Abstract

The invention discloses a method and device and system for detecting air conditioner coolants. The detection method comprises the steps of detection A, detecting if air conditioner coolants are sufficient; detection B, detecting if an outdoor unit coolant pipe of the air conditioner is abnormal; detection C, detecting if a coolant pipe of the air conditioner is abnormal; detection D, detecting if the coolants of the air conditioner are excessive. If the detection results of the diction A, the detection B, the detection C and the detection D are all no, the state of the coolants of the air conditioner is judged to be proper. By means of the method and device and system for detecting the air conditioner coolants, the problems that in the prior art, the detection mode for the state of the coolants of the air conditioner is tedious, and efficiency is low are solved, so that the purposes of simplifying the detection mode of the coolants of the air conditioner and improving the detection effect are achieved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a method, device and system for detecting refrigerants of an air conditioner. Background technique [0002] At present, in the product development of air conditioners, in order to ensure the normal operation of the air conditioner, the function of automatic refrigerant filling is generally developed in the air conditioner. detection. However, the current testing work is mainly done manually one by one, which is time-consuming and labor-intensive, and the work efficiency is low. Moreover, if the automatic perfusion fails, when the operation is performed manually, the fault point is not easy to find and debugging is difficult. [0003] Aiming at the cumbersome and inefficient detection methods of the refrigerant state of the air conditioner in the related art, no effective solution has been proposed yet. Contents of the invention [0004] The main purpose of the present inventio...
