Abstract
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.
