Abstract

The invention relates to the technical field of air conditioners, in particular to a refrigerant water content detection method and an air conditioning system. The air conditioning system comprises a refrigerant circulating system, the refrigerant inlet side of a throttling assembly in the refrigerant circulating system is communicated with a bypass pipeline, and the bypass pipeline is provided with a collecting container and a water content analyzer. The detection method comprises the steps of controlling the collection container to collect refrigerants according to an operation mode of the air conditioning system; judging whether the collection container completes collection of the refrigerant or not, and if yes, controlling a water content analyzer to analyze the water content of the refrigerant in the collection container; and whether the water content exceeds a preset water content threshold value or not is judged, and if yes, the air conditioning system is controlled to prompt a fault signal of excessive water content. According to the method for detecting the water content of the refrigerant and the air conditioning system, the refrigerant can be directly sampled and detected online, manpower and time are hardly consumed, and inspection is not needed, so that the maintenance time is shortened, and the user experience degree is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method for detecting the water content of a refrigerant and an air conditioning system. Background technique [0002] Before the after-sales installation of the air conditioning system, the refrigerant may enter water due to the high ambient humidity. If the water is not cleaned out, it may cause problems such as copper plating of the compressor coil, deterioration of lubricating oil, overheating and burning. Ice blockage may occur in some places, which will affect the operation effect of the system. Therefore, it is especially important to detect the water content of the refrigerant. [0003] At present, the common way to test the water content of refrigerants is to take samples off-line and submit them for inspection. The process is complicated, time-consuming and labor-intensive. [0004] To sum up, how to overcome the above-mentioned defects of the existing method...
