Control method and device for refrigeration direct blowing prevention of air conditioner, storage medium and air conditioner

Abstract

The invention discloses a control method and device for refrigeration direct blowing prevention of an air conditioner, a storage medium and the air conditioner. The control method comprises the stepsthat when the air conditioner is in a refrigeration mode and a direct blowing prevention function is started, the coil pipe temperature of an upper evaporator and the coil pipe temperature of a lowerevaporator are detected through an upper coil pipe temperature sensor and a lower coil pipe temperature sensor correspondingly, and the opening degree of a lower electronic expansion valve is adjustedaccording to the upper coil pipe temperature and the lower coil pipe temperature so as to reduce the flow of a refrigerant flowing into the lower evaporator; the current indoor environment temperature is detected through a temperature sensor; and when the difference value between the current indoor environment temperature and the refrigeration set temperature is not larger than a preset temperature threshold value, the opening degree of the lower electronic expansion valve is adjusted through the indoor controller, a lower refrigerant channel is closed, the refrigerant flows into the upper evaporator and the upper air outlet through a liquid distributor, cold air is output, and therefore the direct blowing prevention function is achieved. On the basis of maintaining the indoor temperaturerequirement, cold air is effectively prevented from being directly blown, the indoor temperature is uniform, and therefore comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method, device, computer-readable storage medium and air conditioner for cooling and direct blow prevention of air conditioners. Background technique [0002] At present, some air conditioners on the market have the anti-direct blowing function of cooling. For example, the anti-direct blowing function of some brands of air conditioners is to close the air guide plate of the air conditioner and use the micro holes on the air guide plate to output cold air. , using this method, the air outlet distance of the microholes is very short, and the air volume is relatively small, which will greatly reduce the output cooling capacity of the air conditioner, which cannot meet the requirements of maintaining the room temperature, or the uniformity of the room temperature is very poor, resulting in The comfort is poor. In addition, the anti-blow function of some bra...

In addition, the anti-blow function of some brands of air conditioners is to directly adjust the air deflector of the air conditioner to a small angle to change the air outlet direction of the air conditioner. This method also exists The above problems, and the air conditioner will always output cold air in one direction, which cannot solve the problem of cold air blowing directly on people
