  Ensuring the longevity of an industrial air cooled chiller involves a series of diligent maintenance practices designed to maintain optimal performance and prevent premature wear. Regular inspections and upkeep are critical for the efficient operation of these systems. For an   air cooled screw chiller , frequent checks of key components such as the compressor, condenser coils, and evaporator are essential. The compressor should be monitored for any signs of wear or inefficiency, like unusual noises or vibrations, which could indicate potential issues. Keeping the condenser coils clean is equally important, as dirt and debris can obstruct airflow and reduce the system's efficiency. Maintaining proper refrigerant levels is another crucial aspect of prolonging the life of an  industrial air cooled chiller . Low refrigerant levels can cause the system to overheat, potentially damaging the compressor and other components. Regular monitoring and replenishment of refrigerant ...

  It is inevitable that the chiller will produce sound when it is working. For example, when the fan rotates, the fan blades rub against the air, it will produce sound. Normal sound is allowed. However, even the sophisticated refrigeration equipment will appear after a long period of use. Fault. Then, the editor of   Oumal Chiller   will take you to understand the causes and solutions of the noise produced by the chiller. First, find the reason from the parts that are easy to check and observe: 1. Are the anchor screws loose? The chiller is fixed on the ground. After running for a long time, the anchor bolts will be loose, and the chiller will be unstable, which will cause noise. This situation can be solved by replacing the anchor bolts, and vibration reduction can also be installed if conditions permit. The purpose is to make the chiller firmly fixed on the ground. 2. Whether the connecting pipeline is firm There are large and small pipes on the chiller, connecting the ...

  Air-cooled chillers , as a kind of more efficient refrigeration equipment in chiller products, are widely used in the domestic industrial market and become necessary equipment for many industrial production. ​ At the same time, although the air-cooled chiller is equipped with multiple protection devices, these are all to prevent the failure from directly damaging the unit. If the company wants to ensure that the air-cooled chiller has high cooling efficiency and long service life, it must remember to do regular maintenance. So, how should the normal safety maintenance and testing of air-cooled chillers be carried out? 1) Check the stability of voltage and current When the air-cooled chiller works normally, the voltage is 380V (the voltage of DYJ-01A～DYJ-02A is 220V, and the voltage of other regions abroad also has 410V, etc.), and the current is normal within the range of 11A-15A; 2) Check the compressor regularly The compressor is the "heart" of the chiller, and its qualit...
