Abstract:

Modifications to the quasistatic Carnot cycle are developed in order to formulate improved theoretical bounds on the thermal efficiency of certain refrigeration cycles that produce finite cooling power. The modified refrigeration cycle is based on the idealized endoreversible finite time cycle. Two of the four cycle branches are reversible adiabats, and the other two are the high and low temperature branches along which finite heat fluxes couple the refrigeration cycle with external heat reservoirs. This finite time model has been used to obtain the following results: First, the performance of

Abstract:

This thesis discusses the thermoeconomic modeling and simulation of micro-CHP systems powered by various prime movers. Micro Cooling, Heating, and Power (micro-CHP) is becoming an increasingly important energy option as the demand for electrical power as well as heating and cooling for buildings increases worldwide. Micro-CHP has the potential to increase the total energy efficiency for cooling, heating, and powering residences, offices, and other relatively small buildings by using waste thermal energy from electricity production to deliver heating and cooling. Calculation methodologies are p

I cicli termodinamici dell'anidride carbonica per la produzione di energia sono una nuova tecnologia in fase di ricerca e sviluppo in vari gruppi di ricerca in tutto il mondo. Le principali caratteristiche attrattive dei cicli ad anidride carbonica sono una maggiore efficienza del ciclo, un ingombro ridotto e la loro capacità di integrazione con diverse fonti di calore. Tuttavia, ci sono alcune sfide specifiche dell'applicazione di tali cicli di alimentazione, tra cui una minore efficacia di recupero del calore, un lavoro specifico per il ciclo inferiore e la necessità di schemi di ciclo compl

Abstract:

The interest in utilizing the energy in low‐grade heat sources and waste heat is increasing. There is an abundance of such heat sources, but their utilization today is insufficient, mainly due to the limitations of the conventional power cycles in such applications, such as low efficiency, bulky size or moisture at the expansion outlet (e.g. problems for turbine blades). Carbon dioxide (CO2) has been widely investigated for use as a working fluid in refrigeration cycles, because it has no ozonedepleting potential (ODP) and low global warming potential (GWP). It is also inexpensive, non‐explosi

Abstract:

Globally, there are vast amounts of low-grade heat sources from industrial waste and renewables that can be converted into electricity through advanced thermodynamic power cycles and appropriate working fluids. In this thesis, experimental research was conducted to investigate the performance of a small-scale Organic Rankine Cycle (ORC) system under different operating conditions. The experimental setup consisted of typical ORC system components, such as a turboexpander with a high speed generator, a scroll expander, a finned-tube condenser, an ORC pump, a plate evaporator and a shell and tube

Abstract:

Drying of paper by impinging jets of superheated steam was studied in an apparatus which closely simulates conditions for a potential industrial impingement dryer.<br>Drying was found to consist in a constant rate period, followed by a falling rate period where the drying rate decreases linearly with moisture content. The relation found between the constant rate and Reynolds number and temperature of the jet is consistent with a previous correlation for air impingement heat transfer, suitably modified for conditions in a steam environment. For a given mass flux, steam drying is slower than air

The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems.

Solar power tower technology can achieve higher temperatures than the most common commercial technology using parabolic troughs. In order to take advantage of higher temperatures, new power cycles are needed for generating power at higher efficiencies. Supercritical carbon dioxide (S-CO2) power cycle is one of the alternatives that have been proposed for the future concentrated solar power (CSP) plants due to its high efficiency. On the other hand, carbon dioxide can also be a replacement for current heat transfer fluids (HTFs), i.e. oil, molten salt, and steam. The main disadvantages of the c
