Abstract

PURPOSE: To prevent refrigerant from freezing a compressor by switching the energization of a crankcase heater to a battery at commercial power interrupting time to always energize the heater from the battery when a compressr motor is stopped.
CONSTITUTION: Compressor motor 5, crankcase heater 4 and batery 9 are connected through contacts 10, 11 and 12, respectively to a power switch 8. The heater 4 and the battery 9 are connected through contacts 13. The contacts 10 and 12 are normally colsed, while the contacts 11 and 13 are normally open. Accordingly, if the switch 8, is poened or if the commercial power is interrupted before the switch 8, a relay 14 is deenergized to open the contacts 12 and to close the contacts 13 to thereby continuously energize the heater 4 from the batrery 9
