Systems and methods to minimize heat transfer additive decomposition in an absorption chiller generator

摘要

A method and system for removing a heat-transfer additive from an absorbent and a refrigerant. An absorber (10) is provided in which a fluid containing absorbent and heat-transfer additive absorbs refrigerant vapor to form a weak fluid containing absorbent, refrigerant and heat transfer additive. A centrifugal separator (20) separates the weak fluid into a heat transfer additive depleted fluid and a heat transfer additive enriched fluid. The heat transfer additive enriched fluid is fed to the absorber (10) and the heat transfer additive depleted fluid is fed to one or more generators (28). The one or more generators (28) evaporate the refrigerant to form a strong fluid and condense the evaporated refrigerant to form a refrigerant liquid. An evaporator (46) is provided for heating the refrigerant liquid to cool a coolant and form a refrigerant vapor.
