Abstract

In a preferred embodiment, a thermostatically-controlled variable air-circulation mechanism and a thermostatically-controlled coolant-pump circulatable of coolant from a coolant vessel to the fan-containing cooling-coils air-space enclosure cyclically, and a coolant vessel-thermostat and freezing coils connected with an electrical freezer mechanism, are powered by dual batteries in electrical parallel when in use, and the freezer mechanism by solely one thereof when ignition is off for an automobile by virtue of solenoid switch, the fans being run in electrical series at predetermined lower temperatures and in parallel at predetermined higher temperatures by virtue of circuitry and thermostatically-controlled other solenoid switches, maximum ice-production being controlled thermostatically.
