Problems solved by technology

[0010] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, solve the problem of blowing sensation and insufficient fresh air caused by short-distance air supply in a small space, and provide a jet impinging air supply method suitable for capsule hotels, which can Make the air supply speed attenuate rapidly and the fresh air reach the breathing area in time, avoiding the blowing feeling caused by ventilation and the stuffy feeling caused by the lack of fresh air

Embodiment 1

[0027]The size of the "capsule" hotel is 220cm long x 110cm wide x 120cm high; the air supply duct 2 is 10cm long x 10cm wide x 20cm high; the air supply outlet 1 is 10cm long x 10cm wide; The distance is 20cm; the air outlet speed of air outlet 1 is 1m / s, the air supply temperature is 23°C, and the ambient temperature is 25°C;

[0028] 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.

[0029] The standard k-ε model is a two-equation model in which μi is determined by the turbulent kinetic energy (k) equation and the turbulent kinetic energy dissipation rate (ε) equation.

Embodiment 2

[0048] Others are the same as in Example 1, changing the air supply speed to 2m / 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 update speed is faster than that of Example 1, the air age in the breathing zone is about 120s, and the fresh air volume is more sufficient.

Embodiment 3

[0050] 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 0.4m / s, and the air age in the breathing zone is about 100s.

[0051] Based on the above data, the following conclusions can be drawn: the greater the velocity of the air supply jet, the greater the velocity of the breathing zone at the bottom of the "capsule" space, 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 as much as possible without generating 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 rate of the air flow is increased by using the air blowing method. The air supply method invented can increa...

Abstract

The invention discloses a method for jet flow striking-type air supplying suitable for a capsule hotel. The middle position at the top part of a wall surface opposite to the inlet of an independent space of the capsule hotel is provided with two air supply outlets; the air supply outlets are close to the wall surface opposite to the inlet of an independent space of the capsule hotel and supplies air along the horizontal direction; after the air supply flow is ejected horizontally along an air supply port, the air flow hits against the side wall surface of the independent space of the capsule hotel, the air flow after being subjected to the hit vertically attaches to the side wall surface of the independent space of the capsule hotel and supplies air downward, the air flow enters the humanbody respiratory region finally at a low speed, and the horizontal attached-type air supplying is formed. According to the invention, the problems of air blowing sense and shortage of fresh air caused by air supplying for a close distance in a small space are solved, the method is suitable for a close distance air supplying and a small space air conditioning occasion with a higher comfort requirement, the air blowing sense caused by air ventilation and oppressed sense caused by shortage of fresh air are avoided, the air supplying comfort is ensured, and also the effect of saving using space and energy conservation can be achieved.

Description

technical field [0001] The invention relates to an air supply method, in particular to an air supply method suitable for capsule hotels based on the principle of jet impact. The invention is especially suitable for indoor ventilation systems in small spaces such as 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 ...
