Free Cooling and Economizers
Use favourable outdoor conditions to reduce mechanical refrigeration demand.
Safety boundary: this page is conceptual. It does not provide refrigerant charging/recovery steps, chemical water-treatment recipes, pressure-system procedures, electrical work, machine settings or hazardous maintenance instructions.
What this topic covers
Use favourable outdoor conditions to reduce mechanical refrigeration demand.
Core thermal ideas
Air-side or water-side economizer concepts use cool ambient conditions when available.
Climate, process temperature and contamination constraints determine potential operating hours.
Controls must transition between modes without compromising required cooling.
System tradeoffs
Chiller performance depends on evaporating and condensing conditions, exchanger cleanliness and auxiliary equipment.
What to monitor
Refrigerants are regulated and application-specific; service and charging procedures are outside this site's scope.
Lifecycle perspective
Plant optimization includes chillers, pumps, towers or condenser fans and control sequencing.
