FIELD : sorption engineering and sorbents. SUBSTANCE : invention is intended for use in adsorption-type cooling machines and thermal pumps. Methanol vapor sorbent according to invention contains, as porous matrix, inorganic oxides, porous coals, naturally occurring sorbents or their mixtures, and an active substance placed in matrix pores and capable of providing reversible methanol vapor adsorption-desorption processes, which substance is selected from series : halide and nitrates of alkali, alkali-earth, and iron subgroup metals. A method of producing cold by means of adsorption-cooling apparatus is described, wherein methanol vapors are used as adsorbed substance and, as sorbent, above defined sorbent. EFFECT : increased sorption capacity of methanol vapor sorbent. 2 cl, 10 ex
