💡 The subcooling and superheat of refrigeration equipment need to be detected and controlled properly, otherwise it will cause reduced system efficiency and equipment damage.
📊 Analysis:
Insufficient subcooling 🥶 can cause liquid flash evaporation, affecting refrigeration effect. The causes may be condenser fouling or insufficient refrigerant.
Excessive superheat 🔥 will increase compressor power consumption, reducing refrigeration effect. Insufficient superheat may cause liquid to enter the compressor, causing liquid hammer. The causes may be expansion valve issues or refrigerant contamination.
Regular detection of subcooling and superheat is needed to keep them within normal range: subcooling 5-8°C, superheat 8-15°C.
🔧 Solutions:
Regularly detect subcooling and superheat, find exceptions and troubleshoot causes timely.
Keep condensers and evaporators clean to avoid fouling blocking heat transfer.
Maintain the working status of expansion valves.
Ensure sufficient and uncontaminated refrigerant.
Monitor and maintain the system to ensure normal subcooling and superheat.
