Did you know?
WebWe heard from an engineer years ago (but cannot find the source right now) that every ºC the air temperature is lower than the pool temperature, the evaporation rate increases 7%. That may seem small, until the air is 3 or 4º colder than the pool, and you have 21-28% more evaporation than the dehumidifier was designed to handle. WebEvaporation. Evaporation is the process in which a liquid changes to the gaseous state as the free surface, below its boiling point, through the transfer of energy. Evaporation is a cooling process- the latent heat of vapourisation (~585 cal/g of evaporated water) must be provided by the water body. Rate of evaporation depends on.
