Principle to avoid condensation theory of non-permissive insulations reference temperature

Abstract

This patent represents the method in which the condensation is avoided in a thermal insulated envelope. The maintaining of warm vapors in a warm zone of a vapor-impermeable insulation lids to the elimination of condensation phenomenon. This is realized by extending the properties of Vapor Impermeable Insulations (VII) to the entire surface of a wall or by creating a Non-Permissive Insulation Assembly (NP-IA). Through the fact that this configuration of insulations makes it possible the avoidance of condensation in any situation in which is applied a difference of temperatures, occurs the utility of enunciating a principle to avoid condensation as fundamental method for designing enclosures. Also, is justified the record of a reference temperature towards which can be defined the terms warm and cold in relation to an optimal temperature for development of human activity.

1 . A method for avoiding condensation in insulated enclosures constructed and subjected to significant differences of temperature, characterized in that, in order to avoid condensation the heat flow must convert the heat deficit in an insulation material or insulation assembly without vapor diffusion or any airflow carrying warm vapor to cold areas of insulation. 
     
     
         2 . A method for avoiding condensation according to  claim 1 , characterized in that, the insulation applied to a envelope wall having permeable characteristics to water/air/vapors, is configured as a Vapor Impermeable Insulation (VII) or a Non-Permissive Insulation Assembly (NP-IA).
