Document Type and Number:
Japanese Patent JP2002544462
Kind Code:
A
Abstract:
An absorption chiller wherein refrigerant such as water is dissolved in liquid absorbent such as lithium bromide to form a solution of refrigerant in the absorbent. The absorption chiller includes a generator 4 to boil-off the water refrigerant from the lithium bromide absorbent to separate the water as stream from the lithium bromide. The generator 4 comprises an upper tank 42 and a lower tank 36 interconnected by plain heat exchange tubes 38A and finned heat exchange tubes 38B. Two thermo-syphon tubes 58A and 58B also interconnect and open into each of the tanks containing the aforesaid solution which flows from the upper tank 42 through the tubes 58A, 58B to the lower tank 36 and from the lower tank to the upper tank through the heat exchange tubes 38A, 38B wherein aforesaid boil-off takes place. The heat exchange tubes are disposed in cross-flow relation to hot heating gases or products of combustion flowing in direction X through a combustion chamber 46, from a fuel gas pre-mix package burner 50, the heat exchange tubes being in said combustion chamber. Heat insulation material separates the thermo-syphon tubes from the combustion chamber. Steam leaves the upper tank through an outlet 72 and concentrated lithium bromide through an outlet 70. The weak solution of lithium bromide is introduced into the upper tank through an inlet opposite the upper end of thermo-syphon tube 58A.
