The trend of consumption of hydrocarbon fuels in Indonesia, which is increasing every year, is not accompanied by the amount of production, which is decreasing. Alternative fuels to reduce dependence on hydrocarbon fuels. One form of alternative fuel is b... see more

Thermal efficiency in the ceramic firing process is crucial to reducing energy consumption, emissions of gaseous pollutants and the cost of production. This study, reports on the determination of thermal efficiencies of a traditional 3m x 28m x 2.7m cross... see more

This research work deals with a feasible non-regenerative thermal cycle, composed by two pairs of closed polytropic-isochoric transformations implemented by means of a double acting reciprocating cylinder which differs basically from the conventional Carn... see more

The KB-5 high pressure gas burners were popularly and widely used in Thailand. This research was aimed to study the influence of four significant parameters, namely degrees of outer and inner ports and the number of outer and inner ports of high pressure ... see more

This work is about assessment of the single-ended evacuated tubular solar thermal collectors which are widely used in solar heating applications. Exchange and transfer of heat are accomplished by a thermosyphon process. The flow pattern of the working flu... see more

Thermal efficiency of borehole heat exchangers (BHE) is of crucial importance for the design and optimization of ground source heat pump (GSHP) system. This paper investigates thermal efficiency of a BHE with three drillhole diameters: 121 mm, 165 mm and ... see more

We investigated the synergetic effect between light-emitting diode (LED) lighting efficiency and building energy savings in heating and cooling using an alternative thermal operating system (ATOS) of indoor LED lighting integrated with the ventilation sys... see more

The present research proposes two different studies to analyse the thermal behaviour of a building in the city of Madrid, located in Apolo-nio Morales street, 29. The first case analyses how the thermoactivated floor of heterogeneous section works. The se... see more

The distribution of costs for electricity and heat production is accomplished by a number of fairly conditional methods. Cost analysis and allocation must be carried out on the basis of objective technical and economic criteria. The application of a metho... see more
