Abstract:
An air conditioning system and a control method therefor, and a control apparatus. The air conditioning system comprises a compressor (1), an indoor heat exchanger (3), an outdoor heat exchanger (2), and an electromagnetic four-way reversing valve (5); the first side and the second side in a valve body of the electromagnetic four-way reversing valve (5) generate a pressure difference capable of enabling the electromagnetic four-way reversing valve (5) to achieve reversing; the air conditioning system is further provided with a gas supplementing portion (6); the gas supplementing portion (6) comprises: a gas supplementing apparatus (61), capable of releasing a gas to the first side and/or the second side, so as to promote reversing of the electromagnetic four-way reversing valve (5) by means of releasing the gas to the same side as a gaseous refrigerant on the basis that the compressor releases the gaseous refrigerant to the first side and/or the second side.
