| dcterms.abstract | There is sustained concern on the significant proportion of hot water expenditure to domestic energy consumption. Showering, which statistically takes a major role in household hot water usage, should be taken into consideration. Energy wasted in hot water showering is always examined to minimize by introducing hot drain recovery system into residential segments but to root out the wastage, the source, heat generated in showering water, should be explored. Thus, this study aims to reveal the parameters in showering by investigating heat energy conversion process through the amount of water jets with its relationship to human response. Efficiency in heat exchange between human skin and hot water during showering is examined by a model. Laboratory experiments will be conducted to study the energy transaction and a survey will also be carried on to illuminate the thermoregulation. The number of water jets from shower head as one of human flavour of showering will be taken in for advanced interest. This supposes to verify any human thermo-psychological phenomenon that the more water jets spray on skin, the higher efficiency in heat exchange occurs, the more comfortable human feels. The experimental results, by coincidence, revealed that efficiency in heat transfer by convection does not obviously link to number of water jets. Other factors of hot water showering rather than heat exchange efficiency are concerned more. It is hoped that this study can further develop to determine the relation in evidence and grip general attention at daily behavioural and household hot water energy consumption. | en_US |
