Description

Technical Field

[0001] This invention belongs to the field of air conditioning equipment technology, and particularly relates to a multifunctional adaptive air conditioning air distributor. Background Technology

[0002] The protection of people inside motor vehicles is mostly done through collective protection. However, for some special vehicles, which have poor airtightness, it is difficult to achieve collective protection. In such cases, individual protection is generally used, such as filter-type gas mask protection, personal air respirator protection, or personal oxygen respirator protection.

[0003] Filter-type gas masks mainly consist of a mask and a filter canister, using negative pressure filtration and adsorption purification. The mask isolates the face and respiratory organs from the outside environment, while the filter canister purifies polluted air. Clean air is inhaled for protection. However, they suffer from high inhalation resistance, causing discomfort such as suffocation. Furthermore, in emergencies, panic can lead to improper mask fitting, leaks, and the entry of toxic gases, posing a life-threatening risk. Personal air respirators (BAS), on the other hand, mainly consist of a mask, air tube, pressure reducing valve, and compressed air cylinder, providing positive pressure clean air. They do not cause suffocation, but because the air is supplied by a compressed air cylinder, their protection time is shorter, and they are larger and heavier. Personal oxygen respirators mainly consist of a mask, air tube, pressure reducing valve, and compressed oxygen cylinder, providing positive pressure oxygen supply protection. Their principle is the same as that of personal air respirators, except that the supplied air is replaced with oxygen. Therefore, they can provide protection for a longer period of time than air cylinders of the same pressure and volume. Their advantages and disadvantages are the same as those of personal air respirators, but attention should be paid to explosion and fire prevention to avoid greater secondary hazards such as fires and explosions.
