Method And Device For Regulating The Temperature And Relative Humidity In A Building

Abstract

A method and device are provided for regulating the temperature and relative humidity of the air in a building having microporous external walls and external thermal insulation, including air circulation spaces provided between the walls and the thermal insulation, and a device for supplying the spaces with a controlled air flow, the device configured for supplying the spaces with air substantially saturated with water vapour.

1 . Method for regulating the temperature and the relative humidity of the air in a building with microporous walls and with external thermal insulation, air circulation spaces being arranged between the external thermal insulation and the walls, which it consists in regulating the relative humidity of the air admitted into said spaces, via heating or via cooling and/or by passing in humidifying means arranged upstream of the air circulation spaces. 
     
     
         2 . Method according to  claim 1 , wherein it consists in passing in the humidifying means fresh air taken from outside the building, or air extracted from the building or a mixture of fresh air taken from outside and of air extracted from the building. 
     
     
         3 . Method according to  claim 1 , wherein the air exiting the humidifying means is intermittently blown inside the building in order to increase the relative humidity of the air in the building. 
     
     
         4 . Method according to  claim 1 , wherein the air exiting the humidifying means is substantially saturated with water vapour. 
     
     
         5 . Device for regulating the temperature and the relative humidity of the air inside a building with microporous walls and with external thermal insulation, comprising means for controlling the intake of air into spaces arranged between the external thermal insulation and the microporous walls, wherein it further comprises means for regulating at a desired value the relative humidity of the air admitted in the aforementioned spaces, via heating or via cooling or by passing in humidifying means. 
     
     
         6 . Device according to  claim 5 , wherein the humidifying means include a hot water tank and means for heating water with solar or geothermal energy or heat recovery. 
     
     
         7 . Device according to  claim 5 , wherein it comprises means for supplying humidifying means with air taken from outside the building or with air taken from inside the building or with a mixture of air taken from outside the building and of air taken from inside the building. 
     
     
         8 . Device according to  claim 6 , wherein the humidifying means are supplied with air by a double-flow controlled mechanical ventilation installation, comprising means for sucking air inside and outside the building and for blowing air inside the building and in said spaces between the walls and the external thermal insulation. 
     
     
         9 . Device according to  claim 8 , wherein the controlled mechanical ventilation installation comprises at the outlet a caisson with two channels connected respectively to air inlet means in said spaces and to air inlet means inside the building. 
     
     
         10 . Device according to  claim 8 , wherein the humidifying means are mounted between means for exchanging heat between the air taken from outside the building and the air taken from inside the building, and means of backup heating of the blown air.
