There is nothing more difficult than delivering fresh fish to the table. It's time for freezing. Let's add a new refrigerant and establish a transport system below the ambient temperature. We need a new refrigerant that lowers the temperature of the fluid by electricity, don't we? The fish we catch will die soon. Refrigeration, freezing!

This is a proposal for a new refrigerant that consumes electricity and lowers the temperature of the fluid below the ambient temperature.
