Abstract
To mitigate climate change attributed to the built environments, there have been tremendous efforts to improve air conditioning systems in the buildings. The possibility of harvesting body heat as a renewable energy source to power a wearable personal heating system is investigated. The aim of this study is to integrate a wearable personal heating system with a thermoelectric generator (TEG) that harvests the body heat which is used to convert it into electricity. Moreover, the interaction between the TEG configuration and power output is studied. The power generation of TEG system is obtained by COMSOL Multiphysics software. The simulation results concluded that all the four proposed heat sink configurations can improve the power output of the wearable TEG at 1.4 m/s and 3m/s compared to that of the reference model. Furthermore, the perforated and trapezium shapes of heat sinks have a significantly better performance in comparison to conventional heat sinks.
Highlights
Due to global warming and lack of fossil fuel reservoirs, energy conservation measures are gaining more attention than any time before
There is currently few of researches that have been done instead of the battery of these garments, such as a thermoelectric generator (TEG)
This study aims to enhance a wearable TEG power output and investigate four novel configurations to fulfil reliable energy source for personal heating garments
Summary
Due to global warming and lack of fossil fuel reservoirs, energy conservation measures are gaining more attention than any time before. It is noteworthy that space heating attributes to the highest amount of energy consumption in the buildings [2]. HVAC systems are the dominant space heating approach and are designed to provide a uniform thermal condition in the whole building regardless of individuals’ thermal preferences [3]. This becomes more of a challenge when occupants share an office or a workspace, where the thermal preference varies from person to person. Personal heating garment provides the highest thermal satisfaction with the lowest energy consumption [4].
