Exergy recovery during LNG gasification using ambient air as heat source

Exergy Analysis of an Air Dehumidification System Equipped with Mixing Box and Heat Exchanger Heat Recovery Units

Exergy analysis emboldens in cases that all the inefficiencies and bottlenecks to improve energy systems are to be addressed. In this study, a novel vapor compression air dehumidifier integrated with an auxiliary heat exchanger in series arrangement with the main condenser in order to mitigate the reheat coil, and an extra mixing box to recover the ventilated air heat has been introduced. A com...

Exergetic Analysis, Optimization and Comparison of LNG Cold Exergy Recovery Systems for Transportation

LNG (Liquefied Natural Gas) shares in the global energy market is steadily increasing. One possible application of LNG is as a fuel for transportation. Stricter air pollution regulations and emission controls have made the natural gas a promising alternative to liquid petroleum fuels, especially in the case of heavy transport. However, in most LNG-fueled vehicles, the physical exergy of LNG is ...

Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...
