What are The Effects of Water Quality on Water Cooled Industrial Chiller?
The cooling performance of water-cooled industrial chillers must be strictly controlled if they want to remain stable. In the daily use of water-cooled machine, if the enterprise does not pay enough attention to whether the water quality is good or bad, then all kinds of sudden faults will be produced in the process of using the equipment. What are the effects of water quality on water-cooled industrial chillers?
1. Hardness
The water cooled chiller need to use a large amount of water during operation, when the water quality is bad, even if the cooling water machine runs efficiently, it is still unable to achieve the purpose of rapid cooling in a very short time. The longer the equipment runs, the more energy it consumes, which affects the normal use of the cold water machine, even the cost of the cold water machine is increasing, which is not conducive to the stable operation of the cold water machine for a long time. Only the water with suitable hardness is able to ensure the stable operation of chillers. If the water quality is relatively bad, it will affect the operation of chillers. Especially in the state of high efficiency operation, it is easy to cause various scale problems inside the chiller. After scaling to a certain extent, it will affect the normal use of chillers.
2. Water flow
Water flow will also affect the stable operation of water-cooled chillers. Too large or too slow of water flow will restrict the operation efficiency of the equipment and even cause the cooling performance of the chiller. In the range of rationalization, the continuous improvement of water flow can increase the operation safety of the chiller, at the same time, avoid the problem of small water flow and so on, and affected the operation of the chiller to be, resulting in irreparable loss.
The quality of water in chillers directly affect the stability of the equipment. The operation of water cooled water chiller is inseparable from the water source, the better the water quality of the water source, the lower the probability of the scale of the water cooler in the operation of the enterprise. The industrial chiller will be used on the premise of removing the scale threat, and the operation fault range of the equipment is effectively reduced.
