In Water Cooling Towers Counter flow cooling tower, Cross flow cooling tower, Constructional type cooling tower, Closed circuit cooling tower or Open Circuit Cooling Tower For almost all of them, there is a need for a high air flow through the fan or with natural attraction for excellent heat transfer. The unit used in this subject does not change in Turkish and English.
m³ / s: cubic meter / second. (Classification of the air per second in cubic meters)
m³ / min: cubic meters / minute. (Classification of air per minute in cubic meters.)
m³ / h: cubic meter / hour. (Classification of air passing per hour in cubic meters.)
In addition to these definitions, there are some abbreviations in English.
cmh: cubic meters per hour ( Classification of air passing per hour in cubic meters)
In particular, the air flow rate is very high in the tower is usually expressed in cubic meters / second.
For example :
Fan blades made of Pp (polypropylene) or Pag (polyemit) material
A fan designed at 750 rpm with 1450 diameters can supply 15,5 m3 / s air at 5,5 kW power.
Fan blades made of aluminum material
A fan designed at 750 rpm with 1450 diameters can supply 18 m3 / s air at 5,5 kW power.
