As an important refrigeration equipment in industrial production and commercial places, the operation status of water chillers directly affects production efficiency and usage costs. Regular maintenance not only reduces the occurrence rate of malfunctions but also maintains the cooling effect of the equipment and extends its service life. The following shares the scientific maintenance methods for chillers from multiple aspects.
Daily maintenance should focus on basic cleaning and condition observation. Before starting up the equipment every day, it is necessary to check whether there is any damage or leakage on the appearance of the equipment, clean the dust and debris on the surface of the body and around it, and ensure that the heat dissipation and ventilation are not hindered. During operation, pay attention to the cooling effect, operating noise and pressure gauge reading. If any abnormal fluctuations occur, stop the machine in time for inspection. At the same time, keep the computer room environment clean and dry to prevent dust and corrosive gases from entering the equipment.
Regular maintenance focuses on the inspection and care of core components. Every 1 to 3 months, the heat dissipation pipes of the condenser and evaporator need to be cleaned to remove internal scale and impurities and improve heat exchange efficiency. Check the refrigerant level. If there is any leakage, repair it in time and replenish the refrigerant to avoid affecting the cooling effect due to insufficient dosage. In addition, the lubricating oil should be tested. If it deteriorates or emulsifies, it should be replaced in time. At the same time, the oil filter should be cleaned or replaced to ensure the normal operation of the compressor.
Seasonal maintenance requires targeted protective measures. Before a long-term shutdown, the cooling water or chilled water in the system should be drained to prevent the pipes from cracking in a low-temperature environment. Before restarting, thoroughly check whether the circuit connections are firm, test the sensitivity of the control system, and ensure that all components work in coordination. For water chillers installed outdoors, it is necessary to take good protective measures against rain, sun and corrosion to extend the outdoor service life of the equipment.
The maintenance of water chillers should follow the principle of "prevention first and regular inspection". Through standardized maintenance procedures, not only can the losses caused by sudden failures be reduced, but also the equipment can always remain in an efficient operating state, providing a stable guarantee for production and use.
