Embodiment Construction

[0031] Such as figure 2 As shown, the air conditioner fluorine deficiency detection method proposed by the present invention needs to use environmental parameters, connecting pipe size parameters and air conditioner electrical parameters. . Such as image 3 The temperature shown is an important parameter affecting the operation of the air conditioner. In a preferred embodiment, the environmental parameter is the external ambient temperature of the outdoor unit, the size parameter of the connecting pipe is the length of the connecting pipe, and the electrical parameter of the air conditioner is the current value of the air conditioner.

[0032] The steps of the method for detecting fluorine deficiency in an air conditioner will be described in detail below in conjunction with preferred embodiments. It should be emphasized that the detection method of the present invention is only suitable for use when the air conditioner is turned on for the first time after it is installed ...

Abstract

The invention discloses a fluorine lack detection method and detection device for an air conditioner and the air conditioner. The fluorine lack detection method for the air conditioner comprises the following steps: S1, acquiring corresponding normal air conditioner electric parameters from a pre-formulated corresponding relationship table of environment parameters, dimension parameters of connecting pipes and normal air conditioner electric parameters according to the current environment parameters and the current dimension parameters of connecting pipes; and S2, detecting the current air conditioner electric parameters to judge whether the air conditioner electric parameters are smaller than or equal to the normal air conditioner electric parameters or not, if so, the air conditioner islack of fluorine. The fluorine lack detection method can be used for detecting whether the air conditioner is lack of fluorine or not accurately.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for detecting fluorine deficiency in an air conditioner, a detection device and an air conditioner. Background technique [0002] Due to the special housing structure and diverse customer needs, the air conditioner often needs to lengthen the connecting pipe to meet the requirements during the installation process. After the connecting pipe is extended, additional refrigerant must be added to ensure the circulation of refrigerant in the system. However, in the actual installation process, there are often cases of under-adding or missing refrigerant. The low mass flow rate of refrigerant will lead to insufficient cooling capacity, high compressor discharge temperature, and high winding temperature. problems such as burning. [0003] In the prior art, after installing a long connecting pipe between the indoor unit and the outdoor unit, a pressure gauge is used to...
