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 PLC/Microprocessor/ controller
integrated GIU 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.
