A project to power a domestic oven by solar energy was developed. The focal axis of a cylindrical parabolic reflector usually reaches temperatures of up to 250ºC. A heat transfer fluid carries this heat to the heat exchanger in the oven. Current domestic ovens are generally electric and can reach 250ºC with a power of 2-3 kW.
The installation is composed of pumps, valves, thermally insulated pipes, exchanger, etc. These elements transfer the heat collected by the solar collector to the oven in the house. If the installation has an accumulator tank with thermal insulation, the high temperature liquid makes it possible to use the oven at any time.
Unlike current domestic solar ovens, this technology can reach the same temperature and power as an electric oven, and be used indoors at any time.
Additionally, this system could be used for sanitary hot water purposes and radiating floors. In these cases, the high temperature is degraded mixing with cold water.Postprint (published version
