This invention relates to a refrigerating process according to the known compression-absorption method, in which a solution of gas in a liquid absorbent is conducted in a closed cycle from an absorber to an evaporator in which by heat supply thereto a certain amount of gas is expelled from the absorbent and from which the solution having a lower gas concentration and, after compression, the expelled gas are separately recycled to the absorber in which by removal of heat from the solution the recycled gas is again dissolved in the absorbent for restoration of the gas concentration of the solution which is then transferred to the evaporator, and the invention is characterized in that the evaporation of gas from, and the absorption of gas in, the absorbent is continuously effected in the solution along an elongated chamber where a substantial temperature gradient from one end to the other end of the chamber is maintained whereby the compression-absorption process may be effected at a relatively low compression ratio.

A refrigerating process according to the compression-absorption method in which use is made of apparatus comprising a gas evaporator and a gas absorber connected to each other by gas and solution circuit means in a closed system, comprising the steps of (a) feeding in a closed cycle a solution enriched by gas from the absorber (2) to the evaporator (1); (b) supplying heat to said enriched solution in the evaporator for evaporating gas therefrom and producing a gas impoverished solution; (c) feeding said enriched solution to the evaporator; (d) withdrawing evaporated gas from the evaporator and increasing the pressure thereof; (e) introducing said pressure increased gas into the absorber and removing heat from said gas impoverished solution introduced into the absorber under conditions which will ensure therein a higher pressure level than in the evaporator and a lower average temperature of the impoverished solution introduced thereinto than the average temperature of the enriched solution introduced into the evaporator for effecting gas dissolution in the former and gas evaporation from the latter solution, respectively; (f) effecting increase of the temperature of the enriched solution which is fed from the absorber and is introduced into the evaporator and a proportional increase of the temperature of the impoverished solution which is fed from the evaporator and introduced into the absorber by leading said solutions in countercurrent heat exchanging relationship before admixing the enriched solution with solution which is under gas evaporating conditions in the evaporator and admixing of the impoverished solution with the solution which is under gas absorbing conditions in the absorber.
