Aspirator and ventilator

Air aspiration fan (aspirator) and supply fan (ventilator) (Figure.15) are the two main component in realizing air circulation in the space during air conditioning process. Aspirator sucks the room air via exhaust air duct and diverts it to the exhaust and mixing dampers according to the selected ventilation MOD while ventilator pushes the conditioned air into the room via supply duct. Both fans are driven synchronously by frequency controlled electric motors fed through motor starters. These fans can either operated manually or automatically by means of local or remote-control panels. It is usually operated in automatic MOD according to set values, indoor and outdoor weather conditions, energy saving and operating principles.
