Description

Wind wall type indoor AHU

Technical Field

The utility model relates to an indoor AHU especially relates to an indoor AHU of headwall formula.

Background

AHU is an english abbreviation of Air handling unit (Air handling unit). The indoor air and part of outdoor fresh air are directly mixed and processed by the equipment for adjusting the temperature, humidity and cleanliness of the indoor air and then are sent to the indoor for temperature adjustment. However, the existing AHU has large energy consumption, low air supply efficiency and increased cost.

SUMMERY OF THE UTILITY MODEL

The application provides an indoor type AHU of headwall formula realizes the cooling of dust free chamber, in order to realize above-mentioned purpose, adopts following technical scheme: the method comprises the following steps: the surface air cooler is arranged between the fan and the filter, and the filter is positioned at an air supply outlet of the dust-free chamber.

Preferably, the air inlet of the fan is further provided with a coarse filter layer.

Preferably, a wet film is further arranged at the air inlet of the fan and is positioned between the coarse filter layer and the fan.

Preferably, the fans are arranged in a plurality of rows at equal intervals, and each row is provided with a plurality of blowers.

Preferably, the surface cooler adopts a fan coil surface cooler, and is connected with the hydraulic module through a pipeline.

Preferably, the filter is a high-efficiency filter without a partition plate.

The utility model has the advantages that: the air cooler consists of a filter, a surface cooler and a fan, the heat exchange area is large, the air supply speed and dynamic pressure are reduced, the static pressure is increased, the air supply kinetic energy loss is reduced, the cold air is further and more uniform, the standardized production can be realized, the speed is high, the quality is high, the cost is low, and the project period is saved.

In the figure, 1, a fan; 2. a surface cooler; 3. a filter; 4. a box body; 5. a coarse filter layer; 6. and (5) wet film forming.

Detailed Description

As shown in fig. 1, the present invention includes: the box, box inside is provided with fan, surface cooler and filter, the surface cooler sets up between fan and filter, the filter is located the supply-air outlet play of dust free chamber.

Preferably, the air inlet of the fan is further provided with a coarse filter layer, so that preliminary coarse filtering of external air inlet is realized.

Preferably, the air inlet of the fan is further provided with a wet film, and the wet film is located between the coarse filter layer and the fan and used for primarily cooling the external air.

Preferably, the fans are arranged in a plurality of rows at equal intervals, and each row is provided with a plurality of air blowers for conveying the air subjected to preliminary coarse filtration and preliminary cooling to the dust-free chamber.

Preferably, the surface cooler adopts a fan coil surface cooler, the surface cooler is connected with the hydraulic module through a pipeline, and the fan carries out further water-cooling on the air after primary coarse filtration and primary cooling to the process of conveying the air to the dust-free chamber.

Preferably, the filter adopts no baffle high efficiency filter, carries out the high efficiency filtration with cold wind after to the dust free chamber to realize the effect of cooling.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
