Abstract

The invention discloses a control method of an air conditioner and an air conditioner. The air conditioner comprises an indoor unit and an outdoor unit, wherein the outdoor unit comprises an outdoor fan and an outdoor heat exchanger. The control method comprises the steps of when the air conditioner enters the heating mode, judging whether the heating time of the air conditioner reaches the first preset time or not; if the heating time of the air conditioner reaches the first preset time, continuously detecting the temperature of the outdoor heat exchanger, and when the heating time reaches the second preset time, recording the minimum temperature of the outdoor heat exchanger; when the heating time reaches the second preset time+(preset time interval *N), detecting the current temperature of the outdoor heat exchanger; judging whether the difference value of the minimum temperature of the outdoor heat exchanger and the current temperature is smaller than the preset temperature difference or not; and if the difference value of the minimum temperature of the outdoor heat exchanger and the current temperature is larger than the preset temperature difference, increasing the current rotation speed of the outdoor fan by the preset rotation speed till the current rotation speed of the outdoor fan reaches the target rotation speed. According to the control method of the air conditioner provided by the embodiment of the invention, the outdoor heat exchange effect can be improved, and the heating effect during low temperature can be improved.

Description

technical field [0001] The invention relates to the field of air conditioner control, in particular to an air conditioner control method and the air conditioner. Background technique [0002] Air conditioners, such as heat pump air conditioners, obtain heat from the outdoor air to cool the outdoor air when heating, and form condensed water on the outdoor heat exchanger. If the outdoor condensed water is discharged, a water bridge is formed between the fins of the outdoor heat exchanger, which will cause As a result, the wind resistance of the outdoor air duct becomes larger, the air volume becomes smaller, the heat transfer deteriorates, and frost builds up on the outdoor unit, affecting the heating experience. Related technologies have considered hydrophilic materials, fin shapes and fin spacing, and to a certain extent slowed down the frosting speed of heat pump heating, but the cost of materials is too high. [0003] In the related art, the air volume control process of ...
