Refrigeration system monitoring and alerting for servicing
The patent US12044466B2 describes a comprehensive system designed to monitor and manage the operational status of refrigeration systems. Central to this system are various sensors, including a door sensor, temperature sensor, power sensor, and compressor sensor, which collectively provide critical data regarding the door status, internal temperature, power consumption, and acoustic signals of the compressor. A remote computing system processes this information to assess whether the temperature exceeds a predetermined threshold. If the temperature is elevated, the system checks the door status and power consumption. Based on these evaluations, it can determine if the compressor is functioning correctly and whether the refrigeration system requires servicing.
The system is equipped to send alerts to user devices, indicating specific issues such as an open door, the need for servicing, or potential problems with the compressor. Additionally, it can issue instructions to the refrigeration system, such as activating alarms or switching to an off mode if necessary. The patent outlines various scenarios for alert generation, including conditions where the compressor operates within or outside predetermined acoustic ranges and power consumption levels. This multifaceted approach aims to enhance the reliability and efficiency of refrigeration systems, ensuring timely maintenance and optimal performance.
