Heat rejection inside industrial cooling towers is governed by two simultaneous thermodynamic mechanisms: convective sensible heat transfer driven by the temperature differential between water and air ($Q_{sensible} = \dot{m}_{air} \cdot C_p \cdot \Delta T$), and latent heat transfer governed by phase change. As water transitions from liquid to vapor, every kilogram of evaporated water absorbs approximately $2400 \text{ kJ/kg}$ ($h_{fg}$) of latent heat of vaporization from the process stream. While sensible transfer plays a secondary role, latent heat transfer accounts for 75% to 85% of the tower's total thermal rejection capacity. At Ucsan Makina, our cooling tower designs maximize this phase-change surface area through precision wet-deck fills and balanced air-to-water flow dynamics.
