Description

Technical Field

[0001] This utility model belongs to the field of solution-based dehumidification air conditioning technology, specifically relating to a return air device with filtration function for solution-based dehumidification air conditioning. Background Technology

[0002] Solution-based dehumidification air conditioning is an air conditioning technology based on the concept of independent temperature and humidity control. It utilizes a hygroscopic salt solution in direct contact with the air, leveraging the partial pressure difference of water vapor between the solution surface and the air to drive moisture transfer, thus achieving dehumidification or humidification of the air. Simultaneously, it completes humidity regulation, sterilization, dust removal, and energy recovery—a comprehensive air handling system. Its core principle is: high-concentration solution absorbs moisture while low-concentration solution releases moisture, combined with a heat pump-driven regenerative circulation to concentrate the solution. This overcomes the temperature and humidity coupling limitations of traditional air conditioning condensation dehumidification, significantly improving energy efficiency and eliminating mold growth problems caused by damp surfaces. The system consists of a solution-based dehumidification unit, a high-temperature cold source, and dry terminal units.

[0003] For example, the solution-based humidity-regulating and temperature-controlled fresh air conditioning unit with announcement number CN201582926U discloses and protects the principle of the solution-based humidity-regulating and temperature-controlled fresh air conditioning unit, and publicly explains the winter and summer operation modes of the fresh air conditioning unit. However, when performing air recovery, the air in the room needs to be drawn back to the solution-based humidity-regulating air conditioning unit through an air pump. This technical solution directly draws the air in the room back to the solution-based humidity-regulating air conditioning unit, which will also bring back the fine dust floating in the room air to the solution-based humidity-regulating air conditioning unit, thereby increasing the impurity content of the solution in the air conditioning unit. Over a long period of time, this can lead to blockages and other malfunctions inside the solution-based humidity-regulating air conditioning unit. Utility Model Content

[0004] To address the issue in existing technologies where airborne dust particles are introduced into the solution-based humidification air conditioner, thus affecting its normal operation, this invention provides a return air device with filtration function for solution-based humidification air conditioners. This device employs a filtration structure to adsorb airborne dust particles, preventing them from entering the air conditioner and ensuring its normal operation. The specific technical solution is as follows: A return air device with filtration function for solution-based humidification air conditioners includes: a solution-based humidification air conditioner body; a return air structure is installed on the upper wall of the body; a filtration structure is installed inside the filtration structure; and a power structure is installed on the rear wall of the filtration structure. The return air structure includes: a return air rigid duct, a return air pump, a return air hose, a return air hopper, and a limiting frame. The return air rigid duct is installed at the return air inlet of the body; the return air pump is installed outside the duct; one end of the return air hose is connected to the duct; the return air hopper is connected to the hose; and the limiting frame is installed outside the hopper.

[0011] This utility model discloses a return air device with filtration function for solution-based humidification air conditioners. Compared with the prior art, the beneficial effects are as follows: By improving the return air inlet of the solution-based humidification air conditioner, the device allows the air entering the air conditioner to be filtered once, and the fine dust in the air is adsorbed in the filter cotton, thereby ensuring the air conditioner is well-ventilated and reducing the failure rate. At the same time, the device has an automatic filter cotton replacement function.

[0017] The following are specific implementation cases and appendices. Figures 1-4 The present invention will be further described, but it is not limited to these embodiments. The present invention provides a technical solution: a return air device with filtration function for a solution humidification air conditioner, comprising: a solution humidification air conditioner body 1, a return air structure installed on the upper wall of the solution humidification air conditioner body 1, a filter structure installed inside the return air structure, and a power structure installed on the rear wall of the filter structure; the return air structure includes: a return air rigid pipe 2, a return air pump 3, a return air hose 4, a return air hopper 5, and a limiting frame 6; the return air rigid pipe 2 is installed at the return air inlet of the solution humidification air conditioner body 1, the return air pump 3 is installed outside the return air rigid pipe 2, one end of the return air hose 4 is connected to the return air rigid pipe 2, the return air hopper 5 is connected to the other end of the return air hose 4, the limiting frame 6 is installed outside the return air hopper 5, and a fixed support frame 14 is provided on the outside of the solution humidification air conditioner body 1, and four anti-slip seats are provided on the lower wall of the fixed support frame 14.

[0018] As a preferred embodiment, the filter structure further includes: six filter cotton mounting frames 7, a filter rotating seat 8, and a rotating shaft 9; the six filter cotton mounting frames 7 are respectively installed on the outer wall of the filter rotating seat 8, the rotating shaft 9 is installed on the rear wall of the filter rotating seat 8, the filter cotton mounting frames 7 are movably installed between the limiting frame 6 and the return air hopper 5, the six filter cotton mounting frames 7 are evenly installed on the outside of the filter rotating seat 8, and the angle between two adjacent filter cotton mounting frames 7 is the same, and a soft sealing layer is attached to the outside of the six filter cotton mounting frames 7.

[0019] As a preferred embodiment, the power structure further includes: a power base 10, a reducer 11, and a power motor 12; the power base 10 is movably mounted on the outside of the rotating shaft 9 via bearings, the output end of the reducer 11 is mounted on the tail of the rotating shaft 9, the power motor 12 is mounted on the side wall of the power base 10, and the drive end of the power motor 12 is connected to the input end of the reducer 11; a dustproof protective cover 13 is installed at the front end of the power base 10, and the dustproof protective cover 13 covers the six filter cotton mounting frames 7 and the filter rotating seat 8, and the dustproof protective cover 13 is fixedly connected to the return air hopper 5.

[0020] Working principle: The operator first installs the solution humidification air conditioner body 1 in the designated position using the fixed support frame 14, and connects the external AC power supply to the solution humidification air conditioner body 1 to provide power for its operation. The working power of the return air pump 3 is provided by the solution humidification air conditioner body 1. Then, the operator fixes the power base 10 to the wall using expansion screws, and connects the external AC power supply to the power motor 12 to provide power for the operation of the power motor 12. The matching controller is also connected to the power motor 12 to provide control and working logic for the operation of the power motor 12.

[0021] Next, the operator removes the cover plate of the dustproof protective cover 13, then installs the air filter cotton used to filter impurities in the air into the six filter cotton mounting frames 7, and then installs the cover plate of the dustproof protective cover 13 back into its original position. At this point, the preparation work before using this device is completed.

[0022] When using this system, the solution-based humidifier unit 1 starts operating, and simultaneously, the return air pump 3 begins operation. The return air pump 3 creates a certain negative pressure, causing room air to pass through the filter cotton in the filter cotton mounting frame 7 and enter the return air duct 5. From there, it passes through the return air hose 4 and the return air rigid pipe 2 before entering the solution-based humidifier unit 1. As the air passes through the filter cotton in the filter cotton mounting frame 7, fine dust particles are filtered out, ensuring the purity of the solution inside the solution-based humidifier unit 1.

[0023] Simultaneously, when the filter cotton in a set of filter cotton mounting frames 7 has been used for a specified period of time, such as fifty hours, it needs to be replaced with new filter cotton to ensure filtration efficiency. First, the power motor 12 starts rotating, driving the rotating shaft 9 to rotate via the reducer 11. The reducer 11 reduces the output speed of the power motor 12, thereby increasing its output torque. Furthermore, the power motor 12 is a servo brake motor, and the controller can control the number of rotations of the power motor 12, thus controlling the rotation angle of the rotating shaft 9 and the filter rotating seat 8. The filter rotating seat 8 rotates the six filter cotton mounting frames 7. When the filter rotating seat 8 rotates to the next station, the next set of filter cotton mounting frames 7 carries new filter cotton into the space between the return air hopper 5 and the limit frame 6, thus completing the replacement of the new filter cotton. The filter cotton mounting frames 7 are coated with a soft sealing layer, such as a rubber coating, to improve the sealing effect.
