Your chiller can last many years as long as you get into the habit of doing preventive maintenance. From an industrial perspective, the preventive maintenance will involve many simple but lengthy processes that you have to prepare for in advance. This article will be giving you the five main steps worth following when you want an efficient chiller. You will end up saving both time used for chilling and the money that would go to the extra energy burned in the process of chilling. Read on to learn about the tips already in use at the most chiller-efficient industrial installations in the country.
Rely on a daily operations log
The maintenance of a daily operation log helps you to document chiller performance so that you can tell the performance of the unit from a big picture and a detailed perspective. You can compare the data you get daily and the data you got when the performance and design at the setup time were to find out whether there are inefficiencies in the controls or any other part of the chiller. The process of evaluating the data you collect daily will help the chiller operator to know the history of the operating conditions and their effects on chiller performance. The analysis may offer information to act as an advanced warning of the potential problems you will be encountering. Consulting Cary Company or your chiller manufacturer may also be a good point for obtaining a list of recommended data points for your type of equipment.
Keep the tubes clean
The chiller unit has tubes that serve purposes of heat transfer. You must ensure they are clean at all times because the chiller’s performance directly corresponds with its ability to transfer heat. The process starts at the evaporator and condenser tubes. Therefore, keeping them clean will ensure that the chilling process is efficient and the presence of lengthy tubes in large chillers should not be a deterrent to the maintenance efforts. The mechanism for chilling remains the same in all types of chillers. Fouled tubes deteriorate the chiller functionality. You should watch out for algae, sludge, scale, and other contaminants likely to accumulate on the surface, especially on the waterside. Sometimes the water quality can affect the fouling and the type of system may lead to different fouling rates.
Follow manufacturer specifications for maintenance
Most manufacturers will recommend a thorough cleaning of tubes annually for the open system chiller. They also give a general cleaning recommendation for the evaporator which is typically 3 to 4 years after the last clean. However, you must undertake monthly inspections and log the finding to help determine an appropriate cleaning time.
Use appropriate cleaning methods
The common cleaning methods are mechanical and chemical. The mechanical method is ideal for dealing with mud, algae, sludge and dirt particles materials. You will have to open the water-box covers and brush the tubes and then flush clean water. The chemical cleaning process is for removing scale, and you need to call technicians for water-treatment suppliers to advice you on the proper chemical cleaner to use.…
