Description

Technical Field

[0001] The utility model relates to the technical field of air treatment equipment, in particular to a dehumidification system. Background Art

[0002] In existing spaces such as office buildings, centralized office places or centralized meeting places, due to the concentration of people, the indoor carbon dioxide concentration will continuously increase. As the indoor carbon dioxide concentration rises, it may cause discomfort to the human body and affect the work efficiency of personnel. Therefore, existing spaces such as office buildings, centralized office places or centralized meeting places are provided with ventilation systems to replace the indoor air and reduce the indoor carbon dioxide concentration.

However, this supply air temperature will cause discomfort to the human body in summer or the plum rain season; if the supply air temperature of the ventilation system to the room is 23 - 25°C, it will cause an increase in indoor humidity, thereby causing discomfort to the human body.

Identical reference numerals in the figures denote identical or similar structures, and thus their repeated description will be omitted.

[0036] In the present utility model, the words expressing positions and directions are described by taking the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of the present utility model.

[0037] Embodiment 1

[0038] As Figure 1 and Figure 2 shown, the present utility model provides a dehumidification system, including a dehumidification wheel 1, an air supply flow path 2, a first evaporator 21, a second evaporator 22, a regeneration flow path 4, and a first condenser 41.

[0039] The dehumidification rotary wheel 1 can adopt the commonly used existing dehumidification rotary wheel 1. The dehumidification rotary wheel 1 includes a dehumidification area 11 and a regeneration area 12. The dehumidification area 11 can absorb the moisture in the air flowing through the dehumidification area 11 to reduce the air humidity; the regeneration area 12 can remove the moisture carried by itself under the action of high-temperature gas drying. When the dehumidification rotary wheel 1 works, it will rotate continuously, so that a part of the dehumidification rotary wheel 1 moves into the dehumidification area to form the dehumidification area 11 that absorbs moisture. Then, this part can further rotate to the regeneration area to form the regeneration area 12, and be dried in the regeneration area to remove the absorbed moisture.

[0040] The air supply flow path 2 is connected to the outside and the target space 3, so that the outside gas can flow into the air supply flow path 2 to form the treated air, and the treated air can flow from the air supply flow path 2 into the target space 3. Among them, the target space 3 can be a space that needs air treatment, such as indoor spaces like bedrooms, dormitories, office places, and leisure places. The treated air from the outside can be fresh air from the outside, and the fresh air from the outside is inhaled into the air supply flow path 2 to form the treated air. The air supply flow path 2 can pass through the first evaporator 21, the second evaporator 22, and the dehumidification area 11. Specifically, the first evaporator 21, the dehumidification area 11, and the second evaporator 22 can be arranged in sequence along the flow direction of the treated air, so that the treated air in the air supply flow path 2 flows through the first evaporator 21, the dehumidification area 11, and the second evaporator 22 in sequence.

[0041] The first evaporator 21 can be used to dehumidify the treated air. After the treated air is processed by the first evaporator 21, its temperature decreases and part of the water vapor in the treated air condenses to form condensed water and precipitates, thereby realizing the preliminary dehumidification of the treated air; the treated air flows to the dehumidification area 11 after being processed by the first evaporator 21, and the dehumidification area 11 dries the treated air. After the treated air is processed by the dehumidification area 11, its temperature rises and its humidity decreases; the treated air flows to the second evaporator 22 after being processed by the dehumidification area 11. After the treated air is processed by the second evaporator 22, its temperature decreases and its relative humidity increases. At this time, the temperature and humidity of the treated air are more appropriate, and the treated air can flow into the target space 3 after being processed by the second evaporator 22.

[0042] Specifically, the temperature of the outside air can be 35°C, the relative humidity can be 75%, and the moisture content can be 27 g / kg. The outside air is sucked into the supply air flow path 2 to form treated air. The temperature of the treated air after passing through the first evaporator 21 is 20°C, the relative humidity can be 95%, and the moisture content is 13.94 g / kg. Then, the temperature of the treated air after passing through the dehumidification zone 11 is 32°C, the relative humidity can be 26%, and the moisture content is 7.6 g / kg. The treated air flows to the second evaporator 22 and is treated by the second evaporator 22, and the temperature is 24°C, the relative humidity can be 41%, and the moisture content is 7.6 g / kg. At this time, the humidity and temperature of the treated air are relatively appropriate. Using this treated air to be sent into the target space 3 can improve the comfort of the people in the target space 3.

[0043] By adopting the cooperation of the first evaporator 21, the second evaporator 22 and the dehumidification rotor 1, it is possible to control the humidity of the treated air while cooling the treated air, so that the temperature and humidity of the treated air are relatively appropriate after passing through the first evaporator 21, the second evaporator 22 and the dehumidification rotor 1. Using the treated air with relatively appropriate humidity and temperature to be supplied into the target space 3 can make the environment in the target space 3 relatively appropriate and improve the comfort of the people in the target space 3.

[0044] In some specific embodiments, to prevent impurities such as dust particles contained in the treated air inhaled from the outside from flowing into the room or the first evaporator 21 through the supply air flow path 2, the supply air flow path 2 can flow through the first filter 24, and the first filter 24 can be used to filter impurities such as dust particles in the treated air. Among them, the first filter 24 can be arranged upstream of the first evaporator 21 along the flow direction of the treated air, so that the treated air flows to the first evaporator 21 after being filtered by the first filter 24. The first filter 24 can be an existing air filter.

[0045] When the treated air is treated by the first evaporator 21, as the temperature of the treated air decreases, the water vapor in the treated air will condense to form condensate. To prevent the condensate generated at the first evaporator 21 from splashing onto the dehumidification rotor 1 when dripping or being blown towards the dehumidification rotor 1 along with the flow of the treated air, a water baffle 25 is arranged between the first evaporator 21 and the dehumidification rotor 1, and the water baffle 25 can be used to block the condensate generated at the first evaporator 21 from contacting the dehumidification rotor 1.

[0046] To prompt the processed air to flow towards the target space 3 within the supply air flow path 2, a processed air blower 23 may be provided within the supply air path. The processed air blower 23 can drive the flow of the processed air, thereby prompting the processed air to flow through the first filter 24, the first evaporator 21, the water baffle 25, the dehumidification zone 11, the second evaporator 22 in sequence, and flow towards the target space 3. Specifically, the processed air blower 23 may be disposed downstream of the dehumidification zone 11 along the flow direction of the processed air and upstream of the second evaporator 22 along the flow direction of the processed air.

[0047] The regeneration flow path 4 is used for the flow of the regeneration air, and the regeneration flow path 4 passes through the regeneration zone 12 so that the regeneration air can dry the regeneration zone 12. The regeneration flow path 4 may pass through the first condenser 41 and the regeneration zone 12 in sequence. The regeneration air within the regeneration flow path 4 is heated by passing through the first condenser 41 and then flows towards the regeneration zone 12 to dry the regeneration zone 12.

[0048] Specifically, when the regeneration air starts to flow into the regeneration flow path 4, its temperature may be 35°C, the relative humidity may be 75%, and the moisture content may be 27 g / kg. After being processed by the first condenser 41, the temperature of the regeneration air is 55°C, the relative humidity may be 27%, and the moisture content is 27 g / kg. At this time, the regeneration air can flow towards the regeneration zone 12 to heat the regeneration zone 12, thereby removing at least part of the moisture within the regeneration zone 12. The part of the dehumidification wheel 1 located within the regeneration zone 12 and processed by the regeneration air can rotate into the dehumidification zone 11 to dehumidify the processed air.

[0049] In some specific embodiments, the first condenser 41 may be connected to the first evaporator 21 and / or the second evaporator 22. When the refrigerant flows through the first condenser 41, it condenses and generates condensation heat to heat the regeneration air. After that, the refrigerant expands through the expansion valve and then flows through the first evaporator 21 and / or the second evaporator 22 to absorb heat and evaporate to form a gaseous medium. This gaseous medium forms a high-temperature and high-pressure medium after being worked on by the compressor and flows into the first condenser 41 for condensation, cycling in sequence. By connecting the first condenser 41 to the first evaporator 21 and / or the second evaporator 22, the energy utilization rate in the dehumidification system can be improved, and the operating cost of the dehumidification system can be reduced.

[0050] Specifically, when the first condenser 41 is connected to the first evaporator 21, the first condenser 41 and the first evaporator 21 can be located on the same circulation flow path. A medium such as refrigerant circulates within this circulation flow path. When the medium flows to the first evaporator 21, it absorbs heat and evaporates to form a high-temperature low-pressure gaseous medium. When the medium absorbs heat in the first evaporator 21, it can absorb the heat of the treated air flowing through the first evaporator 21 to cool and dehumidify the treated air. Subsequently, this low-pressure gaseous medium will flow into the first condenser 41 for condensation and heat dissipation, thereby forming a low-temperature liquid medium. The heat dissipated by the medium in the first condenser 41 can heat the regeneration air flowing through the first condenser 41. The low-temperature liquid medium can continue to flow along the circulation flow path to the first evaporator 21 to form a high-temperature gaseous medium, and the cycle repeats. As a preferred method, a compressor and an expansion valve can also be provided on the circulation flow path. After the medium forms a low-pressure gaseous medium at the first evaporator 21, it will flow to the compressor. The compressor compresses the low-pressure gaseous medium to increase the pressure and temperature of the low-pressure gaseous medium. Therefore, when this gaseous medium condenses in the first condenser 41, it can release more heat, thereby heating the regeneration air more effectively. The low-temperature liquid medium formed by the medium in the first condenser 41 can flow to the expansion valve to expand, so as to reduce the pressure and temperature of the low-temperature liquid medium. Then, the low-temperature low-pressure liquid medium flows to the first evaporator 21 for evaporation.

[0051] When the first condenser 41 is connected to the second evaporator 22, the first condenser 41 and the second evaporator 22 are located on the same circulation flow path, and the structure is similar to that of the above-mentioned first condenser 41 and the first evaporator 21 located on the same circulation flow path, so it will not be elaborated here. When the first condenser 41 is connected to both the second evaporator 22 and the first evaporator 21, the first condenser 41, the second evaporator 22, and the first evaporator 21 are located on the same circulation flow path. The medium can respectively evaporate and absorb heat in the first evaporator 21 and the second evaporator 22, and after being compressed by the compressor, it flows to the first condenser 41 for condensation and heat dissipation.

[0052] According to actual needs and the actual installation positions of the first condenser 41, the first evaporator 21, and the second evaporator 22, the first condenser 41 can be located on the same circulation flow path only with the first evaporator 21, or only with the second evaporator 22, or can be located on the same circulation flow path with both the first evaporator 21 and the second evaporator 33 at the same time.

[0053] Refer to Figure 2 , one end of the regeneration flow path 4 can be connected to the target space 3 so that the gas in the target space 3 can be inhaled into the regeneration flow path 4 to form regeneration air; or, refer to Figure 1, one end of the regeneration flow path 4 can communicate with the outside world so that outside air can be inhaled into the regeneration flow path 4 to form a regeneration wind. To prevent impurities such as dust particles contained in the regeneration wind inhaled from the outside or the target space 3 from flowing through the air supply flow path 2 to the first condenser 41, the regeneration flow path 4 can flow through the second filter 44, and the second filter 44 is used to filter impurities such as dust particles in the regeneration wind. Among them, the second filter 44 can be arranged upstream of the first condenser 41 along the flowing direction of the regeneration wind so that the regeneration wind flows through the first condenser 41 after being filtered by the second filter 44. The second filter 44 can be an existing air filter.

[0054] In some specific embodiments, part of the condensation heat of the refrigeration system is dissipated through a refrigeration medium such as a refrigerant in the first condenser 41 to heat the regeneration wind so that the regeneration wind can dry the regeneration area 12. The remaining condensation heat needs to be dissipated to the outside to prevent excessive condensation heat from accumulating in the refrigeration system and affecting the operation of the dehumidification system; to dissipate the excessive condensation heat to the outside, the regeneration flow path 4 can flow through the second condenser 42, and the second condenser 42 can be connected to the first evaporator 21 and / or the second evaporator 22 so that the low-pressure gaseous medium in the first evaporator 21 and / or the second evaporator 22 flows to the second condenser 42 to dissipate heat after doing work by the compressor. The heat dissipated by the medium in the second condenser 42 can be used to heat the regeneration wind flowing through the second condenser 42, and the heated regeneration wind flows to the outside to dissipate the excessive condensation heat to the outside. Among them, the refrigeration system is composed of components such as an evaporator, a condenser, a compressor, an expansion valve, and a refrigeration medium.

[0055] Among them, when the second condenser 42 is connected to the second evaporator 22, the second condenser 42 and the second evaporator 22 can be located on the same circulation flow path, and a medium such as a refrigerant circulates in this circulation flow path. The medium absorbs heat and evaporates in the second evaporator 22 to form a low-pressure gaseous medium. When the medium absorbs heat in the second evaporator 22, it can absorb the heat of the treatment wind flowing through the second evaporator 22 to lower the temperature of the treatment wind; then this low-pressure gaseous medium flows to the second condenser 42 to condense and dissipate heat after doing work by the compressor, and the heat dissipated by the medium in the second condenser 42 can be absorbed by the regeneration wind flowing through the second condenser 42 and dissipated to the outside through the regeneration wind.

[0056] When the second condenser 42 is connected to the first evaporator 21, the second condenser 42 and the first evaporator 21 are on the same circulation flow path, and the structure is similar to that when the second condenser 42 and the second evaporator 22 are on the same circulation flow path, so it will not be elaborated here. When the second condenser 42 is connected to the second evaporator 22 and the first evaporator 21, the second condenser 42, the second evaporator 22 and the first evaporator 21 are on the same circulation flow path, and the medium can respectively evaporate and absorb heat in the first evaporator 21 and the second evaporator 22, and after being compressed by the compressor, flow to the second condenser 42 for condensation and heat dissipation.

[0057] Specifically, the second condenser 42 can be connected to one of the first evaporator 21 and the second evaporator 22 so that the gaseous medium formed by the corresponding evaporator flows to the second condenser 42 for condensation and heat dissipation after doing work by the compressor, and the first condenser 41 can be connected to the other of the first evaporator 21 and the second evaporator 22 so that the gaseous medium formed by the corresponding evaporator flows to the first condenser 41 for condensation and heat dissipation after doing work by the compressor. By using the first condenser 41 and the second condenser 42 to dissipate heat from the gaseous media generated by the corresponding evaporators respectively, it is possible to prevent the heat of the gaseous media formed in the first evaporator 21 and the second evaporator 22 from being directly dissipated, which may affect the operation of the dehumidification system. Among them, the second condenser 42 can be arranged downstream of the regeneration area 12 along the flowing direction of the regeneration air.

[0058] In some specific embodiments, a branch flow path 5 can be communicated with the regeneration flow path 4. One end of the branch flow path 5 is communicated with the outside, and the other end is communicated with the regeneration flow path 4; among them, the connection position of the branch flow path 5 and the regeneration flow path 4 can be located downstream of the regeneration area 12 along the flowing direction of the regeneration air and upstream of the second condenser 42 along the flowing direction of the regeneration air. The outside gas can flow into the regeneration flow path 4 from the branch flow path 5 and be mixed with the regeneration air dried by the regeneration area 12 to reduce the temperature of the regeneration air. Then, when the relatively low-temperature regeneration air flows to the second condenser 42, it can absorb more heat, thereby ensuring that the heat carried by the gaseous medium generated by the first evaporator 21 and / or the second evaporator 22 after doing work by the compressor can be fully dissipated in the second condenser 42. According to needs, a wind valve 51 can be arranged on the branch flow path 5, and the wind valve 51 can control the on-off of the branch flow path 5. When it is necessary to mix the outside air with the regeneration air heated by the regeneration area 12, the wind valve 51 can be opened to dredge the branch flow path 5; when it is not necessary to mix the outside air with the regeneration air heated by the regeneration area 12, the wind valve 51 can be closed, and at this time the branch flow path 5 is blocked.

[0059] To promote the flow of the regenerated air in the regeneration flow path 4, a regeneration air blower 43 may be provided in the regeneration flow path 4. The regeneration air blower 43 can drive the flow of the regenerated air, thereby promoting the regenerated air to flow through the second filter 44, the first condenser 41, the regeneration zone 12, the second condenser 42 in sequence, and flow to the outside. Specifically, the regeneration air blower 43 may be disposed downstream of the second condenser 42 along the flow direction of the regenerated air.

[0060] The above-mentioned air supply flow path 2 may be formed in a pipeline. The extending path of the pipeline can be set according to the actual installation space, and the first filter 24, the first evaporator 21, the water baffle 25, the dehumidifying rotor 1, the processing air blower 23, and the second evaporator 22 may be sequentially arranged along the extending direction of the air supply flow path 2. The regeneration flow path 4 may also be formed in a pipeline. The extending path of this pipeline can be set according to the actual installation space, and the second filter 44, the first condenser 41, the dehumidifying rotor 1, the second condenser 42, and the regeneration air blower 43 are sequentially arranged along the extending path of the regeneration flow path 4.

The first space 61, the third space 63, the second space 62, and the fourth space 64 may be sequentially arranged. The dehumidifying rotor unit 7 includes a first chamber 71 and a second chamber 72.

[0063] The first space 61 may accommodate the first evaporator 21, and one end of the first space 61 may communicate with the outside, so that outside air can enter the first space 61 to form processing air. The processing air can flow through the first evaporator 21 to enable the first evaporator 21 to cool the processing air. As a preferred method, a first filter 24 and a water baffle 25 are further provided in the first space 61, and the first filter 24, the first evaporator 21, and the water baffle 25 are sequentially arranged along the flow direction of the processing air, so that the processing air flows through the first filter 24, the first evaporator 21, and the water baffle 25 in sequence after flowing into the first space 61. Among them, the water baffle 25 is used to block the condensed water generated by the first evaporator 21 from flowing toward the dehumidification zone 11. In addition, an outlet is provided in the first space 61 in the downstream direction of the water baffle 25 along the flow direction of the processing air, and the processing air can flow out of the first space 61 from the outlet of the first space 61.

[0064] One end of the first chamber 71 can be directly or indirectly communicated with the outlet of the first space 61, so that the treatment air flowing out of the first space 61 can flow into the first chamber 71. The dehumidification zone 11 of the dehumidification rotor 1 can be accommodated in the first chamber 71. After the treatment air flows into the first chamber 71, it will flow through the dehumidification zone 11, so that the dehumidification zone can remove the moisture in the treatment air. As a preferred mode, a treatment air blower 23 is further arranged in the first chamber 71, and the treatment air blower 23 can drive the treatment air to flow along the air supply flow path 2. Among them, the treatment air blower 23 can be arranged upstream of the dehumidification zone 11 along the flowing direction of the treatment air. An outlet is arranged in the first chamber 71 in the downstream direction of the dehumidification zone 11 along the flowing direction of the treatment air, and the treatment air can flow out of the first chamber 71 from the outlet of the first chamber 71.

[0065] A second evaporator 22 is accommodated in the second space 62, and one end of the second space 62 can be directly or indirectly communicated with the outlet of the first chamber 71, so that the treatment air can further flow into the second space 62 after flowing out of the first chamber 71. After the treatment air flows into the second space 62, it will flow through the second evaporator 22, so that the second evaporator 22 can cool the treatment air. Among them, an outlet is arranged in the second space 62 in the downstream direction of the second evaporator 22 along the flowing direction of the treatment air, and the outlet of the second space 62 can be communicated with the target space 3, so that the treatment air can flow into the target space 3 after being processed by the second evaporator 22 to form appropriate humidity and temperature.

[0066] The above-mentioned first space 61, first chamber 71, and second space 62 are sequentially communicated to form an air supply flow path 2.

[0067] A first condenser 41 is accommodated in the third space 63, and one end of the third space 63 can be communicated with the target space 3 or the outside, so that the gas in the target space 3 or the outside gas can flow into the third space 63 to form a regeneration air flow. When the regeneration air flow flows in the third space 63, it will flow through the first condenser 41, so that the regeneration air flow can be heated by the first condenser 41. Among them, the third space 63 and the first space 61 are arranged adjacent to each other, and the first evaporator 21 in the first space 61 and the first condenser 41 in the third space 63 can be located in the same circulation flow path, and a medium such as a refrigerant circulates in the circulation flow path. The medium absorbs heat and evaporates in the first evaporator 21 to form a high-temperature low-pressure gaseous medium, so that the medium can absorb the heat of the treatment air flowing through the first evaporator 21; then the low-pressure gaseous medium forms a high-temperature high-pressure medium after doing work by the compressor and flows into the first condenser 41 for condensation and heat dissipation to form a low-temperature liquid medium. The heat dissipated by the medium in the first condenser 41 can be used to heat the regeneration air flow flowing through the first condenser 41. The low-temperature liquid medium formed after flowing through the first condenser 41 can flow into the first evaporator 21 through an expansion valve to absorb heat and evaporate.

[0068] As a preferred embodiment, a second filter 44 is further accommodated in the third space 63. The second filter 44 is disposed upstream of the first condenser 41 along the flowing direction of the regeneration air. The regeneration air can flow through the second filter 44 and the first condenser 41 in sequence in the third space 63. In addition, an outlet is provided in the third space 63 in the downstream direction of the first condenser 41 along the flowing direction of the regeneration air, and the regeneration air can flow out of the third space 63 from the outlet of the third space 63.

[0069] The regeneration area 12 of the dehumidifying rotor 1 is accommodated in the second chamber 72. One end of the second chamber 72 can be directly or indirectly communicated with the outlet of the third space 63, so that the regeneration air flowing out of the outlet of the third space 63 can flow into the second chamber 72. The regeneration air in the second chamber 72 can flow through the regeneration area 12, so that the regeneration air dries the regeneration area 12. In addition, a regeneration fan 43 can be provided in the second chamber 72. The regeneration fan 43 is used to drive the regeneration air to flow along the regeneration flow path 4. An outlet is provided in the second chamber 72 in the downstream direction of the regeneration fan 43 along the flowing direction of the regeneration air. The outlet of the second chamber 72 can be communicated with the outside, so that the regeneration air can be discharged to the outside from the outlet of the second chamber 72.

[0070] The above-mentioned third space 63 and the second chamber 72 are communicated to form a regeneration flow path 4.

[0071] In some specific embodiments, a second condenser 42 is accommodated in the fourth space 64. One side of the fourth space 64 is adjacent to the second space 62, and the other side is adjacent to the outside. Therefore, the second evaporator 22 in the second space 62 and the second condenser 42 in the fourth space 64 can be located in the same circulation flow path, and a medium such as a refrigerant circulates in the circulation flow path. The medium absorbs heat and evaporates in the second evaporator 22 to form a gaseous medium, and then flows into the second condenser 42 for condensation and heat dissipation. The heat dissipated by the medium in the second condenser 42 can be dissipated to the outside, thereby realizing the dissipation of the heat carried by the gaseous medium formed by the second evaporator 22 to the outside. In addition, the excess heat generated by other parts in the heat pump unit 6 can also be heat-transferred to the medium and then absorbed by the medium. After that, the medium flows into the second condenser 42 for heat dissipation, so that the second condenser 42 can receive the excess heat in the heat pump unit 6 and dissipate heat to the inside of the heat pump unit 6.
