Industrial chiller operation of the three major circulation system

An industrial chiller is a device used for refrigeration, usually for cooling and freezing processes in industrial production. Its main principle is to absorb heat from industrial equipment or production processes through a circulation system and release it to the external environment. The operation of an industrial chiller relies on three main circulation systems: the refrigeration circulation system, the cooling water circulation system and the electrical control system.

First is the refrigeration circulation system, which is the core part of an industrial chiller. The system consists of a compressor, condenser, expansion valve and evaporator. The working process of the refrigeration cycle system is to compress the low-temperature and low-pressure vapor into a high-temperature and high-pressure gas through the compressor, and then the gas is discharged into the condenser to dissipate the heat through the cooling water or air, so that the gas is cooled into a high-pressure liquid state. Next, the high pressure liquid is depressurized through the expansion valve and becomes low temperature and low pressure steam, which then absorbs heat and cools down through the evaporator to become low temperature and low pressure liquid again, and the cycle repeats.

Next is the cooling water circulation system, which is used to dissipate heat and keep the system running stably. The cooling water circulation system includes components such as water pumps, cooling towers and water piping. The industrial chiller pumps cooling water into the system through the cooling water circulation system, and then circulates it again after dissipating heat through the cooling tower. Stable operation of the cooling water circulation system is essential to ensure the cooling effect and system reliability.

Finally, the electrical control system is used to monitor and control the operation of the entire industrial chiller. The electrical control system usually consists of sensors, controllers, electrical components and so on. By monitoring the working status of the refrigeration circulation system and the cooling water circulation system, the electrical control system can adjust the operating parameters of the system in real time to ensure the stable operation and efficient refrigeration effect of the industrial chiller. The electrical control system can also provide fault diagnosis and alarm functions, timely detection and treatment of system failures to ensure the continuity and reliability of production.

Overall, the operation of the industrial chiller relies on the synergy of the three major circulation systems. The refrigeration circulation system realizes the absorption and release of heat, the cooling water circulation system provides a guarantee of heat dissipation and stable operation, and the electrical control system monitors and controls the operation of the whole system. Only when these three systems work well together, the industrial chiller can effectively complete the cooling task and ensure the normal operation of the production process.
