Abstract

The Southeast Sumatra block produces oil and gas. Natural gas production of 15,300 MSCF is used as fuel for turbine generators to generate 38 MW of electrical energy, while the rest is used as business products. The application of the solar-wind system can reduce the load on the turbine generator so that gas fuel consumption is also reduced. Five platforms have areas that can be utilized for a solar-wind system. This study aims to determine the amount of gas fuel consumption that can be reduced by the solarwind system application. The method is simulation using the HOMER software to determine the amount of electrical energy that can be supplied and the costs required by the solar-wind system. The components used are found in the HOMER software and on the market. The simulation results show that the off-grid solar-wind system can provide electricity supply of 50,235 kWh per year and reduce gas fuel consumption by 20,094 MSCF per year. The on-grid solar-wind system can provide electricity supply of up to 81,230 kWh per year and reducing the use of gas fuel by 32,492 MSCF per year. The off-grid solar-wind system will increase gas sales by $132,620 per year with NPV>0 and ROI 21%, while the on-grid system will increase gas sales by $214,447 per year with NPV>0 and ROI 57%. Both models of solar-wind systems have positive economic values so that they are feasible to implement. [ABSTRACT FROM AUTHOR]

Abstract

The use of commonly used vapor compression cycle cold storage in fishing vessel is facing limitations to be widely applied in Indonesian fishermen since it consumes more energy and requires large space. Thermoelectric refrigerator is believed to be a promising option due to its simple design and low energy requirement. However, the Coefficient of Performance (CoP) of the system in current development is relatively low. Although many researches have been conducted to increase the CoP of the system But there is still lack of studies focused on effects of the important variables to cold storage performance. The present study aimed to investigate the effect of input voltage on thermoelectric cold storage chamber temperature in the form of transient behaviors. As a result, it was found that the increase of input voltage significantly affected the cooling performance, although in 6 V input voltage, the result is only a bit lower than 12 V with much lower energy use. In addition, the time needed to get steady state in 12 V was the fastest compared to the other input voltages. Those results can be used as design consideration of a portable thermoelectric cold storage. [ABSTRACT FROM AUTHOR]

Abstract

A performance analysis based on exergetic performance coefficient (EPC) criterion was carried out for a dualevaporator vapor compression refrigeration system. The influence of the condensing and evaporating temperature on the EPC, the coefficient of performance (COP), the second law efficiency and the destruction of exergy will be presented. It is found that the evaporating and condensing temperatures have strong effects on EPC in the system. Condensing temperature increases will decrease EPC, COP, and second law efficiency, while evaporating temperature increases will increase the EPC, COP, and second law efficiency. The EPC increases and the total exergy destruction decreases with decreasing temperature difference between the evaporator and refrigerated space and between the condenser and ambient temperature. The EPC can be used for selection of optimal design parameters and the procedures given in this paper for exergy analysis of a dual evaporator vapor compression refrigeration systems has been applied to actual systems.
