There are FOUR solution sets available for Chiller Optimization:

♦  Water Cooled – Cooling Tower Optimization
♦  Water Cooled – AI Optimization Software
♦  Air Cooled – Convert to Variable Speed Comp.
♦  Air Cooled – Pre-Cooled with Water Mist

If a building’s HVAC system was a body, the chiller plant would usually be considered the “heart”.  Not only is the chiller plant the main source of cooling, but its power requirements make up a large amount of a building’s energy consumption.

This makes chiller optimization critical to achieving better building energy performance.

A primary challenge with achieving chiller optimization is recognizing that your chiller plant is very likely not operating at it’s designed ‘temperature differential’, which is the temperature difference between the chilled water supply and the chilled water return – called the “Delta T.”  It is not uncommon to find chiller plants operating at far less than optimal levels (at a lower Delta T). 

This can be caused many factors, including how the chiller equipment is controlled or how the air handlers, fan coils, etc. are operating.

The key to chiller optimization starts with the operation of the chillers and chilled water pumps.  Variable-primary chilled water system is a more efficient setup because only one set of pumps is used to move water through the chillers and the building systems.

♦  Lower Electricity and Maintenance Costs:   Advanced chiller optimization is commonly recognized as a proven and reliable way for buildings and facilities to reduce the amount of money they are paying to run and operate their HVAC and refrigeration systems.

Most existing systems waste money cooling a building (as much as one out of every three dollars spent). Chiller optimization can remove that inefficiency, increasing system capacity and delivering long-term energy savings.

Clients typically see electric savings from 10% to 40%, and wear and tear on chiller equipment – motors, pumps, compressors, fans – are dramatically reduced, extending their lifespan.

♦  Improved Occupant Comfort:  Buildings and facilities of all sizes are under pressure to keep energy costs low while still delivering occupant comfort.

Advanced chiller optimization allows building and facility operators to regulate and maintain the right temperature with incredible precision. In some cases, clients have reported as high as a 90% reduction in comfort complaints.

And with the decrease in hot and cold calls, building and facility support staff have more time available for preventative maintenance activities.

♦  Environmental Sustainability:  Advanced chiller optimization has been a sensible and proven path to helping our clients achieve their environmental objectives – not only through reductions in energy consumption, but with the capacity to effectively measure and track energy consumption trends and proactively anticipated potential demand requirements.
