Maintenance inspection of chiller for production type freeze dryer
　　 Production type freeze-dryer equipment used for large-scale freeze-dry processing. The heat dissipation method is water-cooled. The principle is that the chiller provides cooling water to enter the water condenser of the production type freeze dryer to perform heat exchange with the refrigerant or refrigeration oil, taking away the heat and reducing the temperature of the cooled medium. The screw compressor motor is water-cooled, and the cooling water passes through the compressor to take away the heat generated when the compressor is working.
　　Maintenance and inspection of chiller for cooling of production type freeze dryer:
　　1. No cooling water supply or insufficient flow, which may cause compressor damage and safety valve opening, resulting in refrigerant leakage;
　　2, the pressure and flow of cooling water meet the design requirements of the lyophilizer (detailed parameters according to the model);
　　3, the cooling water inlet temperature meets the design requirements of the freeze dryer;
　　4, cleanliness of cooling water (clear visual inspection, no suspended matter);
　　5.The temperature difference between the inlet and outlet of cooling water is ≤5 ℃;
