| Summary: | A simulation model is proposed for integrated acoustic and thermo-fluid insulation constituting an airflow window with a photovoltaic (PV) solar wall spandrel section. The physical model of an outdoor test-room comprises of a wooden framed double or cavity wall assembly with: (i) a triple glazed fenestration section with a closed roller blind; (ii) a solar wall spandrel section of double-glass PV modules and back panel of polystyrene filled plywood board; and (iii) fan pressure-based manually operated inlet and exhaust dampers with ventilation through an exhaust fan for transportation of heat. A generalized two-dimensional analysis of a double wall structure is illustrated by the placement of surface and air nodes into two adjacent stacks of control volumes representing outer and inner walls. The integrated noise insulation and energy conversion model is presented. The energy conversion and noise insulation model are supported with some numerical results using devised noise measurement equations. The following additional parameters are also calculated to support the integrated insulation model: noise transmission losses and noise reduction coefficients for various types of noises. State-of-the-art of acoustic and thermo-fluid insulation along with general building construction guidelines for acoustic and thermal insulation are also presented. |
