The harsh operation mode not only reduces the efficiency of the chiller, but also reduces the life of the chiller. Most of these practices are the result of one or two situations:
Trying to get a chiller to do something that it was not designed to understand the consequences of a particular action
For example, a common practice is to increase the flow of cold water through the cooler. The belief is that with higher flow rates, more cooling water will be available. However, in practice, the increase in flow through the cooler exceeds the limits specified by the manufacturer, which actually reduces the operating efficiency of the chiller.
Equally important, the flow rate increases the rate of erosion in the chiller tubes than those recommended. As a result, the early chiller shell and tube failed. In addition, PES provides maintenance of the chiller to increase the efficiency of the chiller. Through our coating process, we remove any bad metals or defects due to poor handling practices.
Good maintenance of the chillers is important for the efficient operation of all plant equipment. However, few such areas are more visible than the maintenance of chillers in the plant. Most new high efficiency centrifugal chillers have a full load efficiency of approximately 50 kW per ton.
If the chiller is properly maintained, its full load efficiency can reach 55-60 kW per ton within five years. Every year, this means that a poorly maintained cooler will use 20-25% of the energy. Regular inspection and recording of maintenance logs is an important operation. This helps control things and saves you money in the long run. Our team can also remove any bad metals and defects to reduce the time spent on repairs.
