Mayekawa: Industrial refrigeration application and technology trends

An update on industrial refrigeration technology trends and on the impact of regulatory activities on the introduction of natural refrigerants was provided by Eric Delforge of Mayekawa. While ammonia has been historically the most used refrigerant in industrial applications, CO₂ is becoming more popular in negative temperature applications. Hydrocarbons and air are suitable for very low temperature applications. Some of the key technological trends include minimising refrigerant charge through cascade systems or innovative heat exchangers, increased efficiency by means of frequency control, advanced valve control systems or multi-stage systems as well as heat recuperation and improved safety features.
