Development of a Cooling System Simulation Model using Thermoelectric Peltier based on Microcontroller

Abstract

The development of technology can be seen from the increasing number of industries that are standing and especially industries that produce air-conditioning machines such as Air Conditioner (AC), Air Cooler and Chiller. As the name implies, AC has a function to condition the air in a room so that it feels cool, comfortable, and healthy. In operation, AC requires electricity, and almost all of its main components require electricity so that the cost of using flow electricity is the benchmark in efforts to save energy. At the tool and system design stage, an overall tool design is carried out to form a miniature air-conditioning system using a Peltier Thermoelectric. The purpose of designing this tool is to produce a tool that functions to cool a room, so that the temperature in the room is cool and maintained, with the performance of Peltier TEC1-12706 and also heatsink as a channel for cold air through fans indoor and outdoor, and displaying temperature. In testing the system there is a slight difference from the measurements of the results with the component datasheet. On the results of the power test on the 12 V.10A adapter without load, the average output is 12.11 V, not pure at 12 V because the voltage displayed on the AVO meter has an average difference of 0.92%. Whereas in the measurement of power by load, that is, with an average load of 12.05V because the voltage displayed on the AVO meter has a difference and the voltage already has a load and has an average error of 0.41%. The existence of this error is because the current entering the adapter is also unstable.
