“…For the module of the dual-function solar collector integrated with building in space heating mode, it is necessary to analyze the heat transfer of the four main components: the glass cover, the absorber, the air heating in the air duct, and the insulation backboard. Note that the insulation backboard is treated as one added material layer of the neighbouring facade, and the calculation of insulation backboard relates to the calculation of the building facade in [14].…”

A newly designed solar collector named dual-function solar collector is proposed. The dual-function solar collector integrated with building can perform in two different modes: working as a passive space heating collector in cold sunny days such as in winter, or working as a facade water heating collector in hot days such as in summer. An experimental study has been carried out to investigate the performance of the novel system in space heating mode, whilst, the dynamic numerical model has been established and validated. The experimental and numerical results show that during the period of the measurement from 9 : 00 to 17 : 00, the mean indoor temperature was up to 24.7°C while the mean ambient temperature was only 4.8°C, and a temperature stratification was present in the room. Moreover, a numerical study on the effect of optical property of coatings has been carried out.dual-function solar collector integrated with building, passive space heating, water heating, building energy efficiency, selective absorbing coating, nickel-alumina coating, black paint Citation:Ji J, Luo C L, Sun W, et al.

“…To study the performance of a novel Trombe wall with photovoltaic cells Jie et al [9]developed an unsteady numerical model, performed computations and reported results for the variation of temperature of the system over a week of time using real meteorological data. Jie et al [10] used a similar model to study the effect of selective thermo-insulation facades on the performance of a Trombe wall system and reported results of calculations for 24 hours. A similar model was developed by Shen et al [11] to compare the thermal performances of the classical Trombe wall and a composite Trombe wall in cloudy and cold climates.…”

In this work, a numerical method is developed for solving the unsteady Navier-Stokes and energy equations in a two-dimensional passive heating Trombe wall system. A parallel computer code that can be run efficiently on multicore PCs or networked workstations is developed for calculating the velocity and temperature fields in the whole domain of the system. The developed code is validated using data from the literature. Results are presented for the time response of a typical classical Trombe wall system to transient heating.

Passive solar heating systems are very attractive because of their exploitation of solar energy which is available and abundant. A passive solar system contributes with storage and direct gain to heat a building without the use of mechanical equipment. This investigation is a verification of the Trombe wall efficiency in Tunisia via an experimental study on a real building with a specificity of the local weather. The experimental study was carried on a south wall under real scale in the laboratory of thermal processes in the Center of Research and Technology of Energy (CRTEn) in Borj Cedria. During two different winter periods (January and April), the thermal performance of the wall was investigated using the collected data of velocity and temperature at different positions of the wall. The heat gain through the wall was calculated and the efficiency was found to decrease from January period (45%) to April period (31.7%). The results show that the Trombe wall ensures free heat in winter and can greatly increase the energy efficiency of a building. Thus, the Trombe wall integration to the building design offers many opportunities to take advantage of the Tunisian moderate climate.
