  In the world of industrial cooling, scroll air-cooled chillers are spearheading an energy-efficiency revolution. Among them, the newly launched 800kW chiller by   H.Stars Group   has quickly become a topic of industry discussion. But what qualifies as a “large-scale” unit in this field? Let’s decode the standards of industrial chiller classification from a technical perspective. 1. Understanding Chiller Size Classifications In the HVAC industry, the size of a chiller is defined by more than just its physical footprint. According to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers),  scroll air-cooled chillers  can be categorized by cooling capacity as follows (for reference): • Small Units: <200kW • Medium Units: 200–500kW • Large Units: >500kW This classification considers system integration, efficiency curves, and actual application environments—not just output power. International giants like Trane and Carrier follow s...
