A flash tank economizer containing a first expansion device to expand high pressure refrigerant from a system condenser to an intermediate pressure and a second expansion device for further expanding liquid refrigerant at the intermediate pressure that has collected in the tank to a desired low pressure for delivery to the system evaporator. Vapor phase refrigerant produced by the first expansion in the tank is injected back into the system compressor at the intermediate pressure.

A method of expanding a high pressure liquid refrigerant from a condenser of a refrigeration system to a lower pressure and temperature for delivery to the system evaporator that includes the steps of carrying out a first expansion of high pressure refrigerant from a system condenser within an economizer tank to bring said refrigerant to an intermediate pressure and temperature, separating the liquid refrigerant from the refrigerant vapor in said economizer tank after said first expansion, carrying out a second expansion of the separated liquid refrigerant in said tank to bring the separated refrigerant to a desired low pressure and temperature, and delivering said twice expanded low pressure refrigerant to a system evaporator.
