Multi-fluid models for highly accurate multiparameter equations of state have been applied very successfully in the past years in order to accurately model thermophysical properties of mixtures. However, the predictive capabilities of this type of mixture

Building stakeholders need practical metrics, data, and tools to support decisions related to sustainable building designs, technologies, standards, and codes. The Engineering Laboratory of the National Institute of Standards and Technology (NIST) has

We investigate refrigerant blends as possible low-GWP (global warming potential) alternatives for R134a in an air-conditioning application. We carried out an exhaustive screening of the binary and ternary blends possible among a list of 10 pure

In previous literature, the uncertainty analyses of experimental results of air conditioners usually ignored the uncertainty due to the equation of state (EoS) of the refrigerants. One possible reason was that the uncertainty reported in the EoS literature

The presentation discusses the application of refrigerants from the beginnings of artificial cold in the era of industrial revolution to the currently used fluids, and the refrigerant options in response to environmental concerns. The outlook for new
A major challenge for future wide area measurement systems is how to efficiently monitor and control the power system, which requires accurate and real-time tracking of the phase, frequency, and Power Factor (PF) of the system. The presence of inter and
The goals of this talk are: 1.) Understand that flammability behavior is device/configuration dependent, and 2.) Understand the features that influence the flammability behavior of a fuel-air mixture.
