Abstract:
A generator for an absorption chiller that uses a burning combustion fluid to heat a solution, comprising:a tube bundle, said tube bundle conveying said solution through a first solution flow path in a heat exchange relationship with said combustion fluid; an inner shell, said inner shell being vertically traversed by said tube bundle and defining a combustion inlet and a combustion outlet, said burning combustion fluid and the combustion products thereof flowing in a single pass from said combustion inlet, across said tube bundle, to and out of said combustion outlet; an outer shell, said outer shell defining a liquid solution outlet and a vapor solution outlet, said outer shell cooperating with said inner shell to define a solution inlet chamber, a solution outlet chamber and a second solution flow path in parallel with said first solution flow path, a first portion of said solution flowing through said liquid solution inlet, through said solution inlet chamber, through said first solution flow path and into said solution outlet chamber and a second portion of said solution flowing through said liquid solution inlet, through said solution inlet chamber, through said second solution path and into said solution outlet chamber; and a distributor in flow communication with said solution inlet chamber, said distributor causing more solution flow through said first solution flow path than through said second solution flow path.
