Daily water usage per 100kW load?

Question

Accepted Answer

Short answer Under a 100kW load running 24 hours: a closed-circuit cooling tower consumes roughly 4.0–4.5 tons of water per day, while a dry cooler supplemented with an evaporation pad consumes roughly 0.8–1.2 tons per day. Closed-circuit tower: ~4.0–4.5 t/day Dry cooler + evap pad: ~0.8–1.2 t/day Figures at 100kW continuous load Measured over 24h operation Water consumption comparison (100kW load, 24h) Heat rejection optionApproximate daily water use Closed-circuit cooling tower≈ 4.0 – 4.5 tons/day Dry cooler + evaporation pad≈ 0.8 – 1.2 tons/day Why the two options differ so much Evaporative assist is what consumes water — the drier the route, the lower the use. Evaporation is the water cost. Both figures are driven by how much water is evaporated to reject heat. Dry coolers minimize water use because most heat leaves as sensible heat through the coil, not as vapor. Water vs efficiency is a trade. The lower-water option must still hold inlet temperature at your wet-bulb — see the 38°C+ cooling FAQ. The loop that carries heat out to rejection. Dry tower route for low-water operation.
