Abstract
Energy efficiency is a fundamental factor on ensuring sustainable use of resources and minimizing environmental impacts. In this context, heating systems represent a significant portion of energy consumption in buildings. Wall-mounted radiators are used for indoor heaters due to their ease of installation and maintenance. Therefore, conducting tests on prototypes of wall-mounted radiators is important to evaluate their performance. This study aims to evaluate the thermal and energy performance of a wall-mounted thermosyphon radiator under different operating conditions and its filling ratio (from 30 to 60%). Experimental tests were carried out on a test rig with a controlled environment, containing two wall-mounted radiators, one using the conventional working principals and the other using the principle of the thermosyphons. The prototypes were both made of stainless steel with the same geometry, having an internal volume of 4.45L. The conventional wall-mounted radiator used oil as the working fluid while the wall-mounted thermosyphon radiator used distilled water. The system to evaluate the temperature used thermocouples (type K for the probe and for the surface) to measure the internal and surface temperatures of each prototype, respectively. In addition, for the energy analysis, a system was implemented to measure the values of current, voltage, and power consumed by each apparatus, as well as the measurement of environmental parameters, such as ambient temperature and relative humidity of the air. Data were also collected on the time required for the total heating of both equipments to reach the steady-state. The results will be statistically analyzed to evaluate the effects of the phase change process on the performance of the conventional prototype, which may indicate that the application the thermosyphon concept in wall-mounted radiators can be a promising and sustainable strategy to improve the thermal performance of these devices. Furthermore, the study of this technology can contribute to the development of more efficient and sustainable equipments. Also, it is an effective strategy to improve the performance and to reduce the energy consumption of these devices.
