Fresh air ventilation systems, extract systems, cascading pressure systems (eg. hospital operating theatres), displacement ventilation systems.
The fresh air system is designed to enhance the heating and cooling systems. In most instances we are able to build in heat recovery systems, or incorporate some free cooling via the fresh air system.
The hospital ventilation system requires precision with design, to ensure the correct room pressures. Only in this way can we be certain that the airflow is from clean areas to dirty areas, and not vice versa.
Displacement ventilation systems incorporate heating and cooling, and are designed to be able to introduce a high quantity of air into a space without causing a draft.
Extract systems can be a simple toilet extract fan, a commercial extract system, or an industrial or medical system requiring high efflux velocities to ensure that the vitiated air is projected high into the atmosphere.
