Abstract:
A co-fired generator for use in a continuous-cycle absorption heating and cooling system may provide heat to the interior of an annulus chamber from a first heat exchanger, such as a firetube heat exchanger, supplemented by heat to the exterior of the annulus chamber from a second heat exchanger containing fluid heated by an external source. Some embodiments may circulate fluid heated in a solar-heated collector through the second heat exchanger. Other embodiments may route exhaust gas from a combustion engine through the second heat exchanger. The second heat exchanger may be provided with a plurality of fins to increase the surface area available for thermal transfer between the heated fluid and the annulus chamber.

Abstract:
The invention contributes to the solution of the problem of polluted atmosphere air by adding an air cleaning function to the closed-type heat pump that can sterilize sanitary water at the same time. The closed-type heat pump is adapted to this end and consists of elements that effectively sterilize and clean the air and sterilize the sanitary water inside the water heater. Sterilization and purification are achieved through the installation of a transparent cone (74) with a UV light bulb (85) inside the upper cap (13) and the mesh filter (84), which is installed around the evaporator (1), lamellar permanent magnets (87) on the funnel cap (76) and multiple fans with motor (75), (79), (80), that ensure an optimal air-flow from the air intake on the upper cap (13) to its exhaust on the lower cap (6). The air is sterilized and purged in the heat pump by means of a UV light bulb (85) and permanent lamellar magnets (87), which give it an electrical charge, so that the smog and dust particles can stick on the mesh filter (84) and evaporator (1). The mesh filter (84) and the evaporator (1) is cleaned by the water by means of a ring with nozzles (4) on the telescopic tube (99), which extends from the top down along the inner water heater mantle (2). If a sterilization of the sanitary water is necessary, the water heater (2) must be transparent. The heat pump works like a sterilizer and an air cleaner, as well as a sanitary water sitter and sanitary water heater. These functions can be performed simultaneously or separately from the heating and cooling function.
