Apparatus for cooling components or subassemblies of equipment at one or mor e locations comprises one or more first and one or more second reactors, remote from said equipment, each reactor containing a complex compound of a polar refriger- ant and a metal salt a first heater in said first reactor and a second heate r in said second reactor for heating the complex com- pound therein, respectively, a condenser, remote from said equipment, for converting gaseous refrigerant to a liquid phase, and means for cooling said condenser with ambient air, one or more evaporators, each in heat exchange communication with one or more of said components or subassemblies within said equipment, valve means cooperating with first conduit means for alter- nately directing polar refrigerant from said first and said second reactors, respectively, to said condenser, and second conduit means for directing ammonia from said condenser to said one or more evaporators and third conduit means for directing ammo- nia from said one or more evaporators to said first and said second reactors . Alternatively, the apparatus comprises a first reactor located at a remote location from said equipment, and a second reactor locat ed in heat exchange communication with a compo- nent or subassembly of said equipment, each of said first orsecond reactors containing a different complex compound of a polar refrigerant and a metal salt, wherein the equilibrium temperature of the complex compound in said first reactor differs from the equilibrium temperature of the complex compound in said second reactor by between about 10 .degree.C and about 150 .degree.C at the same operating pressure, heating means for heating a complex compound in said fir st reactor, and conduit means for directing polar refrigerant between said reactors.
