Meja TPP (2X660 MW)  
1.0  
SCOPE OF WORK  
The broad scope of work includes design, engineering, manufacture, testing at  
works, delivery and storage at site, erection, testing and commissioning of  
following:  
a) All air-conditioning equipments for office areas in Service Building,  
Administrative Building, Auditorium Building, Canteen Building and other  
PLC/Microprocessor/ controller integrated GIU based control rooms.

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.  
2.1  
A/C Plant for Service building.  
2.1.1 The A/C system would comprise of:  
i)  
2 X 165 TR capacity screw compression type chilling machine.  
Two (02) Nos. of primary chilled water pumps.  
ii)  
iii) Two (02) Nos. of variable frequency driven (VFD) Secondary chilled water  
pumps.  
iv) Two (02) Nos. of condenser water pumps.  
v)  
Two (02) Nos. of variable frequency driven (VFD) cooling towers.  
vi) Nine (09) nos. of variable frequency driven (VFD) air handling units (AHUs)
