An absorption heat pump achieves improved efficiency by lowering the low cycle temperature of the circulation fluid. This is accomplished by adding a crystallization-inhibiting compound to the circulation fluid which substantially depresses the temperature at which the absorbent salt in the fluid begins to crystallize.
