Hydronic heated pavement system performance using a solar water heating system with heat pipe evacuated tube solar collectors

A Coupled Modelling Method for the Evaluation of the Impact of Pavement Solar Collector on Urban Air Temperature and Thermal Collection

“…It is necessary to combine the canyon, pavement and PSC system to simulate the temperature reductions and thermal collection at the same time. This has not been explored in previous research (Daniels et al, 2019, Bobes-Jesus et al, 2013, Nasir et al, 2017a and the limitation of existing models. Little research discussed the influence of the urban environment on the thermal performance of pavement solar collectors.…”

“…Based on the review, previous studies focused on various methods for minimising the UHI phenomena. Numerous studies (Daniels et al, 2019, Bobes-Jesus et al, 2013 focused on the influential factors and parameters for improving the asphalt solar collectors heat collection efficiency. The work (Nasir et al, 2017a) investigated the influence of pipe layout, embedded pipe depth, pipe spacing, pipe diameter, the flow rate of the medium used for the heat transfer, thermal conductivity, etc.…”

“…The study by Papadimitriou et al (2019) highlighted PSC's potential to provide the urban environment's thermal energy requirements. The thermal energy collected by the PSC system can be stored and then used for covering buildings' thermal loads, and other city facility needs (Chen et al, 2009, Wang et al, 2011, such as water heating for neighbouring buildings and snow melting (Daniels et al, 2019).…”

“…The study by Chen et al (2009) showed that the PSC system could reduce the surface temperature by up to 5°C, reducing the UHI effect and potentially extending the lifecycle of pavements up to 5 years. During the winter, the work (Daniels et al, 2019) proposed that the heated pavement systems can be used for snow melting and de-icing. The experiment showed that during winter daytime, when the sky is clear, the system could raise the storage temperature to 11.5°C and the pavement could maintain a snowfree surface under the condition of subfreezing with six hours snowfall.…”

Evaluation of Anti-icing Emulsified Asphalt Binders

“…However, these traditional methods not only demand a lot of professional workers and equipment but also may lead to high pollution and cause serious damages to the performances of pavements (Henry, 1991;Yehia and Tuan, 1999). To solve these problems of above passive ice-removal method, the anti-icing methods based on thermal melting technology have been studied and proposed, such as heating wire, infrared heating, microwave heating, solar energy collection technology, and electrically conductive pavements; these technologies are proved to be highly efficient in road deicing (Liu et al, 2007;Tang et al, 2008;Wang et al, 2008;Chen et al, 2011;Zhou et al, 2011;Pan et al, 2015;Daniels et al, 2019). Nevertheless, the pavements with heating systems are much more expensive and difficult to build than the normal pavements currently.…”
