Air conditioner and control method thereof

Abstract

The invention discloses an air conditioner and a control method thereof. The control method of the air conditioner comprises the steps that the target temperature and the current indoor environment temperature are obtained, and the difference value between the current indoor environment temperature and the target temperature is calculated and recorded as the target temperature difference; the target temperature difference is determined to be smaller than or equal to the first preset temperature difference, all indoor heat exchangers conduct heating, and the first preset temperature difference is smaller than 0; and/or the target temperature difference is determined to be greater than or equal to the second preset temperature difference, all the indoor heat exchangers perform refrigeration, and the second preset temperature difference is greater than 0; and/or the target temperature difference is determined to be greater than the first preset temperature difference and less than the second preset temperature difference, and the first indoor heat exchanger, the second indoor heat exchanger and the third indoor heat exchanger are controlled to refrigerate, heat or close according to the value of the target temperature difference, wherein the first preset temperature difference is smaller than 0, and the second preset temperature difference is larger than 0. According to the technical scheme, the adaptability of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] With the improvement of people's living standards, the use of air conditioners has become more and more common, and at the same time, people have also put forward higher demands on air conditioners. Due to the fixed setting of the indoor heat exchanger of the existing air-conditioning indoor unit, the heat exchange area is fixed and cannot be adjusted, so that the temperature range that the air conditioner can adjust during the temperature adjustment process is small, which cannot meet the needs of users. Contents of the invention [0003] The main purpose of the present invention is to provide a control method for an air conditioner, aiming at improving the adaptability of the air conditioner. [0004] In order to achieve the above object, the air conditioner indoor unit proposed by the pr...
