1. 蒸发吸热基本原理：制冷剂在低压蒸发器中汽化吸收热量，通过物联网模块可实时监控电流与功率变化。
2. 常见故障：不制冷或结冰过厚。排查步骤：检查温控设置、化霜定时器是否损坏、或系统微量泄漏。
1. Evaporative Heat Absorption: Refrigerant vaporizes in low-pressure evaporator to absorb heat, monitored via IoT.
2. Common Faults: Not cooling or heavy frosting. Check temperature settings and defrost timer.
