In this study, the first and the second laws of thermodynamics (exergetic analysis) are used to analyse the performance of a single stage ammonia-water absorption cooling system operating under different working conditions. In this analysis, the performance of the system is simulated under various operating temperatures: the condenser and absorber (30 and 40°C), evaporator (-10°C, 0°C and +10°C...

The best way to meet the European Union's energy awareness goals is use a heat pump/refrigerator that requires renewable or waste operate. Absorption machines are often powered by heat. This article, it was examined how absorption chillers can be optimized for cooling. increasing minima of cooling exergy efficiency chillers. effects this increase on quantitative and qualitative indicators were ...

In this paper, the exergoeconomic analysis was conducted to an existing ultra-supercritical coal-fired power plant in China to understand the cost-formation process, to evaluate the economic performance of each component and to find possible solutions for more cost-effective designs. The total revenue requirement (TRR) and the specific exergy costing (SPECO) methods were applied for economic an...

This paper proposes the first application of a split-range control technique on concentrating solar collector to improve an absorption plant production. Solar plants have power availability in phase with cooling demand under design conditions. Thus, it is powerful technology context renewable energy and efficiency. These need systems cope irradiance intermittency, reject irradiation disturbance...

The exploitation of nanofluids is the most noteworthy way to make better rate heat transfer in solar collectors. Moreover, recently utilizing thermoelectric generators are widely studied direct conversion into electricity. objective present study deal with a novel multigeneration system that includes nanofluid-based parabolic trough collector integrated quadruple effect absorption refrigeration...

In order to achieve both power and cooling supply for users, a new combined cooling and power system using ammonia–water mixture is proposed to utilizing low grade heat sources, such as industrial waste heat, solar energy and geothermal energy. The proposed system combines a Kalina cycle and an ammonia–water absorption refrigeration cycle, in which the ammonia–water turbine exhaust is delivered...
