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 Canteen would be met with air-cooled con
densing 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 150 TR capacity screw compression type chilling machine.
(ii) Two (02) Nos. of primary chilled water pumps.
(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) Five (09) nos. of variable frequency driven (VFD) air handling units (AHUs)
(vii) Interconnecting piping, duct work, insulation, cabling, PLC/Microprocessor
based control panel, instrumentation, etc.
2.2 A/C Plant for Administrative building.
2.2.1 The A/C system would comprise of:
(i) 2 X 150 TR capacity screw compression type chilling machine.
(ii) Two (02) Nos. of primary chilled water pumps.
(iii) Two (02) Nos. of variable frequency driven (VFD) Secondary chilled water
pumps
(iv) Two (02) Nos. condenser water pumps.
(v) Two (02) Nos. of variable frequency driven (VFD) cooling towers.
(vi) Eight (09) nos. of variable frequency driven (VFD) air handling units (AHUs)
Interconnecting piping, duct work, insulation, cabling, PLC/Microprocessor based
control panel, instrumentation, etc.
2.4 AC Plant for Canteen.
2.4.1 The AC system would comprise of
(i) 2 x 30 TR capacity air cooled type condensing machine.
(ii) Two (02) Nos. of variable frequency driven (VFD) air handling units (AHUs)
(iii) Interconnecting piping, duct work, insulation, cabling, PLC/ Microprocessor /
Controller
integrated GIU based control panel, instrumentation, etc.
2.5 Non-Ductable Split Air-Conditioners.
2.5.1 AC plant control room in Administrative building and Service building.
(i) 8 x 3 TR Non Ductable (Split).
2.5.2 Dining hall in Administrative building.
(i) 2 x 4 TR Non - Ductable Cassette
2.6 Mechanical ventilation system consist of Supply/Exhaust/roof extractor fans for ventilation of
Permanent Store/ Service Building/ Administrative Buildings /Canteen Buildings /etc. shall be
provided.
Detailed scope of work shall be as per specifications and scope defined in Bidding Document No. CS-
9562-147A-2 for Air conditioning system package for Auxiliary Buildings for Tanda Thermal Power
Project Stage-II (2x660 MW).
