Abstract

Procedimiento y aparato para regular la humedad relativa del ambiente de un terreno, regula el flujo de agua a un medio ambiente con el fin de mantener la humedad relativa en el medio ambiente a un valor previamente elegido, procedimiento caracterizado porque comprende, detectar un aumento o reducción en la humedad ambiental con relación al vapor previamente elegido, por medio de hinchamiento o contracción osmóticos de una material capaz de hincharse no menos de aproximadamente 25 veces su volumen en seco cuando está en equilibrio con agua o una humedad relativa del 100% en el cual el hinchamiento o contracción obstruye o libera, respectivamente, el flujo de agua al medio ambiente mantenido, por lo tanto , la humedad relativa al valor previamente elegido.
