Meanwhile, the equipment does not have a field test data storage function, and needs to be used for manually recording test data, so that the workload during field use is increased, and the working efficiency is influenced. And no special data storage and management system is provided, so that a manager of the tested equipment can conveniently look up the quality control information of the equipment on line. In addition, the air conditioner is provided with a fan,
