Cool Phill - the table-top household appliance that:

1.    Cools glasses and drinks in glasses

2.    Displays a glass with a chilled beverage

3.    Offers toasts for different kinds of meetings

The KF can run on battery if is not used about for a short time, for example, at a weekly meeting of friends.
But also the KF can be turned on to the normal electrical network. This is convenient if the KF operates daily for many hours, for example, at a hotel counter, in a bar, etc.

If the CF must work more than 5 hours in a row, then you need to have a minimum of 2 sets of refrigerants. When the temperature of the working refrigerants rises, they change.

Fresh refrigerants from the freezer compartment are inserted into the CF, and spent refrigerants are laid in the freezer.
