<p>The invention relates to a process and a cooling installation with heat sources of low thermic level. According to the invention, the process consists in truncating a cycle with co-absorber, so that, between the stages with coupled low pressure processes, of desorption and absorption, and of high pressure generating and resorption, the absorber of unique average concentration, generated by the mixture of the absorbers coming from the low pressure processes, undergo some stages i=1, 2, ..., n-1, of coupled isobar processes, of generating and resorption, with increasing pressure, fed in a preestablished manner by mixtures of the absorbers of unique average concentration, with that coming from the generation of the stage i=2, for the stage i=1, of that coming from the resorption of the stage i-1, with that coming from the generation of the stage i+1, for the stages i, and with that coming from the resorption of the stage i=n-1, for the stage of high pressure and processes of increasing, decreasing pressure, recovery of heat between stages, release between the high and low pressure and desorption of the absorber for cooling, in order to close the cycle. According to the invention, the installation comprises a desorber (1) and an absorber (9) of low pressure, and a generator (27) and a resorber (8) of high pressure. The absorber of unique average concentration (20) is formed in a mixer (19), by the absorbers of the low pressure processes and, by means of some pumps (21, 36), some taps (15, 29) and some gas and solution thermal recovery means (16, 17), pass through an intermediary pressure stage, with a coupled generator (14) and resorber (33) coupled, fed in a preestablished manner by an absorber (30) consisting of a mixer (23) and the absorber (20) of unique average concentration and resulting from the generator (27), in order to be released, in the end, into a tap (10), between the high and the low pressure, and produces the cooling in the desorber (1).</p> |
