Air conditioner and control method and device thereof

Abstract

The invention discloses an air conditioner and a control method and device thereof. The control method of the air conditioner comprises the steps that in air conditioner action space, the target dressheat resistance, the target metabolic rate and the target mean radiant temperature are obtained; the air temperature and humidity in the space are obtained; according to the target human body thermalcomfort degree evaluation index value, the target dress heat resistance, the target metabolic rate, the target mean radiant temperature and the air temperature and humidity in the space, the air flowrate of the target point in the space is determined; according to the air flow rate of the target point in the space and the current rotation speed of an indoor fan motor, the running state of an airdeflector of an indoor unit is controlled. According to the control method of the air conditioner, the running state of the air deflector of the indoor unit is controlled, the air in a room keeps ina state in which a user keeps feeling comfortable, and therefore, the air conditioner runs in the mode of keeping comfortable and saving energy.

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
