Technical Field

[0001] This utility model relates to the field of air purification equipment technology, specifically a dehumidifying bidirectional flow total heat exchange fresh air unit. Background Technology

[0002] The dehumidifying bidirectional flow total heat exchange fresh air system is an air handling device that integrates multiple functions such as dehumidification, fresh air introduction, heat exchange, and air purification. With its high efficiency, energy saving, comfort, and intelligent features, the dehumidifying bidirectional flow total heat exchange fresh air system has broad application prospects in modern homes and buildings. Especially in places with high indoor environmental requirements, such as high-end residences, office buildings, and hospitals, this type of fresh air system will become an important choice for improving indoor air quality and enhancing the quality of life.

[0003] The existing technology still has the following drawbacks in its use: The air purification effect of existing fresh air systems still needs improvement, and they cannot effectively control the increase or decrease of indoor humidity, thus failing to ensure a comfortable and healthy living environment. They are also not well adapted to different air conditions in different seasons, and they cannot achieve good energy saving.

[0004] In view of this, we propose a dehumidifying bidirectional flow total heat exchange fresh air unit to solve the existing problems. Summary of the Invention

[0008] Preferably, a graphene total heat exchange chip is installed inside the housing, a fresh air electric valve is installed at the lower end of the graphene total heat exchange chip, and a dehumidifier is installed at the lower end of the fresh air electric valve.

[0009] Preferably, an exhaust fan and an internal circulation electric air valve are respectively installed inside the shell on the side of the graphene total heat exchange core.

[0010] Preferably, an air filter element is provided inside the housing near the fixed-frequency fan, and an air filter assembly is connected to the rear end of the air filter element.

[0011] Preferably, a door latch is provided at the side connection of the housing, a lifting hook and a rubber shock-absorbing washer are installed on the outside of the housing, and an electrical box is installed between the multiple sets of air vents.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes a multi-mode air handling unit, a bidirectional flow fresh air purification, sterilization, dehumidification, and humidification integrated machine. Its main functions are indoor air replacement and humidity control. Fresh outdoor air is filtered, dehumidified, and sterilized. The internal circulation vents independently ensure the cleanliness of the passage. The centralized return air and fresh air form a total heat recovery, and then 18kW of cooling capacity is used for surface cooling and humidification to achieve the required healthy environment. Simultaneously, the polluted indoor air is discharged through independent air ducts, forming a repeated airflow replacement, which provides a healthy replacement of indoor air while controlling cleanliness, humidity, environmental noise, and energy saving.

Detailed Implementation

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a dehumidifying bidirectional flow total heat exchange fresh air unit, including a fresh air total heat exchange mode: The air supply can be either floor-mounted or ceiling-mounted, allowing for diverse installation options. Fresh outdoor air is drawn into the outdoor fresh air inlet 6, then opened by the fresh air electric valve 16 and closed by the internal circulation electric valve 20. After being filtered by the air filter assembly 13, the air enters the static pressure zone by the fan and is then delivered to the dehumidifier 18 under positive pressure, where the moisture in the air is condensed and dehumidified. After passing through the wet membrane assembly, the condensate is discharged outdoors by the water collection tray, and the dry air is delivered indoors through the indoor air outlet 7. The indoor return air outlet 8 draws in the concentrated return polluted air, which is then discharged by the fixed frequency fan 11 through the silenced independent air duct.

[0017] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a dehumidifying bidirectional flow total heat exchange fresh air unit, including an internal circulation mode: When the fresh air electric damper 16 is closed, the internal circulation electric damper 20 is activated, the variable frequency air supply fan is started, the outdoor exhaust variable frequency fan 19 stops operating, the outdoor check valve automatically closes by gravity, and the indoor return air passes through the air filter, then through the internal circulation electric damper 20 and the dehumidifier 18 to achieve the purpose of indoor circulation and dehumidification. Internal circulation is generally used during the rainy season to achieve effective and rapid dehumidification.

[0018] Example 3: Figure 1 , Figure 2 and Figure 3 As shown, this utility model proposes a dehumidifying bidirectional flow total heat exchange fresh air system, including a total heat exchange constant oxygen mode: The internal circulation electric air valve 20 and the fresh air electric air valve 16 open proportionally, achieving both internal circulation and the proportional mixing of external fresh air before it is drawn into the surface cooling coil, thus maintaining constant oxygen levels and meeting various indoor air health needs. In some cities where winters are relatively dry, the surface cooling coil operates in heating mode, and the terminal humidifier increases air humidity, preventing dry mouth and throat, and achieving a comfortable environment with a balance between humidity and temperature in winter. The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the related teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
