Water-cooled chiller need to use with the water pump and the cooling water tower, water will be used, unit high pressure alarm tend to due to water quality problems or in the use of debris into the unit, there will be high and low voltage alarm, then these problems we the how to deal with?
1, should first check whether the normal work of the pump and cooling tower is open. When the other components of the unit are normal, then there will be a cooling tower only when not working pressure alarm;
2, if the cooling water circulation system and expansion valve (capillary) do not have a problem, still under high-pressure alarm, it is necessary to check the cooling tower water is not clean, dry filter is not blocked. If necessary, add water to the water treatment equipment, cleaning the condenser, etc.;
3, if the pump and the cooling tower are normal operation, there is still a high pressure alarm, at this time we have to check the capillary (expansion valve) whether there is no blockage, or whether there is a leak.
4, the above steps are completed when the check is normal, it depends on the high / low pressure table in the data, in order to determine whether there is no leakage of refrigerant, or air to enter.
Based on years of experience in the East Star, water-cooled chiller appears the basic reason of the high pressure alarm is poor water quality, there are impurities from entering the water supply hole, hampered the cooling effect of the cooling tower, we should remove impurities, water quality testing, the appropriate processing work to prevent impurities from entering the cooling tower, the normal operation of the effect of water-cooled chiller, causing water cooled chillers of high pressure alarm.
