Design of an Energy-saving Home Furnishing Device by Human-body Induction

Abstract

China Certification Centre for Energy Conservation Product found in the investigation that the standby energy consumption accounts for about 10% of the electricity consumption of Chinese family. This paper presents an energy-saving design by human body induction in order to cut off the power supply when no indoor appliances to achieve energy saving. This kind of device can make indoor appliances stop when nobody is in the room. Through the device, it can not only avoid the standby energy consumption of household appliances, but also solve the additional energy issues caused by those who forget to close the electric appliances, thereby reducing the household electricity costs to realize energy saving and emission reduction. Under the background of the national energy-saving and emission reduction policies, home Furnishing energy problem has aroused more and more concern. The additional energy consumption of household appliances mainly includes the standby energy consumption and the operating energy consumption caused by the user who forgets to close the home appliances and keeps those appliances under the unnecessary operating state. All of these cause a large waste a lot of energy inadvertently. The current status of the standby power consumption of household appliances A survey of household standby energy consumption and energy-saving potential by China Certification Center for Energy Conservation Product revealed that the standby energy consumption accounts for about 10% of the electricity consumption of Chinese family. The average standby energy consumption of the city families in our country is equivalent to the situation where these families use an ever-lasting lamp of 15 watts to 30 watts every day. Standby energy consumption is like blood sucking insects sucking electricity and energy everywhere, and meanwhile it also creates enormous pressure on environmental protection. In China, only an item of standby energy consumption of the color TV is equivalent to the total power of several large-scale thermal power plants in the whole country. Reducing the standby energy consumption not only means that consumers can save electricity costs, but more directly reduces the energy waste and environmental pressure. Therefore, reducing standby energy consumption not only is an electric consumption problem, but more becomes a global-concern and far-reaching issue of sustainable development. Before the manufacturer has not provided effective energy-efficient appliances, to close the electric power supply is still an effective way to reduce standby energy consumption. Thus, this design of an energy-saving system by human body induction that can cut off the electrical power when no one in interior can achieve energy saving.
