Abstract: The present invention involves a retrofit lighting assembly for use with conventional lighting assemblies. The retrofit lighting assembly includes a base configured to engage the conventional lighting assembly socket, and a bracket assembly coupled to the base. The bracket is expandable so that once the base is secured inside the lighting assembly housing it may expand for attachment to the housing.

Abstract: A ventilating system for adjusting temperature within acoustic enclosures for combustion turbines and other engines. The ventilating system includes a duct in flow communication with an inlet opening of the acoustic enclosure. A heat exchanger connected to a source of coolant, such as an absorption refrigeration system, is installed in the ventilating duct and changes the temperature of air passing through the ventilating duct. A blower causes air within the ventilating duct to pass over the heat exchanger and then into the enclosure through its inlet opening. As the air continues to pass through the enclosure and out of an enclosure outlet opening, the temperature within the enclosure around the engine is adjusted.

Abstract: A thermal energy storage system is operable in heating capacity storage and discharge modes and cooling capacity storage and discharge modes for maintaining a temperature in a vehicle compartment. Each mode includes a thermal charging cycle and a thermal discharging cycle. The thermal energy storage system communicates with a vehicle air conditioning system including a compressor and a vehicle coolant system including a vehicle engine. The thermal energy storage system comprises a thermal storage apparatus housing thermal energy storage material that stores thermal energy. The thermal storage apparatus is connected to the air conditioning system and the coolant system so that a refrigerant or coolant flows through the thermal storage apparatus in heat transfer relationship with the thermal energy storage material.

Abstract: A vapor compression refrigeration system for providing cold storing which; during a conventional cycle provides cooling to an indoor heat exchanger in the conventional fashion, during a cooling charging cycle refrigeration effect is stored in a heat storage vessel by refrigerant evaporation with the indoor heat exchanger being by-passed and during a discharging cooling cycle refrigerant passes through the heat storage vessel without evaporation and evaporates in the indoor heat exchanger to provide space cooling.

Abstract: An encapsulation apparatus is provided for a thermal management system for at least one battery. The apparatus comprises a housing including an inner wall defining a receptacle for the battery. The inner wall is positioned in thermal contact with the battery. The housing further comprises an outer wall in spaced-apart relationship with the inner wall to define an enclosure therebetween for receiving a phase change material.

Abstract: A heat exchanger for a phase change material is provided which comprises a container holding the phase change material, a tube surrounding the container to define an annular space therebetween, and at least two divider walls extending across the annular space to divide the annular space into at least upper and lower flow passageways. The heat exchanger can preferably be operated in either a melt cycle or a freeze cycle. In the melt cycle, the lower flow passageway is configured to receive heat exchange fluid to initiate melting of the phase change material from the bottom so that newly-formed liquid phase change material is displaced toward the top of the container. In the freeze cycle, the upper flow passageway receives heat exchange fluid to initiate freezing of the phase change material at the top. The newly-formed solid phase change material falls to the bottom of the container, displacing liquid phase change material toward the top.
