Electricity Produced by Refrigerant?

Honeywell has announced that a refrigerant it markets as Genetron 245fa is helping to produce energy-efficient electricity at an aquatic complex in Lausanne, Switzerland.

The refrigerant is being used in an organic Rankine cycle (ORC), which generates electricity from waste heat.

According to a published report from Honeywell, the ORC is part of a micro-cogeneration system, manufactured by Eneftech Innovation, which generates electricity while simultaneously heating the swimming pools at the Mon-Repos complex.

The waste heat is fed into the ORC system, which evaporates the refrigerant in a closed system. The evaporated refrigerant then drives a turbine to generate electricity. Because no fuel is burned to create the electricity, the ORC unit does not produce any carbon dioxide emissions.

“We needed a refrigerant to run our system and selected Genetron 245fa because of its unique combination of desirable attributes: high cycle efficiency and nonflammability,” said Antonio Mendes Nazare, vice president, Eneftech. “Our ORC technology uses highly effective scroll expanders to generate 15kW for this project. Genetron 245fa is the perfect choice for a working fluid to run our system.”

“This is another example of Honeywell technology helping to make alternative, cleaner energy sources a reality,” said Andrew Brown, marketing manager for Honeywell’s Fluorine Products business. “We’re helping our customers provide safe, environmentally-compliant, and energy-efficient solutions.”

Eneftech, based in Switzerland, markets new, sustainable energy technologies to supply combined heat and electricity using renewable energy sources such as biomass, solar thermal, and geothermal, as well as other heat sources such as boilers, exhaust gases, and industrial waste heat. Eneftech develops patented microturbine systems, based on the ORC.
