Abstract

A cooler device (1) adapted to operate with the method according to the present invention comprises at least one cooler compartment (10) and at least one freezer compartment (11); temperature sensors (13, 14) situated in said compartments (10, 11) to measure the temperature in said compartments (10, 11); a cooling setup containing evaporator (2), condenser (9), compressor (5) units, at least one fan (3), circulating air cooled down by the evaporator (2) within the cooler device (1), and at least one damper (4) that is opened and closed in an airflow channel (6) between the compartments (10, 11); and a control unit (12) controlling the operation of the cooler device. According to this method, temperatures measured (TF, TR) are compared to predetermined threshold values (TF1, TF2, TR1, TR2) in the control unit (12) and the operation states of the compressor (5) and fan (3) and the open/closed position of the damper (4) are determined according to the result of such comparisons.
