This paper presents the numerical simulation of an efficient ammonia-water single-stage absorption chiller integrating a new combined desorber, able to produce and purify refrigerant vapor. An experimental campaign was conducted on pilot plant by varying main operating parameters, namely temperatures external sources mass flow rate working fluid. Direct measures were analyzed indirect calculati...

The declining freshwater resources can be overcome using thermal desalination methods such as solar still. However, the productivity of a still is highly dependent on environment and design. In this study, an improvement passive with partially coated condensation cover thermoelectric cooling system was made. effect varying power (12 W 36 W) investigated compared reference under tropical weather...

An innovative biomass gasifier integrated plant was proposed for combined heating and power production in the current paper. The consists of an s-CO2 cycle, gasifier, combustion chamber, a domestic water heater purposes. system studied from different perspectives, i.e., energetic, exergetic, exergo-economic, economic, environmental (4E). For this purpose, simulation carried out by EES software;...

In this study, first-law, second-law, and exergo-economic investigations are accomplished to recover the waste heat of a two-shaft turbofan engine applying supercritical carbon dioxide Brayton cycle. The efficacy different operating parameters including inlet temperature turbine, pressure ratio compressor, Mach number on performance proposed system in terms energy exergy performance, destructio...

Major objectives of this study were to produce low-emitting wood pellet biofuel from selected agro-forest tree species, i.e., Kikar (Acacia nilotica), Oak (Quercus semicarpifolia), and Mesquite (Prosopis juliflora), grown in the southern part Khyber Pakhtunkhwa (KP) province Pakistan using indigenously developed technology (pelletizer machine). Primary raw material, such as sawdust was obtained...
