Absorption (Gas-Fired) Heat
Pumps
Absorption heat pumps (or gas-fired heat
pumps) are a new type of heat pumps in the house, commercial and
industrial market. The
big difference between these heat pumps and the common ones is
in their energy sources.
Energy sources
Absorption heat pumps are air-source heat pumps driven by
natural gas, propane or even solar-heated water or
geothermal-heated water. Sometimes they are referred as
gas-fired heat pumps (gas is their most common heat source).
Absorption heat pumps technology is recent
and yet rather experimental. Some
important manufacturers (Sanyo…) are beginning to bet on this
type of equipment, but their offer is still rather restrict to
commercial buildings.
Gas fired models
Most absorption heat pumps have gas and LPG
(Liquefied Petroleum Gas) as their power source.
An environmental option
Due to their power sources, these pumps
constitute a valid environmental option. They can make use of solar energy and geothermal hot
water; even gas fired models may reduce CO2 and NOX emissions relatively to
electricity driven models.
