Low-GWP Refrigerants: The Importance of the Thermophysical Properties for HVAC Design

Novel refrigerants with short atmospheric lifetime are being investigated to replace previous generations of working fluids in refrigeration, air-conditioning, and heat pump systems. To promote the transition, a thorough evaluation of refrigerant suitability and performance is needed, by means of a sound knowledge of their thermophysical properties. In this thesis, key properties of low-GWP refrigerants retrieved from the public literature are examined, based on which an assessment is developed on the reliability of reference property prediction models for the HVAC design software.
