Problems solved by technology

[0004] After the air conditioner stops running, the indoor space continues to exchange heat with the outside world, causing the temperature difference between the actual indoor temperature and the set indoor temperature to exceed the dead zone temperature range, that is, the indoor temperature fluctuates, and the temperature fluctuation will cause the air conditioner to continue to operate , and when the temperature difference between the actual indoor temperature and the set indoor temperature enters the dead zone temperature range again, the air conditioner stops running again, so that the air conditioner starts and stops repeatedly, accompanied by fluctuations in the indoor temperature, which reduces the user's temperature experience

Abstract

The invention relates to the technical field of air conditioners, and discloses a control method of an air conditioner. The control of the air conditioner comprises the steps that under the adjusting effect of the air conditioner, before the actual indoor temperature approaches the set indoor temperature and reaches the set indoor temperature, the first actual indoor temperature is obtained; a first temperature difference value between the set indoor temperature and the first actual indoor temperature is obtained; obtaining the interval duration required for reducing the absolute value of the first temperature difference value from the first temperature threshold value to the second temperature threshold value; wherein the second temperature threshold value is smaller than the temperature dead zone threshold value; determining a first compressor frequency and a first fan rotating speed corresponding to the interval duration according to the corresponding relation of the duration, the compressor frequency and the fan rotating speed; controlling the air conditioner according to the first compressor frequency and the first fan rotating speed. By adopting the control method of the air conditioner, indoor temperature fluctuation can be reduced, and the temperature experience of a user is improved. The invention further discloses a control device of the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of air conditioners, for example, to an air conditioner control method, a control device, and an air conditioner. Background technique [0002] At present, air conditioners usually use a proportional-integral-derivative (PID) control algorithm to achieve indoor temperature control. In the PID control algorithm, the greater the temperature difference between the actual indoor temperature and the set indoor temperature, the higher the The greater the operating frequency, the stronger the cooling / heating capacity of the air conditioner, and the easier and faster the actual indoor temperature can reach the set indoor temperature to eliminate the temperature difference; and, when the temperature difference is within the dead zone temperature range. In this case, the air conditioner stops running. [0003] In the process of implementing the embodiments of the present application, it is found that at lea...
