062007000 | UTILIZING FUEL AS REFRIGERANT | 8 |
20080276627 | FUEL GAS SUPPLY SYSTEM AND METHOD OF A SHIP - A fuel gas supply system of a ship is provided for supplying fuel gas to a high-pressure gas injection engine of the ship, wherein the ship has an LNG fuel tank for storing LNG as fuel and LNG is extracted from an LNG fuel tank of the ship, compressed at a high pressure, gasified, and then supplied to the high-pressure gas injection engine. | 11-13-2008 |
20110056216 | Pulsed Propane Refrigeration Device and Method - Embodiments of the disclosed technology comprise a combination refrigeration and combustion system including a tank that holds liquefied gas, an expansion valve in fluid connection with the tank, and a sealable chamber housing an evaporator, with the evaporator in fluid connection with the expansion valve. The system is configured for expulsion of the liquefied gas from the tank into the expansion valve. The expulsion takes place in at least one pulse over part of a defined time interval. After an expulsion of gas, the liquefied gas expands into gaseous form in the evaporator, allowing for continuous combustion of the gas in gaseous form. | 03-10-2011 |
20110219786 | FLUID HEAT SINK POWERED VAPOR CYCLE SYSTEM - An aircraft cooling system includes a refrigerant cycle including a first heat exchanger, a second heat exchanger, and a compressor. A component of the aircraft is in thermal communication with the first heat exchanger. A heat sink fluid passes through the second heat exchanger to absorb heat from the refrigerant cycle. A hydraulic motor is mechanically connected with the compressor and powered by the heat sink fluid, which is circulated by a pump. | 09-15-2011 |
20130055728 | Refrigeration Vehicle and Method for Cooling its Refrigeration Space Using a Low-Temperature-Liquefied Combustible Gas - The present invention relates to a refrigeration vehicle comprising at least one refrigeration space, which can be cooled via at least one supplemental heat exchanger. The supplemental heat exchanger in the refrigeration space is connected to other components, preferably via couplings and flexible lines, establishing a heat exchange loop being able to exchange heat with an evaporator for low-temperature liquefied combustible gas. Moreover the Refrigeration vehicle comprises at least one first vehicle part and one second vehicle part being dividable and wherein the first vehicle part comprises an internal combustion engine and the evaporator for the low-temperature liquefied combustible gas. The refrigeration vehicle in addition comprises a first nitrogen tank for liquid nitrogen and a nitrogen heat exchanger as well as a boil-off device in the first vehicle part for joint storage and/or transportation of low-temperature liquefied combustible gas and liquid nitrogen by keeping the combustible gas cooled in a fuel tank indirectly or directly by the liquid nitrogen. The invention relates, furthermore, to a refrigeration method for refrigerating at least one refrigeration space of a refrigeration vehicle via at least one supplemental heat exchanger. Heat is extracted from the refrigeration space via the supplemental heat exchanger and conducted via a heat exchange loop to an evaporator, for evaporation of low-temperature liquefied combustible gas, especially liquefied natural gas, which is afterwards supplied to an internal combustion engine of the refrigeration vehicle. The present invention is especially suitable for refrigeration transporters operated with natural gas, which are used for the distribution of frozen and chilled goods to retail dealers. In particular the economic employment of a combustion engine operated with natural gas in a transporter, storing the natural gas in the liquid phase, and the combined use of this cold for cooling a refrigeration space is highly advantageous, because the amount of energy needed all in all can be explicitly lowered. Moreover, using the boil-off device in the tractor is particularly advantageous, because a simultaneous, combined filling mode for liquid nitrogen and natural gas at a corresponding filling station unit becomes possible, realizing an extraordinary increase in efficiency. | 03-07-2013 |
20140069117 | NON-EXPLOSIVE MIXED REFRIGERANT FOR RE-LIQUEFYING DEVICE IN SYSTEM FOR SUPPLYING FUEL TO HIGH-PRESSURE NATURAL GAS INJECTION ENGINE - Provided is a nonflammable mixed refrigerant for use in a reliquefaction apparatus of a fuel supply system that compresses BOG generated in an LNG storage tank to a medium pressure, reliquefies the compressed BOG, compresses the reliquefied BOG to a high pressure, gasifies the compressed requefied BOG, and supplies the gasified BOG to a high-pressure natural gas injection engine. A nonflammable mixed refrigerant for use in a fuel supply system for a high-pressure natural gas injection engine is provided. The nonflammable mixed refrigerant cools the BOG by heat exchange with the BOG in the reliquefaction apparatus. The nonflammable mixed refrigerant comprises a mixture of nonflammable refrigerants with different boiling points, and the boiling point of each of the nonflammable refrigerant ranges between a room temperature and a liquefaction temperature of natural gas. | 03-13-2014 |
20150375869 | ENDOTHERMIC CRACKING AIRCRAFT FUEL SYSTEM - A method of controlling cooling in an aircraft system includes endothermically cracking a fuel to increase its cooling capacity using a catalyst that includes at least one transition metal compound of at least one of carbides, nitrides, oxynitrides, oxycarbonitrides, oxycarbides, phosphides, and combinations, and the transition metal includes at least one of zirconium, hafnium, tantalum, niobium, molybdenum, tungsten, platinum, palladium, rhodium, iridium, ruthenium, osmium, rhenium, and combinations thereof. The cracked fuel is used to cool a heat source that includes an aircraft component. | 12-31-2015 |
20160130019 | METHOD OF COOLING SATLET ELECTRONICS - A method of cooling spacecraft electronics by transferring fuel between two or more satlets is provided. Each satlet's electronics is thermally coupled to the satlet's fuel tank. A controller connected to a temperature sensor determines that a temperature of a first satlet's electronics is reaching, has reached, or exceeds a predetermined threshold. The controller connected to a second temperature sensor determines that a temperature of a second satlet's propellant is lower than the temperature of the first satlet's electronics. The controller then directs the flow of propellant from the second satlet's fuel tank to the first satlet's fuel tank to cool the first satlet's electronics. | 05-12-2016 |
