Abstract
A non-compression cascade refrigeration system,for refrigerating a closed refrigerated space includes a cascade condenser,in heat exchange relationship with a primary evaporator,, a cascade evaporator,positioned in the refrigerated space,and a liquid and vapor separator,. A first coolant delivery conduit,delivers liquid coolant from the cascade condenser,to the separator,which then provides the coolant through a second coolant delivery conduit,to the cascade evaporator,for cooling the refrigerated space,. A first coolant return conduit,returns the coolant from the cascade evaporator,to the separator,where the return coolant is separated into liquid and gaseous coolant, such that the liquid coolant is directed to the second delivery conduit,for reuse in the cascade evaporator,and the gaseous coolant is directed to a second coolant return conduit,and returned to the cascade condenser
