Embodiment 1

[0056] For large-space offices or data center computer rooms, the existing technology often adopts top mixed air supply or floor air supply, which has problems such as low ventilation efficiency and unsatisfactory air quality of the air supply. In this embodiment, the air supply device is arranged in the middle of the room. The group can adopt combined air conditioning unit or fresh air unit, etc., such as Figure 4 and 5 As shown, the pre-embedded air duct 10 is connected to it and arranged in the interlayer of the floor. The air supply air flow passes through the filter unit and hits the mushroom-shaped baffle and is sent out from the annular air outlet 2. The wall surface of the attached cylinder 6 flows downward to the ground, along the The ground spreads to the whole room, forming an air lake.

[0057] Such as Figure 8 As shown in (a1), the structural parameters of the room are 20m×20m×3m (length×width×height), the radius of the cylinder 6 is 0.5m, the width of the ann...

Embodiment 2

[0059] For office space, such as Figure 9 As shown in (a1), its structural parameters are 10m×10m×3m, and the ventilation column is arranged in the middle of the room. Under the cooling condition in summer, the indoor design temperature is 26°C, the heat source is evenly arranged on the side wall of 25.7W / ㎡, and the air supply speed is 2m / s, the air supply temperature is 18°C, the return air outlet is arranged in the upper part of the room, the radius of the cylinder 6 is 0.5m, the width of the annular air outlet 2 is 0.05m, and the size of the four return air outlets is 0.4m×0.4m, arranged in the room top.

Abstract

The invention belongs to the technical field of ventilating air conditioners, and relates to a wall-attached air supply device integrated with an air purification system. The wall-attached air supply device integrated with the air purification system comprises a column body, a pre-buried air pipe, a mushroom head baffle, an air outlet plate and an annular air guide plate, wherein the upper end of the column body is connected with the air outlet plate; the mushroom head baffle is arranged on the air outlet plate in a covering mode; a circular air outlet is formed in the center of the air outlet plate; an annular air outlet is formed in the outer edge of the air outlet plate; the annular air guide plate is placed between the circular air outlet and the annular air outlet; and a pre-filter screen, an activated carbon filter and a medium efficiency filter are sequentially arranged in the column body from bottom to top. The invention further discloses an air supply method of the wall-attached air supply device integrated with the air purification system. The advantages of an air supply system and attached jet flow are combined, air supply airflow is attached downwards along a column wall and enters a working area after impacting a floor, and air lake airflow distribution is formed on the ground, namely, low-air-speed and small-temperature-difference airflow is evenly diffused along the ground, so that the air supply efficiency is improved; and by arranging a filtering system, the problem that the indoor air quality is reduced due to the fact that dust in a floor interlayer flows along with the air supply airflow can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of ventilation and air conditioning, and in particular relates to a wall-mounted air supply device for an integrated air purification system and an air supply method thereof. Background technique [0002] The main forms of air distribution in indoor spaces are mixed ventilation and displacement ventilation: [0003] Mixed ventilation uses mechanical force as the source power to drive the mixing of delivery air and indoor air to achieve the design parameters. The mechanical force is generally "opposite" to the buoyancy force of the indoor thermal plume—the supply air is strongly mixed with the indoor air, basically there is no thermal stratification, and the temperature and humidity are evenly distributed throughout the space. However, mixing ventilation aims to eliminate all indoor loads, and the ventilation efficiency is low; while displacement ventilation replaces indoor polluted air from bottom to top, t...
