Variable frequency air conditioner frequency control method and device and air conditioner

Abstract

The invention provides a variable frequency air conditioner frequency control method, a variable frequency air conditioner frequency control device and an air conditioner, and relates to the technicalfield of air conditioners. The variable frequency air conditioner frequency control method includes: confirming that the air conditioner runs under a heating mode, entering a forcing frequency control stage, and controlling a compressor to run at the maximum frequency allowed at present; acquiring first indoor environment temperature when starting the compressor; acquiring second indoor environment temperature after the compressor and an indoor draught fan both run for a first preset time; judging if meeting conditions of exiting from the forcing frequency control stage according to the firstindoor environment temperature and the second indoor environment temperature; and if yes, exiting from the forcing frequency control stage, and controlling the compressor to run at frequency confirmed according to difference value between the indoor environment temperature and set temperature. The variable frequency air conditioner frequency control method can solve running abnormity caused by uneven distribution of a temperature field to the air conditioner, automatically realizes accurate indoor environment temperature detection, guarantees accuracy and reliability of system temperature control, and improves user experience.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a frequency control method and device for frequency conversion air conditioners and an air conditioner. Background technique [0002] With the rapid development of my country's economy and culture, people's living standards have also been greatly improved. In order to meet the needs of life, the use of air conditioners has also been more and more widely popularized. With the advancement of consumption concepts, temperature comfort is no longer the only requirement people have for air conditioners. Health, energy saving, environmental protection and other aspects have gradually become the focus of people's attention. Inverter air conditioners gradually occupy an important position in the air conditioner market due to their high efficiency, energy saving, small temperature difference, low noise, and high comfort. [0003] When the inverter air conditioner is in h...
