Refrigeration Principle
Adaptive PID Refrigeration Cycle:
1️⃣ Compression → Refrigerant pressurization
2️⃣ Condensation → Heat dissipation & liquefaction
3️⃣ EEV throttling → Low-pressure generation
4️⃣ Evaporation → Precision heat absorption from equipment
5️⃣ Inverter flow control → Maintains ±0.1℃ stability
