Technical Information. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC New tables of the thermodynamic properties of Freon™ C refrigerant (ASHRAE designation: RC [23/25/52]), a near azeotropic blend of HFC/HFC/ HFCa, have been developed and are presented here. RC. (R /a) (//wt%) Replaces: R Applications: Medium temperature commercial and industrial direct expansion refrigeration and A/C Physical Properties of Refrigerants. Kinematic Viscosity, ft/hr Thermal Conductivity, Btu/(hr·ft·°R) Heat Capacity, Btu/(lb·°R) FreonTM C. Gas Viscosity at Atmospheric Pressure. ̊F) Specific Refrigerant (RC) Transport Properties—Viscosity, Thermal Conductivity, and Heat Capacity for Liquid and Vapor. Since Genetron ® C is a close match to HCFC, it also serves as a retrofit fluid in applications where HCFC is Equations have been developed, based on RC thermodynamic properties (temperature standard)Temperature (°C) Liquid Steam Liquid Steam Liquid Steam Liquid Steam Latent heat Liquid Steam Liquid Steam Physical Properties of Refrigerants. RC. Environmental Classification Molecular Weight Boiling Point (1atm,°F) Critical Pressure (psia) Critical Temperature (°F) Critical Rc is an HFC refrigerant that will replace the Rrefrigerant, as per Montreal Protocol. Environmental Classification Molecular Weight Boiling Point (1 atm, ̊F) Critical Pressure (psia) Critical Temperature (̊F) Critical Density, (lb./ft^ 3) Liquid Density (̊F, lb./ft ^ 3) Vapor Density (bp, lb./ft ^ 3) Heat of Vaporization (bp, BTU/lb.) Specific Heat Liquid (̊F, BTU/lb. FreonTM C. Viscosity, cP C (a ternary blend of HFC/HFC /HFCa, assigned RC by ASHRAE) serves as a non ozone-depleting replacement for HCFC in various air-condi tioning applications, as well as in most refrigeration systems.
