| dc.description.abstract | Air conditioning systems commonly used today is the Air Conditioning (AC), in
which the use ofchemical substances such as freon gas or environmentally
unfriendly substances refrigran can damage the ozone layer in the earth's
atmosphere that have an impact on global warming. Therefore, needed
alternative/new breakthrough of the cooling system that does not use chemicals
that are environmentally friendly using cooling module Thermo Electric Cooler
(TEC) which utilizes the cold side of the Thermo Electric Cooler (TEC). Thermo
Electric Cooler (TEC) when the supply voltage of the DC (direct current) one side
will be hot, while the other side would be cool, to maximize the cooling process,
the hot side Thermo Electric Cooler (TEC) should be lowered as low as possible
by using a fan, heat sink and thermal paste (thermal grease). A refrigerated room
dimensions Length 20cm, width 20 cm and 20 cm High. Number of Thermo
Electric Cooler (TEC) 8 pieces of voltage 12 volt, 6 Ampere current, dimensions
40 x 40 mm and 4 mm thick. Thermo Electric Cooler (TEC) are arranged in
parallel and electricity are arranged in series. Number of fan 3 pieces (2 pieces fan
hot side and 1 fan cool side) and components of air conditioning systems include
power supply, Thermo Electric Cooler (TEC), heat sink, fan, Junction terminal,
Sterofoam/isolator and Thermal paste (thermal grease). This cooling system
requires power 277.2 Watt. Work on this | en_US |
