Refrigeration equipment

Abstract

The invention relates to a simple point-type refrigerating device which is applicable to be used outdoor occasions such as stations, outdoor occasions such as supermarket and entertainment facilities waiting positions, and in large-space such as factory which can not be air-conditioned. An outdoor air inlet (7a) is arranged at one side, and an air outlet (7b) is arranged at the other side. A dry bulb hygrometer and a relative hygrometer (11) is arranged at the lateral wall of the outdoor air inlet (7a) which ensures an enough space inside a preset section S so as to vaporize the water spray from a water spraying nozzle arranged inside a vertically-arranged or a horizontally-arranged cylinder-shaped channel (5) whose two ends are open. Besides, a fan (10) is arranged inside the cylinder-shaped channel (7) beyond the section (S). The water which is from the water spraying nozzle assembly (8) is sprayed in such a way of being opposite to the air-feeding direction of the fan (10). The cooling air which is used for adjusting the temperature and humidity of the outdoor air is blown from the air outlet (7b) for refrigerating. The temperature difference between the dry bulb hygrometer or a relative hygrometer (11) and the wet bulb hygrometer (12) is calculated so as to fully gasify the water drops when the humidity of the outdoor air is below a certain reference before spraying on thecondition that the difference is larger than a certain value, thereby controlling the amount of water spraying.

Description

technical field [0001] The present invention relates to a refrigeration device utilizing the latent heat of evaporation of water, in particular to a simple point refrigeration device used in semi-outdoor facilities such as facility waiting places and platforms of stations, or in factories where the entire venue cannot be air-conditioned. Background technique [0002] When it is humid in summer, the inside of the train and the lobbies are cooled for comfort, but the inside of the station and the platform are extremely hot, which is not only uncomfortable for people waiting for the train, but also sometimes affects the health of people waiting for the train due to the heat. Usually, countermeasures against the heat of the semi-outdoors such as stations and platforms are to circulate air or use sun-shading devices such as roofs. However, an effective device for cooling a sufficiently open space is to exchange the air in the space with the outdoor air. , compared with the volume...

AI Technical Summary

Problems solved by technology

[0009] As mentioned above, in the conventional device, since the operability is reduced in the area of ​​cloudy fog, a separator for separating air and water is required, but the remaining water after spraying stays in the device, causing miscellaneous bacteria and bacteria , have problems with hygiene
