A system is described herein for repurposing waste heat from a refrigeration cycle to improve the efficiency of the cycle and power electronic devices. The system may include a compressor, a turbine, an accumulator, a condenser, a throttle, and an evaporator. The accumulator may include a high-pressure chamber connected between the turbine and condenser, and a low-pressure chamber connected between the evaporator and the compressor. The high-pressure chamber may be segregated from the low-pressure chamber such that high-pressure refrigerant in the high-pressure chamber is prevented from mixing with low-pressure refrigerant in the low-pressure chamber. The high-pressure chamber and low-pressure chamber may be thermally coupled such that liquid refrigerant in the low-pressure chamber is vaporized by heat exchange with the high-pressure chamber. The turbine may power an electronic component of the refrigerator or may feed electricity back into a community grid power system.

A turbofan gas turbine engine includes heat exchanger module, fan assembly, compressor, turbine and exhaust modules. The fan includes a plurality of fan blades. The heat exchanger in fluid communicates with the fan assembly by an inlet duct, and the heat exchanger includes a plurality of radially-extending hollow vanes arranged in a circumferential array, with a channel extending axially between each pair of adjacent hollow vanes. An airflow entering the heat exchanger is divided between a set of vane airflows and a set of channel airflows. Each vane airflow has a vane mass flow rate Flow.sub.Vane, and each channel air flow has a channel mass flow rate Flow.sub.Chan. Each hollow vane includes, an inlet, heat transfer, and exhaust portions, with the inlet portion comprising a diffuser element and the heat transfer portion including at least one heat transfer element. The diffuser element causes Flow.sub.Vane to be lower than Flow.sub.Chan.

The present invention provides a heat transport device in which a hydrohaloolefin-containing refrigerant is enclosed in a circulation route, and the heat transport device is capable of reducing the influence of oxygen entrapped in the circulation route. The present invention also provides a heat transport method using the heat transport device. In the heat transport device 1, a refrigerant comprising at least one of hydrofluoroolefins (HFOs), hydrochlorofluoroolefins (HCFOs), or hydrochloroolefins (HCOs) is enclosed in a circulation route, and a stabilizer container comprising an acid scavenger and/or an antioxidant is disposed in the circulation route. The antioxidant is at least one member selected from the group consisting of alkylcatechols, alkoxyphenols, benzoquinones, phenothiazines, and phthalates, and the acid scavenger is at least one member selected from the group consisting of aliphatic alcohols, polyhydric alcohols, amines, terpenes, alkyl epoxides, and alkenyl tolyls.

The present invention is directed to a medical device, specifically, a medical transport container for transporting blood and/or pharmaceuticals, e.g. human or animal medication, which are temperature sensitive, and comprises a forming gel encapsulated within the main storage compartment, which may comprise of one or more removable dividers to accommodate a plurality of blood vials or pharmaceuticals being cooled by a refrigerating element and/or the forming gel, which morphs and conforms to hold the container's inner contents (i.e. pharmaceutical(s), blood, test tube and/or vial(s) and the like) firmly in place. Accordingly, the content(s) may be transported over long distances in a sterile climate-controlled environment, where the temperature can be preset and consistently maintained for much longer duration using a plurality of power sources, e.g. battery pack with one or more rechargeable batteries supplying power for the trip's duration, in essence preserving the transported content's lifespan and viability.
