Cost Control Techniques for Cooling System Maintenance

This seminar will share practical methods for lowering the cost of cooling system maintenance, including daily maintenance, spare parts selection, and energy-saving technology application.By optimizing cooling system maintenance procedures, the company has reduced the failure rate and extended the life of equipment, saving companies money and achieving efficient operations.

Why is the cost of maintaining the cooling system so high?

Many factory and machine room administrators have found that their cooling system maintenance costs are always higher than budgeted.The problem may be two-fold: one is that the equipment has been overused and worn out; the other is that the maintenance method is insufficiently scientific, for example, by relying too much on the passive "fix-it-when-it-breaks" mode.If they want to control costs, they need to start with preventive maintenance and precise management.

The secret to saving money on daily maintenance.

Don't neglect basic cleaning.

Problems such as dust accumulating on heat sinks and oil stains on fan blades may seem trivial, but in fact they can cause equipment to consume 10 % more electricity.Cleaning the heat dissipation parts with a soft-bristled brush for ten minutes a week can reduce energy consumption and wear.

Check the coolant regularly.

If the coolant is too dirty or contains too many impurities, it can cause the pipes to become clogged or corroded.It is recommended that the pH value and impurity content be checked once a quarter so that the fluid can be replaced in a timely fashion.Purchasing the paper is 80 % cheaper than having someone come to your home to perform the test, and it is also much easier to use.

The door to spare parts management.

Selecting the right replacement model.

The original brand filter costs NT $ 200, but if you try a third-party brand, the price can be cut in half.The main points to look for are whether the filtration and pressure ratings are sufficient. Don ’ t be fooled by the claim that the parts are “ specially designed.

Establish a parts life file.

For each piece of equipment, a Microsoft Excel spreadsheet is created to record the time of replacement of easily damaged parts, such as fan bearings and seals.After learning the pattern of wear, they can make large purchases of spare parts before the machines break down, saving 30 % in freight costs over emergency orders.

The long-term benefits of energy conservation.

Install a frequency controller.

Old-fashioned evaporative cooling towers are very power-hungry when run at full speed.Installing a variable frequency drive (VFD) to adjust the rotation speed according to the temperature has produced instant results in terms of energy savings.One food factory saved NT $ 12,000 per month in electricity costs after retrofitting, and recouped the cost of the retrofit in six months.

Make use of heat recovery technology.

Connecting the boiler and the workers 'bathrooms to the cooling system's waste heat is like getting free energy.Although the start-up costs are NT $ 50,000-80,000, the returns in the first two years often exceed expectations.

Cultivate the team's cost consciousness.

The company also provides a monthly training session for operators to teach them how to recognize early signs of trouble, such as unusual noises or vibrations.Early detection can reduce losses by 70 % over the costs of repair.Employees are rewarded for proposing energy-saving measures. There are many examples of employees being rewarded NT $ 200 for a measure that saves the company NT $ 10,000.
