Abstract

The invention discloses a method, device and system for controlling the operation frequency of a variable frequency air-conditioner. The method includes the steps that under the condition that the temperature difference of the current environment temperature and a preset temperature meets a first preset condition, the first operation frequency of the variable frequency air-conditioner operating at present is lowered, and the lowered second operation frequency is obtained; after the variable frequency air-conditioner operates at the second operation frequency in first preset time, whether the temperature difference meets a second preset condition or not is detected; under the condition that the temperature difference does not meet the second preset condition, the variable frequency air-conditioner is controlled to operate at the first operation frequency; under the condition that the temperature difference meets the second preset condition, the second operation frequency is lowered continuously. By the adoption of the method, device and system, the technical problem that when the variable frequency air-conditioner operates to achieve temperature balance in the prior art, whether the operation frequency for maintaining temperature balance at present is accurate or not cannot be determined is solved.

Description

technical field [0001] The present invention relates to the field of air conditioner frequency control, in particular to a method, device and system for controlling the operating frequency of an inverter air conditioner. Background technique [0002] At present, for the frequency control of the frequency conversion air conditioner, the existing technology adopts a method of adjusting the operation frequency of the air conditioner according to the load demand to control the operation frequency of the frequency conversion air conditioner to achieve the purpose of energy-saving operation. In the prior art, when the difference between the ambient temperature of the inverter air conditioner and the temperature set by the user gradually narrows, the operating frequency of the inverter air conditioner gradually decreases; when the ambient temperature of the inverter air conditioner is the same as the user’s set temperature, if the current If the operating frequency makes the enviro...
