They are respectively represented as the usage time corresponding to the target air conditioner and the preset standard usage time. That is, the longer the usage time, the greater the risk of refrigerant leakage in the target air conditioner. It is represented by the number of marks corresponding to the target air conditioner.

By continuously monitoring the flow, the operating status of the system can be understood in real time, and the operating parameters can be adjusted or maintenance can be performed in time to ensure system efficiency and reliability.

[0031] Specifically, the pressure deviation coefficient, temperature deviation coefficient, and flow deviation coefficient in the target air conditioning refrigeration system are obtained and analyzed to confirm the refrigerant leakage, which can achieve early detection of refrigerant leakage, thereby preventing the leakage from being undetected for a long time, resulting in reduced energy efficiency and higher energy consumption, as well as potential equipment damage.
