A conventional air conditioner uses refrigerants, compressors, and heat exchange systems to remove heat from indoor air. Portable personal cooling devices usually focus on improving comfort through airflow and cooling technologies designed for smaller areas.

The BlizzAir Portable AC typically works by drawing warm air into the device, passing it through a cooling mechanism, and releasing cooler air through the outlet. When water-based cooling is used, evaporation can help reduce the temperature of the airflow and create a refreshing cooling effect.
