Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air treatment, in particular to a humidification fresh air handling unit. BACKGROUND

[0002] The humidification fresh air handling unit is an advanced air treatment equipment. In use, the solution absorbs or releases moisture from the air to achieve precise adjustment of the air humidity. For example, in a humid environment, the solution can absorb excess moisture in the air to achieve dehumidification. In a dry environment, the solution can release moisture to the air for humidification. The humidification fresh air handling unit usually includes a cold heat source, a total heat recovery section (for some models), an air humidification and dehumidification treatment section, a filtration section, and a fan section, etc. This means that it can independently complete a series of processes such as cooling, heating, dehumidification, humidification, and purification of the air without additional auxiliary equipment, greatly simplifying the complexity of the system. In different seasons, there are different operating modes. In summer, the outdoor fresh air is first pre-processed (such as cooling and dehumidification), and then enters the solution humidification unit for further processing to the appropriate supply air state point. In winter, the four-way valve is switched to change the direction of the refrigerant circulation to achieve air heating and humidification.

[0003] A high-efficiency temperature and humidity control fresh air handling unit is disclosed in Chinese patent document CN223077083U. The fresh air handling unit includes a fresh air channel and a return air channel located in the casing. The fresh air channel is provided with a filter screen, a fluorine pump system, an evaporator, a reheating coil, a humidifier, and a supply fan. The return air channel is provided with a filter screen, a fluorine pump system, a condenser, a compressor, a supply fan, and a fluorine pump system located between the filter screen and the evaporator. The fluorine pump system includes a sprayer, a heat exchanger, a copper pipe, and a pump. The reheating coil is connected with a one-way valve and an electromagnetic valve. The evaporator is also connected with an expansion valve.

[0004] In use, air enters the casing through the fresh air inlet and then passes through the filter screen and the fluorine pump system. The fluorine pump system can first perform preliminary cooling on the fresh air when processing the fresh air, thereby reducing the refrigerating capacity of the compressor and reducing energy consumption. The fluorine pump system contains a water spray. When the water pump is turned on, the refrigerant in the copper pipe is cooled and liquefied, and then pumped into the upper part for recycling. The evaporator evaporates and condenses to release heat. Part of the released heat is returned to the reheating coil to further warm the supply air. The humidifier cools the reheating coil, and then the supply fan sends the air out through the air outlet. In the return air channel, air enters the casing through the return air inlet and then passes through the filter screen, the fluorine pump system, and the condenser before being discharged from the air outlet of the exhaust air outlet.

[0005] However, the above patent documents still have the following deficiencies: when used in winter when there is more dust outside and the dust humidity is high, for example, when used near a building construction site in winter in humid weather, the high humidity dust is easy to adhere to the filter screen, causing the filter screen to be blocked, in order to avoid affecting the ventilation effect of the device, the filter screen needs to be cleaned frequently.

[0052] Working principle:

[0053] When used in the environment with much dust and humid air in winter, the fan 17 is started to generate air flow to deliver the outdoor fresh air into the fresh air channel 13 through the air inlet pipe 15. At this time, the filter 34 filters the fresh air entering the fresh air channel 13 to make the humid dust adhere to the filter 34. The filtered fresh air enters the air guide cavity 313 and is discharged through the opening 1 at the top of the partition 312 to make the fresh air continue to flow towards the air inlet face 22 of the heat exchange core 21. Then the fresh air enters the heat exchange core 21 from the air inlet face 22 and is discharged from the air outlet face 24. Then the fresh air is delivered into the humidity adjusting mechanism through the air outlet pipe 16 to be adjusted in humidity. After the humidity adjustment, the fresh air is delivered into the room.

[0054] The fan 110 is started to generate air flow to make the indoor air enter the air outlet channel 14 through the air return pipe 18. Then the indoor air in the air outlet channel 14 enters the heat exchange core 21 from the air inlet face 23 and is discharged from the air outlet face 25. The temperature of the indoor air is higher than that of the outdoor fresh air to make the indoor air and the outdoor fresh air exchange heat when passing through the heat exchange mechanism 2.

[0055] The driving member 33 is started to drive the filter 34 to operate. The part of the filter 34 with humid dust adhered gradually enters the partition cavity 314 and is blocked by the blocking member 35 at both ends of the partition cavity 314.

[0056] When the filter 34 operates, the connecting belt 341 is engaged with the gear 352 to drive the rotating part 351 to rotate. When the rotating part 351 rotates, it drives the ten blocking parts 353 to ensure that the three blocking members 35 can block the two ends of the partition cavity 314 and the end of the partition cavity 324 away from the partition plate 12, respectively.

[0057] After the part of the filter 34 with humid dust adhered enters the air outlet channel 14, the indoor air passing through the heat exchange core 21 blows to the part of the filter 34 with humid dust adhered to dry the humid dust. Then the indoor air passing through the filter 34 enters the air guide cavity 323 and is discharged through the opening 2 at the top of the partition 322. Then the indoor air is discharged outward through the air outlet pipe 19.

[0058] After the filter 34 drives the dried dust to enter the partition cavity 324, the partition cavity 324 and the blocking member 35 inside the partition cavity 324 are used to partition.

[0059] The filter 34 drives the connecting belt 341 to engage and drive the gear two 362, so that the gear two 362 drives the rotating part two 361 to rotate, and the rotating part two 361 drives the pushing part 363 to move along a circular track, when the pushing part 363 passes the knocking part 365, the knocking part 365 is pushed to move away from the filter 34 under the guidance of the guide rail 364, and the elastic part 366 is compressed, after the pushing part 363 separates from the knocking part 365, the knocking part 365 is reset by the elastic part 366 and knocks the filter 34, so that the dried dust is separated from the filter 34, and the dried dust separated from the filter 34 falls into the collecting part 37 for collection.
