Problems solved by technology

Since there is only one air outlet at the corner of the wall, if it is used in a small space like a capsule hotel, the distribution of air distribution will be uneven, and the human body will feel uncomfortable due to the difference in the amount of air received on both sides. This invention is suitable for offices, etc. In traditional buildings, it cannot be used in a small space like a capsule hotel

Embodiment 1

[0026] The size of the "capsule" hotel is 220cm long x 110cm wide x 120cm high; the air supply duct 2 is 7cm long x 7cm wide x 15cm high; the air supply outlet 1 is 7cm long x 7cm wide; 1m / s, the supply air temperature is 23°C, and the ambient temperature is 25°C;

[0027] In order to verify the air supply effect and the indoor air flow situation of the air supply method of the present invention, a kind of average turbulence energy model proposed by Launder and Spalding etc. is selected here, that is, the standard k-ε double-equation turbulence model to solve equations.

[0028] The standard k-ε model is determined by the turbulent kinetic energy (k) equation and the turbulent kinetic energy dissipation rate (ε) equation μi two-equation model.

Embodiment 2

[0047] Others are the same as in Example 1, changing the air supply speed to 1.5m / s, then the wind speed in the breathing zone is about 0.3m / s, which will not cause the feeling of blowing. Due to the increase of the air supply speed and the increase of the air supply volume, the air renewal speed is faster than that of Example 1, the air age in the breathing zone is about 180s, and the fresh air volume is more sufficient.

Embodiment 3

[0049] Others are the same as in Example 1, changing the air supply speed to 3m / s, then the wind speed in the breathing zone is about 0.6m / s, and the air age in the breathing zone is about 90s.

[0050] Based on the above data, it can be seen that the greater the velocity of the air supply jet, the greater the velocity of the breathing zone at the bottom of the "capsule", and the smaller the air age; conversely, the smaller the velocity of the jet supply air, the greater the air age in the breathing zone. It shows that when the air supply method of this invention is adopted, a larger air supply speed should be adopted without producing a blowing sensation, so as to ensure the freshness of the air; when the jet flow collides with the wall surface, the velocity attenuation is accelerated, which further shows that the air flow of the invention is adopted. The air supply method can increase the attenuation of the air supply speed, which is beneficial to improve the comfort of the h...

Abstract

The invention discloses a vertical wall-attached air supply method suitable for capsule hotels on both sides. An air supply port is installed at the position of each independent space entrance of the capsule hotel directly opposite to the top of the wall and adjacent to the side wall on both sides. The air supply port Close to the entrances of each independent space of the capsule hotel and directly facing the wall to supply air vertically downward, above the air supply outlet is connected an indoor air supply device composed of an air supply duct, and the air supply duct is connected to the outdoor air supply duct. The invention solves the problems of blowing sensation and insufficient fresh air caused by short-distance air supply in a small space, makes the air supply speed attenuate rapidly and fresh air reach the breathing area in time, and avoids the blowing feeling caused by ventilation and the stuffiness caused by insufficient fresh air feel. The present invention is suitable for short-distance air supply and small-space air-conditioning occasions requiring high comfort, such as the air-conditioning air supply of a capsule hotel, which can ensure that the fresh air reaches the breathing area in time, and at the same time does not produce a feeling of blowing, ensuring the comfort of air supply , but also achieve the effect of saving space and energy saving.

Description

technical field [0001] The invention relates to an air supply method, in particular to an air supply method suitable for vertical walls on both sides of a capsule hotel. The invention is particularly suitable for indoor ventilation systems in small spaces similar to capsule hotels. Background technique [0002] On February 1, 1979, the world's first capsule hotel opened in Osaka. Most capsule hotels are only available in busy urban areas. Because of Japan's terrible overtime culture, the capsule hotel was born. This kind of hotel is dozens of neatly placed "capsules", and each capsule "holds" a customer. In the past two years, capsule hotels in China have flourished in major cities. Each "capsule" has a width and height of about 110 centimeters, a length of about 220 centimeters, a volume of about 2.7 cubic meters, and an average usable area of ​​about 3 square meters per capita. The "capsule" has no door, and residents can draw the curtain at the entrance to block it. It...
