The invention discloses a variable frequency air conditioning system with a driving module adopting liquid cooling heat dissipation, which comprises a variable frequency compressor, a four-way valve, an outer heat exchanger, an inner heat exchanger, a gas-liquid separator, a driving radiator and a refrigerant flow direction automatic diversion assembly, the refrigerant flow direction automatic diversion assembly is formed by connecting a first one-way valve, a second one-way valve, a third one-way valve and a fourth one-way valve in series and in parallel, and the input end of the first one-way valve and the output end of the fourth one-way valve are connected in parallel and then connected to an outer heat exchanger serving as a condenser in a refrigeration mode. A high-pressure liquid refrigerant output by the outer heat exchanger passes through the first one-way valve and then enters the driving radiator; the output end of the driving radiator is also connected with a main path first expansion valve for co
