Thermal conductivity of liquid refrigerant R404A

Thermal conductivity of liquid refrigerant R404A Abstract Thermal conductivity of liquid ozone-safe refrigerant R404A was studied for the first time in the range of temperatures of 297.9–332.6 K and pressures from the saturation line to 3.7 MPa. The uncertainties of temperature, pressure, and thermal conductivity measurements were estimated to be within ±0.1 K, ±3 kPa, and ±0.15%, correspondingly. Values of thermal conductivity were calculated for liquid R404A at the boiling line. Approximating dependences for thermal conductivity were obtained for the whole range of studied temperatures and pressures, and at the boiling line. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Thermal conductivity of liquid ozone-safe refrigerant R404A was studied for the first time in the range of temperatures of 297.9–332.6 K and pressures from the saturation line to 3.7 MPa. The uncertainties of temperature, pressure, and thermal conductivity measurements were estimated to be within ±0.1 K, ±3 kPa, and ±0.15%, correspondingly. Values of thermal conductivity were calculated for liquid R404A at the boiling line. Approximating dependences for thermal conductivity were obtained for the whole range of studied temperatures and pressures, and at the boiling line.
