Solar heating and cooling (SHC) systems are currently attracting attention, especially in times of increasing energy prices supply crises. In lower prices, absorption SHC were not competitive to compression supported by photovoltaic (PV) modules due the high investment costs total efficiency. This paper aims discuss current changes terms feasibility application a small system mild Mediterranean...

The dairy industry uses a number of energy intensive thermal processes like cooling, heating and cleaning that require electrical energy. Those use temperatures between 4 °C 200 could be potentially powered using solar but one the main challenges is complexity selection integration components used for system such as collectors, cooling equipment. with temperature requirements 300 400 are mainly...

Sustainable greenhouses have gained relevance in recent years due to their potential reduce the carbon footprint of agricultural sector by being integrated with renewable systems, contributing decarbonization energy. Although solar technologies tend be more accessible cover system’s energy demands, are subject installation area restrictions, limiting potential. This research evaluates advantage...

Utilization of wasted heat instead of fuel combustion is effective to reduce primary energy consumption for mitigating global warming problem. Because wasted heat sources are not necessarily located close to areas of heat demand, one of the difficulties is that wasted heat has to be transferred from heat source side to heat demand side, which may require heat transportation over long distance. ...

A rigorous mathematical approach is developed for optimization of sustainable single-effect water/Lithium Bromide (LiBr) absorption cooling cycles. The multi-objective formulation accounts for minimization of the chiller area as well as the environmental impact associated with the operation of the absorption cycle. The environmental impact is quantified based on the global warming potential and...

With attention to the thin film structure of colloidal quantum dot solar cells, in this paper in order to improvement of active layer absorption of them, we have proposed the use of nanostructure pattern for enhancement of their performance. For this purpose we have presented suitable nano hemisphare patterns in colloidal quantum dot solar cells for light trapping in absorption layer. Then with...

The environmental performance of a combined cooling, heating, and power system is analyzed in this study at component-level using SPECO-based exergoenvironmental analysis. engine consumes natural gas produces 168.6 kW net power. waste heat recovered by LiBr-H2O absorption chiller exchanger, which are used for cooling heating purposes. energy assisted solar field. An Life Cycle Assessment quanti...
