|How to work out the size and type of fan required:
|In order to provide adequate ventilation for a given application, it is essential the
correct size, type and number of units are selected. Selection of the correct fan depends on two
principal factors: the performance and application.
|Determine which mounting arrangements meet your requirements
|Calculate the VOLUME of the room in cubic metres (m3) by multiplying the lenght x width x height.
|How many air changes (AC/H) are required.Work out how fast one complete ‘air change’ needs to be carried out under warm conditions (i.e the maximum you will ever need the fan to operate).If excess heat in a certain growing environment is a common problem, or there is a large volume of plants growing in a very restricted space you will need more air flow per hour than for a larger growing area which doesn’t suffer from too much heat build up with smaller plants.Growers commonly underestimate just how much ‘air exchange’ is required to remove excess heat and humidity, bring in fresh CO2 and generally create fresh air movement over all of the plant surfaces. As a comparison to greenhouse crops growing in full sunlight – one air change per minute or 60 air changes an hour are often aimed for with large, mature crops growing under warm, humid conditions. However, in a grow room situation, one complete air change obtained in 4-5 minutes is acceptable. Obviously this needs to be more frequent (one complete air change in 2-3 minutes) where lighting is creating a lot of extra heat to be removed or when a CO2 generator is being used.
|Use the following formula: Volume (m3) x AC/H = Airflow (m3/h)
|Select a fan that does the airflow you require.
