Kolaborasi Kipas Angin dengan Elemen Peltier untuk Mendapatkan Udara Sejuk Menggunakan Mikrokontroller Atmega8535

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
