Air- or Water-cooled Chiller Choices

Factors That Drive Chiller Choice

Deciding which chiller is best suited for a building is an essential step in any project. For mission-critical cooling, however, it’s a key factor to success.

Data centers, hospitals and manufacturing facilities typically have 24/7 operation cycles – and that means the factors that determine which chiller to use are essential.

Seemant Sharma, Director of Products and Distribution at Johnson Controls, shares insights on how to determine which chiller to use in this article published in ASHRAE Journal. Considerations such as power cost, water cost, weather and load profile all play a big factor. Sharma explains:

“…we posited initial capital costs, annual operating costs and a combination of both, along with the total cost of ownership (TCO) – all of which are typical deciding factors in equipment selection. Sensitivity to these factors influence different decisions based on capital or financing available to the building owner. Of course, many technical, commercial, compliance and site-specific factors can also influence the choice by eliminating either option as a non-starter.”

The article goes on to discuss these factors and key findings between sample chiller locations across the world.

Determining the ideal chiller for your application requires careful consideration of total cost of ownership, among other factors.
