A remarkable progress has recently been achieved in studies of thermodynamics and heat machines, with experiments probing down to micro and nano-scale systems such as the single Brownian particle [1], as well as the single atom [2]. However, despite several theoretical proposals [3, 4], implementation of heat machines in the fully quantum regime remains a challenge. We report on an experimental realization...
The outcomes of this groundbreaking synergetic study have been able to establish the viability of a sustainable, scalable and affordable cooling solution for an outdoor application in Lusail City, Doha, Qatar. The first segment of this study demonstrated the limitation of the proposed scheme as it was able to meet only 90% of the cooling demand There are few days in the year; when direct solar irradiation...
A Nnao adsorption solar power cooling generator unit is design, built, and operated under the climate of Mutah University. The adsorption solar power consists of the generator, condenser, vacuum pump, and evaporator (cold chamber). The activated carbon methanol is set as adsorption pair. The thermal impact of the modified paints on the collector performance by adding certain nano-materials to the...
Gas turbine-based CCHP system performance is strongly influenced by the ambient conditions. Gas turbine inlet air cooling technology improves gas turbine performance and its integrated CCHP system performance as well. Using the typical analytical characteristics of the system components, i.e. , small-sized gas turbine, single pressure HRSG and double-effect water/LiBr absorption chiller, this paper...
As a new absorption refrigeration system, NaSCN-NH3 diffusion absorption refrigeration system uses a solution of an inorganic salt compound as the absorbent, ammonia as the refrigerant. This paper presents some parameters that affecting on the performance of NaSCN-NH3 diffusion absorption refrigeration system. By comparing simulation and experimental data, the results show that the COP of NaSCN-NH...
ldquoDevelopment for advanced thermoelectric conversion systemsrdquo supported by the new energy and industrial technology development organization (NEDO) has been successfully completed as one of the Japanese national energy conservation projects. Three types of the cascaded thermoelectric modules operating up to 850 K in high electrode temperature and two types of Bi-Te thermoelectric modules operating...
