Abstract: A mass and heat exchanger includes at least one first substrate with a surface for supporting a continuous flow of a liquid thereon that either absorbs, desorbs, evaporates or condenses one or more gaseous species from or to a surrounding gas; and at least one second substrate operatively associated with the first substrate. The second substrate includes a surface for supporting the continuous flow of the liquid thereon and is adapted to carry a heat exchange fluid therethrough, wherein heat transfer occurs between the liquid and the heat exchange fluid.

Abstract: The invention relates to a device for controlling the power consumption of one or more electric resistance heating element in a vessel containing a heatable liquid, at least one inlet for receiving a liquid having a first temperature, at least one outlet for removing liquid having a second higher temperature, and at least one thermostat for directing power to at least one heating element. The device has a detector for detecting one or more predetermined conditions in the vessel relating to the amount of liquid having the second higher temperature remaining in the vessel, and for generating an initiating signal corresponding to the predetermined condition. A controller is responsive to the initiating signal, and is configured for outputting a corresponding switching signal. A power modulator is responsive to the switching signal, and is configured for modulating power to at least one heating element.

Abstract: The present invention is directed to a thermal storage system and auxiliary air conditioning systems employing the same, said system employs a heat exchange assembly made from profile board or corrugated board which provides a cost efficient and light weight device for storing an energy storing medium and then using the same at desirable times to provide cooling.

Abstract: A thin plastic-film heat exchanger element for apparatus, such as absorption chillers, is provided, having improved strengthening in the turning regions of the fluid passages, for enhanced resistance to bursting. A method of manufacture, for reduced wrinkling or pleating in the turning regions, is also disclosed.

Abstract: A heat exchange assembly including at least one plate, preferably made from profile board, having a plurality of channels therein for the flow of a heat exchange fluid in a first plane which may be flat or curved and at least one inlet and outlet angled up to 90.degree. with respect to the first plane.
