摘要

A mathematical model of the evaporator of a heat pump with carbon dioxide as a working medium and water as a heat-transfer medium is constructed and used to calculate the hydrodynamic and heat- and mass-transfer processes in boiling liquid convection, liquid film evaporation, film breakup, drop settling, and disperse flow. The coupled heat transfer between the working medium and the heat-transfer medium in a countercurrent evaporator is considered. The calculation results are compared with the experimental data.
