Refrigerating system, control method thereof, air conditioning equipment, storage device and processor

The invention discloses a refrigerating system, a control method of the refrigerating system and air conditioning equipment using the refrigerating system. The refrigerating system comprises a compressor, a condenser, a throttling device and an evaporator and further comprises a three-inlet and one-outlet gas-liquid mixing separator, a first connector of the three-inlet and one-outlet gas-liquid mixing separator is communicated with an air suction pipeline of the compressor, and a second connector of the three-inlet and one-outlet gas-liquid mixing separator is communicated with an exhaust pipeline of the evaporator. A third interface of the first expansion valve is communicated with a first branch led out between the compressor and the condenser, a fourth interface of the first expansion valve is communicated with a second branch led out between the condenser and the throttling device, and electronic expansion valves are arranged on the first branch and the second branch. The three-inlet and one-outlet gas-l
