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.
Claims6
A refrigeration process comprising the steps of:
- compressing a low pressure vapor refrigerant to a higher temperature and pressure vapor refrigerant,
- condensing the higher pressure vapor refrigerant into a liquid refrigerant at the higher pressure,
- thermally-isolating the liquid refrigerant,
- evaporatively cooling the liquid refrigerant while the liquid refrigerant remains thermally-isolated to form a cooled liquid refrigerant,
- powering an engine with a pressure difference between the liquid refrigerant and the low pressure vapor refrigerant, and
- then allowing thermal contact of the cooled liquid refrigerant and a substance to cool the substance.
A refrigeration system comprising:
- at least one compressor for compressing a low pressure vapor refrigerant into a higher temperature and pressure vapor refrigerant,
- at least one condenser for condensing the higher pressure vapor refrigerant into a liquid refrigerant at the higher pressure,
- at least one cooling evaporator from which the liquid refrigerant is thermally isolated for cooling the liquid refrigerant to a lower temperature to form a cooled liquid refrigerant, and
- powering an engine with a pressure difference between the liquid refrigerant and the low pressure vapor refrigerant, and
- at least one evaporator for allowing thermal contact of the cooled liquid refrigerant and a substance to cool the substance.
