The invention relates to the field of household appliances and discloses an air conditioner control system. The air conditioner control system comprises a power supply module and a plurality of electromagnetic valves, wherein the power supply module is connected with a single chip and a display module; a plurality of temperature sensors are connected with the single chip; a plurality of output power supplies are connected outside the single chip; the plurality of output power supplies are connected with the plurality of electromagnetic valves; and the plurality of electromagnetic valves are respectively mounted on a pipeline of an air conditioner and a thermal circulating system of an engine. According to the air conditioner control system, as the single chip is utilized to sense the plurality of temperature sensors and control the plurality of output power supplies, the plurality of output power supplies can control the plurality of electromagnetic valves; and as the plurality of electromagnetic valves are respectively mounted on LNG pipeline and the thermal circulation system of the engine, the LNG air conditioner is controlled, the effect of the LNG is brought into full play and an energy-saving and environmental protection purpose is achieved.
