This paper presents an energy and exergy analysis of a combined power generation system consists of a Proton Exchange Membrane fuel cell (PEMFC) power station and Kalina cycle system 11 (KCS11) that converts low temperature waste heats into electricity. T... see more

Una bomba de calor de expansión directa con energía solar (BCAES-ED) es una tecnología de calentamiento de agua con mucho potencial en países con climas tropicales y húmedos siendo relevante realizar  análisis basados en la energía y la exergía que p... see more

Energy analysis of process has gained popularity overtime and has been used in detecting, quantifying and minimising inefficiencies in processes. This paper illustrates these and goes a step further in showing the relationship between exergy, energy, econ... see more

In this study, energy and exergy analysis is applied for a ceiling type air conditioning (CTAC) system operating with various refrigerants. Firstly, hourly cooling load capacities of a sample building are determined for the months of April, May, June, Jul... see more

In this paper, energy and exergy analysis of typical gas turbines is performed using average hourly temperature and relative humidity for selected Gulf cities located in Saudi Arabia, Kuwait, United Arab Emirates, Oman, Bahrain and Qatar. A typical gas tu... see more

The performance of space heating and cooling systems in buildings is usually measured by applying the first law of thermodynamics, which makes it possible to quantify the energy losses of the single components and to measure their energy conversion effici... see more

Energy management is a technical and management function which is to monitor, record, analyse, critically examine, alter and control energy flows through systems so that energy is utilized with maximum efficiency.  In line with this, a study was cond... see more

The thermal energy storage (TES) system stores the district heating (DH) water when the heating load is low. Since a TES system stores heat at atmospheric pressure, the DH water temperature of 115 °C has to be lowered to less than 100 °C. Therefor... see more

Adiabatic compressed air energy storage (A-CAES) is an effective balancing technique for the integration of renewables and peak-shaving due to the large capacity, high efficiency, and low carbon use. Increasing the inlet air temperature of turbine and red... see more
