Minimising the risks and costs of energy efficiency

In today’s competitive business environment, development minimising operating cost and mitigating risk, while keeping focus on energy-efficiency and delivering the cooling a business needs to succeed, is important.

During winter, the demands on the chiller plant system are significantly lower, creating the perfect time for a thorough review of the system.

Proactive maintenance today can avoid costly interruptions or downtime when temperatures rise and cooling is needed.

In-depth reviews will also allow you to consider ways in which your cooling system could be enhanced to reduce operating costs and increase performance.

Proactive plan

One good practice that helps maximise investment is to have a proactive heating, ventilation and air conditioning maintenance plan customised to a particular building’s needs.

A combination of regular and preventive maintenance helps optimise system performance and reliability. A proactive maintenance plan should take into account a building’s unique application, load signature and system requirements.

Deferring regular maintenance to save money is a poor practice and will likely cost your organisation more in the long term.

Delaying the maintenance of complex building systems, which in most instances goes against the very recommendations of the OEM, is a bigger mistake than, say, skipping an oil change on
a car. Deferring maintenance places crucial assets at risk for more extensive damages and costlier repairs in the future.

If you are looking to reduce costs, consult your maintenance records and take into account OEM recommendations to ensure that current HVAC systems are up-to-date to avoid the potentially larger and unbudgeted costs associated with significant repairs or new equipment.

Check your oil

Oil analysis can detect minor problems before they become major. Regular oil analysis helps increase compressor life. By observing changes in the signature, conditions like bearing wear, shaft imbalance and degrading rotor tolerances can be identified before they cause a breakdown.

Internal and external corrosion, deposits, wear or cracking can also be detected by testing the heat exchanger tubes. Proactive maintenance can prevent major damage. System performance and cost efficiency can be optimised by upgrading your heat exchangers. Regular condition checks will indicate the best course of action.

You can get real-time status and performance of your HVAC system from health checks performed by expert OEM service teams. These checks assess the system’s condition and offer recommendations of measures for reliable and efficient operation.

One good practice is to have a customised service solution which is suited to the needs of the building and the business.
