CFC-free chemisorption heat pumps and refrigeration.

Author(s) : RYAN W. A.


The article explains the principle and operation of a cold-production chemical adsorption system. The affinity of some ammonia salts for ammonia is used. This type of salt "sucks" ammonia from a evaporator. At saturation, this salt is regenerated by heat; ammonia is released under pressure and is condensed and then expanded in the evaporator. Possible applications of the process are evoked, along with its performances. The advantages of the system are listed, along with expected developments.
