वेंटिलेशन (en. Ventilation)

EESL has undertaken a retrofit of its office air-conditioning and ventilation system.

They commissioned a group of their best scientists to investigate, and what they found was that all these tape drives were located near ventilation ducts.

Building system design HVAC (heating ventilation and air conditioning), lighting, electrical, and water heating.

But let's first look at how the ventilation works.

Ventilation grids must be kept open.

The probability of transmission from one person to another depends upon several factors, including the number of infectious droplets expelled by the carrier, the effectiveness of ventilation, the duration of exposure, the virulence of the M. tuberculosis strain, the level of immunity in the uninfected person, and others.

They are necessary for ventilation.
