Recently builders have shown considerable interest in combining the features of active and passive solar space heating systems into a hybrid system employing active collection and some form of passive discharge/storage device. Ye examined the performance and economics of a hybrid2 air-based, residential system using 18.5 m of roof-mounted air collectors and a hollow-core slab that discharges di...

WC introduce a new technique for rapidly heating (10’ “C/s) thin films using an electrical thermal annealing (ETA) pulse technique. By applying a high-current dc electrical pulse to a conductive substrate-heater material (Si), joule heating occurs thus heating the thin film. This method was demonstrated by heating thin films of aluminum at rates ranging from lo3 to lo6 “C/s. The temperature of ...

− Seat occupancy detection systems based on a capacitive or an electric field principle, developed for an automobile seat, may not work well for seats with integrated electric heating systems. A new detection method, suitable for this type of automobile seats, is presented in this paper. In the proposed scheme, the heating element is a part of the sensor system while its operation as a heating ...

The aim of the work is to chose the best heating system for a museum building. The paper presents the criteria describing this problem. The three technically acceptable heating systems have been identified. The method allowing for the multi-criterion analysis has been selected with the assumption that the final result will be a final ranking of all alternatives. The ELECTRE III method has been ...

As the living standards of Chinese people have been improving, the energy demand for cooling and heating, mainly in the form of electricity, has also expanded. Since an integrated cooling, heating and power supply system (CCHP) will serve this demand better, the government is now attaching more importance to the application of CCHP energy systems. Based on the characteristics of the combined co...

This paper studies power management in a grid-tied hybrid energy system consisting of photovoltaic array, wind turbine, fuel cell, electrolyzer, hydrogen storage tank and a combinational heating system to supply the thermal and electrical demand of a building. Moreover, the hybrid system is capable of exchanging power with local grid. Thus, variable daily buying and selling tariffs are also tak...

In this work, the investigation of wave absorption, phase formation, crystal structure and magnetic properties of SrFe12O19 hexa-ferrites nanoparticles that synthesized by co-precipitation using a microwave heating system and polyaniline-SrFe12O19 was carried out by using a combination of vector network analyser (VNA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier tra...

This study investigated thermal ablation and skull-induced heating with a 230 kHz transcranial MRI-guided focused ultrasound (TcMRgFUS) system in nonhuman primates. We evaluated real-time acoustic feedback and aimed to understand whether cavitation contributed to the heating and the lesion formation. In four macaques, we sonicated thalamic targets at acoustic powers of 34-560 W (896-7590 J). Ti...

In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...
