Abstract

The availability of petroleum which continues to decrease and the level of public consumption which is always increasing are serious problems today. Renewable energy needs to be researched on an ongoing basis to anticipate the availability problems above. Proton Exchange Membrane Fuel Cell (PEMFC) is an environmentally friendly source of electrical energy because it only requires hydrogen and oxygen as raw materials and water as a result of the reaction. This study will discuss the PEMFC flow field plate because this component dominates the weight and cost of manufacture. Research on flow field plate PEMFC with wave rectangular cross-section is necessary to develop the PEMFC concept with better performance results. This study aims to determine the effect of the wavy cross-section shape on the distribution of channel average speed, channel outlet speed, inlet pressure, channel average pressure, and channel outlet pressure. This study uses a computational fluid dynamic (CFD) method using SolidWorks flow simulation software. This study provides an overview of the serpentine type of flow field plate with a wave rectangular and rectangular cross-section. The wave rectangular cross-section has a higher average velocity, outlet velocity, inlet pressure, and pressure than the rectangular cross-section. This is what will make PEMFC performance higher. The wave rectangular cross-section has nearly the same number of outlet pressures as the rectangular cross-section. Possible development of this research is the creation of simulation software to calculate other parameters that affect PEMFC performance.

Abstract

This paper focuses on the calculation of sizing ducting based on cooling load requirements the main ducting of office building following regulation airspeed requirements using American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) and Computational Fluid Dynamics (CFD) simulations. The purpose of this research is to validate the airspeed and turbulence that occurs in the main ducting between manual calculations and CFD simulations. From the calculation, the cooling load requirement is 58.22 kW, for the cooling process an air flowrate of 7117 L/s is needed which is designed to pass through the main ducting in rectangular shape. The main ducting size uses 1200 mm x 500 mm at a speed of 12.7 m/s according to ASHRAE. Autodesk Inventor software is used for ducting modeling and Autodesk CFD is used for airflow simulation. CFD simulations are performed by applying boundary conditions and input parameters. The results showed that the velocity of the ducting design was suitable at 12.7 m/s with laminar flow. The ducting geometry must be designed aerodynamically to reduce the pressure drop which can cause the speed to increase so that it is outside the required limits. Thus, the CFD simulation results have verified the validity of manual calculations.

Abstract

The electricity is very important to support activities in office building .The equipment like AC ( Air conditioning ) needs more electricity to be operated. The is almost 60%  is use to support this system (AC). This percentage describe that air condition system is an equipment that needs more electricity in the office and its become inefficiency in using electricity. To take overcome for this problem we need to efficiency in using energy. One of the method that now used to efficient that energy is called “ energy conversation” This method is using to saving the energy There is one thing that must be done in this activity which is “ energy audit “. Audit energy is one of method calculate IKE (  Intension Consumption  Energy) at on the building.The first preliminary audit shown that more energy, which 60% is use to operated the air conditioning (AC) system and 30% to operate lighting system. IKE for the lighting system is still below from maximum standard  which is 15 watt/m²The opportunity of saving energy on audit energy in AC system is done by cleaning up consist of : cleaning up filter, propeller corner fin of the evaporator, and the grill of in door unit.
