PURPOSE: A method for separating a subambient temperature, especially, a very low temperature using refrigeration generated from multi-ingredient refrigerant fluid is provided to strengthening the efficiency by refrigeration generated and used ranges over a wide temperature, especially, refrigeration of specific temperature including a very low temperature. CONSTITUTION: A method for separating a subambient temperature, especially, a very low temperature using refrigerant generated from multi-ingredient refrigerant fluid includes the steps of compressing the multi-ingredient refrigerant fluid, refrigerating the compressed multi-ingredient refrigerant fluid to at least partially condense the multi-ingredient refrigerant fluid, swelling the refrigerated and compressed multi-ingredient refrigerant fluid to generate refrigeration, using the refrigeration for maintaining the low temperature condition to fluid mixture, separating the fluid mixture into at least one high volatile vapor ingredient and at least one low volatile liquid ingredient, and retrieving at least one of the high volatile vapor ingredient and low volatile liquid ingredient.
