Once user safety has been guaranteed, a fume hood in a properly run laboratory project must incorporate the aforementioned requirements into the climate control of the room or building. In this way there can be a reduction in the average air usage and environmental impact when exhausting it outside. To do this, the project must take into account:
• The appropriate laboratory ventilation requirements for the work its users are carrying out. Standard DIN 1946 recommends a chemical laboratory to renew 25 m³ of air per m² of laboratory space per hour.
• The amount of fume hoods per laboratory.
• The type of work carried out and the products used.
For a fume hood to properly carry out its function we must guarantee an exhaust differential in respect to the air movement in the laboratory. We must also take into consideration the physical conditions of the work itself as well as the generation of condensation through the absorption of acids or variations in temperature and humidity.
Average air usage can also be reduced to attain greater savings.
The right air management is consequence of its responsible usage by the user, the use of airflow adjustment systems and an automatic closing feature on the fume hood:
Therefore the complete air management system of Flores Valles fume hoods consists of:
By using all these systems we can attain significant energy savings.
