Abstract
An ice-lined vaccine refrigerator includes a vaccine storage compartment, an electrically powered cooling circuit, the electrically powered cooling circuit being configured to generate an ice-lining and to cool the vaccine storage compartment; an AC power inlet adapted for connection to an external supply of AC power; and a refrigerant compressor forming part of the electrically powered cooling circuit and adapted to be powered by the external supply of AC power through the AC power inlet. Reliability is improved by using a DC powered compressor and an AC/DC convertor to convert AC power received at the AC power inlet to DC power to power the compressor.
