Honeywell Refrigerant Helps Homeowners Convert The Sun's Heat Into Power
Organic rankine cycle using Honeywell’s 245fa refrigerant turns heat from
solar panels into electricity
MORRIS TOWNSHIP, N.J., Oct. 28, 2009 – Honeywell (NYSE: HON) announced
today that its Genetron® R-245fa refrigerant is being used to help homeowners
generate electricity from the sun’s heat while offsetting energy costs.
Honeywell’s energy-efficient refrigerant is being used in an organic rankine
cycle (ORC) called the 35Z Micro Power Plant, manufactured by Germany-based
Turbolina GmbH & Co. KG. The 35Z Micro Power Plant has a unique design that
uses water heated by thermal solar panels to evaporate the refrigerant, which
in turn drives a turbine to generate electricity. Because no fuel is burned to
create the electricity, the unit does not produce any carbon dioxide emissions.
The remaining heat from the 35Z can be used to supply heating and hot
“When we began designing the 35Z, we knew we needed a reliable, low-temperature
working fluid, and Honeywell’s R-245fa refrigerant was the perfect choice,”
said Hermann Helmbold, General Manager of Turbolina. “The 35Z is a source of
energy that helps homeowners both reduce their carbon emissions and become
independent from traditional sources of energy.”
R-245fa is non-flammable, non-ozone-depleting and has low toxicity. The heat
transfer properties of Honeywell’s R-245fa, including its low boiling point of
59.5 F (15.3 C), makes it ideal for use in ORC systems that use low-temperature
heat and waste heat to generate electricity.
“This unique application is a great example of how Honeywell technologies are
helping homeowners become more energy-efficient,” said David Diggs, global
business director for Honeywell Fluorine Products.
The 35Z offers an electrical power output of 3.5kW, which is ideally suited to
the needs of homeowners. Turbolina specializes in the development, production
and sale of ORC systems that convert low temperature heat into electricity. The
company offers ORC technology in sizes up to 500KW to meet the needs of
differing heat recovery opportunities.
Honeywell is a recognized, leading innovator in advanced energy-efficiency
refrigerants for heating, ventilation and air conditioning, as well as other
heat transfer fluid applications. Honeywell has consistently helped
manufacturers replace ozone-depleting substances and has ongoing research and
development efforts to develop environmentally superior solutions for customers
around the world.
