Guide to Alarm Release and Common Fault Handling of Industrial Refrigeration Chillers
In the field of industrial production, industrial refrigeration chillers play a crucial role as they can effectively provide a stable low-temperature environment for various equipment and processes. However, in daily use, the chiller may experience various faults and issue alarms. This not only affects production progress but may also cause damage to the equipment. Therefore, understanding how to release the alarms of industrial refrigeration chillers and the handling methods for common faults is of utmost importance. I. The Importance of Chiller Alarms The alarm system of chillers is designed to promptly remind users of abnormal conditions in the equipment so that corresponding measures can be taken for handling. These alarm messages usually include excessive temperature, abnormal pressure, water flow faults, and more. If not addressed in time, it may lead to equipment damage, production interruption, and even safety accidents. II. Alarm Release Guide Understand the meaning of alarm codes Different chiller brands and models may have different alarm codes. Users should first consult the equipment manual to understand the specific meanings of various alarm codes. This will help quickly determine the cause of the fault and take appropriate solutions. Check the equipment operating status When the chiller issues an alarm, immediately check the operating status of the equipment. This includes checking whether parameters such as water temperature, pressure, and water flow are normal. At the same time, observe whether there are abnormal noises, vibrations, or leaks in the equipment. Eliminate the cause of the fault Based on the alarm code and equipment operating status, gradually eliminate the cause of the fault. For example, if there is an excessive temperature alarm, it may be caused by a clogged condenser, insufficient refrigerant, or a malfunctioning cooling fan. Take corresponding solutions for different fault causes. Reset the alarm system After eliminating the fault, the alarm system needs to be reset. Usually, this can be achieved by pressing the reset button on the equipment or operating in the control system. After resetting, observe whether the equipment is operating normally to ensure that the alarm has been released. III. Handling Methods for Common Faults Excessive temperature fault Causes: Clogged condenser, insufficient refrigerant, malfunctioning cooling fan, etc. Handling methods: Clean the condenser, add refrigerant, and check whether the cooling fan is working properly. If the cooling fan is malfunctioning, it should be replaced or repaired in time. Abnormal pressure fault Causes: Refrigerant leakage, clogged filter, malfunctioning expansion valve, etc. Handling methods: Check whether there is a leakage in the refrigerant pipeline, replace the clogged filter, and adjust or replace the expansion valve. If the pressure is too high, some refrigerant can be released to reduce the pressure. Water ...
