    Abstract: A refrigerated transport system (20) comprises: an engine (30). A vapor compression system (50) comprises: a compressor (40) for compressing a flow of a refrigerant; a first heat exchanger (60) along a refrigerant flowpath (52) of the refrigerant; and a second heat exchanger (66) along the refrigerant flowpath of the refrigerant. A heat recovery system (56) has: a first heat exchanger (110) for transferring heat from the engine to a heat recovery fluid along a heat recovery flowpath (58); and a second heat exchanger (112; 63) along the heat recovery flowpath. The heat recovery system second heat exchanger and the vapor compression system first heat exchanger are respective portions of a shared tube/fin package.

    Abstract: A heat transfer system cycles between a first mode where a heat transfer fluid is directed to a first electrocaloric module and from the first electrocaloric module to a heat exchanger to a second electrocaloric module while one of the first and second electrocaloric modules is energized, and a second mode where the heat transfer fluid is directed to the second electrocaloric module and from the second electrocaloric module to the heat exchanger to the first electrocaloric module, while the other of the first and second electrocaloric modules is energized. The modes are repeatedly cycled in alternating order directing the heat transfer fluid to cause a temperature gradient in each of the first and second electrocaloric modules, and heat is rejected to the fluid from the heat exchanger or is absorbed by the heat exchanger from the fluid.

    Abstract: A method of measuring concentrations of gas mixtures is disclosed in which an ionic liquid and/or low vapor-pressure organic solvent is exposed to a gas mixture being tested to form a solution of the gas components in the liquid. The vapor pressure of the solution is then measured at one or more other temperatures and compared to predicted vapor pressures based on known individual vapor pressure profiles of the gas components in the liquid in order to determine the actual proportions of the components in the gas sample.

    Abstract: A method of operating a heat transfer system includes starting operation of a first heat transfer fluid vapor/compression circulation loop including a fluid pumping mechanism, a heat exchanger for rejecting thermal energy from a first heat transfer fluid, and a heat absorption side of an internal heat exchanger. A first conduit in a closed fluid circulation loop circulates the first heat transfer fluid therethrough. Operation of a second two-phase heat transfer fluid circulation loop is started after starting operation of the first heat transfer fluid circulation loop. The second heat transfer fluid circulation loop transfers heat to the first heat transfer fluid circulation loop through the internal heat exchanger and includes a heat rejection side of the internal heat exchanger, a liquid pump, and a heat exchanger evaporator. A second conduit in a closed fluid circulation loop circulates a second heat transfer fluid therethrough.

    Abstract: A system has: a compressor having a suction port and a discharge port; an ejector having a motive flow inlet, a suction flow inlet, and an outlet; a separator having an inlet, a vapor outlet, and a liquid outlet; a first heat exchanger; an expansion device; and a second heat exchanger. Conduits and valves are positioned to provide alternative operation in: a cooling mode and a heating mode. In the cooling mode, a needle of the ejector is closed. In the heating mode refrigerant passes sequentially from a first section of the second heat exchanger to a second section. In the cooling mode refrigerant passes in parallel through the first section and the second section.
