{"response":"### Energy Analysis Report: Main Refrigerator\n\n**1. Overall Energy Status**\nThe unit is operating within normal parameters with stable power consumption and excellent voltage compliance.\n\n**2. Key Metrics Summary**\n*   **Average Consumption:** 526.64W (Range: 489.5W \u2013 612.6W).\n*   **Voltage:** 231.5V avg (Stable; 100% EN50160 compliance).\n*   **Power Factor (PF):** 0.706 avg (Range: 0.68 \u2013 0.76).\n*   **Period Consumption:** 21.83 kWh over ~41 hours.\n*   **Operational Cost:** ~2,401 PKR (based on 110 PKR\/kWh).\n\n**3. Notable Observations**\n*   **Efficiency:** The Power Factor (PF) is relatively low (avg 0.706). While common for refrigeration compressors, this indicates reactive power losses; consider a capacitor bank check if utility penalties apply.\n*   **Stability:** Voltage regulation is optimal with zero sags or swells recorded.\n*   **Load:** The unit is consistently active, reflecting steady cooling cycles without anomalous power spikes or erratic cycling behavior.","cached_at":"2026-09-09T10:08:31+05:00","expires_at":1788930811}
