Anecdote:
geen zorgen over je haar. Dankzij de extreem fijne nevel en de directe verdamping kun je genieten van koelte zonder dat het voelt alsof je in de regen staat. En dames (of heren met volumineus haar) mogen gerust zijn: er is geen risico op kroezelend haar of vochtige lokken. De mist verdwijnt letterlijk in de lucht voordat hij je kapsel bereikt.
Heatsail chooses misting for cooling
How misting cools: evaporative cooling in action
-
Misting systems work through evaporative cooling. Water is atomized into fine droplets in the air, which then evaporate. This evaporation absorbs latent heat from the surroundings, resulting in a direct drop in air temperature. For every gram of water that evaporates, around 2.26 kJ of heat is removed — a powerful natural cooling method..
- Why nozzle size and pressure matter
At Heatsail, we use nozzles with a 0.15 mm orifice and a working pressure of 70 bar. This creates an ultra-fine mist with microdroplets smaller than 10 microns:
• Smaller droplets = faster, more complete evaporation
• High pressure = no wet surfaces, just refreshing air
• Optimal coverage without condensation or droplets
At lower pressures (<30 bar), the droplets are larger and:
• evaporate slower
• are more likely to land on skin or furniture
• cool the air less effectively - Potential temperature reduction
Cooling efficiency depends heavily on relative humidity:
Relative Humidity vs Typical Cooling
30–40% 7–10°C
50–60% 3–5°C
70%+ 1–2°C
In dry conditions, the difference between dry-bulb and wet-bulb temperatures can be surprisingly large.
