WORKING SUBSTANCES FOR ABSORPTION MACHINES

摘要

A lye or a mixture of two or more lyes is added to the working substance system of absorption machines which work with ammonia or methylamine as working substance and with water as solvent. The admixture of lye or a lye mixture to the water has a series of advantageous effects, such as (1) the reduction of the dissolution or expulsion heat of the working substances, so that the performance number is increased; (2) a high degree of purity of the generated working substance steam, so that a dephlegmator may be dispensed with; (3) steel surfaces are rendered inert by the lye in the absence of air in a high vacuum, so that corrosion inhibitors may be dispensed with; (4) the viscosity of the solvent is diminished, so that the work of the pump is reduced.
