only has a simple structure and is convenient for implementation, but also avoids energy waste and improves energy utilization efficiency.

[0028] As an optimization, a third bypass pipeline is also provided in the cascade dehumidification pipe network system. A fifth three-way valve is also provided at a position near the outlet of the second dehumidification module in the air flow channel. The starting end of the third bypass pipeline is connected to the fifth three-way valve, the outlet end of the third bypass pipeline is connected to the third inlet of the first dehumidification module, and a check valve is provided on the third bypass pipeline.

[0029] With the setting of the third bypass pipeline in this way, when any dehumidification module needs to participate in dehumidification again after drying and regeneration, it can be directly connected to the rear of the dehumidification module that is working for dehumidification without having to re-control the air flow to change the order. In this way, the conversion control to the high-efficiency dehumidification mode can be quickly completed, avoiding the wind force loss caused by the change of wind direction, improving the switching efficiency, and better meeting the user experience.

[0030] As an optimization, a set of cascade dehumidification pipe network system and the corresponding regeneration system are respectively provided in the window frames on both sides of the glass of the window body. The two cascade dehumidification pipe network systems share a surface cooler and the surface cooler is located in the window frame above the glass. The two regeneration systems share a collector and the collector is located in the window frame above the glass; the powers of the four dehumidification modules in the two cascade dehumidification pipe network systems are different from each other.

[0031] In this way, an additional set of cascade dehumidification pipe network system with different dehumidification effects is added, greatly improving the dehumidification gradient of the window. The four dehumidification modules can be combined respectively to achieve more than ten different sizes of dehumidification gradient control. At the same time, it has the advantages of reasonable and reliable structural arrangement and can avoid mutual interference.

[0032] In summary, the present invention has a multi-stage dehumidification gradient adjustment function, which can better adjust the dehumidification effect according to needs, improve the comfort of the outgoing air, and at the same time, it does not rely on external power and can work independently with good applicability.

[0036] The present invention will be further described in detail below in conjunction with the specific embodiments.

[0037] Specific embodiment: A stepped dehumidification window installed on the wall of a room first cools the fresh air entering the window so that the water vapor in the fresh air condenses, and then controls the air flow to pass through the dehumidification module to remove the condensed moisture and then send it into the room. Among them, at least two dehumidification modules are arranged in the window. After the fresh air enters, its humidity value is detected, and according to the humidity situation of the fresh air, it is controlled that the fresh air only passes through one dehumidification module or passes through more than one dehumidification module for dehumidification.

[0038] In this way, the dehumidification degree can be controlled according to the humidity situation of the fresh air, which can better avoid the situation of insufficient dehumidification or excessive dehumidification, and ensure better comfort of the outgoing air. The dehumidification module can be a container filled with a dehumidification solution (the dehumidification solution can be one solution or a mixture of multiple solutions among lithium bromide solution, calcium chloride solution, and lithium chloride solution), or a module with a ventilation effect made of a solid water-absorbing material. The specific implementation method is the prior art and will not be elaborated here.

[0039] In this embodiment, at least one low-power dehumidification module and one high-power dehumidification module are arranged in the window. During dehumidification, after detecting the humidity of the fresh air, it is compared with a preset threshold range. When the humidity of the fresh air is less than the preset threshold range, the air flow is controlled to only pass through the low-power dehumidification module. When the humidity of the fresh air falls within the preset threshold range, the air flow is controlled to only pass through the high-power dehumidification module. When the humidity of the fresh air is greater than the preset threshold range, the air flow is controlled to pass through the low-power dehumidification module and the high-power dehumidification module in sequence.

[0040] In this way, the dehumidification effects of three different levels can be achieved by relying on two dehumidification modules, and selection can be made better according to needs. The low-power dehumidification module refers to the dehumidification module with relatively lower dehumidification effect, and the high-power dehumidification module refers to the dehumidification module with relatively higher dehumidification effect, which can be specifically achieved by increasing or decreasing the volume of the dehumidification module, making one larger than the other. The specific size of the preset threshold range can also be set according to needs and will not be elaborated here.

[0041] Specifically, this method is achieved by installing a stepped dehumidification window on the wall of the room. Refer to Figures 1-3 , the stepped dehumidification window includes a window body 1. A wind flow channel 2 (the wind flow channel 2 is represented by solid lines) that is connected to the outside and inside of the window is provided on the window body. A fan 3 is installed at the inlet position inside the wind flow channel. A surface cooler 4 and an inlet air humidity sensor 5 are provided at a position near the inlet end of the wind flow channel. A stepped dehumidification pipe network system is formed in the wind flow channel. The stepped dehumidification pipe network system includes a first dehumidification module 6 and a second dehumidification module 7 arranged in series. The dehumidification effect of the first dehumidification module 6 is less than that of the second dehumidification module 7. A first bypass pipe is arranged in parallel beside the first dehumidification module 6, and a second bypass pipe is arranged in parallel beside the second dehumidification module 7. A first three-way solenoid valve 8 is further provided at the inlet end of the first dehumidification module. The three interfaces of the first three-way solenoid valve 8 are respectively connected to the pipeline at the inlet end of the stepped dehumidification pipe network system, the inlet end of the first bypass pipe, and the first inlet of the first dehumidification module 6. A second three-way solenoid valve 9 is further provided at the outlet end of the first dehumidification module 6. The three interfaces of the second three-way solenoid valve 9 are respectively connected to the first outlet of the first dehumidification module 6, the first inlet of the second dehumidification module 7, and the inlet of the second bypass pipe. It further includes a controller 10, and the controller 10 is respectively connected to the inlet air humidity sensor, the first three-way solenoid valve, the second three-way solenoid valve, and other components that need electrical control.

[0042] In this way, this method can be achieved by relying on this stepped dehumidification window. When the window is in use, the air flow is cooled and condensed by the surface cooler, and then the humidity situation is detected by the humidity sensor. According to the humidity situation, the air flow can be specifically controlled to pass through only the first dehumidification module or the second dehumidification module or both dehumidification modules at the same time, achieving the dehumidification effects of three gradients. The dehumidification module can be a container filled with a dehumidification solution (the dehumidification solution can be one solution or a mixture of multiple solutions among lithium bromide solution, calcium chloride solution, and lithium chloride solution), or a module made of solid water-absorbing material with ventilation effect, such as silica gel, molecular sieve, activated alumina, or composite solid dehumidification material.

[0043] Among them, the outlet end of the first bypass pipe is connected to the inlet end of the second dehumidification module 7, and a short-circuit pipe with a switching valve is further provided on the first bypass pipe and connected between the first dehumidification module 6 and the second three-way solenoid valve 9.

[0044] In this way, when dehumidification is not needed, the wind flow can bypass the two dehumidification modules and directly enter the room for ventilation. In addition, during implementation, a switch valve can be set on the pipeline as needed to strengthen the control of the wind flow direction.

[0045] An indoor humidity sensor 11 is also arranged on the inner side of the window body 1 .

[0046] In this way, the indoor humidity conditions can be detected. When the indoor humidity is too high, the dry air flow after deep dehumidification can be controlled to be introduced. When the indoor humidity is moderate, the dehumidification effect can be controlled to be adjusted to make it moderate.

[0047] Wherein, indoor humidity sensor 11 is arranged at the lower end position of the inner side of window body. This is because the indoor personnel activities are in the lower position of the room, and the wet air can sink at the same time, so the sensor is arranged at the lower end position to better realize detection.

[0048] The outer surface of the window body is also provided with a solar panel 12, which is connected to a battery 14 via a charge and discharge controller 13, and the battery 14 is connected to the controller 10. During implementation, the battery is connected to each electrical component that needs to be powered, and the controller is connected to each electrical component that needs to be controlled.

[0049] In this way, the solar panel can absorb solar energy to charge the battery, and then power the controller and other electrical components. This makes the dehumidification work independent of external power, thus improving applicability.

[0050] The upper end of the solar panel 12 is rotatably connected to the upper end of the outer side of the window body, and the window body is also provided with a rotatable support rod, which is used to open the solar panel 12 outward (see Figure 2 Schematic diagram).

[0051] In this way, the solar panels can better receive sunlight, absorb solar energy, and provide shade indoors.

[0052] The outlet of the wind channel is horizontally arranged in the middle of the window, and a shutter 15 is arranged at the outlet.

[0053] In this way, the air outlet direction can be adjusted through the blinds.

[0054] Among them, a regeneration system is also provided on the window body. The regeneration system includes a regeneration pipeline (the regeneration pipeline is represented by a dotted line in the figure). The main pipeline at the inlet end of the regeneration pipeline is connected to the air flow channel before entering the surface cooler 4. A collector 16 is arranged in the main pipeline at the inlet end of the regeneration pipeline. The regeneration system also includes a first regeneration branch pipe and a second regeneration branch pipe arranged in parallel. The inlet ends of the first regeneration branch pipe and the second regeneration branch pipe are connected to the main pipeline at the inlet end of the regeneration pipeline through a third three-way valve 17. The outlet ends of the first regeneration branch pipe and the second regeneration branch pipe are connected to the main pipeline at the outlet end of the regeneration pipeline through a fourth three-way valve 18. The main pipeline 19 at the outlet end of the regeneration pipeline is communicated with the outside of the window. The first dehumidification module 6 is connected to the first regeneration branch pipe through its second inlet and second outlet. The second dehumidification module 7 is connected to the second regeneration branch pipe through its second inlet and second outlet. The regeneration system also includes a dehumidification module humidity detection sensor arranged at the outlet ends of the first dehumidification module and the second dehumidification module. When the dehumidification module is a container of dehumidification solution, the dehumidification module humidity detection sensor can be equivalently replaced by a concentration sensor arranged in the dehumidification container.

[0055] In this way, when the dehumidification module humidity sensor detects that the dehumidification module is saturated with water content and cannot achieve the dehumidification effect, the regeneration system is controlled to work. Part of the air flow enters the regeneration pipeline, is heated in the collector to form hot air, and then the hot air is controlled to enter the dehumidification module that needs to be regenerated to dry and regenerate the dehumidification module. Then, the high-humidity air flow after drying is sent out of the room for discharge. When the dehumidification module is regenerated, the dehumidification work of this module can be controlled to stop first. After the drying regeneration is completed, it is put back into dehumidification use again. This enables the dehumidification module to be reused in a cycle, ensuring the long-term dehumidification effect.

[0056] Among them, a semiconductor refrigeration sheet 20 is arranged on the window body. The hot end of the semiconductor refrigeration sheet 20 is connected to the collector to supply heat to it. The cold end of the semiconductor refrigeration sheet is connected to a cold collector 21. The cold collector 21 is connected to the surface cooler 4 through a cooling water circulation pipeline to exchange heat and supply cold for it.

[0057] In this way, the semiconductor refrigeration sheet is cleverly used to supply heat and cold for the collector and the surface cooler at the same time, which not only has a simple structure and is convenient to implement, but also avoids energy waste and improves the energy utilization efficiency.

[0058] Among them, a third bypass pipeline is also arranged in the cascade dehumidification pipe network system. A fifth three-way valve 22 is also arranged at a position close to the outlet of the second dehumidification module in the air flow channel. The starting end of the third bypass pipeline is connected to the fifth three-way valve. The outlet end of the third bypass pipeline is connected to the third inlet of the first dehumidification module. A one-way valve 23 is arranged on the third bypass pipeline.

[0059] With the setting of the third bypass duct, when any dehumidification module needs to participate in dehumidification again after drying and regeneration, it can be directly connected to the rear of the working dehumidification module for dehumidification without re-controlling the air flow switching sequence. This can quickly complete the conversion control to the high-efficiency dehumidification mode, avoid the wind loss caused by the air flow switching, improve the switching efficiency, and better meet the user experience.

[0060] Wherein, a set of stepped dehumidification pipe network system and a corresponding regeneration system are respectively arranged in the window frames on both sides of the glass of the window body. The two stepped dehumidification pipe network systems share a surface cooler, and the surface cooler is located in the window frame above the glass. The two regeneration systems share a collector, and the collector is located in the window frame above the glass. The powers of the four dehumidification modules in the two stepped dehumidification pipe network systems are different from each other.

[0061] In this way, a set of stepped dehumidification pipe network system with different dehumidification effects is added, greatly improving the dehumidification gradient of the window. The four dehumidification modules can be combined respectively to achieve more than ten different sizes of dehumidification gradient control. At the same time, it has the advantages of reasonable and reliable structural arrangement and can avoid mutual interference.
