A simplified model to assess the thermal performance of pavement solar collectors

Coupling a road solar thermal collector and borehole thermal energy storage for building heating: First experimental and numerical results

“…These models have been validated using temperature data recorded on pilot RTC plants. Among these approaches we can mention: a new numerical model called HyRoSim that was used to perform the energy assessment of a 70 m 2 pilot RTC built in Östersund, Sweden [29]; a 3D FEM model developed in COMSOL Multiphysics to perform a back analysis of the thermal properties of a 65 m 2 pilot RTC built at Antwerp, Belgium [30] that was subjected to several operational tests [31]; a COMSOL model that was validated with data from a TRT performed on a 42 m 2 pilot RTC built and instrumented in Adelaide, South Australia [32]; and another FEM model developed in COMSOL Multiphysics that was used to perform a back analysis of the thermal conductivity values of the layers of an outdoor asphalt surface in Vaasa, Finland, using temperature data measured at different depths [33]. The model was then also used to simulate the operation of an RTC at the same site.…”

Optimization of Thermal Energy Harvesting Road Pavement using Sustainable Conductive Material in Malaysia by Numerical Simulation

“…The distance between the heating pipes was found to be an important factor affecting the total heat loss and the actual heat exchange between the pipes in the new multi-control heating system [21]. On-site experimental for the thermal performance of pavement solar collectors, the importance of pipe spacing as the model can interact with simulation environments, heat sources, and heat pump for real-time automation [22].…”

Thermal performance of a controllable pavement solar collector prototype with configuration flexibility

“…The momentary (i.e., logged via controller) injected or extracted power 𝑞𝑞 𝑔𝑔𝑔𝑔𝑔𝑔𝑔𝑔/𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 (kW) of the asphalt solar collector system are calculated according to Eq. (1) [13,32]:…”
