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.

Abstract: An ice-lined cold storage device (10) comprising: a cold storage compartment (15) arranged at an interior of the ice-lined cold storage device; an ice-lining (25a, 25b, 25c, 25d) configured to absorb heat from the interior of the cold-storage device; a cooling circuit (16) configured, when in operation, to remove heat from the ice-lining; an inner liner (22) arranged between the cold storage compartment and the ice-lining, the inner liner comprising a sheet material (23) having a major surface which faces towards the cold storage compartment and a major surface (27) which faces towards the ice-lining; is provided with an electrical heating element (26) arranged at one of the said major surfaces of the inner to provide heat to the interior of the cold storage device.
