ABSTRACT:
A refrigeration process comprising: compressing low pressure vapor refrigerant to a higher temperature and pressure vapor, compressing low pressure vapor refrigerant to a higher temperature and pressure vapor, condensing the higher pressure vapor refrigerant into a liquid refrigerant at the higher pressure, thermally isolating the higher pressure liquid, cooling the thermally isolated liquid refrigerant while remaining thermally isolated and then allowing thermal contact of the remaining low temperature and pressure liquid and a cooled substance causing the low temperature and pressure liquid to further reversibly boil to a vapor at the low pressure.
