Embodiment Construction
[0017] In order to make the embodiments of the present invention, the technical solutions of the present invention will be apparent from the accompanying drawings, which will be described in connection with the accompanying drawings, and the embodiments are intended to be described in connection with the accompanying drawings. Embodiment. Those skilled in the art will appreciate that these embodiments are intended to illustrate the technical principles of the present invention, and are not intended to limit the scope of the invention.
[0018] The air conditioner defrosting control method of the present invention is that after the air conditioner enters the defrost mode, the time control of the outdoor fan inversion time T is controlled every set time. The time t is determined as follows: detects the temperature of the outer coil temperature and the external ambient temperature; determines the time T according to the outer coil temperature and the external ambient temperature. For...

The invention belongs to the technical field of air conditioners, and in particular relates to a defrosting control method for an air conditioner. In order to improve the defrosting efficiency of the air conditioner, the method proposed by the present invention includes the following steps: after the air conditioner enters the defrosting mode, control the reversal time T of the outdoor fan every set time; wherein, the time T is determined as follows: Coil temperature and outer ambient temperature; the time T is determined according to the outer coil temperature and the outer ambient temperature. The invention controls the fan reversal time T every defrosting period of time, that is, after each part of the frost is melted, the frost layer is quickly blown off by the back-blowing effect of the outdoor fan, thereby improving the defrosting efficiency. In addition, the time T is determined according to the temperature of the outer coil and the temperature of the outer environment, that is, the reversal time of the outdoor fan is controlled by the double standards of the temperature of the outer coil and the outer environment, so as to control the time of each reversal of the fan more accurately, and improve the efficiency of the operation. Accurately and efficiently blow off the melted frost layer, greatly improving the defrosting efficiency of the air conditioner.
Description
Technical field [0001] The present invention belongs to the technical field of air conditioners, and more particularly to an air conditioner defrosting control method. Background technique [0002] The air conditioner is an apparatus capable of adjusting the indoor ambient temperature, and its working principle is to reduce or increase the indoor ambient temperature through high pressure / low pressure / gaseous / liquid state transition between the refrigerant through high pressure / low pressure / gaseous / liquid state. From the perspective of an indoor unit, the air conditioner is in a cooling or heating condition. When the air conditioner is hot, if the outdoor outer coil temperature will result in frosting, the outdoor electric vehicle cream will result in a reduced heat exchange efficiency of the outdoor heat exchanger, affect the air conditioner Thermal effects reduce the comfort of the indoor environment, affecting the user experience. Therefore, in the case where the ai...
