Title: High efficiency refrigeration system

Abstract: An improved evaporator for a refrigeration system to reduce the temperature of a medium therein in which a first tube composed of a first material having a first thermal conductivity is surrounded by a body of a second material disposed in intimate contact therewith, the second material having a different thermal conductivity than the thermal conductivity of the first material. An evaporator refrigerator inlet and outlet are disposed in the body and a refrigeration path intermediate the inlet and outlet includes a plurality of fins in the path to increase the surface area of the second material in the path. A refrigeration system using the improved evaporator and including a subcooler, is described and a method of manufacturing the evaporator is disclosed.
