Refrigeration equipment

Abstract

The invention relates to a simple point refrigeration device, which is suitable for use outside semi-rooms such as station platforms on the ground, outdoors such as supermarket rooftops and entertainment facilities waiting areas, and in large spaces such as factories where air conditioning cannot be carried out in the entire venue. An outdoor air intake port (7a) is formed on one side, and a blowout port (7b) is formed on the other side. In order to inject water from a vertical or horizontal cylindrical passage (5) with both ends open, A dry bulb hygrometer or a relative humidity meter (11) is arranged on the side wall of the outdoor air inlet (7a) within a predetermined interval S with a sufficient distance to evaporate the spray water ejected from the nozzle, and in the cylindrical passage (5 ) is equipped with a wet bulb thermometer (12) and a water spray nozzle assembly (8), and a fan (10) is installed in the cylindrical passage (7) other than the section (S). The spray water from the water spray nozzle assembly (8) is sprayed in a direction opposite to the air blowing direction of the fan (10), and the cold air that adjusts the temperature and humidity of the outdoor air is blown out from the blower outlet (7b), and the point is Refrigeration. Calculate the actual temperature difference between the measured values ​​of the dry-bulb thermometer or relative humidity meter (11) and the wet-bulb thermometer (12). If the difference is greater than a certain value, determine the humidity of the outdoor air before spraying to a certain value. When it is below the standard, the sprayed water droplets can be fully vaporized, thereby controlling the amount of water spray.

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
