Abstract

The rate of water vapor sorption of an absorption cycle cooling and/or heating system using an aqueous alkali metal halide or hydroxide solution as the working fluid is increased by adding to the fluid an effective additive amount of at least 2 parts per million of a primary, secondary or tertiary aliphatic, cycloaliphatic, heterocyclic or aromatic amine to the fluid capable of increasing the rate of water vapor absorption.
