Abstract

The invention provides an air conditioner fluorine shortage detection method and device and an air conditioning system. The method comprises the steps that after a compressor of a to-be-detected air conditioner operates for a first set duration with the actual working frequency not smaller than preset frequency, a first temperature parameter of an indoor coiled pipe, a second temperature parameter of an indoor environment and a third temperature parameter of an outdoor environment are collected; when the absolute value of the difference value of the second temperature parameter and the first temperature parameter is smaller than a first preset threshold value and the absolute value of the difference value of the third temperature parameter and the second temperature parameter is smaller than a second preset threshold value, the to-be-detected air conditioner operates in a target working state; and after a second set duration, whether the to-be-detected air conditioner is short of fluorine or not is determined according to the acquired average operating current of the compressor of the to-be-detected air conditioner within a third set duration, the acquired coiled pipe average temperature of the indoor coiled pipe within the third set duration and the acquired indoor average temperature of the indoor environment within the third set duration. According to the technical scheme, the fluorine shortage detection efficiency is high.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a method and device for detecting fluorine deficiency in an air-conditioner and an air-conditioning system. Background technique [0002] With the development of science and technology and the continuous improvement of economic level, air conditioners have been widely used. Most of the air conditioners on the market use Freon as the refrigerant. When the air conditioner lacks fluorine (the remaining proportion of Freon is less than the corresponding value), it may cause the air conditioner to be unable to perform effective cooling or heating. [0003] At present, whether the air conditioner lacks fluorine is mainly detected by manual inspection. [0004] Since the manual detection method will occupy a large amount of human resources, and cannot detect whether the air conditioner is deficient in fluorine in time, the detection efficiency of fluorine deficiency ...
