　　How to maintain an industrial water chiller machine?

　　1、 Regularly check whether the voltage and electric flow of the chiller are stable, and whether the sound of the compressor is normal. When the chiller works normally, the voltage is 380V, and the current is within 11A-15A.

　　2、 Regularly check the refrigerant of the chiller for leakage: refer to the parameters displayed on the high and low pressure gauge on the front panel of the host to determine. According to the temperature changes (winter, summer), the pressure display of the chiller also varies. When the chiller is working normally, the high pressure display is generally 11-17kg, and the low pressure display is normal within the range of 3-5 kg.

　　3、 Check whether the hot water system of the chiller is normal, whether the cooling tower fan and sprinkler shaft are in good operation, and whether the water make-up of the built-in water tank of the chiller is normal.

　　4、 When the chiller is in use for six months, the system should be cleaned once a year. The main cleaning parts include the cooling water tower, cooling water pipes, and condenser to ensure better cooling effect.

　　When the chiller is not in use for a long time, the circuit switches such as the water pump, compressor, and main power supply of the cooling tower should be turned off in a timely manner.

　　The manufacturer has already set the various protective devices for the industrial chiller unit, and users should not make any changes when using it.

　　Regularly check whether the hot water system of the chiller is normal, whether the cooling tower fan and sprinkler shaft operate well, and whether the water make-up of the built-in water tank of the chiller is normal. Regularly check the refrigerant of the chiller for leakage: refer to the parameters displayed on the high and low pressure gauge on the front panel of the host to determine.

　　When a fault alarm shuts down the unit, the alarm shutdown button should be pressed first, and then the cause of the fault should be checked. It is important to remember not to forcefully start and run the unit until the fault is resolved.

　　If there is no emergency during use, do not turn off the unit by cutting off the power supply at will; If the unit is stopped for a long time in winter, first turn off the unit, then turn off the main power supply, and drain the water in the chiller.

　　When using industrial chillers, it is necessary to keep the machine room clean and well ventilated, and regularly clean the condenser to ensure the normal operation of the unit.
