A cooling system which uses a jet or ejector pump in place of a mechanically driven compressor includes a working fluid composed of two or possibly more different refrigerants. One has a low saturation temperature while the other has a higher one. The mixture of the two refrigerants is subject to a distillation or separation. Following the separation the low saturation temperature refrigerant (vapor) is condensed in an auxiliary condenser and inducted through the evaporator while the higher saturation temperature refrigerant (liquid) is returned to a boiler for vaporization and subsequent used in the jet pump which produces the pressure reduction via which the low saturation temperature refrigerant is inducted into the evaporator.

In a refrigerating system: a boiler in which a working fluid can be heated to the point of vaporizing; a jet pump, said jet pump being fluidly communicated with said boiler in a manner to receive the high pressure temperature vapor generated therein and create a low pressure zone; a main condenser fluidly communicated with said jet pump for condensing the effluent from said jet pump; a separating unit fluidly communicated with said main condenser for separating the liquified effluent into a first refrigerant having a first saturation temperature and a second refrigerant having a second saturation temperature which is higher than that of the first refrigerant; a pump for pumping the second refrigerant in liquid form from said separating unit to said boiler; an auxiliary condenser for receiving the first refrigerant in vapor form and condensing the same to its liquid state; an evaporator fluidly interposed between said auxiliary condenser and the low pressure zone in said jet pump; and an expansion valve which controls the amount of first refrigerant which is permitted to be inducted into said evaporator.
