Start discharging the charge through 19 for a predetermined time (about 3 minutes)
During this period, the output of the comparator (to) is cut off. Therefore, even if the ON signal voltage is applied from the thermo circuit (I9) during this predetermined time, the ON signal voltage is not output from the OFF circuits 0 to 0, and the compressor is not driven.In this way, the refrigerant pressure difference This prevents the compressor a from locking due to startup when the voltage is large. At the same time, the capacitor (4) of the ON circuit (c) is charged with electric charge.
