Cold Storage Classification Refrigeration Principle and Common Fault Maintenance Guide
Pre-Cooling to -25℃ Deep Freeze: Classification, the Four-Stage Cycle and a Fault Checklist
Cold rooms regulate temperature via artificial refrigeration, serving food cold chain, pharmaceutical, chemical and industrial fields, and are classified by function into pre-cooling rooms, quick-freezing rooms at -18℃ and below, low-temperature frozen storage at -18℃ to -25℃, ice storage and industrial process rooms, and by structure into civil and prefabricated assembly types. Modern systems rely on the vapor compression cycle's four processes—compression, condensation, throttling and evaporation. Common faults include high discharge temperature, low suction pressure, excessive discharge pressure, liquid return and slugging, plus oil shortage, phase loss, overload and unbalanced current. EXTRCOOL provides variable-frequency cold storage solutions.
