Abstract: A condensing heat exchange economizer wherein upwardly flowing hot flue gas is redirected to flow in a downward direction over a bundle of heat exchange tubes carrying a counter-flowing heat exchange medium to form condensate and cool the flue gas, and the condensate is forced by gravity to flow in the downward direction. The economizer may be in the form of a cylindrical economizer adapted for insertion in an exhaust stack for flue gas. The cooled flue gas may be redirected to flow in an upward direction and merged with a primary flow passage leading to the stack.

Abstract: An air conditioning system for conditioning the space within an enclosure having at least one inlet and one outlet, the system comprising first and second liquid/air heat exchangers; the first heat exchanger having an opening for receiving fresh air from the environment and for propelling the fresh air through the first heat exchanger to exchange heat with the liquid before it is entered into the enclosure, and the second heat exchanger having an opening for receiving air from the enclosure and for propelling it through the second heat exchanger to exchange heat with the liquid before it is expelled into the atmosphere. There are also provided methods for air-conditioning an enclosed space and for evaporation of industrial wastes.

Abstract: A liquid desiccant regenerator system, including a desiccant/air heat exchanger having a first desiccant inlet and a desiccant reservoir. The reservoir has a first desiccant outlet, a second desiccant outlet and a second desiccant inlet. The first desiccant inlet and the first desiccant outlet are connectable to a heat source, the second desiccant inlet conducts diluted desiccant of the reservoir and the second desiccant outlet conducts concentrated desiccant from the reservoir. The second desiccant inlet and the desiccant outlet are connected to a desiccant/desiccant heat exchanger for applying heat to the diluted desiccant flowing into the reservoir. A dehumidification method is also provided.
