Description

Technical Field

[0001] This utility model belongs to the field of dehumidifiers, specifically relating to a dehumidification device based on an air source heat pump. Background Technology

[0002] As is well known, a dehumidifier is a widely used fresh air device used to dry incoming humid air.

[0003] Currently, dehumidifiers include a regenerating fan, an electric heating module, a regenerating impeller, and a drainage structure. When external humid air enters the dehumidifier, the moisture contained in the humid air is adsorbed by a localized area of ​​the regenerating impeller, achieving a drying effect. Then, the regenerating fan blows airflow towards this localized area of ​​the regenerating impeller. This airflow flows through the electric heating module and is heated by the electric heating module. This heated airflow evaporates the moisture in the regenerating impeller and blows it out to the drainage structure, allowing the regenerating impeller to return to its state before the next adsorption. In other words, through the continuous rotation of the regenerating impeller, the process of adsorbing and evaporating moisture is repeated, and the external humid air is continuously dried.

[0004] However, this method has the following drawbacks: external humid gas directly enters the regeneration rotor for adsorption, which may lead to over-adsorption when the external gas humidity is high. In other words, the regeneration rotor cannot effectively adsorb all the moisture in the humid gas, so the drying effect cannot be achieved as expected. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a dehumidification device based on an air source heat pump. Before the regenerating rotor dries the humid air, cold water supplied by an external air source heat pump is used as a refrigerant to condense and pre-dry the humid air, thereby significantly improving the dehumidification effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A dehumidification device based on an air source heat pump is used to dry incoming humid air and output dry air. It is characterized by comprising: a housing with an inlet and an outlet, wherein the direction from the inlet to the outlet within the housing is defined as the drying direction; humid air enters through the inlet and dry air exits through the outlet; a molecular sieve rotor rotatably disposed inside the housing; a condenser tube assembly and a regeneration assembly; the condenser tube assembly and the molecular sieve rotor are sequentially arranged along the drying direction; the molecular sieve rotor has a dehumidification zone and a regeneration zone that are cyclically converted by rotation; humid air passes through the dehumidification zone and is adsorbed to form dry air; the regeneration assembly includes a regeneration fan that blows hot air toward the regeneration zone, the hot air evaporating and blowing out the moisture in the regeneration zone; wherein the condenser tube assembly includes a water-receiving shell and a coiled condenser tube fixed inside the water-receiving shell; the water-receiving shell is fixed inside the housing; the coiled condenser tube is hollow and its outer surface is continuous with the inner wall of the water-receiving shell; the coiled condenser tube is connected to the cold water supply end of an external air source heat pump through an internal channel of the water-receiving shell.

[0008] Preferably, both ends of the coiled condenser tube are connected to the external air source heat pump through the internal channels of the water-receiving shell. Thus, cold water continuously flows into the coiled condenser tube from the air source heat pump as a refrigerant to exchange heat and condense the humid air flowing through it. The heated cold water in the coiled condenser tube finally flows back to the air source heat pump.

[0009] Preferably, the present invention further includes an internal support and a drive motor. The internal support is fixed inside the housing. The axes of the drive motor and the molecular sieve rotor are parallel and rotatably mounted on the internal support. A tension wheel is fixed on the output shaft of the drive motor. The tension wheel and the molecular sieve rotor are synchronously driven by a synchronous belt.

[0010] Preferably, the regeneration assembly further includes a regeneration housing and a heating wire. One end of the regeneration housing covers the regeneration area, and the other end communicates with the outside of the housing. The heating wire and the regeneration fan are both located inside the regeneration housing. The heating wire is used to heat the air inside the regeneration housing, and the regeneration fan is used to blow the heated air across the regeneration area.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Because the dehumidification device based on the air source heat pump of this utility model includes a casing, a molecular sieve rotor, a condenser tube assembly, and a regeneration component, the casing has a drying direction, the molecular sieve rotor has a dehumidification area and a regeneration area that are switched by rotation, the regeneration component includes a regeneration fan that evaporates and blows out the moisture in the regeneration area, and the condenser tube assembly includes a water-receiving shell and a coiled condenser tube fixed in the water-receiving shell. The coiled condenser tube is hollow and its outer surface is continuous with the inner wall of the water-receiving shell. The coiled condenser tube is connected to the cold water supply end of the external air source heat pump through the internal channel of the water-receiving shell. Therefore, before the molecular sieve rotor dries the humid air, this utility model uses the cold water provided by the external air source heat pump as a refrigerant and condenses and pre-dries the humid air to be dried through the coiled condenser tube, thereby significantly improving the dehumidification effect.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate the dehumidification device based on an air source heat pump of this utility model. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0018] like Figure 1 As shown, the dehumidification device 100 based on the air source heat pump in this embodiment is used to dry the incoming humid air and output dry air.

[0019] The dehumidification device 100 based on an air source heat pump includes a housing 10, a drive motor 20, a molecular sieve rotor 30, a condenser tube assembly 40, and a regeneration component 50.

[0020] The housing 10 has an inlet 11 and an outlet 12. The direction from the inlet 11 to the outlet 12 inside the housing 10 is taken as the drying direction. Humid air enters from the inlet 11 and dry air is output from the outlet 12. Specifically, the inlet 11 is also provided with a guide fan 13, so that the humid airflow can form a stable and continuous flow direction along the drying direction after entering.

[0021] The drive motor 20, molecular sieve rotor 30, condenser tube assembly 40 and regeneration component 50 are all located inside the casing 10, and the condenser tube assembly 40 and molecular sieve rotor 30 are arranged sequentially along the drying direction, so that the airflow inside the casing 10 continuously flows through the condenser tube assembly 40 and molecular sieve rotor 30 in sequence.

[0022] An internal support (not shown in the attached drawings) is provided inside the housing 10. The axes of the drive motor 20 and the molecular sieve rotor 30 are parallel and rotatably mounted on the internal support. A tension wheel (not shown in the attached drawings) is fixed on the output shaft of the drive motor 20. The circumference of the tension wheel and the circumference of the molecular sieve rotor are synchronously driven by a synchronous belt. Thus, the drive motor 20 drives the molecular sieve rotor 30 to rotate. In this embodiment, the drying direction is perpendicular to the molecular sieve rotor 30.

[0023] The molecular sieve rotor 30 has a dehumidification zone 31 and a regeneration zone 32 that are cyclically switched by rotation. Moist air passes through the dehumidification zone 31 and is adsorbed with moisture to form dry air. Specifically, in order to continue to use the molecular sieve rotor 30, the molecular sieve rotor 30 should be evaporated and dehydrated after adsorbing moisture, so that the molecular sieve rotor 30 can return to a dry state and adsorb moisture from the humid air again. The positions of the dehumidification zone 31 and the regeneration zone 32 relative to the housing 10 remain unchanged. The molecular sieve rotor 30 rotates to cyclically switch between the dehumidification zone 31 and the regeneration zone 32.

[0024] like Figure 2 As shown, the condenser tube assembly 40 includes a water-receiving shell 41 and a coiled condenser tube 42 fixed inside the water-receiving shell 41.

[0025] The water-receiving shell 41 is fixed inside the housing 10. Specifically, the inner cavity of the water-receiving shell 41 is open upwards.

[0026] The coiled condenser tube 42 is hollow and its outer surface is continuous with the inner wall of the water-receiving shell 41. The coiled condenser tube 42 is connected to the cold water supply end P1 of the external air source heat pump through the internal channel of the water-receiving shell 41 (not shown in the figure).

[0027] Both ends of the coiled condenser tube 42 are connected to the external air source heat pump through the internal channels of the water-receiving shell 41. Thus, cold water continuously flows into the coiled condenser tube 42 from the air source heat pump as a refrigerant to exchange heat and condense the humid air flowing through it. The heated cold water in the coiled condenser tube finally flows back to the air source heat pump. Specifically, the outer surface of the casing 10 has two quick-connect connectors P3. The air source heat pump has a cold water supply end P1 and a cold water return end P2. The cold water supply end P1 is connected to a quick-connect plug P3, which is connected to one end of the coiled condenser tube 42. The other end of the coiled condenser tube 42 is connected to another quick-connect connector P3, which is connected to the cold water return end. In this embodiment, the temperature of the cold water flowing out of the air source heat pump is 3℃-7℃.

[0028] like Figure 3 As shown, the regeneration assembly 50 includes a regeneration housing 51, a regeneration fan 52, and a heating wire 53.

[0029] One end of the regeneration cover 51 is placed over the regeneration area 32, and the other end is connected to the outside of the housing 10.

[0030] The heating wire 53 and the regeneration fan 52 are both located inside the regeneration housing 51. The heating wire 53 is used to heat the air inside the regeneration housing 51, and the regeneration fan 52 is used to blow the heated air across the regeneration area 32. Specifically, the air flows through the heating wire 53 and the regeneration fan 52 in sequence inside the regeneration housing 51, that is, the regeneration fan 52 is closer to the regeneration area 32 inside the regeneration housing 51.

[0031] Specifically, the regeneration assembly 50 also includes a dehumidification channel 54. The dehumidification channel 54 and the regeneration housing 51 are located on opposite sides of the regeneration area 32. One end of the dehumidification channel 54 covers the regeneration area 32 and corresponds to the end of the regeneration housing 51. That is, the regeneration fan 52 blows hot air toward the regeneration area 32. The hot air evaporates the moisture in the regeneration area 32 containing moisture and blows it into the interior of the dehumidification channel 54. In this embodiment, the other end of the dehumidification channel 54 is open to the outside of the housing 10, that is, the gas mixed with moisture is discharged to the outside of the housing 10.

[0032] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
