Maintenance Of Chillers

During winter, low ambient temperatures pose several challenges for chillers. Proper usage and maintenance are essential to ensure stable operation, extend the equipment's lifespan, and reduce operational costs. Hengde, a leader in the refrigeration equipment industry, has extensive experience in the research, production, and maintenance of chillers. Below are the key points and maintenance guidelines for industrial chiller use in winter, based on Hengde’s expert advice.   1. Pre-Startup Key Checks Water System Inspection Winter temperatures can cause water to freeze, so it’s crucial to thoroughly check both the cooling and chilled water systems. Ensure the water level is normal, and that the water is clear and free from impurities. If the water quality is poor, it should be treated or replaced. Additionally, inspect the water system's filters, clean or replace the filter elements to ensure smooth water flow and prevent ice blockages in the pipes.   Insulation measures inspection Check whether the insulation layer of each component of the industrial chiller is intact, especially the pipes and water tanks. If the insulation layer is damaged, the heat loss of the equipment will accelerate in a low temperature environment, energy consumption will increase, and the water system may also freeze. If damage is found, it is necessary to repair or replace the insulation material in time.   Electrical System Pre-Inspection Quickly check the electrical wiring for visible damage and ensure that terminal connections are secure. Verify that the power supply voltage is stable and within the chiller's rated voltage range. Hengde industrial chillers are equipped with an intelligent voltage monitoring system, but a manual inspection can help identify potential issues before they arise.   2. Operating Precautions Insulation measures inspection Check whether the insulation layer of each component of the chiller is intact, especially the pipes and water tanks. If the insulation layer is damaged, the heat loss of the equipment will accelerate in a low temperature environment, energy consumption will increase, and the water system may also freeze. If damage is found, it is necessary to repair or replace the insulation material in time.   Monitor Temperature Fluctuations In winter, the lower ambient temperature reduces the cooling load on the industrial chiller. It’s essential to closely monitor the temperatures of the evaporator, condenser, as well as the outlet temperatures of industrial chilled and cooling water. Based on these readings, adjust the operational parameters accordingly to prevent prolonged low-load operation, which can reduce compressor efficiency and increase energy consumption. Hengde industrial chillers feature an intelligent control system that automatically adjusts based on temperature fluctuations, ensuring efficient operation.   Insulation measures inspection Check whether the insulation layer of each component of the industrial chiller is intact, especially the pipes and water tanks. If the insulation layer is damaged, the heat loss of the equipment will accelerate in a low temperature environment, energy consumption will increase, and the water system may also freeze. If damage is found, it is necessary to repair or replace the insulation material in time.    Prevent Ice Formation In cold weather, the risk of water system freezing is higher. To prevent freezing, add an appropriate amount of antifreeze to the water, and ensure that the water system circulates properly. If any signs of freezing are detected, immediately shut down the system, thaw it, and restart it only after ensuring the water flow is restored.   Hengde not only offers high-performance industrial chillers but also provides comprehensive technical support and after-sales services.
