Air- versus water-cooled chilled water plants

摘要

As a consulting engineer, knowing when to design an air-cooled chilled water plant or a water-cooled chilled water plant can be a challenge. While the systems are similar, they have fundamental differences that will address unique project goals. This article will explain the components of each plant and present clear guidelines for optimized use of both plants, depending on the building type, size and client goals. This article will review the advantages and disadvantages of each system bases on size, noise control, cost and efficiencies. The primary argument is that in most cases water-cooled chilled water plants provide the most long-term benefits in terms of energy and cost savings, despite the higher upfront costs.
