Abstract

Refrigeration appliance comprising a zero-degree (0°C) compartment, temperature of which is controllable by adjusting fan rotation speed with respect to evaporator surface temperature. More particularly it relates to a refrigeration appliance (1) comprising a storage cabin (2), a compressor, a condenser, a tube expander and an evaporator such that cooling of said storage cabin (2) is effectuated by circulation of a refrigerant through said compressor, condenser, tube expander and evaporator, said refrigeration appliance (1) further comprising a zero-degree compartment (4) and an evaporator fan in said storage cabin (2). The operation of the evaporator fan is delayed during OFF cycle of the compressor.
