A
Natural gas or propane fired combustion heats up the
refrigerant solution contained in a chamber (generator).
The heat from combustion separates the ammonia and
water in the solution.
B
Heat is transferred to the hydronic loop as a result
of indirect contact with hot vaporized ammonia. The
ammonia changes phase from a vapor to a liquid as this
happens (condenses).
C
As the liquid ammonia travels through the finned coil
(evaporator), indirect contact with the outside air causes
the ammonia to vaporize.

TRADITIONAL GAS FIRED COMBUSTION
AMMONIA ABSORPTION PROCESS
Gas Absorption Heat Pumps combine gas fired combustion with a refrigerant interacting with
the environment. The heat pumps are hydronic, thus are used for heating or cooling water.
D
Water is introduced to vaporized ammonia, resulting
in a natural heat-producing exothermic reaction inside
a chamber (re-generator). This is where we obtain free
and renewable energy as a result of interacting with the
environment.
E
Heat is transferred to the hydronic loop as a result of
indirect contact hot water-ammonia solution created in
the re-generator.
F
A small pump moves the solution back to the
generator so the cycle can continue.
