Air conditioner, its control method, and control device

Abstract

The invention discloses an air conditioner and its control method and control device. The air conditioner control method includes: obtaining the target clothing thermal resistance, target metabolic rate and target average radiation temperature in the air conditioner action space; Air temperature and humidity; according to the target human body thermal comfort evaluation index value, the target clothing thermal resistance, the target metabolic rate, the target average radiant temperature, the air temperature and humidity in the space, determine the temperature and humidity in the space. The air flow rate of the target point; according to the air flow rate of the target point in the space and the current speed of the indoor fan motor, the operating state of the air deflector of the indoor unit is controlled. According to the air conditioner control method of the present invention, the operating state of the air deflector of the indoor unit can be controlled to keep the air in the room in a continuous comfortable state, thereby maintaining the continuous comfortable and energy-saving operation of the air conditioner.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner, a control method and a control device thereof. Background technique [0002] In related technologies, the air deflector of the air outlet of the air conditioner is usually set to multiple gears according to the experimental conditions. In actual use, the angle is automatically adjusted according to the set angle, or the user adjusts the air deflector according to his own needs. angle. However, there are obvious deficiencies in the above-mentioned control method of the angle of the air deflector: on the one hand, the multiple gear angles set in the laboratory cannot well cover the air supply requirements of the user in real use; on the other hand When the user adjusts the air deflector, the main consideration is that he feels uncomfortable, but the user does not know how to adjust it properly, so he often adjusts the angle of the air deflector to the ...

Problems solved by technology

However, there are obvious deficiencies in the above-mentioned control method of the angle of the air deflector: on the one hand, the multiple gear angles set in the laboratory cannot well cover the air supply requirements of the user in real use; on the other hand When the user adjusts the air deflector, the main consideration is that he feels uncomfortable, but the user does not know how to adjust it properly, so he often adjusts the angle of the air deflector to the minimum air outlet position, resulting in a too low wind speed that is not conducive to the replacement of the air conditioner. Thermal effect, resulting in poor cooling effect, high energy consumption, high electricity bills, etc., and it cannot improve the user's comfort very well, and requires the user to manually adjust back and forth, which also increases the user's burden
