Abstract

The invention relates to the technical field of control over air conditioners, in particular to a control method and control device for the air conditioners. The control method for the air conditioners comprises the steps: setting an initial rotary speed of an outdoor fan according to an outdoor environmental temperature when the air conditioner enters a heating mode; obtaining the temperature of an indoor heat exchanger and comparing with a first preset temperature value and a second preset temperature value; if the temperature of the indoor heat exchanger is larger than the first preset temperature value, reducing the rotary speed of the outdoor fan; if the temperature of the indoor heat exchanger is not larger than the first preset temperature value and not smaller than the second preset temperature value, then keeping the current rotary speed of the outdoor fan; and if the temperature of the indoor heat exchanger is smaller than the second preset temperature value, then increasing the rotary speed of the outdoor fan. The problem that the rotary speed of the fan cannot be automatically adjusted according to different air conditioner operation environments is solved, the fan can save energy when operating at a relatively lower rotary speed, the noise of an outdoor unit is also reduced, an air conditioner system is more stable in operation, shutdown and starting up times of the outdoor fan are reduced, and the use comfortableness of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an air conditioner control method and control device. Background technique [0002] With the application of air conditioners more and more widely, generally in the outdoor temperature range of -15 to 30 degrees, air conditioners have heating needs. Most of the existing air conditioners, in the heating mode, the outdoor fan runs at a fixed speed, and the outdoor fan cannot adapt to the change of the outdoor environment temperature and the temperature change of the indoor evaporator, resulting in a certain waste of energy consumption, unstable and comfortable system A series of problems such as low temperature and high noise. [0003] When a conventional air conditioner is in heating operation, the greater the speed of the outdoor fan, the better the heat exchange effect of the refrigerant in the outdoor heat exchanger, which leads to the high temperature of the re...
