GAS ABSORPTION
HEAT PUMPS
Gas Absorption Heat Pumps combine gas red combustion with a refrigerant interacting with
the environment. The heat pumps are hydronic, thus are used for heating or cooling water.

A
Natural gas or propane red 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 nned coil
(evaporator), indirect contact with the outside air causes
the ammonia to vaporize.
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.

absorption heat pump can be used
for hydronic heating and cooling
applications. The IVS-095-A model is
for heating only, and the IVS-095-AR
is heating/cooling reversible.

OVERVIEW
The air source heat pumps either heat or cool water, and always interact with the outside air, integrating
renewable energy.
HEATING MODE
• Increase the eciency of condensing boiler systems by up to 50%.

(O )
OUTDOORS
• The A or AR heat pumps can heat water up to 140°F.
Systems should be designed to operate the heat
pumps as much as possible as they are the most
ecient component of the heating system.
Outside Wall
INDOORS
• The boilers operate when water temperatures greater
than 140°F are required (up to 240°F), or when the
energy required to heat the building go beyond the
available capacity of the heat pumps.
COOLING MODE
• Satisfy small cooling loads without separate equipment dedicated to cooling.
• Hydronic cooling reduces air duct and fan sizes in a building.

OVERVIEW
Commercial heating and cooling systems can be designed so the water/ground source heat pumps work with boilers,
chillers or other technologies to manage load requirements.
• The W and WLB units simultaneously heat and cool water.
HEATING MODE
To Well Field To Heat Users
Return From Wells Return From Users
• Cold water is directed out to the
well eld.
• Hot water is directed to the heat
users in the building.
COOLING MODE

Return From WellsReturn From Users
• Cold water is directed to the
cooling users in the building.
• Hot water is directed out to the well
eld.
HEATING/COOLING SIMULTANEOUSLY
• Instead of using the well eld, it is possible to use both the hot and cold water for simultaneous applications.
To Cooling Users
Return From Users
Example: Provide space cooling for
areas on the south side of a building;
provide space heating for areas on
the north side of a building.
Example: Provide space heat for a
building in the winter, simultaneously
provide space cooling for a small
load, such as an IT server room.

WELL FIELD REQUIREMENTS
Gas absorption heat pumps require
approximately 40% reduced size
well eld compared to an electric
heat pump system of similar capacity.
This provides substantial savings
in the up front capital investment
associated with this infrastructure.
