The production-type freeze dryer equipment used for large-scale freeze-drying processing is water-cooled, and is cooled by a matching chiller. The principle is that the chiller provides cooling water into the water condenser of the production lyophilizer 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 inspection of chiller for production type freeze dryer:
　　1.The cooling water is not supplied or the flow is insufficient, which may cause the compressor to be damaged and the safety valve to open, resulting in refrigerant leakage;
　　2. The pressure and flow of cooling water meet the design requirements of the freeze dryer (detailed parameters are based on 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 ℃;
