An experimental and mathematical study of efforts of a novel photovoltaic-Trombe wall on a test room

Abstract

SUMMARYA novel photovoltaic-Trombe wall (PV-TW) is proposed and investigated experimentally and theoretically in this paper. The PV-TW was installed at the south-facing external wall of an environmental chamber that carried two identical test rooms. Both of the test rooms have a double window of the same size. One test room was installed with the PV-TW (known as the PV-TW room), and the other without PV-TW (known as the reference room). The influence of the PV-TW on the thermal environment of the test room was investigated under different operating conditions. The experimental results show the dual benefits of the PV-TW system: improving the room thermal condition and at the same time generating electricity. Compared with the reference room, the maximum indoor temperature was found to be 5278C higher in winter, and the daily electrical output reached about 0.3 kWh with a PV cell area of 0:72 m 2 : Also, a detailed model is given to evaluate the performance of PV-TW theoretically, and the PV-TW room is simulated under one certain operating condition. The simulated and measured air temperatures of PV-TW room are found to be in good agreement.

A review of designs and performance of façade-based building integrated photovoltaic-thermal (BIPVT) systems

“…They found that the mean indoor air temperature in the room with PV-G Trombe wall was higher than that in the reference room without PV-G wall with ranges from 5-7 °C. Ji et al [39][40] [41][42] studied the effects of thermal insulation and shading curtain on the performance of PV-G systems in Hefei, China through simulations. They found that with the application of thermal insulation to PV-G, the electrical efficiency was decreased by 2% while the indoor air temperature was increased by 2.4 °C in winter and decreased by 2.5 °C in summer.…”

A state of the art review of PV‐Trombe wall system: Design and applications

“…The energy efficiency of BIP−/TE system was 1.26 higher than a massive wall. An environmental chamber with a roof‐top was integrated with PV‐TW to investigate the overall system performance in Hefei, China . Generating electricity and improving the room thermal condition were confirmed experimentally and theoretically.…”
