Abstract

PURPOSE:To protect hot-water from contaminated air by a method wherein the air is blown against the outside of a pipe made of a permeable material through which pipe the hot-water is flowed and the water soaked out to the outside of said pipe is evaporated to cool said hot-water by the latent heat of evaporation. CONSTITUTION:In a circulating system, in which the hot-water, exchanged the heat thereof in a refrigerating machine, is passed through the inside of the permeable pipes 2 to collect it into a lower water tank 3 from an upper water tank 1 and is circulated by sending it to the refrigerating machine from a take-out port 4 by means of a pump, the outlet side of the pipes 2 of the permeable material is provided with a punching plate 9 so as to regulate to fill the permeable material with the water due to the proper diameters of the holes thereof. In this case, the water soaked out of the pipes 2 is evaporated forcedly by the air sucked by a fan 7 through a louver 5 and whereby the circulating water is cooled by the latent heat upon evaporation.

There are closed cooling towers that cool circulating water by separating it from the atmosphere.

The present invention relates to a so-called semi-closed type cooling tower that cools most of the circulating water without directly contacting the atmosphere, and a part of the circulating water is cooled by a group of pipes made of a permeable material. It oozes out and is cooled by evaporation into the air, creating a temperature difference with the circulating water in the pipes. Because of the water flow and temperature difference inside and outside the pipe, the circulating water is cooled and protected from contaminated air without absorbing airborne pollutants.

In this system, the pipe (2) made of permeable material has a punching plate on the outlet side. (9), and adjust the permeable material to be filled with water by adjusting the appropriate hole diameter.
