A Comparative Analysis of a Solar Powered Dc Refrigerator and a Conventional Ac Powered Refrigerator
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 4
Abstract
This Paper Presents A Comparative Analysis Of A Solar Powered Dc Refrigerator (A Tertiary Education Trust Fund Sponsored Project 2016/2017, The Federal Polytechnic Bida, Niger State) And A Conventional Ac Powered Refrigerator. The Comparison Was Based On Current Consumption And Corresponding Cooling Effect Of Each Refrigerator Using A Multi-Meter And Lm35 Temperature Sensor Through A Liquid Crystal Display (Lcd) To Display The Temperature On Screen In Degree Celsius. The Dc Refrigerator Has A Compressor Rating Of 74w Having Same Litres Capacity Of 75l With The Ac Refrigerator Of 80w Compressor. The Multi-Meter Was Connected In Series With Each Load For Six Hours; The Current Was Measured And Recorded While The Lm35 Sensor Displays The Temperature. The Starting Current Of The Dc Refrigerator Was 5.68a While 3.8a Was Recorded For Ac Refrigerator, The Dc Refrigerator Was Operating On 12v And The Battery Went As Lower As 10.68v Before It Went Off While The Ac Refrigerator Was Supported With A Stabilizer To Step Up The Low Voltage From The Utility Company Which Was Too Low To Start The Unit And The Supply From The Utility Lasted For Just Six Hours. With The Same Volume Of Item In Both Refrigerators And Refrigerator Capacity, The Dc Unit Shows More Efficiency Since It Has A Smaller Compressor Made By Danfoss, And Even With Low Voltage The Unit Was Able To Operate With A Reasonable Cooling Effect. Its Reliability In Terms Of Power Supply Supersedes The Ac Unit. This Paper Has Demonstrated The Viability Of Using Dc Powered Refrigerator And The Need To Promote Its Usage Especially In Developing Countries Like Nigeria Were Continuous Power Supply Form Utility Is Far From Reality.
