In industry, water-cooled screw chillers are known for their stable performance, high energy efficiency ratio, low noise, and strong operability. It accounts for an increasing proportion of industrial refrigeration. It can not only provide refrigeration for hotels, guesthouses, commercial buildings, industrial and mining enterprises, etc., but also provide process cold water for food, textile, chemical, electronic and other industries. Therefore,Refrigeration Equipment in addition to ensuring the excellent manufacturing and installation and commissioning quality of the unit, its operational safety should also be guaranteed first.

The water-cooled screw chiller consists of 4 major components, the refrigerant circulation system, the oil circuit system, the cooling water circulation system and the chilled water circulation system. The safety inspection is also based on the safety management operation of the four major systems of the unit.

Not only that, the refrigeration operation unit should formulate equipment operating procedures based on the number of unit instructions and response product standards, as well as equipment characteristics and actual use experience, to strengthen equipment management, standardize equipment use, improve equipment integrity, and ensure Safe Production.

Although technological advancement has promoted the screw unit to gradually become intelligent and professional, especially the development of unit control system with automatic fault detection function, the failure rate of screw refrigeration units has been greatly reduced. However, once the unit fails, the sensor or some other equipment control system will generate an alarm, which will cause inconvenience to production and maintenance, so it is necessary to check whether the system is normal.

The safety checklist for general chillers includes the following: the sequence of normal startup and shutdown of the equipment; technical parameter values ​​during normal operation of the equipment; precautions for safe operation of the equipment; handling and reporting procedures in case of emergencies; basic requirements for daily maintenance of equipment .
