Cold generating apparatus, wherein it comprises a cold storage enclosure filled with a material having a solid-liquid transmission in the vicinity of the operating temperature of the apparatus, a first panel forming a radiating surface, whose radiation drops into at least one of the atmospheric windows, a substantially vertical second panel immersed in the material of the cold storage enclosure, a pipe in the form of a coil on each of the first and second panels, said pipes being connected by plastically deformable couplings to form a closed circuit and a certain quantity of a fluid which is vaporizable under the operating conditions of the apparatus within the closed circuit, the assembly constituted by the first and second panels, the closed circuit and the heat transfer fluid forming a device of the heat pipe type serving as a thermal diode which only transmits heat in the direction from the storage enclosure to the radiating surface.

Modular cold generating apparatus

The installation comprises at least one inclined thermal enclosure, forming all or part of the roofing of the dwelling, bounded by an inner roof element, essentially constituted by a collector material of very low thermal mass, absorbing radiation of the solar radiation type of wave length comprised between 0.25 and 4 microns. An outer covering element also of very low thermal mass, is essentially constituted by a material, preferably transparent to solar radiation and behaving as an opaque body to infra-red radiation of wave length comprised between 4 and 30 microns and so capable of emitting this radiation. This outer covering element has water and air sealing properties. This thermal enclosure is connected at its upper part to an upper duct forming a chimney directed upwards and provided with a closure member and, at its lower part, to a lower duct directed downwards and opening into the dwelling through at least one orifice. This thermal enclosure is connected at its upper part to a circulation duct opening into the dwelling and provided with a closure member in the vicinity of its opening.
