Problems solved by technology

However, the existing air conditioners do not take into account the influence of the outdoor ambient temperature when performing frequency reduction control. Under the condition of different temperature differences between the outdoor ambient temperature and the indoor ambient temperature, when the same set temperature is reached, the compressor will not be able to cool or heat. The power consumption is different, therefore, it is necessary to provide a power reduction control method combined with the outdoor ambient temperature

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to an air conditioner control method and an air conditioner. The control method comprises the steps that the indoor environment temperature T < inner >, the outdoor environment temperature T < outer > and the user set temperature T < set > are obtained; the difference value delta T1 between the indoor environment temperature T < inside > and the user set temperature T < set > and the difference value delta T2 between the indoor environment temperature T < inside > and the outdoor environment temperature T < outside > are calculated, delta T1 = T < inside >-T < set >, and delta T2 = T < outside >-T < inside >; according to the difference value delta T1 and the difference value delta T2, whether power reduction control is carried out or not is determined; and when power reduction control needs to be carried out, the frequency of the compressor and the rotating speed of the outer fan after power reduction operation of the air conditioner are determined according to the difference value delta T1 and the difference value delta T2. According to the control method and the air conditioner, during power reduction operation, the outdoor environment temperature, the indoor environment temperature and the set temperature are combined to determine the frequency of the compressor and the rotating speed of the outer draught fan after power reduction operation, and therefore energy consumption is effectively saved on the premise that the comfort experience of a user is guaranteed.

Description

technical field [0001] The invention belongs to the field of air conditioners, in particular to an air conditioner control method and the air conditioner. Background technique [0002] Existing inverter air conditioners often perform power reduction control when the indoor ambient temperature reaches a set temperature, such as reducing the frequency of the compressor. However, the existing air conditioners do not take into account the influence of the outdoor ambient temperature when performing frequency reduction control. Under the condition of different temperature differences between the outdoor ambient temperature and the indoor ambient temperature, when the same set temperature is reached, the compressor will not be cooled or heated. The power consumption is different, therefore, it is necessary to provide a power reduction control method combined with the outdoor ambient temperature. [0003] In view of this, the present invention is proposed. Contents of the invent...
