Problems solved by technology

[0005] Embodiments of the present invention provide an air-conditioning fan control method and device to at least solve the problem of the inconsistency between the air-conditioning output capacity and the indoor load existing in the existing air-conditioning fan control method, so that the air-conditioning output capacity can be kept consistent with the indoor load. When the load is heavy, ensure that the indoor temperature can reach the set temperature, and when the indoor load is light, it can reduce the number of times the compressor starts and stops

Abstract

The embodiment of the invention provides a control method and device for an air-conditioner draught fan. The control method and device for the air-conditioner draught fan can make the output capability of an air-conditioner and the indoor load be consistent. The control method comprises the steps that the indoor temperature is detected according to a preset first detection period; at the current detection moment, the temperature difference value of the indoor temperature and a setting temperature and the change rate of the indoor temperature are obtained, or the temperature difference value of the indoor temperature and the setting temperature and the variable quantity of the indoor temperature in one detection period are acquired; according to the temperature difference value and the change rate of the indoor temperature, or on the basis of the temperature difference value and the variable quantity of the indoor temperature in one detection period, the indoor draught fan of the constant-frequency air-conditioner is controlled to operate according to preset rules; the preset rules comprise that when the temperature difference value is within a preset threshold range, under the condition of a certain temperature difference value, the air speed of the indoor draught fan is decreased as the change rate of the indoor temperature / the variable quantity of the indoor temperature in one detection period is increased gradually. The control method and device for the air-conditioner draught fan are suitable for the field of air-conditioners.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner fan control method and device. Background technique [0002] At present, air conditioners can be divided into frequency conversion air conditioners and fixed frequency air conditioners. Among them, the fixed frequency air conditioner realizes the adjustment of temperature by adjusting the wind speed of the air conditioner fan. [0003] Taking the indoor fan as an example, the fixed-frequency air conditioner takes the temperature difference between the indoor temperature and the user-set temperature as the only control variable, and roughly divides the range of the temperature difference into several temperature difference intervals. Each temperature difference interval corresponds to a specific wind speed. The indoor temperature is detected systematically, and the wind speed is determined according to the temperature difference between the indoor temperature an...
