Abstract

PURPOSE: To provide a capacity variable compressor, an outside temperature detector and a timer in the operation controllers for refrigerators for preventing the larger frequency of capacity change- over than required, and the shortage of cooling with change-over made to high capacity immediately when temperature does not lower in low-capacity continuous operation.
CONSTITUTION: When outside temperature is higher or lower than a fixed value, an outside temperature detector 4, a relay 6 and a polarity number change contact 6a actuate so that a 2- pole driving contact 6c or a 4-pole driving contact 7a closes to make intermittent 2- or 4-pole operation respectively while controlled by an inside temperature detector 3. When said 4-pole operation is continued for a fixed period of time, a timer coil 5a, a timer contact 5b, a relay coil 6 and a polarity number change-over contact 6a actuate to close and 2-pole driving contact 6b closes and to open said 4-pole driving contact 7a so that change-over is made to 2-pole operation. When outside temperature is changed lower from higher than a fixed value, said outside temperature detector 4 opens to make changeover to 4-pole operation.
