RANCANG BANGUN MESIN MINI PENGKONDISIAN UDARA TIPE WATER COOLED CONDENSOR DENGAN PENGONTROLAN TEMPERATUR KABIN BERBASIS MIKROKONTROLER ARDUINO
Abstract
Abstract
This study is a design of a mini air conditioning type water cooled water prototype and perform-test using a variable in the form of an indoor air comfort between 22.8oC to 26.7oC. These prototype testing aims to examine the performance of the design results based on two conditions test. Firstly using the Arduino Uno microcontroller for controlling indoor air temperature, namely the DS18B20 temperature sensor and secondly without microcontroller. This research was conducted for one hour with five testing times, namely at 0 to 10 minutes, 11 to 20 minutes, 21 to 30 minutes, 31 to 40 minutes, 41 to 50 minutes and 51 to 60 minutes. The results showed by using microcontroller was produced energy consumption as compressor power with energy ranges from 247 watts to 264watt and when the minimum evaporator temperature is reached (8oC), the compressor of energy consumption has decreased from 70.22% to 93.29%. The same thing happened when the maximum evaporator temperature was reached (20oC), the energy consumption by compressor also decreased from 59.77% to 72.02%. While the results of testing without using an Arduino microcontroller, the energy consumption always tends to be constant at 10 to 60 minutes, where the average consecutive energy consumption varies from 267watt to 275watt for each evaporator temperature performance. Meanwhile from test results used Arduino microcontroller it provides savings in electrical energy consumption in the form of compressor power is 14.65 watts for every 10 minutes of testing. Also the results of known that microcontroller-based temperature control needs to be done so that the coefficient of performance of the machine can be kept constant and the compressor does not work continuously when the indoor air temperature is reached, in this case could be maintain the long-life of compressor.
