Abstract
An electric motorfor driving a compressorthat composes a refrigerating cycle is speed-controlled by an inverter circuit. When an inside temperature Tx detected by an inside temperature sensoris not less than a predetermined temperature (for example, 5° C. in the case of a refrigerator and −18 C in the case of a freezer), a microcomputersuppresses the rotational speed of the electric motorvia the inverter circuitto thereby restrict current flowing through the electric motorand a power circuit. Accordingly, great current does not flow through the electric motorupon the start of the operation in a refrigerator or a freezer. Further, in this case, the rotational speed of the electric motoris controlled to be increased as the inside temperature Tx becomes lower, whereby the cooling speed of the insideis increased with the current flowing through the electric motorprevented from increasing.
