  • Absorption water heater/chiller and high temperature regenerator therefor
    Patent number: 6470702
    Abstract: An absorption water heater/chiller using lithium bromide as an absorbent and water as a refrigerant, and a high temperature regenerator therefor. The high temperature regenerator is provided with a combustion chamber defined by an inner tube (2) on the side of a blowout port of a burner (4B), from which a combustion gas is blown out. A solution is received in a liquid chamber, which extends on upper and lower sides of the combustion chamber and is defined by an outer tube (1). A refrigerant steam outflow passage (8) is formed in an upper portion of the outer tube, and gas discharge passages (13, 14) are formed at an end portion of the combustion chamber opposed to the burner. A plurality of solution tubes (3) providing communication between the liquid chamber portions on the upper and lower sides of the combustion chamber extend through the combustion chamber.
