Description

[0002] With people's increasing demands for indoor air quality, rotary dehumidifiers, as an effective air purification and humidity control device, have been widely used in many fields. A rotary dehumidifier is a machine that removes moisture from the air through the principle of physical adsorption, mainly relying on the internal honeycomb-shaped rotor to achieve the dehumidification function.

[0003] However, traditional rotary dehumidifiers are significantly affected by both low and high temperature environments. The working principle of a rotary dehumidifier is to adsorb and dehumidify the air by using adsorption materials. However, the adsorption capacity of these materials decreases significantly in low-temperature environments, resulting in poor dehumidification effects or even failure to function properly. Furthermore, the warm air in the regeneration section of a rotary dehumidifier needs to be heated, which consumes a lot of electricity. After using the heater, the room temperature will rise by 2-3°C. Therefore, it is not advisable to use it frequently during the hot summer months.

[0004] Therefore, how to make rotary dehumidifiers better adapt to changing ambient temperatures has become an urgent problem to be solved. Utility Model Content

[0025] Traditional rotary dehumidifiers are significantly affected by both low and high temperature environments. The working principle of a rotary dehumidifier is to adsorb and dehumidify the air by adsorbing moisture from the air using adsorption materials. However, the adsorption capacity of these materials decreases significantly in low-temperature environments, resulting in poor dehumidification effects or even failure to function properly. Furthermore, the warm air in the regeneration section of a rotary dehumidifier needs to be heated, which consumes a lot of electricity. Using a heater will raise the room temperature by 2-3°C, so it is not advisable to use it frequently during the hot summer months.

[0026] Therefore, how to make rotary dehumidifiers better adapt to changing ambient temperatures has become an urgent problem to be solved.

[0027] The design concept of this application is to utilize the heat of the rotary dehumidifier itself to adapt to low-temperature conditions. At high temperatures, the intake evaporator and regeneration evaporator absorb the heat from the incoming fresh air and the exhaust regeneration air for regeneration air heating. This not only reduces energy consumption but also reduces the heat of the incoming fresh air and the exhaust regeneration air, preventing the ambient temperature from rising. At low temperatures, the intake condenser connected to the compressor pump preheats the incoming fresh air, reducing the heat exchange temperature difference of the rotor and ensuring that the rotor can operate normally as much as possible.

[0028] like Figure 1 As shown, this application provides a total heat recovery dehumidification rotary fresh air device, including a fresh air duct 1, a rotary wheel 2, a fresh air fan 3, a regeneration air duct 4, and a regeneration fan 5; the fresh air duct 1 includes an air inlet duct 101, the regeneration air duct 4 includes a regeneration air inlet duct 401 and a regeneration air outlet duct 402, a compressor pump 6 and a regeneration condenser 7 connected to the compressor pump 6 are provided on the regeneration air inlet duct 401, an air inlet preheating duct 8 and an air inlet heat absorption duct 10 are provided on the front side of the air inlet duct 101, an air inlet condenser 9 is provided on the air inlet preheating duct 8, and an air inlet evaporator 11 is provided on the air inlet heat absorption duct 10; a regeneration evaporator 12 is provided on the regeneration air outlet duct 402; the air inlet condenser 9, the air inlet evaporator 11, and the regeneration evaporator 12 are respectively connected to the compressor pump 6.

[0029] The air inlet preheating channel 8 and the air inlet heat absorption channel 10 are connected by a T-type three-way valve 13, which is connected to the air inlet channel 101. In this application, the air inlet is divided into preheating and heat absorption. The T-type three-way valve 13 is used to switch the air inlet heat absorption channel 10 and the air inlet channel 101 on and off, and to switch the air inlet preheating channel 8 and the air inlet channel 101 on and off.

[0030] The air inlet evaporator 11 and the regenerator evaporator 12 are connected by a confluence tee 14, which is connected to a confluence pipe 15, which is connected to the input end of the compressor pump 6; and a confluence valve 16 is provided between the confluence tee 14 and the compressor pump 6.

[0031] The output end of the compressor pump 6 is connected to a diversion pipe 17, the diversion pipe 17 is connected to a diversion tee 18, one end of the diversion tee 18 is connected to the regeneration condenser 7, and the other end of the diversion tee 18 is connected to the air inlet condenser 9; a diversion valve 19 is provided between the other end of the diversion tee 18 and the air inlet condenser 9.

[0032] In this application, the air inlet is divided into preheating and heat absorption sections. At high temperatures, the air inlet heat absorption channel 10 is connected to the air inlet channel 101. Fresh air that has absorbed heat through the air inlet evaporator 11 enters the air inlet channel 101. The confluence valve 16 is open, and the heat absorbed by the air inlet evaporator 11 and the regeneration evaporator 12, along with the heat generated by the compressor pump 6, are transferred to the regeneration condenser 7 to heat the regeneration air inlet, reducing energy consumption and lowering the temperature of the fresh air inlet and regeneration air exhaust. At low temperatures, the air inlet preheating channel 8 is connected to the air inlet channel 101. Fresh air that has been preheated by the air inlet condenser 9 enters the air inlet channel 101. The diversion valve 19 is open, and the heat generated by the compressor pump 6 is used not only for the regeneration condenser 7 to heat the regeneration air inlet but also for the air inlet condenser 9 to preheat the fresh air inlet, reducing the heat exchange temperature difference of the impeller and ensuring normal operation of the impeller.

[0033] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
