Shunt compensation control system of inverter-driven multi-split air conditioner

The invention provides a shunt compensation control system of an inverter-driven multi-split air conditioner. In the invention, the inlet, middle and outlet of an evaporator of each indoor unit are respectively provided with a temperature sensor, vapor temperature at the inlet, middle and outlet of the evaporator is detected, and detection data is transmitted into a control computer; the control computer carries out comparative analysis to obtain a valve-regulating flow value required for each indoor unit and transmits the valve-regulating flow value to an electronic expansion valve in a command mode; and the electronic expansion valve receives the command and throttles vapor flowing through the electronic expansion valve, and the throttled vapor enters into the corresponding evaporator to exchange heat with internal environment, then is converged by a gas-liquid separator and is absorbed into a compressor, thus the purpose that the flow of the individual evaporator is matched with the indoor unit loading cap
