The paper mainly deals with the match of solar refrigeration, i.e., solar/natural gas-driven absorption chiller (SNGDAC), solar vapor compression–absorption integrated refrigeration system with parallel configuration (SVCAIRSPC), and solar absorption-subcooled compression hybrid cooling system (SASCHCS), and building cooling based on the exergoeconomics. Three types of building cooling are cons...

the use of solar collectors in combination with heat pipes is rapidly growing in recent years.heat pipes, as heat transfer components, have undeniable advantages in comparison with other alternatives. the most important advantage is their high rate of heat transfer at minor temperature differences. although there have been numerous studies on the heat analysis or first thermodynamic analysis of...

AirConditioning Engineers (ASHRAE RP-1462). It is a three years' research, including the literature review, labs construction, experiments and data analysis. In this thesis, first of all, we conducted literature review of mechanism motion influence on heat and mass transfer and additive effect in absorption chiller. This part helps us understand the basic idea of how mechanism motion affects th...

Compared to a photovoltaic array, photovoltaic/thermal concentrator module can produce thermal power for various productions in downstream cycles addition electrical energy. In this study, the system combined production of electricity, heat and cooling based on has been evaluated. triple system, lithium bromide-water absorption chiller with capacity 5 kW was used. organic Rankine generation cyc...

This work defines and analyzes the performance of a polygeneration system in five different locations Spain to maintain thermal comfort air quality an office building. The facility is based on chiller CHP engine with PV panels that provide almost all electricity demand chiller. According energy analysis results, installation working Bilbao full since no needs be imported from grid summer. To qu...

The aim of this study is to analyze the feasibility single-effect H2O/LiBr absorption heat pump cycle produce combined heating and cooling. To achieve this, first, main changes that requires are described in comparison with conventional chiller. Then, cycle’s operational limits terms temperature lift LiBr crystallization evaluated. In sense, driving temperatures required for these applications ...

Cogeneration and trigeneration systems have been broadly employed as part of the strategies oriented toward rational energy use. The assessment these must include simultaneous considerations costs, irreversibility, losses, their causes. This work presents a step-by-step thermoeconomic analysis microcogeneration unit, composed an internal combustion engine ammonia-water single-effect absorption ...
