Slit nozzles for air conditioning ventilation systems

Abstract

The invention discloses a slit nozzle of a ventilation system of an air conditioner. According to the slit nozzle of the ventilation system of the air conditioner, an upper piece (2) is arranged on the upper surface of the slit nozzle and a lower piece (3) is arranged on the lower surface of the slit nozzle, the left side of the slit nozzle and the right side of the slit nozzle are respectively provided with a flat plate, and then a shell body with four sides sealed is formed; the upper piece (2) and the lower piece (3) are of arc-shaped curved surface structures and a space necking gradually from back to front is formed inside the slit nozzle; shutters (4) are arranged inside the front end of the slit nozzle, a front panel A (5) is arranged above the front end of the slit nozzle, and a front panel B (6) is arranged below the front end of the slit nozzle; tail connecting tubes (1) are arranged on the rear portion of the slit nozzle. The slit nozzle of the ventilation system of the air conditioner has the advantages that requirements of the current market are met, and the air output provided by the slit nozzle can reach 4-6 times of that provided by a traditional spherical nozzle under the condition that the height of the decoration external dimension is not changed; due to the fact that the height of the slit nozzle is small, the air output is large, the air supplying range is wide, the direction of air can be adjusted, and the distance of air supplying can generally reach more than 30m.

Description

technical field [0001] The invention relates to an air-conditioning and ventilation system, in particular to a spout of terminal equipment of the air-conditioning and ventilation system. Background technique [0002] At present, in the industry field of air-conditioning and ventilation systems, spherical nozzles are widely used, and their appearance is circular. Its typical structure is to process a circular tapering nozzle in a spherical metal body. The section curve of the circular contracting surface inside the nozzle is an arc to reduce air flow resistance and noise. The metal sphere is embedded in a circular decorative panel. Usually, a connecting sleeve is installed on the back of the decorative panel to wrap the main metal sphere, which is also convenient to connect with the ventilation duct; its structure is as follows: figure 1 shown. [0003] This spherical nozzle achieves two functions: 1. The internal tapered nozzle can increase the jet flow velocity, so that t...

Problems solved by technology

In addition, for some large buildings, when the air supply volume is large, the diameter of the nozzle selection is large, which is not easy to install, and it is also inconvenient to cooperate with the decoration design.
