Cold Storage Structure, Classification and Operation Maintenance Guide
From 5℃ Fresh Rooms to -60℃ Deep Freezers: A Complete Guide to Cold Storage Types and Care
Cold storage facilities maintain stable temperature and humidity through mechanical refrigeration, serving food, medicine and chemical preservation. Types span high-temperature rooms (5-15℃), medium-temperature cold rooms (-5-5℃), low-temperature freezers (-25--18℃), ultra-low deep freezers (-60--45℃) and quick-freezing rooms (-40--35℃). A complete system comprises insulation enclosure, refrigeration unit, throttle components, heat exchangers, piping and intelligent electric control, with scroll, piston and screw compressors driving the cycle through condenser, liquid receiver, filter drier, expansion valve and evaporator. Common faults—high discharge pressure, liquid slugging startup, oil shortage and insufficient capacity—demand standardized troubleshooting for long-term stable operation. EXTRCOOL supplies variable-frequency cold storage systems.
