Embodiment Construction

[0049] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0050] In this embodiment, the device includes an upper box body 1, a lower box body 2, and an air chamber 3. A fresh air inlet 4 is opened on the back cavity wall of the upper chamber of the upper box body 1 to allow the outside air to enter. The air volume regulating valve 13 is set at the air outlet 4, and a protective cover 15 is equipped in front of the fresh air inlet 4. The interlayer 20 between the inner wall 21 and the outer wall 19 of the protective cover 15 is filled with sound-absorbing materials. The protective cover 15 contains an anti-bird net 22, and the upper box The upper part of the body 1 is provided with a return air system 14, the middle part of the upper box body 1 is provided with an initial effect filter 5, the lower part of the upper box body 1 is provided with a heat exchanger 6 for heating air, and the water inlet pipe 11 and the re...

Abstract

The invention discloses a wall type fresh air conditioning unit. The wall type fresh air conditioning unit comprises an upper box body, a lower box body and an air chamber arranged in sequence from top to bottom and communicating with each other; a primary filter for dividing the upper box body into an upper cavity and a lower cavity is arranged at the middle part of the upper box body; two heat exchangers are arranged at the bottom of the lower cavity side by side; two axial flow fans are arranged at the middle part of the lower box body side by side; and the two axial flow fans are arrangedcorresponding to the heat exchangers above the axial flow fans. The wall type fresh air conditioning unit can improve the airflow structure, improves the efficiency, and further reduces the noise, hasdifferent-type hole plate process selections, facilitates maintenance of the paper mill indoor humidity within a standard range, prevents the influence on the production efficiency and the product quality by lower humidity, is more uniform and stable in air supply currents, and is more uniform and sufficient in heat exchange degree.

Description

technical field [0001] The invention belongs to the field of air conditioning devices, and relates to wall-type fresh air treatment units of different models and specifications, which are used in tall and large spaces for papermaking, textile and other industrial process applications, and meet the process requirements of ventilation, cooling and heating. Background technique [0002] In the workshop environment such as paper mills, the air circulation is not smooth, and the heat generated by the machine needs to be treated. At the same time, the steam, smoke, dust and other harmful substances that may be generated during the machine work in the workshop need to be exhausted to remove, and fresh air must be replenished in time. Therefore, paper mills usually use axial flow fans to ventilate the workshop. However, this fan must be equipped with a machine room, which not only occupies the usable area of ​​the workshop, increases the cost of use, but also generates a lot of noise...
