Abstract
A refrigeration process comprising, 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.
