Simulation Study on Thermal Performance of a Ventilated PV Façade Coupled with PCM

Abstract

This paper presents a dynamic thermal model based on DesignBuilder simulation software platform, for a simple office building model with an integrated ventilated PV façade/solar air collector system in climatic conditions of Bratislava, Slovakia. Thermodynamic simulation has been applied in order to express thermal performance of a ventilated PV façade coupled with phase change material through the whole reference year. Attention is focused on simplified approaches which capture the important elements of the problem. The results of simulation show that natural ventilation of PV façade with added phase change material have ability decrease temperatures of PV panel during extreme days more than 20 °C and shift time of peak temperature even more than 5 hours.

Experimental Study of Thermal Effect of Lacquer Coating for PV-Trombe Wall System Combined with Phase Change Material in Summer

“…Through experiments and transient energy balance approach, Hachem et al [15] and Kibria et al [16] studied the effect of PCM on the performance of PV board and concluded that PCM could decrease the temperature of PV board and increase the electrical efficiency. Curpek and Hraska [17] compared and studied the PV board with and without PCM as well as the flow passage with and without ventilation, the results showed that natural ventilation of PV façade with added PCM could reduce the temperature of PV board better. Aelenei et al [18,19] developed a simplified thermal network model for BIPV-PCM and studied the thermal behavior of the system.…”

A Review on Building Integrated Photovoltaic Façade Customization Potentials

“…Regarding the customization level, four were purely elemental [51,52,80,82], eight were compositional at the module-level [64,81,83,88,89,91,92,95], and five were compositional at the façade-level [17,53,81,84,94]; eight studies combined all of the levels [55,82,[85][86][87]90,93,96]. Comparing elemental versus compositional level, studies can be more easily carried out using conventional PV modules without the requirement of a custom-designed module.…”

“…Statistically, nine of the cases focused on design of a custom BIPV product [51,52,55,[80][81][82][83]89,95], only four focused on a customization in the integration process [63,81,84,94], while 12 combined both product and integration concerns in their research [17,53,63,64,[85][86][87][88][90][91][92][93]. This suggests that most custom BIPV façade products are designed with attention on the potential for proper architectural integration.…”

“…In the investigated cases, three were SPV [64,85,94], four were MCF [51,52,80,89], four were EDM [53,63,81], and 14 combined two or more strategies [17,55,[82][83][84][86][87][88][90][91][92][93]95,96]. Clear evidence thus presents a combination of various strategies is required to achieve BIPV façade customization.…”

“…With regards to the added functions, [17] studies addressed thermal control [17,53,63,[83][84][85][86][87][88][89][91][92][93][94][95], [15] addressed aesthetics [17] and, [11] addressed daylighting functionality based on research objective or cell type selection as all a-Si applications permit some degree of light transmission [7,63,64,82,83,[85][86][87]92,95]. Also, three addressed energy savings [53,83,87], four specifically on shading [85][86][87]92], and one on cladding [90] and cost [93].…”
