The invention relates to the design of an air cooled absorption machine. Said machine has a hollow design via which air can circulate inside same by forced convention having a parallelepiped form. The air enters by suction via the sides and leaves via the upper face of the machine, where the ventilator is located. The machine comprises falling-film heat exchangers with improved designs for heat and mass transfer.

The invention relates to a system for the storage and recovery of thermal energy, using, as its medium, at least one phase change material (solid-liquid) and a sensible heat solid material for storing/recovering the heat obtained from an external source in the form of phase change latent heat and sensible heat. The aforementioned materials are duly housed inside a single tank containing at least two zones which are differentiated by the range of temperatures to which they are subjected, each zone containing a different material. The most common configuration consists of three different zones located inside the tank, namely: a hot zone in the upper part of the tank, enclosing an encapsulated phase change material characterized by a high melting temperature; a cold zone housed in the lower part of the tank, containing a phase change material with a low melting temperature; and a middle zone containing a sensible heat solid material.
