Evaluation of backscattered intensity to quantify the destruction rate of echogenic liposomes

This work focused on a compound PV/T waste heat driven ejector-heat pump system for simultaneous data centre cooling and waste heat recovery for district heating. The system uses PV/T waste heat as the generator’s heat source, acting with the vapour generated in an evaporative condenser as the ejector drive force. Conventional and advanced exergy and advanced exergoeconomic analyses are used to determine the cause and avoidable degree of the components’ exergy destruction rate and cost rates. Regarding the conventional exergy analysis for the whole system, the compressor represents the largest exergy destruction source of 26%. On the other hand, the generator shows the lowest sources (2%). The advanced exergy analysis indicates that 59.4% of the whole system thermodynamical inefficiencies can be avoided by further design optimisation. The compressor has the highest contribution to the destruction in the avoidable exergy destruction rate (21%), followed by the ejector (18%) and condenser (8%). Moreover, the advanced exergoeconomic results prove that 51% of the system costs are unavoidable. In system components cost comparison, the highest cost comes from the condenser, 30%. In the same context, the ejector has the lowest exergoeconomic factor, and it should be getting more attention to reduce the irreversibility by design improving. On the contrary, the evaporator has the highest exergoeconomic factor (94%).

Power Generation Cycle

Most of the potable water and electricity are produced by dual purpose plants. Dual-purpose plants are the one that supplies heat for a thermal desalination unit and produces electricity for distribution to the electrical grid. In this paper a power plant is combined with a multi-effect evaporation thermal vapor compression (METVC) system. Compared with the most widely used (Multi Stage Flash) MSF desalination, METVC has more advantages. Then, energy and exergy analysis equations for desalination plant, power generation cycle, heat recovery steam generator and combined power and water cycle are developed and the results are presented. Results show by rising number of effect from 2 to 14, performance ratio, exergy efficiency and specific heat transfer area rise steadily. For combined system, the maximum and minimum values of exergy destruction rate are related to combustion chamber and desalination effects, respectively. Also, with increasing TIT, exergy destruction rate of power generation cycle decreases while the exergy destruction rate of METVC, especially thermo compressor, goes up and fresh water production reduces dramatically.
