Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification devices, in particular to a rotary dehumidification system without a regeneration air duct. Background Art

[0002] In many scenarios, refrigerated dehumidifiers are needed to cool and dehumidify, thereby outputting dry air. For example, in the underground powerhouse of a hydropower station, the space environment is humid and low in temperature, and the water source used is often groundwater, which has a low water temperature, so dehumidification and cooling are required. At present, for such environments, the rotary dehumidification system is a common solution. Traditional rotary dehumidification systems often require the use of air ducts to reintroduce regenerated air into the room. Due to the need for air ducts, the structure is more complicated and requires a larger space, which is not applicable in scenarios with limited space.

[0003] In addition, the existing rotary dehumidification system often cannot adjust the heat input of the condenser in the patented dehumidification system, thus affecting the dehumidification and temperature control effect and maintaining the accurate dehumidification and temperature control state for a long time. In addition, the existing rotary dehumidification system often cannot perform different dehumidification working modes according to the different water content at the upper air outlet, and has poor adaptability to scenarios, and the user experience needs to be improved.

[0006] An air inlet path and a regeneration air path are also provided, and an electric heater and a rotary dehumidifier are sequentially provided along the wind direction of the regeneration air path.

[0007] The rotary dehumidifier spans the air inlet path and the regeneration air path, and the wind directions of the air inlet path and the regeneration air path are exactly opposite; and along the wind direction, the end of the regeneration air path merges with the front end of the air inlet path, and the front end of the regeneration air path merges with the end of the air inlet path, so that a part of the air at the output end of the air inlet path enters the regeneration air path, and the air at the output end of the regeneration air path enters the air inlet path.

[0008] The fin-type condenser is located on the regeneration air path, and the fin-type evaporator is located on the air inlet path or the regeneration air path, and can be switched between the two paths.

[0009] Furthermore, it also includes a proportional integral three-way water valve, a water inlet pipe and a water outlet pipe. The first end of the proportional integral three-way water valve and the refrigerant inlet of the water-cooled condenser are both connected to the outlet of the water inlet pipe, the second end of the proportional integral three-way water valve and the refrigerant outlet of the water-cooled condenser are connected, and the third end of the proportional integral three-way water valve is connected to the water outlet pipe.

[0012] Furthermore, the output end of the finned condenser is also connected to the input end of the finned evaporator through a second pipeline, and one end of the second pipeline close to the water-cooled condenser is connected to the pipeline where the drying filter is located.

[0013] Furthermore, the finned evaporator is located at the end of the regeneration air path, the finned condenser is located at the front end of the regeneration air path, and on the air inlet path, the finned condenser is located at the front end of the first blower, and the second blower is located at the rear end of the finned evaporator.

[0014] Furthermore, the upper air port on the air inlet path is located outside the regeneration air path, and external air can enter the air inlet path through the upper air port. The air inlet path and the regeneration air path are ducts or spaces where air can circulate.

[0015] Furthermore, a second pressure sensor is installed on the communication path between the refrigeration compressor and the finned condenser.

[0016] Furthermore, a solenoid valve is installed on the second pipeline, and the solenoid valve is located on a side close to the water-cooled condenser.

In addition, the utility model can also adjust the position of the finned evaporator according to the moisture content of the use environment, so as to adapt to different scene requirements and improve user experience.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific implementation plans:

[0027] Embodiment 1

[0028] like Figure 1-Figure 2As shown, a rotary dehumidification system without regeneration air duct includes a proportional integral three-way water valve 7, a water-cooled condenser 18, a first blower 12, a second blower 19, a finned evaporator 17, a rotary dehumidifier 16, an electric heater 15, a refrigeration compressor 14 and a finned radiator 13. The first end of the proportional integral three-way water valve 7 and the refrigerant inlet of the water-cooled condenser 18 are both connected to the outlet of the water inlet pipe, and the inlet of the water inlet pipe is used to access an external water source, such as groundwater with a relatively low water temperature (11-25°C). The second end of the proportional integral three-way water valve 7 is connected to the refrigerant outlet of the water-cooled condenser 18, and the third end of the proportional integral three-way water valve 7 is connected to the outlet pipe to discharge the water flow through the outlet pipe. The output end of the water-cooled condenser 18 is connected to the input end of the finned evaporator 17 through a pipeline, and the output end of the finned evaporator 17 is connected to the input end of the refrigeration compressor 14 through the first pipeline 1. The output end of the refrigeration compressor 14 is connected to the input end of the finned condenser, and the output end of the finned condenser is connected to the input end of the water-cooled condenser 18 through the second pipeline 2 .

[0029] In an optional embodiment, a one-way valve 9, a drying filter 10 and a throttling expansion valve 11 are sequentially installed on the pipeline connecting the water-cooled condenser 18 and the finned evaporator 17.

[0030] The drying filter 10 is used to filter impurities and absorb moisture, and the throttling expansion valve 11 is used for throttling. A one-way valve 9 is also installed on the communication path, and the one-way valve 9 is located on one side of the communication path close to the output end of the water-cooled condenser 18.

[0031] The input end of the filter drier 10 is provided with a coarse metal mesh, and the outlet end is provided with a fine metal mesh, so that larger particles of impurities can be effectively filtered out, and a desiccant with excellent moisture absorption properties is placed between the two metal meshes to absorb moisture in the refrigerant output from the output end of the water-cooled condenser 18, so as to ensure that the communication path is unobstructed and the refrigerant can be used normally in the subsequent finned evaporator 17. The communication path can be a capillary tube or other types of pipelines.

[0032] The throttling expansion valve 11 plays a throttling role by adjusting the flow rate, which can convert the high-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure mist refrigerant, creating conditions for the evaporation of the refrigerant. It can also automatically adjust the refrigerant flow entering the evaporator according to the heat signal obtained by the temperature sensor 5 to adapt to the change of the refrigeration load. At the same time, it can also maintain the superheat. By adjusting the flow rate, it can keep the evaporator within a certain superheat range to prevent abnormal overheating.

[0033] In an optional embodiment, the output end of the finned condenser is also connected to the input end of the finned evaporator 17 through the second pipeline 2, and the end of the second pipeline 2 close to the water-cooled condenser 18 is connected to the pipeline where the filter drier 10 is located, thereby connecting the second pipeline 2 to the input end of the finned evaporator 17. That is, the pipeline portion where the filter drier 10 is located in the pipeline where the water-cooled condenser 18 is connected to the finned evaporator 17 is connected to the second pipeline 2, thereby connecting the finned condenser to the finned evaporator 17.

[0034] The rotary dehumidifier 16 spans the air inlet path and the regeneration air path, and the wind directions of the air inlet path and the regeneration air path are opposite to each other. Along the wind direction, the end of the regeneration air path merges with the front end of the air inlet path, and the front end of the regeneration air path merges with the end of the air inlet path, so that a part of the air (i.e., the flowing wind) at the output end of the air inlet path enters the regeneration air path, and the air at the output end of the regeneration air path enters the air inlet path.

[0035] refer to Figure 1 , A→C→E→F is the air inlet path, and N→O→P→Q→B in the figure is the regeneration air path.

[0036] The humidity content of the air at A is greater than the humidity content of the air at B. The air at A is external air before being processed, and the air at B is air delivered from the second air blower 19 after being processed.

[0037] The finned evaporator 17 and the finned condenser are both located on the regeneration air path, the finned evaporator 17 is located at the end of the regeneration air path, and the finned condenser is located at the front end of the regeneration air path. On the air inlet path, the finned condenser is located at the front end of the first air supply fan 12, that is, the finned condenser is closer to the front end of the air inlet path than the first air supply fan 12, and the second air supply fan 19 is located at the rear end of the finned evaporator 17, that is, closer to the end of the regeneration air path.

[0038] An electric heater 15 and a rotary dehumidifier 16 are sequentially arranged along the wind direction of the regeneration air path (i.e., the air flow direction), so that the air flowing out of the fin-type condenser is first heated by the electric heater 15 and then blown into the rotary dehumidifier 16. The air flowing out of the rotary dehumidifier 16 after being processed is blown toward the fin-type evaporator 17, and the air flowing out of the fin-type evaporator 17 is finally sent into the air inlet path after passing through the second air supply fan 19 and mixed with the air on the air inlet path, thereby forming circulating air.

[0039] The upper air port on the air inlet path is located outside the regeneration air path, and external air can enter the air inlet path through the upper air port. The air inlet path can be a duct or a space where air can circulate formed by a building (such as a room), and the same is true for the regeneration air path, and the circulating air can be achieved without the aid of a regeneration air duct.

[0040] In an optional embodiment, a second pressure sensor 4 is further installed on the communication path between the refrigeration compressor 14 and the finned condenser.

[0041] In an optional implementation, a solenoid valve 8 is further installed on the second pipeline 2 , and the solenoid valve 8 is located on a side close to the water-cooled condenser 18 .

[0042] In an optional embodiment, a temperature sensor 5 and a third pressure sensor 6 are also installed on the water outlet pipe, and the temperature sensor 5 and the third pressure sensor 6 are directly or indirectly electrically connected to the proportional-integral three-way water valve 7 .

[0043] In an optional implementation, a first pressure sensor 3 is further installed on the first pipeline 1 , and the first pressure sensor 3 is located on a side close to the refrigeration compressor 14 .

[0044] Figure 2 The processed intake air refers to the air entering from point A (i.e., the upwind port), and the processed supply air refers to the air output after being processed by the first blower 12 (i.e., the air at point F).

[0045] Embodiment 2

[0046] refer to Figure 3-Figure 4 The only difference between this embodiment and the first embodiment is that the position of the finned evaporator 17 is different, and the rest is exactly the same as the first embodiment.

[0047] In this embodiment, the finned evaporator 17 is located on the air inlet path, and is located on the air inlet path after the air inlet path and the regeneration air path are mixed. Figure 3 In the figure, the finned evaporator 17 is located between points C and D of the air inlet path.

[0048] The difference between the finned evaporator 17 being located on the air inlet path and the finned evaporator 17 being located on the air inlet path is that the finned evaporator 17 located on the air inlet path can cool down and dehumidify the air mixed with the regeneration air and the humid air entering from the upwind port, and then enter the rotary dehumidifier 16, which has a better drying effect. However, the power of the finned evaporator 17 needs to be greater (i.e., the power of the host is greater), because it not only cools down the regeneration air, but also dehumidifies the humid air (i.e., the air entering from point A), so a finned evaporator 17 with greater power is required. For the finned evaporator 17 located on the regeneration air path, it only dehumidifies the regeneration air, which is suitable for processing areas with low moisture content in the inlet air. There is no need to cool down and dehumidify the air entering from the upwind port, and the power of the finned evaporator 17 is lower. Therefore, the first and second embodiments can be determined according to the scenario, and only the finned evaporator 17 needs to be moved to the corresponding position.

[0049] Therefore, the finned evaporator 17 can be switchably located on the air inlet path or the regeneration air path, so that it can be located on the air inlet path or on the regeneration air path respectively.

[0050] The utility model sets the position and connection relationship between the finned evaporator 17, the rotary dehumidifier 16, the finned condenser, the air inlet path and the regeneration air path, so that the rotary dehumidifier 16 processes the air on the air inlet path and then sucks it into the regeneration air path again by the finned condenser, thereby eliminating the need to set up a regeneration air duct, saving hardware costs and reducing occupied space. In addition, the utility model can also adjust the position of the finned evaporator 17 according to the moisture content of the use environment, so as to adapt to different scene requirements and improve user experience.

[0051] The embodiment disclosed in this specification is only an example of the unilateral features of the utility model, and the protection scope of the utility model is not limited to this embodiment. Any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
