Experimental Study of Wind Turbine Power Generation Utilizing Discharged Air of Air Conditioner Blower

Abstract

The world's energy demand has become unbridled in the past years. The increasing demand for conventional energy sources (fossil fuels, nuclear) became under tremendous pressure which is resulting from continuous use of it. This continuous use leads to a scarcity of fossil fuels. This has sparked widespread research in the field of unconventional energy sources such as hydro energy, wind energy and thermal energy. Wind can be used as a renewable energy to generate the electrical energy. In the current study, the wind of the air conditioning exhaust has been utilized as a renewable energy to generate the electrical energy. The wind speed is relatively stable every time, this feature encourages the use of air conditioning exhaust. Different wind speed for three types of air conditioning 1HP, 2HP and 3HP was investigated experimentally. The maximum wind speed with 3 HP was 7.1 m/s and 7.2 m/s with anemometer attached to the blower of air conditioner at distance 24 cm on the left and right of the middle of air conditioner blower, respectively. The wind turbine has the ability to convert the wind energy of blower into electrical energy. The wind turbine, Savonius type L, was connected together with direct current (DC) generator and alternating current (AC) generator and fixed inside the Perspex duct. The Perspex duct was connected to the air conditioning exhaust. It was obtained the AC generator can generate voltage 35 V, current 0.51 A and output power14.28 W with adopting 3 HP capacity air conditioner. While the DC generator can generate 46 V, current 0.32 A and output power 14.72 W with adopting 3 HP capacity air conditioner. The generated electrical energy can be used for operating small devices that is need low amount voltage or to turn on the LED lights.

Investigation of Blade Modifications to Enhance Savonius Water Turbine Performance Through Vertical Pipe Flow

“…This system is suitable for application in hinterland areas that don't have an electric supply network. The Savonius turbine is a type of pico hydro turbine which is a solution for electricity supply, supported by its simple and low-cost construction 26) . The modified Savonius turbine with the variations of additional blades between the conventional form was conducted by Herlambang.…”

“…The Savonius turbine configuration's shape influences fluid direction flow through the blades 24,25) . Therefore, modifying the conventional Savonius turbine in the form of Type L can increase its performance because it is lighter than the conventional form 26) . Based on turbine weight, M. Al-Ghriybah's study investigates the thickness of the turbine base material, which shows that the thickness also increases the turbine weight, so the generated performance increases up to 40% 27) .…”

Robust Optimization Framework for Economic Dispatch of DER and BES Based Micro Grid Considering a Voltage Dependent Load

“…For development in the power sector, different methods are being utilized such as electric utility with proper channel, rule regulation decentralization and proper distribution of the power with dynamically changing control system in the electricity market. Distributed energy resources are used for power generation using the different techniques like as micro-turbine, fuel cell, photo voltaic units, wind turbine 1) , diesel engines gas turbines 2) and storage technologies like flywheel, compressed air energy storage (CAES),Super conducting magnet energy (SMES), super capacitors and batteries. At present, the renewable energybased DG is rapidly integrated into AND hence DERs have become an integral component of the system.…”

A Mini Review: Wave Energy Converters Technology, Potential Applications and Current Research in Indonesia

“…Wave energy has emerged as a renewable energy source 1) , besides solar [2][3][4][5] , wind 6,7) , biomass [8][9][10][11] , and geothermal 12,13) , which already developed earlier, due to the energy crisis and environmental concerns 14,15) . One of the many benefits of wave energy is the percentage of power generation.…”
