  Chiller System Commissioning Protocol: Operational Readiness & Performance Certification 1. Protocol Overview and System Categorization The commissioning of a chiller system is a strategic mandate designed to ensure long-term life-cycle efficiency, operational reliability, and the protection of capital-intensive HVAC assets. A structured commissioning process transitions the plant from a static installation to a dynamic, high-performance cooling system. This protocol addresses the two primary categories of chillers: those defined by heat rejection methods (Air-Cooled vs. Water-Cooled) and those defined by the refrigeration cycle (Vapor Compression vs. Absorption). Vapor Compression systems utilize mechanical compressors—ranging from small Scroll units and medium-to-large Screw units to very large, high-efficiency Centrifugal units—while Absorption systems leverage a heat source and a lithium bromide-water cycle. The selection between these types dictates the infrastructure re...
