In order to evaluate the heat transfer characteristics of nanorefrigerant and the cycle behavior of nanoparticles in the refrigeration system, the migration of nanoparticles during pool boiling was investigated experimentally. Weigh method is used in the present study. The research focuses on the influence of nanoparticle type and size, refrigerant type, mass fraction of lubricating oil, heat flux and initial liquid-level height on the migration of nanoparticles during pool boiling. The experimental results show that the migration ratio of nanoparticles during the pool boiling of refrigerant-based nanofluid increases with the decrease of nanoparticle density, nanoparticle size, dynamic viscosity of refrigerant, mass fraction of lubricating oil or heat flux; while increases with the increase of liquid-phase density of refrigerant or initial liquid-level height.
