Chiller Man

Maintenance is a critical part of energy efficiency. Are you finding a growing awareness of maintenance strategies?

Unfortunately, I am not finding the awareness for maintenance or operational strategies for ‘green’ issues being addressed with the urgency and importance that they should be afforded. It is unfortunate that the majority of the end users feel that if they have a BMS, energy management or facility control system installed, they have achieved an acceptable ‘green’ solution. The fact of the matter is that a proactive recommissioning, predictive and preventative maintenance program on the chillers will save more money than most any other ‘green’ solution available.

The chillers account for the bulk of the energy consumption. Unless the chillers are, first and foremost, operating in peak condition, huge amounts of kWh and associated money is being wasted, which no control system can correct. The priority for district cooling, building owners, shopping malls or any industry or facility that has liquid chillers has to be proactive professional chiller services and maintenance being applied, so the kWh achieved and attendant money savings become the biggest contributor to the region’s sustainability goals.

We have introduced two energy-saving and/or water-saving solutions that save substantial quantities of water, energy and eliminate condenser chemicals.

What are your biggest opportunities and challenges at present?

Our biggest opportunities are in educating any and all facilities managers to understand the vast amounts of energy that chillers consume, and how much potential savings are available to them at no additional investment. US Chiller Services can achieve these savings with one of our custom-designed service technical support programs, without any capital investment, as it can be paid out of the operational budget.

In most, or all, instances we are lower in cost than our competitors. Without a doubt, the cost is less than an in-house service, and our savings will be realised immediately. Our biggest challenges are complacency, facilities thinking they are receiving good service on their chillers either outside or in-house and not realising they are not really getting what they deserve, and who are willing to go along consuming excessive energy and not really knowing they are doing so.

What is your outlook for the future?

I by no means can predict the future of the industry or the economy, and as the past year-and-a-half has proven, neither can the so-called experts. The global downturn caught everyone by surprise; I am sure the recovery will as well.
