Sensible vs Latent Heat
Why cooling a material and changing its phase are different thermal duties.
What this topic covers
Why cooling a material and changing its phase are different thermal duties.
Core thermal ideas
Sensible heat changes temperature without changing phase.
Latent heat is absorbed or released during a phase change, such as evaporation or condensation.
Cooling towers and refrigeration systems rely heavily on phase-change behaviour, while many closed water loops primarily transport sensible heat.
System tradeoffs
Temperature difference drives heat transfer, while flow, area, fouling and thermal resistance determine how easily heat can move.
What to monitor
Water chemistry, refrigerants and process fluids require site-specific safety and environmental controls.
Lifecycle perspective
A lifecycle view includes energy, water, maintenance, fouling, reliability and future load—not only nameplate cooling capacity.
