Solution Overview

Problem

Existing mobile refrigerant systems lack comprehensive monitoring of operational performance and location data, making it difficult to diagnose equipment failures, predict maintenance needs, and determine liability for system malfunctions or damage.

Innovation Solution

A system incorporating a GPS receiver for location tracking and a performance monitor that collects data on parameters like airflow, humidity, vibration, sound, speed, voltage, and frequency, combined by a processor to provide a comprehensive signal for real-time monitoring and analysis of the refrigerant system's performance and position.
