In office buildings and industrial complexes up and down the country, management teams are trying to reduce costs as much as possible. Maybe it's due to the "age of austerity," or it's simply good business practice, but it's not prudent to spend a penny more than is necessary. These managers will frequently raise an eyebrow at the monthly energy bills that arrive through the post and wonder what they can do to save cash. They may not realise that the building's chillers are one of the main energy hogs and this is often due to poor management. What should they be looking at in particular, to achieve greater efficiency?
Managers and engineers may not like to hear it, but one of the biggest reasons for chiller inefficiency is a poor operational plan. Often, they will try to get more out of the chiller than it was designed to do, like increasing the water flow to try and produce a higher output. However, if the flow rate is greater than the manufacturer recommended limit, target efficiency will go way down and this could also lead to malfunction.
The tubes which feed chillers tend to be made of copper and a certain amount of corrosion can be suffered due to a chemical reaction. When this happens, it can affect the flow of water and can also lead to a buildup of sediment. In time, this will lead to tiny perforations in the tubing and loss of refrigerant. This can be avoided to a large extent by treating the pipes and parts with a special epoxy solution.
Loss of Efficiency
Finally, one of the most avoidable errors is a failure to apply maintenance practices in accordance with manufacturer recommendations. The chiller will, even if maintained well, be expected to lose a certain amount of efficiency per year as it gets older. However, if it is poorly maintained the energy usage can shoot up, meaning that it will simply cost a lot more to produce the same level of cooling. It's important to work with a chiller maintenance company.
As any organisation can achieve significant cost savings by paying close attention to operation and maintenance, it's a good idea to get in touch with specialist technicians as soon as possible in order to turn over a new leaf. By bringing in a dedicated maintenance company, chiller efficiency can be reset and a more progressive and frugal plan initiated.Share
