Simultaneous heat and water recovery from flue gas by membrane condensation: Experimental investigation, Applied Thermal Engineering (2016), doi: http://dx.doi.org/10.1016/j.applthermaleng. 2016.11.101 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. 1Simultaneous heat and water recovery from flue gas by membrane A tubular ceramic membrane is investigated as the condenser for simultaneous heat and water 2 recovery from flue gas. The effects of the operational parameters, such as fluid (gas and water) 3 flow rates, temperatures of flue gas and coolant water, and flue gas humidity on the process 4 performance in terms of mass and heat transfer across the membrane are studied. Particularly, 5 the overall heat transfer coefficient is also evaluated. As the gas flow rate increases, water and 6 heat transfer efficiencies and recoveries decline due to the reduced residence time. Increasing 7 the water flow rate or lowing the coolant temperature can effectively improve mass and heat 8 transfer efficiencies and recoveries. Increasing the temperature of the inlet gas can enhance 9 water and heat fluxes and recoveries, but does not improve the overall heat transfer efficiency. 10The rise in flue gas humidity can dramatically improve water and heat transfer rates and the 11 overall heat transfer coefficient, but has little effect on water and heat recoveries. These 12 results offer a general guideline in optimising the operational parameters in low-grade heat 13 recovery with membrane heat exchangers, and it may greatly advance the development of 14 membrane condensation technology for practical low-grade heat recovery.

This chapter introduces a comprehensive overview about the principles, challenges and applications of adsorption refrigeration systems (ARSs), as a promising sustainable solution for many of cooling and heating applications. In addition to the features and the basics of ARSs, the following topics have been covered such as characteristics of working pairs, trends in improving the heat and mass transfer of the adsorber; advanced adsorption cycles and performance and operational data of some adsorption refrigeration applications. In some details, the operating range and the performance of ARSs are greatly affected by the employed working adsorbent/refrigerant pairs. Therefore, the study, development and optimum selection of adsorbent/refrigerant pairs, particularly the composite adsorbents, can lead to improving the performance and reliability of ARSs. Regarding the enhancement of heat and mass transfer in the adsorbent bed, two methods are commonly used: one is the development of adsorbents through different coating technologies or new materials such as metal-organic frameworks, and the second is the optimization of the adsorber geometrical parameters and cycle modes. Finally, a brief on some adsorption chillers applications have started to find their share in markets and driven by solar or waste heats.

Summary A novel power/cooling system integrated with organic Rankine cycle and absorption‐compression refrigeration cycle was proposed in order to realize the cascade utilization of low‐grade energy. In the proposed system, R1234ze(E) (trans‐1,3,3,3‐tetrafluoropropene) is used as the working fluid for the organic Rankine cycle subsystem and the binary mixtures of R1234ze(E) with three ionic liquids [HMIM][BF4], [EMIM][BF4] and [OMIM][BF4] are used as working fluid for absorption‐compression refrigeration cycle subsystem due to their superior environmental protection property and physicochemical property. Moreover, in order to recover the heat of the exhaust gas from turbine in organic Rankine cycle subsystem, the exhaust gas is mixed with R1234ze(E)/ionic liquid solution directly in desorber, while the heat of refrigerant from desorber is recovered to reduce the heat load of condenser. The proposed system has much higher energy and exergy efficiency and lower heat load of condenser than reference system. Under specific conditions, increases of 0.24 and 0.07 in thermal efficiency and exergy efficiency of reference system can be achieved. The effect of distribution ratio, expansion ratio, heat source temperature, condensation temperature, generation temperature, evaporation temperature and compression ratio were analyzed for better design in actual application.
