Cyclic redundancy ventilation system and application

Abstract

The invention belongs to the technical field of air conditioning, and discloses a cyclic redundancy ventilation system and application. The cyclic redundancy ventilation system comprises an air conditioning unit, an air supply duct in butt joint with an air supply outlet of the air conditioning unit, an air return duct in butt joint with an air return port of the air conditioning unit, an air supply and guide pipe in butt joint with the opening of the air supply duct, a return air guide pipe in butt joint with the opening of the return air duct, and a mounting bracket used for mounting and fixing. The system is mainly applied to circulating ventilation in various operation shelters or compartments and redundant backup ventilation under special conditions.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a circulating redundant ventilation system and its application. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] In the traditional work shelter or box, it is generally equipped with a top-mounted air-conditioning unit, and its air supply and return air are at the top of the head. In larger shelters, install two or more air conditioning units. During use, the following problems often occur: [0004] When personnel are working in shelters or compartments, air from the air conditioner is often blown directly to the top of the head, causing discomfort to the personnel; the air supply and return air outlets of th...

AI Technical Summary

Problems solved by technology

[0004] When personnel are working in shelters or compartments, the air from the air conditioner is often blown directly to the top of the head, causing discomfort to the personnel; the air supply and return air outlets of the air conditioner are concentrated in one or two places, which is prone to "cross wind" and "wind". "Short circuit" and other problems, resulting in poor cooling effect in the cabin, uneven heating and cooling in the space, and people feel uncomfortable; when the air conditioner in a large shelter or a certain space in the box fails to work normally due to accidents, there is no redundant backup way; when the air is directly supplied by the roof-mounted air conditioning unit, it often does not pass through the air duct, and the noise of the internal circulation fan will be directly transmitted into the shelter or box
