The steam jet refrigeration cycle is similar to the conventional vapour compression cycle except that the compressor is replaced by a liquid feed pump, boiler/vapour-generator, and ejector-pump as shown in Figure 2.4 [15]. The system, watery liquid is vaporized at high pressure a boiler fed to an ejector where it entrains a low pressure vapour originating from the evaporator. The combined liquid flow is then compressed to an intermediate pressure equal to that of the condenser. This refrigeration cycle has drawn renewed attention due to its simplicity of construction, ruggedness and few moving parts.
