To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air co...

The current study aimed at delving into the thermodynamic of a trigeneration cycle based on biomass fuel, combined with an Organic Rankine Cycle (ORC) and absorption chiller. Biomass fuel is purely produced from Municipal Solid Waste (MSW). Energy exergy analyses were carried out using solar collector employing optimized characteristics to provide required thermal energy ideal condition utilizi...

This thesis investigates the problem of regulating the temperature of a conditioned space using a Solar Assisted Air Conditioning Systems (SAACS) prototype located at Cabo Rojo, Puerto Rico. The SAACS Prototype consists of a 66 flat plate solar collector array with 115.4 m 2 of selective surface area, a 35 kW single-effect lithium-bromide absorption chiller, a 84 kW cooling tower, a 50 kW auxil...

The Broad Two Stage, Steam Driven Absorption Chiller

Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...

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...

In this paper, a detailed simulation model of a solarpowered triple-effect LiBr–H2O absorption chiller is developed to supply both cooling and heating demand of a large-scale building, aiming to reduce the fossil fuel consumption and greenhouse gas emissions in building sector. TRNSYS 17 is used to simulate the performance of the system over a typical year. A combined energeticeconomic-environm...

This study presents a thermodynamic model for determining the entrainment ratio and double choke limiting pressure of supersonic ejectors within the context of heat driven refrigeration cycles, with and without droplet injection, at the constant area section of the device. Input data include the inlet operating conditions and key geometry parameters (primary throat, mixing section and diffuser ...
