Cooling Energy, Water & Sustainability

Energy intensity, part-load performance, water use, refrigerants, hybrid systems, KPIs and optimization.

Evaluate chillers, pumps, fans, towers and controls as one system.

Use energy per unit of delivered cooling to compare operating periods.

Why chillers, pumps and fans spend much of their lives away from full load.

Makeup, blowdown, drift and reuse in evaporative heat-rejection systems.

Compare energy, water, climate and maintenance implications.

Electricity use and refrigerant leakage as separate environmental factors.

Why environmental rules and equipment technology are changing refrigerant choices.

Combine dry and evaporative heat rejection to balance water and energy use.

Temperature approach, energy intensity, water use, availability and fouling indicators.

Coordinate setpoints, equipment staging and heat rejection rather than tuning components independently.

Liquid cooling, advanced controls, heat recovery, lower-impact refrigerants and higher-density thermal loads.
