AI Technical Summary
Existing refrigerant detection methods in refrigeration equipment lack accuracy and reliability in complex dynamic environments, and are particularly difficult to adapt to low-end freezers. Multi-sensor solutions are costly and difficult to apply.
By acquiring the compressor's runtime and temperature data from a single temperature probe, and combining time and temperature factors, a mathematical or machine learning model can be constructed to detect the refrigerant charge status, thereby reducing hardware costs and improving detection accuracy and stability.
Without increasing the number of sensors, it achieves accurate detection of refrigerant dosage, adapts to environmental changes, reduces false alarm and missed alarm rates, and is suitable for low-end freezer requirements.
