Abstract:
1. A method for operating a refrigeration device, the device provided with two separate temperature zones each having a set temperature range, each cooled by a separate evaporator with both evaporators arranged in a common coolant circuit having operational and non-operational phases, a first one of the temperature zones including a fan, comprising: sensing the temperature in at least a first one of the temperature zones; sensing the ambient temperature of the refrigeration device; intermittently operating the fan in operational and non-operational phases depending on a preset temperature sensed in said first temperature zone to maintain each of the separate temperature zones in their respective set temperature range controlling the operational and non-operational phases of the fan and the coolant circuit such that the operational phases of said coolant circuit coincide at least partially with the non-operational phases of said fan; and controlling the proportion of the operating time of the refrigeration device in which said fan and said coolant circuit are simultaneously operational depending upon said sensed ambient temperature of said refrigeration device.
