Variable-frequency air conditioner variable-frequency coefficient adjustable time-control temperature adjusting method and device and air conditioner

Abstract

The invention provides a variable-frequency air conditioner variable-frequency coefficient adjustable time-control temperature adjusting method and device and an air conditioner, and relates to the technical field of air conditioners. The method comprises the following steps that a first external command signal, a second external command signal and an ambient temperature are acquired, and according to a set temperature and a set output frequency, expected running time of the ambient temperature reaching the set temperature is determined; a frequency converter is controlled to be locked at theset output frequency for running according to the first external command signal, and actual running time of the frequency converter locked at the set output frequency for running is acquired; and whether the actual running time and the ambient temperature reach the preset conditions or not is judged according to the expected running time and the set temperature, and if the actual running time andthe ambient temperature reach the preset conditions, the frequency converter is controlled to no longer be locked at the set output frequency. According to the method, different frequency converter output frequencies are set so as to meet different requirements of a user on a temperature adjustment speed and power saving and energy saving, meanwhile, the sufficiency of temperature adjustment is measured in combination with the running time, the temperature adjustment control is reasonably carried out, and the use comfort is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method and device for time control and temperature regulation with adjustable frequency conversion coefficients of frequency conversion air conditioners and an air conditioner. Background technique [0002] At present, there are two types of air conditioners on the market: fixed frequency air conditioners and inverter air conditioners. The fixed-frequency air conditioner operates at a fixed frequency, drives the compressor to run at a fixed speed, and continuously starts and stops the compressor to adjust the indoor temperature. However, it is easy to cause unstable room temperature and bring inconvenience to users. In this context, inverter air conditioners are welcomed by users. In the prior art, the frequency conversion air conditioner is equipped with a frequency converter, and the speed of the compressor is changed by changing the output frequency of the ...
