How To Deal With The Low Evaporation Pressure Of A Water-cooled Chiller?

Water cooled chillers are widely used in textile factories, electronics factories, chemical factories, plastic factories, ink printing factories, etc. They mainly provide low-temperature chilled water at 3-30 ℃ to cool the equipment, thereby improving the quality rate of products and improving work efficiency.
Because each manufacturer produces different chillers, it is recommended that you first consult the manufacturer of the water-cooled chiller that supplies you. It would be even better if they could provide after-sales service. However, we can still provide assistance in analyzing and eliminating the causes of low evaporation pressure in water-cooled chillers.
1. Perhaps due to insufficient refrigerant, the evaporation pressure of the water-cooled chiller is too low. Therefore, simply add the corresponding refrigerant. But Dongxing Refrigeration should remind one thing: if the refrigerant is insufficient, be sure to check for internal leakage. If there is internal leakage, it needs to be repaired, otherwise even if refrigerant is added, it will still leak directly and the problem cannot be solved.
2. If the expansion valve of the water-cooled chiller is opened too small or the valve hole is blocked, it can also cause the evaporation pressure to be too low. Normal use can be restored by opening the expansion valve and eliminating valve hole blockage.
3. It may be caused by blockage in the supply pipeline. After inspection, simply eliminate any dirt in the supply pipeline and solve the blockage problem.
4. Is the malfunction caused by oil accumulation inside the evaporator? If so, simply drain the oil.
5. The low evaporation pressure caused by clogging of the drying filter. Just clean and replace the drying filter.
6. If the solenoid valve of the water-cooled chiller does not work, this phenomenon can also occur. The solenoid valve can be repaired or replaced to restore normal use.
7. It may also be caused by the "ice blockage" of the expansion valve, so first check the cause and remove the "ice blockage" of the expansion valve.
