a review on loop heat pipe for use in solar Water Heating
Energy and Buildings, 2014Co-Authors: Zhangyuan Wang, Wansheng YangAbstract:Abstract In this paper, a comprehensive review on the loop heat pipe (LHP) for use in solar Water Heating (SWH) will be carried out. LHP is an efficient heat transfer device that could transport thermal energy over long distances, up to several tens of meters. It has some unique features over conventional heat pipe, e.g., gravity-unaffected and flexibility in its design and installation, which makes LHP particularly suitable for applications in SWHs. A significant literature review of the LHP technology will be illustrated, and the review results will be analyzed in terms of the performance characteristics and research methodology. For the performance characteristics, the steady-state and transient behavior of the LHP device will be examined. The research methods, i.e., theoretical analyses and computer simulations, and experimental investigations, will be analyzed. Although substantial work has been done in LHP studies, the opportunities for further work will be identified. This review will help recognize the problems remaining in the existing SWHs, remove the barriers to solar applications, identify new research subjects to improve the performance of the SWHs, expand solar thermal market potential throughout the world and broaden the application of LHP in solar Water Heating.

review of the phase change material pcm usage for solar domestic Water Heating systems sdwhs
International Journal of Energy Research, 2018Co-Authors: Mohamed Hany Abokersh, Omnia Elbaz, Mohamed Elmorsi, Mohamed Osman, Osama SharafAbstract:Summary The shortage in energy resources combined with the climb in greenhouse emissions is the main incentive beyond the deployment of solar energy resource in various applications. One of the most successful applications is the utilization of solar energy in the domestic Water Heating systems (DWHS) because 70% of the consumed energy in the residential segment is utilized for space Heating and appliances in cold climates [1]. However, the full deployment of solar energy in domestic Water Heating is only possible when an energy storage system with acceptable price is available. Recently a new tendency for deploying phase change materials (PCMs) as an energy storage system is introduced in several solar DWHS. These systems are known as integrated PCM in solar DWHS and offer several advantages including high storage capacity, low storage volume, and isothermal operation during the charging and discharging phases. The present study reviews various techniques utilized for integrating the PCM in solar Water Heating systems and the utilized methods for enhancing the heat transfer characteristics of the PCM through the usage of extended surfaces and high conductive additives.

performance investigation of thermal energy storage system with phase change material pcm for solar Water Heating application
International Communications in Heat and Mass Transfer, 2014Co-Authors: M H Mahfuz, M R Anisur, M A Kibria, R Saidur, I H S C MetselaarAbstract:Abstract In order to harvest solar energy, thermal energy storage (TES) system with Phase Change Material (PCM) has been receiving greater attention because of its large energy storage capacity and isothermal behavior during charging and discharging processes. In the present experimental study, shell and tube TES system using paraffin wax was used in a Water Heating system to analyze its performance for solar Water Heating application. Energy and exergy including their cost analyses for the TES system were performed. Accordingly, total life cycle cost was calculated for different flow rates of the Heat Transfer Fluid (HTF). With 0.033 kg/min and 0.167 kg/min flow rates of Water as HTF, energy efficiencies experienced were 63.88% and 77.41%, respectively, but in exergy analysis, efficiencies were observed to be about 9.58% and 6.02%, respectively. Besides, the total life cycle cost was predicted to be $ 654.61 for 0.033 kg/min flow rate, which could be reduced to $ 609.22 by increasing the flow rate to 0.167 kg/min. Therefore it can be summarized that total life cycle cost decreases with the increase of flow rate.
