BRIEF DESCRIPTION OF AIR-CONDITIONING SYSTEM
It is proposed to provide Screw chilling machines to meet the air conditioning requirement
of all the air conditioned areas of Service building and Administrative building. Further, air-
conditioning requirement of Auditorium and canteen would be met with air-cooled
condensing machines. Other DCS/PLC based control rooms of auxiliary buildings would
be air-conditioned using split (non-Ductable) air conditioners. Dining hall in Administrative
building would be air-conditioned using Cassette (non-Ductable) air conditioners. Details of
major areas to be air conditioned and the equipments proposed to be provided are
elaborated in the following para.
