AIR CONDITIONER DEFROST OPERATION CONTROL METHOD PREVENTING SUDDEN CHANGE OF ROOM TEMPERATURE

摘要

PURPOSE: A defrost operation control method of an air conditioner is provided to prevent room temperature from being suddenly changed by quickly controlling rotations of a supply fan and an exhaust fan of a ventilation system by performing a preliminary defrost operation in advance. CONSTITUTION: A defrost operation control method of an air conditioner is composed of steps for interlocking and operating the air conditioner and a ventilation system(S10); transmitting a defrost preliminary signal from the air conditioner to the ventilation system before the predetermined time of a defrost operation(S30); dropping and operating the air flow of supply and exhaust fans for ventilation if the defrost preliminary signal is transmitted(S50); sending a defrost signal from the air conditioner to the ventilation system(S110); and stopping immediately the supply and exhaust fans if sending the defrost signal and defrost-operating the air conditioner(S120,S130).
