Embodiment 1

[0013] Embodiment 1, the environment in certain aircraft cabin 3 is hot and humid environment, this moment can pass into cabin 3 by the air outlet 1 on the pipeline 2 the cool air that is lower than the dew point temperature of hot and humid environment. Observe the shape of the mist formed at each air outlet 1. If the shape of the fog at each air outlet 1 is consistent, it can be considered that the air distribution in the cabin is uniform.

Embodiment 2

[0014] Embodiment 2, the environment in a certain aircraft cabin 3 is a hot and dry environment. At this time, humidify the cabin first, and then pass into the cabin 3 through the air outlet 1 on the pipeline 2. Cooling air lower than the dew point temperature of the hot and humid environment is passed into the cabin 3. Air. Observe the shape of the mist formed at each air outlet 1. If the shape of the fog at each air outlet 1 is consistent, it can be considered that the air distribution in the cabin is uniform.

[0015] In Example 2, another method can be used to humidify the cabin: before blowing air from the air outlet, it is not necessary to humidify the air in the cabin in advance, but instead, when blowing air from the air outlet, the air itself is humidified air .

Embodiment 3

[0016] Embodiment 3, the environment in a certain aircraft cabin 3 is a dry and cold environment, and now the air outlet 1 on the pipeline 2 can pass into the cabin 3 hot and humid air higher than the dew point temperature of the dry and cold environment. Observe the shape of the mist formed at each air outlet 1. If the shape of the fog at each air outlet 1 is consistent, it can be considered that the air distribution in the cabin is uniform.

[0017] In Embodiment 3, another method may be used for humidifying the cabin: when blowing air from the air outlet, the blown air itself is not humidified air, and instead the air is humidified in the cabin in advance before blowing air from the air outlet.

Abstract

Relating to the environmental control field, the invention provides a method for verifying cabin air distribution uniformity to solve the inaccuracy and pollution problems of existing methods for verifying cabin air distribution uniformity. The technical scheme involved in the invention includes: introducing air able to form fog into the cabin according to the temperature and humidity environment in the cabin, and observing the cabin air distribution uniformity by observing fog distribution. The method provided by the invention utilizes the principle that cold and hot air can intersect to form fog under certain humidity, and employs nontoxic fog to replace traditional colorful smoke or wind speed measurement. Being visual, the method has the advantages of no pollution, easy observation and easy realization, the method is suitable for various aircrafts.

Description

technical field [0001] The invention relates to the field of environment control, in particular to an intuitive method for verifying the uniformity of air distribution in a cabin. Background technique [0002] At present, there are two main methods to verify the uniformity of air distribution in the nacelle at home and abroad: one is to measure the wind speed of each air outlet in the nacelle; the other is to spray colored smoke in the nacelle and observe the shape of the colored smoke at each air outlet. The former method is likely to cause measurement errors and is not intuitive due to the influence of the wind speed at the air outlet and the wind speed measurement position; the latter method is likely to cause environmental pollution. Contents of the invention [0003] The object of the present invention is to provide an intuitive method for verifying the uniformity of air distribution in the cabin. [0004] The technical solution of the present invention is: an intuit...
