Summary

THE DEFROSTING CONTROL METHOD MAKING USE OF A TIMER AND A THERMOSTAT CANNOT DISTINGUISH WHETHER THE FROST PHENOMENON CAUSES THE TEMPERATURE OF OUTDOOR HEAT EXCHANGER TO BE LOW OR AMBIENT TEMPERATURE CAUSES THE TEMPERATURE OF OUTDOOR HEAT EXCHANGER TO BE LOW. THEREFORE, TO DISTINGUISH THE REASON OF THE TEMPERATURE DROP OF THE OUTDOOR HEAT EXCHANGER, DEFROST CONTROL BY A DUAL TEMPERATURE SENSOR HAS COME INTO USE RECENTLY. THE FOLLOWING EXAMPLES WHICH ARE NECESSARY TO DESIGN THE DEFROST STARTING CONTROLLER BY A DUAL TEMPERATURE SENSOR ARE DESCRIBED: DESIGN METHOD OF CONTROLLER BY A DUAL TEMPERATURE SENSOR ; MATCHING METHOD TO FIELD RUNNING CONDITIONS.
