German installers have evaluated the use of R407C and of CO2 in air/water domestic heat pumps, and concluded that R407C gives a better environmental performance than CO2 - measured as TEWI (Total equivalent Warming Impact).
A newly installed Organic Rankine Cycle (ORC), using a mixture of HFC-134a and HFC-245fa as working fluid, will deliver an additional 2.5 MW to the existing 16.7 MW capacity of a Geothermal Facility in Nevada, USA.
COOL-SAVE is an Intelligent Energy – Europe project, designed to develop and disseminate cost effective strategies to improve energy efficiency in cooling systems in the food and drink sector, the biggest manufacturing sector in the UE.
HFC-134a is used in water chillers necessary for the manufacture of high precision shafts produced in a French factory. This is a technically challenging process, starting from three meters long rods of different diameters which are machined to achieve high precision 6 to 40 mm diameter pieces.
A 16 ton all-electric experimental truck, the world’s largest, is using R404A to provide 6 to 10 KW to keep contained food products between 0 °C and -20 °C.
The US Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has launched Phase Two of its Low GWP Refrigerant Research Project, addressing their use in air conditioning and heat pump systems.
