Charge models that can predict at what conditions a system will begin to floodback refrigerant to the compressor or operate at excessive superheat, subcooling, ...
The binary mixture of R32/R134a shows a performance improvement of six percent over R22. Since it contains 70 % R134a it may not be flammable. Significant ...
We consider the evolution of refrigerant molecules, the ever-changing constraints and regulations that have driven the need to consider new molecules.
May 29, 2020 ¡¤ This study focuses on energy performance investigation and environmental impact analysis of various new ecofriendly refrigerant blends as alternatives
To predict the fractionation effects when charging HVAC systems from large tanks with non-azeotropic refrigerant blends (such as R407C and Blend "A"), two types ...
