[0002] The fresh air chambers of HVAC are mainly applied to the industrial environment of electronic factories with large fresh air volume requirements, especially in places where the external environment pollution of the factory building is relatively serious, the primary fresh air filter fails quickly, and the space of the machine room is limited.

[0003] In the prior art, there are generally two types of fresh air chambers: one is a fresh air chamber with a width of 1-2 meters separated near the louver. The air inlet of the fresh air unit is connected to the fresh air chamber through a fresh air pipe, and the air is taken from the fresh air chamber. A rain and insect-proof fresh air louver is arranged on the outer wall side, or a primary filter section is further configured; the other is that the entire fresh air machine room is used as a fresh air chamber, and the fresh air unit directly takes air from the machine room, and an automatic filter box is arranged at the fresh air inlet.

[0004] The problem of the first structure is that it is necessary to configure special operators to replace the filter media of the filter, and the operation and maintenance cost is relatively high. The problem of the second structure is that there is a problem of large dust when taking air directly, the air intake quality is poor, and it occupies the space of the machine room, affecting the maintenance and repair work. Content of the Utility Model

[0005] The fresh air chamber proposed by the utility model aims to overcome the above-mentioned deficiencies existing in the prior art, realizing no need to replace the filter media, not affecting the maintenance and repair of the machine room, and ensuring the air intake quality.

[0006] The technical solution of the utility model: A fresh air chamber, whose structure is separated by color steel plates in the MAU machine room. There are multiple MAUs in the MAU machine room. The air outlets of the MAUs are connected to fresh air ducts. The color steel plates are arranged along the outer sides of all MAUs and overlap on the MAUs, and are connected to the ground of the MAU machine room. A fresh air chamber is formed between the outer side of the color steel plate, the outer side of the MAU and the outer wall of the MAU machine room. The pipeline valves of the MAU are located outside the fresh air chamber. The formed independent space fresh air chamber does not affect the normal maintenance and repair of the MAU machine room and can avoid the pipeline from being frozen.

[0007] Preferably, an air intake filtering mechanism is arranged at the air inlet of the outer wall. The air intake filtering mechanism includes a wind-proof louver installed outside the air inlet and an automatic winding air filter installed inside the air inlet. An insect-proof net is arranged between the wind-proof louver and the automatic winding air filter. It can initially filter the incoming fresh air. The filter can automatically replace the filter media, without the need to configure special operators, and can save the operation and maintenance cost.

[0008] Preferably, a reserved frame opening is provided on the outer side of the MAU. The bottom of the color steel plate is inserted into the reserved frame opening through the socket groove aluminum. An aluminum alloy inner arc skirting board is provided at the corner between the top of the MAU and the color steel plate, and neutral silicone sealant is filled inside the aluminum alloy inner arc skirting board.

[0009] Advantages of the present utility model: 1) An automatic winding air filter is preferably used at the fresh air intake, eliminating the need for dedicated operators. The filter can automatically replace the filter media, saving operation and maintenance costs.

[0010] 2) The fresh air intake filtering mechanism is arranged on the side of the fresh air louver, which can not only ensure the quality requirements of the fresh air intake for the fresh air unit but also avoid the problem of large dust intake directly from the air conditioning machine room.

[0011] 3) The fresh air chamber is reasonably structured, separating the operation area and the intake area of the machine room. The water pipe interfaces are not exposed in the fresh air area, reducing the risk of freezing of the water pipes, ensuring the maintenance space above the machine room, and preventing rain, snow, and dust from entering the air conditioning machine room along with the fresh air during rainy and snowy weather, ensuring the cleanliness inside the air conditioning machine room and reducing the cleaning and maintenance costs of the machine room.
