SUVARNABHUMI AIR CONDITIONING SYSTEM
BUILDING CONFIGURATION
The Terminal building requires to have large hall area without concrete
pole or with minimal concrete pole for passengers’ convenience. For maximum
passengers comfort with ease of traveling within the airport compound, the
building comprise of two sectors, the Terminal and Concourse building. The
Concourse building is for airplane connection to boarding bridges. The
Terminal building is for handling departure and arrival passengers.
 For energy saving purpose, the airconditioning will be provided only from
floor level to 3 or 4 meter above the floor since passengers will not stay higher
than 2 meters above the floor

Usage of direct sun light with minimal electrical lamps during day time.
Air conditioning will be provided only from floor level to 3 or 4 meter
above the floor to reduce the air conditioning load by means of
Stratification technique. This technique use Radiant Floor Cooling
together with Recirculated Air Cooling System.
Control intake fresh air for continual changing number of passengers.

Adjust Variable Chilled Water Volume for continual changing cooling
load.
Use Chilled Water Temperature Difference ( delta T ) larger than normal
conventional type which will require lesser pipe size and flow rate, thus
reduced the pump size and energy required.
Reduce make up water of Cooling Tower by way of water filter instead of
bleed-off
Reduce solar heat gain through glass by way of using Frit, a small
circular pad, spread evenly on glass which help reduce the Solar Factor

Reduce infrared radiation from ceiling and wall by way of applying LowE Infrared Hard Coating on ceiling and wall.
Reduce convective heat gain from electrical lamps since the heat gain will
be combined with hot air above stratification level which will cause no
effect to passengers.
Reduce radiation heat gain by way of using radiant floor cooling together
with conventional air conditioning system.

ABSORPTION CHILLERS at CENTRAL PLANT located within
Parking building next to the Terminal building. DCAP installed 4
ABSORPTION CHILLERS ( DOUBLE EFFECT TYPE ) on each
plant (EAST and WEST PLANT) and each absorption chiller has the
capacity of 2,100 TR (norminal) and can produce 706 m3/hr (196.11

By using natural gas as fuel to generate electricity and use
excess heat to produce hot steam as a requirment for absorbtion
chiller to produce chilled water for air conditioning purpose. This
technology will increase efficiency in generating electricity and
chilled water and will also reduce energy required.
