Arc-shaped column position wall-attached jet air supply device in combination with fan coil

Abstract

The invention discloses an arc-shaped column position wall-attached jet air supply device in combination with a fan coil. The air supply device comprises the fan coil, an air hose and an arc-shaped plenum chamber; the arc-shaped plenum chamber is disposed on the upper portion of an arc-shaped column of a building; an arc-shaped adjustable slot air outlet comprises a translation adjustment device and a rotary adjustment device; the translation adjustment device is mounted at the bottom of a shell of the arc-shaped plenum chamber and can perform translation sliding along the surface of the bottom of the shell; the rotary adjustment device is connected to one end of the translation adjustment device and can rotate around the connecting end; the air speed and direction of the arc-shaped adjustable slot air outlet can be controlled through translation of the translation adjustment device and / or rotation of the rotary adjustment device, so that wall-attached jet air supply is achieved. The air supply device can achieve air direction and air speed adjustment within the range from 0 degree to180 degrees and change of multiple wall-attached jet air supply modes through the innovative designof the air supply outlet structure and cooperation of the interior of the air supply device, the application scenario is wide, the self-adaptability is high, and the economic cost is low.

Description

technical field [0001] The invention belongs to the technical field of ventilation and air conditioning, and in particular relates to a jet air supply device attached to an arc-shaped column combined with a fan coil unit. Background technique [0002] In indoor ventilation technology, the traditional hybrid ventilation mode is characterized by high speed, high momentum and turbulent air supply. It is still widely used because it is easy to arrange in the building space and does not occupy the lower building space (working area). However, it entrains a large amount of indoor air during the air supply process, and the work area is generally in a return air or exhaust environment, and the ventilation efficiency and sanitary conditions are relatively poor. [0003] In view of this, the inventor of the present application has proposed a kind of air supply method (such as Figure 8 As shown), by installing the air outlet and the annular plenum box of the air outlet on the top of t...

Problems solved by technology

[0005] 1. In this air supply method, a large number of various types of air ducts need to be arranged on the top of the room, and each air duct needs to be equipped with a corresponding adjustment valve. The system is complex, noisy, cumbersome to control, and takes up a lot of space;

[0006] 2. The air outlet is an annular slit air outlet surrounding the cylinder, the overall shape is fixed, and the air outlet only has a state and mode of vertical downward, which cannot realize self-regulation of wind speed and direction;

[0007] 3. In the comparison test of Example 1 / 3, it is necessary to separately set the air supply valve or adjust the power gear of the fan to adjust the wind speed of the air outlet of the annular slit; in the comparison test of Example 1 / 2, it is necessary to design two sets of different sizes. A static pressure box is used to adjust the distance between the annular slit air outlet and the cylindrical surface, which is not conducive to industrial manufacturing, high cost and poor adaptability;

[0008] 4. It can only be used for the case where the cylinder is vertically attached to the wall. The mode is unique. Due to the different actual working conditions such as the size of the room space, the location of the cylinder, and the distance from the air supply target area or the target crowd, only the column is vertically attached to the wall and The single mode that cannot be adjusted can no longer be applied to complex scenes. For example, when the room is larger, or when the cylinder is far away from the air supply target area or target group, the air supply effect is too poor, or the cylinder adopts hidden settings and cannot be arranged vertically against the wall.
