Abstract

The work presented here aims to demonstrate the technical, architectural, and energy viability of solar thermal collectors made with ceramic materials and their suitability for domestic hot water (DHW) and building heating systems in the Mediterranean climate. The proposal is for the design of a ceramic shell, formed by collector and non-collecting panels, which forms part of the building system itself, and is capable of responding to the basic requirements of a building envelope and harnessing solar energy. Ceramics considerably reduce the final cost of the collector system and offer the new system a variety of compositional and chromatic finishes, occupying the entire building surface and achieving a high degree of architectural integration, although less energy-efficient compared to a conventional metallic collector.

Highlights

  • Importance of energy consumption, in relation to environmental issues and the depletion of natural resources, has placed greater emphasis on promoting energy capture through other renewable resources

  • The issues regarding the architectural integration of collector elements are well known; as a result, they are nearly always relegated to rooftops where their presence goes unnoticed

  • The temperature of stagnation (T*|μ = 0 ): is the value of the parameter T* for the when the efficiency of the collector is zero, that is, the collector cannot raise the temperature of the water that is entering for given environmental conditions

Summary

Introduction

Importance of energy consumption, in relation to environmental issues and the depletion of natural resources, has placed greater emphasis on promoting energy capture through other renewable resources. Solar power is perhaps the most prominent of all the renewable energies, according to the European Solar Thermal Industry Federation [1]. That is why the analysis and evaluation of today’s solar thermal collector systems (hereafter STC) is so vital for revealing their limitations and studying improvements and innovations that enable their more widespread usage and the improvement of these aspects
