Abstract: 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 r
