ABSTRACT:
This invention discloses an extremely simple chemical heat pump system, utilizing the chemical reaction heat of a perfectly reversible chemical disassociation reaction system, wherein one gaseous compound is involved in said reversible reaction. The present system can realize a large coefficient of performance over a very attractive temperature range and level for general use, by absence of any phase transition. Reaction kinetics of said system is excellent since only one reversible non-flammable gaseous compound is involved in said chemical heat pump system. Said system can be provided with a computer controlled system for changing the restriction value of the expansion valve. The said system is superior to most conventional compression system by replacing the use of ozone (layer) attacking C.F.C's (chlorofluorocarbons) over the entire temperature range.
