During the Industrial Revolution in the 18th and 19th centuries, ventilation and cooling became increasingly important due to the introduction of industrial machinery and large-scale production processes. Factories and mechanical workshops had to manage the heat and humidity produced by machines and manufacturing processes. …

The results indicate that plant factories (i.e. vertical indoor farming systems) are more energy-intensive than greenhouses in all climates. The specific energy consumption of ventilated OGHs is significantly lower than the other two systems, even in more extreme climate, although at a higher level of water consumption.

How Local Exhaust Ventilation Works. LEV systems function by creating a flow of air at the source of emission. This airflow captures contaminants and transports them through ducting to filtration units, effectively removing them from the workplace atmosphere. The efficiency of an LEV system depends on the design of its components and the proper ...
