　　What is the correct maintenance method for a 5 ton water chiller?

　　Maintain a clean appearance of the chiller filter screen, with air circulating near the filter screen, and regularly clean the filter screen. Usually, it is best to blow clean the filter screen with compressed air every three weeks. Reduce the appearance of mold sweating. Before stopping the injection molding machine, close the cold water gate of the corresponding mold or turn off the chiller to increase the water temperature in the mold cavity and prevent mold rust.

　　If the chiller has been in use for more than half a year, or if there are frequent problems with high and low pressure engines, or if the cooling capacity decreases, please organize technical personnel to clean the radiator (if the chiller is equipped with a pressure gauge, is the high pressure gauge force higher than 300PSI? If it exceeds this, the appearance of the radiator should be cleaned and kept clean to improve its effectiveness).

　　1. The chiller unit should be regularly inspected, including the heat transfer of the three parts of the compression evaporation condenser.

　　2. When the ambient temperature is too high or too low, it is necessary to adjust the operating time and startup frequency of the compressor appropriately.

　　3. When the refrigeration system malfunctions, it should be repaired in a timely manner to avoid causing greater damage.

　　4. Long term unused chillers should drain the cooling water and lubricating oil from the condenser after turning off the power.

　　5. Regularly clean and descale all parts of the chiller to ensure the normal and efficient operation of the refrigeration system and extend its service life.

　　6. Regularly observe the reading of the refrigerant flow meter and adjust the liquid supply at any time.

　　7. Regularly check the oil level and quality changes of the refrigeration oil.

　　8. Timely replenish refrigerant oil and refrigerant (r22) according to usage.

　　9. Pay attention to protecting the heat dissipation fins of the condenser and evaporator from being blocked by debris, which will affect their heat transfer performance.
