Personal cabin ventilation and lighting

Abstract

A ventilating and lighting apparatus (100) for an individual cabin can improve a contact area between air and a photocatalyst and ensure sufficient light irradiation on the surface of the photocatalyst, and implements rational utilization of an internal space of a cabin by combining with a lighting system. The apparatus (100) comprises an apparatus body housing (110) and an individual lighting assembly (120); a space enclosed by an inner circumferential surface of the apparatus body housing (110) and an outer circumferential surface of the individual lighting assembly (120) constitutes a ventilating flow passage (140); the ventilating flow passage (140) has an air supply inlet (141) and an air supply outlet (142); air from an upstream air inlet component flows from the air supply inlet (141) into the ventilating flow passage (140), and is exhausted from the air supply outlet (142) to an air environment where the individual cabin is located; the inner circumferential surface of the apparatus body housing (110) is coated with a photocatalyst coating (160); a photocatalyst exciting light source (150) is disposed on the outer circumferential surface of the individual lighting assembly (120); air flowing in the ventilating flow passage (140) is purified by means of photo-catalytic oxidation.

Description

technical field [0001] The invention relates to a personal cockpit ventilation and lighting device, more specifically, the present invention relates to a personal cockpit ventilation and lighting device which combines the purification of air in the ventilation duct with the illumination of the personal cockpit by using the principle of photocatalyst. Background technique [0002] The air quality in the cockpit of a civil airliner directly affects the comfort of passengers, and some data show that poor air quality will cause common problems such as fatigue, headaches and sore throats among crew members and passengers. On the other hand, the air recirculation system used to save energy reintroduces the air exhausted from the cabin into the cabin for ventilation, making the air quality problem even more serious. [0003] As we all know, a photocatalyst is a substance that does not change itself under the irradiation of light, but can promote chemical reactions. Under the irrad...

Problems solved by technology

[0015] However, the photocatalyst devices of the single channel type extended surface type in the above three situations all have the following disadvantages: the air flowing in the channel will be subject to a large flow resistance, and in the field of ventilation systems that are more sensitive to the flow resistance, such as vehicles. In ventilation systems, flow resistance requirements are likely not met

[0020] However, the photocatalyst device of the superimposed honeycomb flow channel of the above three situations also has the following disadvantages: the air flowing in the flow channel will be subject to a large flow resistance. In the field of ventilation systems that are more sensitive to flow resistance, such as the ventilation of vehicles system, it is likely that the flow resistance requirement will not be met

However, this idea has not been realized in kind, and its actual effect remains to be verified
