The conditioning of building structures and the like by "exterior surface cooling" which takes advantage of heat flow from hot to cold areas for minimizing the energy required to condition the building interior. The exterior surface of the building is subjected to the flow of air which eliminates penetrating heat at the surface of the building structure, particular advantage being derived from the useful employment of otherwise waste evaporative air discharge from dry-air evaporative cooling, utilized with this invention both for sensible conditioning of the building interior and for surface cooling of the building exterior. BACKGROUND In the construction of buildings and the like such as trailers and motor homes and commercial structures as well, air conditioning is ordinarily excessively energy consuming commensurate with the inability of such structures to reject heat. It is solar heat which is of particular concern, that penetrates the structural surfaces and accumulates within the building interior, particularly closed buildings. Mechanical refrigeration and its sensible cooling process involves an energy change by lowering the air temperature without changing humidity; the net result being a subtraction of energy from the air processed, and at a commensurate cost rate according to the work performed. The evaporative cooling process involves no energy change, in that the decrease of energy in the treated air as a result of temperature decrease therein is regained in the form of humidity, and operates at a commensurately lesser cost rate according to the work performed. However, dry-air evaporative cooling advantageously employs two columns of air, using the evaporation of water as the means of absorbing heat while maintaining separation between the columns of air, so that one column remains evaporatively cooled and the other sensible cooled. Since the cost of evaporative cooling is far less than that of mechanical refrigeration, it is advantageous to employ dry-air evaporative cooling and its costs savings as a means for lowering air temperature in the building structures as hereinafter described. The concept of this energy conservation housing involves the advantageous heat flow from hot to cold areas utilized to minimize the energy required to cool or heat a contained environment. By covering the exterior surface of a building with a moving layer of air, means is provided controlling heat coming to or through the surface. In order to remove heat, cooled air is moved so as to eliminate heat as it comes to the surface of the structure. In order to apply heat, tempered air can be moved to add heat to the surface of the structure. Thus, efficient interior temperature conditioning of the structure is attained. The severe heat that is collected inside a home or recreational vehicle when kept closed during the day is eliminated by the cooling process hereinafter disclosed, since it rejects heat as it approaches or penetrates the exterior surface and thereby controls the internal temperature of the structure which would otherwise act as a heat sink continually absorbing solar heat eliminated only when the sun goes down. Furthermore, structures that have been insulated against heat are then hindered in reflecting heat, since the insulation then slows any cooling process and an air conditioner must overwork so as to maintain a comfortable internal temperature. By preventing heat from getting into the structure or through the usual insulation, by rejecting the heat at the surface as it is accomplished by the present invention, the energy required to cool or to heat the conditioned space is minimized and energy is conserved, this being the primary object of the present invention. |

DETAILED DESCRIPTION I claim: 1.
A process of rejecting heat at the exterior surface of a building structure, comprising the moving of a blanket of evaporatively cooled humidified air coextensively contiguous to and across the exterior surface thereof subject to the penetration of radiant heat, whereby heat radiating toward the exterior surface is absorbed by evaporative drying of the humidified air and carried off thereby.
2.
The process of rejecting heat at the exterior surface of a building structure as set forth in claim 1 and wherein the evaporatively cooled air is moved in parallel columns through channels in the exterior surface, whereby the evaporative drying is achieved by confinement.
3.
A process of rejecting heat at the exterior of and to air condition a building structure, comprising moving two columns of air through a dry-air evaporative cooler, a first column of air being evaporatively cooled and tranferring heat from a second column of air which is thereby sensible cooled, discharging the first column of evaporatively cooled humidified air coextensively as a blanket contiguous to and across the exterior surface of the building structure subject to the penetration of radiant heat to absorb the same by evaporative drying of the humidified air, and moving the second column of sensible cooled air into the building interior to condition the same.
4.
The process of rejecting radiant heat and of air conditioning a building structure as set forth in claim 3 and wherein the evaporatively cooled air is moved in parallel columns through channels in the exterior surface, whereby the evaporative drying is achieved by confinment.
5.
In combination with a building structure having an exterior surface subject to the penetration of radiant heat and a closed interior to be air conditioned, a dry-air evaporative cooler with means evaporatively humidifying and cooling a first column of air while transferring heat from and thereby sensible cooling a second column of air, blower means discharging the first column of evaporatively cooled air coextensively contiguous to and across the exterior surface to absorb heat by evaporative drying of the humidified air to carry off heat from said exterior surface, and blower means moving the second column of sensible cooled air into the building interior to condition the same
