摘要

摘要建立了一个模拟半透明光伏双表面(STPV-DSF)系统的分析模型，以评估其整体性能。STPV-DSF综合建筑可以发电，在其室内区域提供日光照明，并降低建筑的能源需求。在建筑设计阶段，需要进行复杂的仿真来评估STPV-DSF系统的整体性能。本研究的目的是提供一个可靠和直接的计算方法来估计STPV-DSF系统的整体性能。本文对印度夏季和冬季复合气候条件下，STPV-DSF系统在自然通风和强制通风条件下的整体性能进行了评价。在STPV-DSF系统上进行了实验研究，验证了模型的有效性。STPV-DSF系统的实测温度和计算温度与室内太阳热增益吻合较好。对于给定的天气条件，还通过求解能量公式计算了STPV-DSF系统的CO2排放量和环境成本(碳价格和排放的碳量)。结果表明，在夏季和冬季，强制通风条件下STPV-DSF系统的节能性能分别比自然通风高4.08%、9.86%和14.05%，且CO2排放量更少。

Analytical model of semi-transparent photovoltaic double-skin façade system (STPV-DSF) for natural and forced ventilation modes

Abstract An analytical model has been developed for simulating the semi-transparent photovoltaic double-skin façade (STPV-DSF) system to assess its overall performance. The STPV-DSF integrated building can generate electricity, provide daylight illuminance in its indoor area and lowers the energy demand of a building. During the building design phase, complex simulations are required to estimate the overall performance of the STPV-DSF system. The present study's objective is to provide a reliable and straightforward calculation method for estimating the overall performance of the STPV-DSF system. This paper evaluates the overall performance of STPV-DSF system operating under natural ventilation and forced ventilation for summer and winter seasons of Indian’s composite climate. An experimental investigation has also been carried out on STPV-DSF system to validate the model. A good agreement was observed between measured and calculated temperatures of the STPV-DSF system and solar heat gain to indoor area. For given weather conditions, CO2 emissions and environmental cost (carbon price and emitted carbon quantity) have also been calculated for STPV-DSF systems by solving energy formulations. The results depicted that STPV-DSF system under forced ventilation exhibited 4.08%, 9.86% and 14.05% higher energy performance than natural ventilation in summer and winter with less CO2 emissions.
