Abstract

An air ventilating system for use to ventilate and dehydrate and dehumidify the insulation immediately under the roof structure. The system includes an air intake member, to draw in relatively dry air, generally located above the roof surface, and a central distribution member, in the form of a plenum, disposed above or below the roof structure, and a plurality of radiating pipes that lead from the distribution plenum member, and which are located above, below or at the same level as the insulation layer under the roof structure, with such distribution pipes having a plurality of small openings therein to disperse air to the surrounding insulation layers for purposes of aerating same to remove moisture from the insulation. The system includes a humidity and temperature sensing device to detect the relative moisture content and temperature levels of the air both within and external to the roof infrastructure, with automatic sensing means to turn on or off the dehumidifying system at intervals dependent on predetermined temperature levels and humidity levels both within and outside the building.

Claims2

Dependent claims

An air ventilation system for a roof infrastructure for a building comprising:

(a) an air intake member disposed adjacent said building;
(b) mechanical power means on said air intake member adapted to activate the flow of intake air into said building and its roof infrastructure;
(c) air distribution pipes connected to said air intake member adapted to disburse air into the roof infrastructure;
(d) air outlet means on said building to vent air therefrom and from roof infrastructure;
(e) thermostat sensor means affixed outside said building, said thermostat sensor means connected electrically to said mechanical power means to signal and cause activation of said mechanical power means to draw air into the air intake member and into the building, said thermostat sensor means adapted to send an electrical signal to said mechanical power means to activate same whenever the temperature level in the outside of the building reaches a predetermined level;
(f) first humistat sensor means located outside the building and adapted to sense relative humidity levels outside the building, said first humistat sensor being electrically connected to said mechanical power means to signal and cause activation of said mechanical power means to draw air into the air intake member and into the building, said first humistat sensor adapted to send an electrical signal to said mechanical power means to activate same whenever the relative humidity level outside the building reaches a predetermined level;
(g) second humistat sensor means located inside the building and adapted to sense relative humidity levels inside the building, said second humistat sensor being electrically connected to said mechanical power means to signal and cause activation of said mechanical power means to draw air into the air intake member and into the building, said second humistat sensor adapted to send an electrical signal to said mechanical power means to activate same whenever the relative humidity level inside the building reaches a predetermined level.
