The invention discloses an air conditioner control method and an air conditioner, an air inlet of an air conditioner outdoor unit is provided with an air inlet area adjusting device with the adjustable opening degree, and the method comprises the steps that a plurality of outdoor environment temperature ranges are preset, and the starting opening degree of the air inlet area adjusting device is preset for each outdoor environment temperature; and before the compressor is started, the outdoor environment temperature range where the current outdoor environment temperature is located is determined, and the opening degree of the air inlet area adjusting device is adjusted to be the starting opening degree corresponding to the outdoor environment temperature range. The opening degree of the air inlet area adjusting device is adjusted according to the system parameters of the air conditioner, the condensing temperature of the air conditioner during low-temperature refrigeration is increased and is ensured to be within the range of the nominal value of the compressor, and the problems of low condensing temperature, low pressure ratio, serious liquid carrying and poor system reliability during low-temperature refrigeration of the air conditioner are solved. The system pressure stability can be ensured in the starting process of the air conditioning unit, and the problem of starting low-pressure protection is avoided.
Description
Technical field [0001] The present invention relates to the field of air conditioning techniques, and more particularly to a control method and air conditioning of an air conditioner. Background technique [0002] With the gradual impact of global warming, air conditioning is gradually important in human life. With the gradual popularity of air conditioning, the air-conditioning application scenarios have more and more, as air-conditioning is gradually expanded, the temperature adaptability requirements of air conditioners are gradually improved, and the cooling and thermal heat of air conditioning in low temperature environments are also higher. The requirements are first limited to the water vapor in the air, and the heat exchanger is very easy to freeze, resulting in the problem of the reliability of the air conditioner system, high protection, and high failure rate. Inventive content [0003] In order to solve the technical problems of the cooling side temperature excessive ...
