[0002] In the storage or operation spaces of some factories, in order to ensure the stable performance of equipment or products, such spaces usually have special requirements for temperature and humidity, so a rotary dehumidifier needs to be used to control the environmental temperature and humidity.

[0003] A rotary dehumidifier is a device that uses a rotary wheel made of a moisture-absorbing material to adsorb moisture in the air, and then removes the moisture on the rotary wheel through an electric heating and exhaust system, thereby achieving the purpose of dehumidification.

[0004] The existing rotary dehumidifiers remove the moisture on the rotary wheel by generating hot air for drying through electric heating. However, simply using the electric heating method to dry the rotary wheel will lead to technical defects of poor dehumidification effect and high energy consumption. On the other hand, if only the power of the electric heating structure is increased, the temperature in the dehumidification environment will rise, seriously affecting the dehumidification effect.

[0023] Further, after the pre-cooled air passes through the rotating runner so that the moisture in the air is adsorbed by the runner to obtain dried air, the method further includes the step of:

[0024] S31. The dried air flow passes through the second filter to obtain clean and dry air, and the air is discharged into the room.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present.

[0059] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0060] The embodiment of the present invention provides a rotary dehumidifier 100.

[0061] Please refer to Figure 1 , a rotary dehumidifier 100, comprising:

[0062] A rotating wheel 110, which is used for rotating and absorbing moisture;

[0063] An auxiliary heater 120, which is used to provide an auxiliary heat source;

[0064] The regeneration air duct 130 is provided with a fan 131 inside. The auxiliary heater 120, the runner 110, and the fan 131 are arranged in sequence in the regeneration air duct 130. The fan 131 is used to absorb the heat of the electric heating device to dry the runner 110 and discharge the air carrying moisture to the outside; and,

[0065] A heat pump system 140, the heat pump system 140 includes a compressor 141, and an evaporator 142 and a radiator 143 both arranged in the regeneration air duct 130; the evaporator 142 is arranged between the fan 131 and the runner 110, and the evaporator 142 is used to make the heat exchange medium absorb heat and recover the heat of the auxiliary heater 120. The compressor 141 is respectively connected to the evaporator 142 and the radiator 143, and is used to drive the heat exchange medium in the evaporator 142 to flow to the radiator 143; the radiator 143 is arranged on the other side of the runner 110 relative to the evaporator 142, and is used to make the heat exchange medium release heat and release heat to the air.

[0066] It can be understood that the technical solution of the present invention enables the device to effectively absorb moisture by setting the runner 110; at the same time, in combination with the auxiliary heater 120 and the heat pump system 140, the drying effect of the runner 110 is improved, thereby enhancing the dehumidification efficiency of the rotary dehumidifier 100. The rotary dehumidifier 100 can increase the contact area with the air by using the runner 110 and in a rotating manner, adsorb the moisture in the air, and thus improve the dehumidification capacity.

[0067] In the technical solution of the present invention, by configuring the heat pump system 140 and arranging the evaporator 142 and the radiator 143 in the ventilation channel, the evaporator 142 recovers the heat released by the auxiliary heater 120 to assist the heat conduction medium in the evaporator 142 to absorb heat and vaporize, reducing the energy consumption of the evaporator 142 and the compressor 141, and increasing the high-temperature heat energy of the radiator 143, thereby reducing energy consumption and lowering the operating cost.

[0068] It can also be understood that in the technical solution of the present invention, the configuration of the fan 131 absorbs the heat of the auxiliary heater 120 and the high-temperature heat of the radiator 143 through the regeneration air duct 130 to dry the runner 110 and discharge the moisture to the outside, ensuring the efficient operation of the runner 110, optimizing the heat distribution in the dehumidification process, and improving the overall thermal efficiency.

[0069] Combined with the specific implementation of this solution, in actual application, the hot air temperature in the regeneration air duct 130 usually needs to be heated to 110°C to 150°C in order to enable the rotary dehumidifier 100 to achieve the best dehumidification effect.

[0070] However, if this part of the heat is only provided by the auxiliary heater 120, it will result in a relatively large energy consumption of the auxiliary heater 120. However, if conventional heat pumps are used for heating, the temperature can only be raised to 50°C to 55°C. The technical personnel of this solution use a special combination of the auxiliary heater 120 and the heat pump system 140 to enable the hot air in the regeneration air duct 130 to reach above 85°C.

[0071] It should also be emphasized that the heat pump system 140 of this technical solution is essentially a high-temperature heat pump system 140. The auxiliary heater 120 in this solution can heat the exhaust air temperature of the regeneration air duct 130 in the rotary dehumidifier 100 to 50°C to 60°C to form regeneration air. The evaporator 142 in this solution can absorb the low-grade heat source of the regeneration air, and then compress it through the work of the compressor 141, so that the radiator 143 can generate a high-grade heat source with a higher temperature, which is used to produce regeneration exhaust air with a higher temperature, achieving energy conservation on the basis of enabling the rotary dehumidifier 100 to achieve a better dehumidification effect.

[0072] It should also be noted that the heat pump system 140 in the technical solution of the present invention further includes devices such as an expansion valve 144, a gas-liquid separator, and heat exchange pipes. The heat transfer and heat conversion of the heat exchange medium in the heat exchange pipes in the heat pump system 140 are common knowledge for those skilled in the art, and those skilled in the art can set it according to the actual needs of the heat pump system 140.

[0073] It can also be understood that the auxiliary heater 120 is an electric heater. The specific setting of the heat pump system 140 in this solution achieves greater energy conservation compared to using only electric heaters to provide high-temperature heat sources.

[0074] Optionally, the auxiliary heater 120 is provided on either side of the radiator 143.

[0075] In a specific embodiment, the auxiliary heater 120 is provided between the runner 110 and the radiator 143. It can be understood that the electric heating device is close to the runner 110, which can ensure that the heat is quickly transferred to the runner 110 when heating the air, reduce heat loss, and improve the heating and drying efficiency. And it is very important that the temperature during the regeneration process of the runner 110 is appropriate. The electric heating device is arranged close to the runner 110, which can more quickly adjust the temperature of the regeneration air to adapt to changing humidity conditions and achieve the best dehumidification performance.

[0076] In a specific embodiment, the air flow direction of the fan 131 is opposite to that of the runner 110.

[0077] It should be noted that this design is mainly to prevent the dehumidified air from being processed again during circulation. The air in the regeneration air duct 130 is usually guided outdoors, while the air in the processing air duct 150 is sent indoors. This design helps to maintain the dryness of the indoor environment and ensure the dehumidification effect.

[0078] Please continue to refer to Figure 1 , in a preferred embodiment of the present invention, the rotary dehumidifier 100 further forms a processing air duct 150, and the processing air duct 150 is sequentially provided with a first filter 161, a water cooling device 170, and the rotary wheel 110; the first filter 161 is used to filter the air to be dehumidified, reduce the impurity pollution in the air to the rotary wheel 110, so as to avoid the decline of the moisture absorption effect of the rotary wheel 110.

[0079] Furthermore, the water cooling device 170 is used for heat absorption and dehumidification, and the rotary wheel 110 is used to provide air power and moisture absorption for the processing air duct 150.

[0080] It can be understood that the setting of the water cooling device 170 is mainly for the pre-treatment of heat absorption and dehumidification. During the operation of the rotary dehumidifier 100, the fresh air is usually in a high-temperature state. If the air is not pre-treated, the high temperature will affect the performance and service life of the rotary dehumidifier 100, and at the same time, the high humidity will also reduce the dehumidification efficiency. Therefore, through the pre-dehumidification effect of the water cooling device 170, the temperature and humidity of the fresh air can be effectively reduced, creating better conditions for the subsequent dehumidification process.

[0081] Specifically, the water cooling device 170 helps to absorb the moisture in the air through chilled water. The water cooling device 170 is arranged in the air inlet direction of the rotary wheel 110. By contacting the humid air before dehumidification, the temperature of the air is lowered, the saturated water vapor content in the air is reduced, and the moisture will be more easily adsorbed onto the rotary wheel 110 and then sent to the regeneration air duct 130 of the rotary wheel 110 for drying treatment.

[0082] Optionally, the water cooling device 170 is composed of a diversion pipe and heat dissipation fins. Specifically, the material of the diversion pipe is copper, and the material of the heat dissipation fins is aluminum or aluminum alloy.

[0083] Optionally, the processing air duct 150 is further provided with a second filter 162, and the second filter 162 is arranged in the exhaust air direction of the rotary wheel 110.

[0084] It can be understood that the first filter 161 is a primary filter, and its main purpose is to reduce the pollution of the rotary wheel 110. The second filter 162 is a medium-efficiency filter or a high-efficiency filter, and the main purpose of the setting of the second filter 162 is to improve the air cleanliness.

[0085] It should also be emphasized that the wheel dehumidifier can be widely used in multiple fields, such as industrial manufacturing, refrigerated storage, indoor air conditioning, etc., and technicians in this field can choose to use filters with different filtering effects according to environmental requirements.

[0086] Optionally, the first filter 161 is a non-woven fabric filter, and the second filter 162 is a pleated filter.

[0087] The present invention also provides a control method of the dehumidifier 100 of the rotary wheel 110, which is applied to the dehumidifier 100 of the rotary wheel 110 described above.

[0088] The control method comprises the steps of:

[0089] S1. Provide an air flow that needs to be dehumidified to obtain clean air filtered by the first filter 161;

[0090] S2, the clean air passes through the water cooling device 170 to obtain pre-cooled air, and the temperature and humidity of the air are reduced;

[0091] S3, the pre-cooled air passes through the rotating wheel 110, so that the moisture in the air is adsorbed by the rotating wheel 110 to obtain dried air;

[0092] S4, providing heat from the auxiliary heater 120 to the heated regeneration air, so that the air temperature rises to 50° C. to 60° C.;

[0093] S5. Provide a heat pump system 140, and set the evaporator 142 and the radiator 143 of the heat pump system 140 in the regeneration air duct 130 to heat the regeneration air to above 85°C; the regeneration air flow heated by the auxiliary heater 120 and the radiator 143 dries the rotor 110, the evaporator 142 absorbs heat so that the heat energy of the rotor 110 is recycled, and the moisture adsorbed by the rotor 110 is taken away and discharged to the outside.

[0094] Furthermore, after the pre-cooled air passes through the rotating wheel 110 so that moisture in the air is adsorbed by the wheel 110 to obtain dried air, the method further includes the following steps:

[0095] S31. The dried air flows through the second filter 162 to obtain clean and dry air, and the air is discharged into the room.

[0096] In one embodiment, a first temperature sensor 181 and a second temperature sensor 182 are disposed in the regeneration air duct 130; the first temperature sensor 181 is disposed on a side of the rotor 110 close to the auxiliary heater 120, and the second temperature sensor 182 is disposed on a side of the evaporator 142 away from the rotor 110;

[0097] The control method further includes the steps:

[0098] S6. The rotary wheel 110 dehumidifier 100 starts to operate, and the first temperature sensor 181 and the second temperature sensor 182 monitor the temperature to obtain the real-time temperature T1 on the side of the first temperature sensor 181 close to the auxiliary heater 120, and the real-time temperature T2 on the side of the second temperature sensor 182 close to the evaporator 142;

[0099] S7. Set the target temperature ranges of T1 and T2 to obtain the temperature ranges of T01 and T02;

[0100] Optionally, T01 ∈ [85°C, 150°C], and T02 ∈ [50°C, 60°C].

[0101] Compare the real-time temperature T1 with the target temperature range T01;

[0102] If T1 < T01min, increase the power of the auxiliary heater 120,

[0103] If T1 > T01max, reduce the power of the auxiliary heater 120 or turn off the auxiliary heater 120;

[0104] Compare the real-time temperature T2 with the target temperature range T02;

[0105] If T2 < T02min, increase the power of the compressor 141 of the heat pump system 140 so that the evaporator 142 absorbs more heat;

[0106] If T2 > T03max, reduce the power of the compressor 141 of the heat pump system 140 or turn off the heat pump system 140;

[0107] S8. Obtain the real-time power data of the auxiliary heater 120 and the heat pump system 140; and perform dynamic adjustment based on the comprehensive energy consumption data.

[0108] Specifically, on the premise of ensuring the drying effect of the rotary wheel 110, the use of the auxiliary heater 120 is preferentially reduced, and the heat pump system 140 is relied on as much as possible for heat recovery and heating. And according to the comprehensive energy consumption data, the operating states of the auxiliary heater 120 and the heat pump system 140 are adjusted in real time to ensure the optimal energy consumption.

[0109] Specifically, continuously monitor the changes of T1 and T2, and according to the feedback information, finely adjust the operating states of the auxiliary heater 120 and the heat pump system 140 in real time to ensure that the temperature is within the target range and achieve the best balance of energy consumption.

[0110] Further, the control method further includes the steps:

[0111] S8. When both T1 and T2 are within the target range and the energy consumption is high, gradually reduce the power of the auxiliary heater 120 and observe the change of T1;

[0112] If T1 drops rapidly, gradually restore the power of the auxiliary heater 120 to the stable state.

[0113] When both T1 and T2 are within the target range and the energy consumption is low, gradually reduce the power of the compressor 141 of the heat pump system 140 and observe the change of T2;

[0114] If T2 drops rapidly, gradually restore the power of the compressor 141 to the stable state.

[0115] Thus, the best optimization of energy consumption is achieved.
