Hydro carbon refrigerant blend and appratus for calculating mass ratio of the same

摘要

A hydrocarbon-based refrigerant mixture of hydrocarbons and a simulation apparatus for calculating a suitable mass ratio are disclosed. Hydrocarbon mixed refrigerant is a mixture of propane (evaporation temperature about -40 ° C at atmospheric pressure), isobutane (-10 ° C ) And butane (0 占 폚).
