Transport properties measurement on low GWP alternative refrigerants [PDF]
AIP Conference Proceedings, 2017 New experimental data on the thermal conductivity and the viscosity of low-GWP refrigerants such as HFOs are reported in order to contribute to the development of low-GWP refrigeration/heat pump systems. Accurate data on thermodynamic and transport properties are indispensable to design and to manufacture the systems with high efficiency.

Thermal Conductivity of Low-GWP Refrigerants Modeling with Multi-Object Optimization
Algorithms, 2022 In this paper, the procedure of finding the coefficients of an equation to describe the thermal conductivity of refrigerants low in global warming potential (GWP) is transformed into a multi-objective optimization problem by constructing a multi ...

Thermal Performance Analysis of Low-GWP Refrigerants in Automotive Air-Conditioning System
Advances in Materials Science and Engineering, 2020 The energy and exergy of low-global warming potential (GWP) refrigerants were investigated experimentally and theoretically. Refrigerants with a modest GWP100 of ≤ 150 can be sufficient for bringing down emissions which were concerned for the automotive

Controlling quantum state transfer in spin chain with the confined field
, 2005 As a demonstration of the spectrum-parity matching condition (SPMC) for quantum state transfer, we investigate the propagation of single-magnon state in the Heisenberg chain in the confined external tangent magnetic field analytically and numerically. It
