Abstract

The invention discloses an air conditioner and a control method and device thereof. The control method of the air conditioner includes that when difference between indoor environment temperature and target temperature is larger than a first preset value, temperature changing rate is smaller than a second preset value so as to greatly increase load operation parameters of the air conditioner, and the temperature changing rate is larger than the second preset value so as to increase the load operation parameters of the air conditioner in a small range; and when the difference between the indoor environment temperature and the target temperature is smaller than or equal to the first preset value, the temperature changing rate is smaller than the second preset value so as to reduce the load operation parameters of the air conditioner in a small range, and the temperature changing rate is larger than the second preset value so as to greatly reduce the load operation parameters of the air conditioner. By means of the air conditioner and the control method and device, an air conditioner load can be controlled precisely and fast refrigeration and heating can be achieved according to the environment temperature changing rate. In addition, when the indoor environment temperature reaches the temperature set by users, the environment temperature is prevented from being too cold and too hot or being unstable, and comfortableness of air conditioner products is improved.

Description

Technical field [0001] The present invention relates to the field of air conditioners, and in particular to an air conditioner and its control method and device. Background technique [0002] At present, when controlling the air conditioner, only the difference between the ambient temperature and the set temperature is considered. When the difference reaches a fixed value, the compressor, internal fan and other loads are controlled. The control has hysteresis, The indoor temperature is too cold and too hot, and only the difference between the ambient temperature and the set temperature is considered, which is prone to sudden cold and hot, affecting the comfort of the air conditioner. [0003] Regarding the problem of overcooling and overheating of the indoor temperature caused by the operation of the air conditioner in the related art, no effective solution has yet been proposed. Summary of the invention [0004] The main purpose of the present invention is to provide an air condit...
