January 8, 2019—Technicians can access a free tool developed by Oak Ridge National Laboratory to support the installation and repair of heating, ventilation and air conditioning systems, particularly when using new refrigerants. Researchers at ORNL have launched a mobile app called fProps to quickly check fluid properties such as refrigerant, coolant and air while installing or repairing HVAC equipment in commercial and residential buildings. Users specify inputs for each property and a wizard then guides through the module within the tool. “With fProps, technicians have at their fingertips a way to evaluate air, coolant, refrigerants and capacity calculation functions,” said ORNL’s Bo Shen. “This tool also provides additional support for professionals using new low global warming potential refrigerants in HVAC systems.” The fProps app is a pilot program, and additional modules can be added in the future based on interest.
