Under the background of global advocacy of green, low-carbon and sustainable development, all walks of life are actively exploring new technologies and methods for energy conservation and emission reduction. As one of the important pillars of the global economy, the shipping industry's impact on the environment has been paid more and more attention. In recent years, with the progress of science and technology and the improvement of environmental awareness, an innovative scheme of applying air purification technology to the interior of ships and realizing energy saving by optimizing the design of door handles-"air treatment machine with ship door handles" came into being.

I. Background introduction

Traditional ships not only consume a lot of fuel to produce greenhouse gas emissions, but also the air quality in the cabin is often affected. Especially in a closed space for a long time, harmful substances are easy to accumulate and affect the health of passengers. At the same time, frequent door opening and closing will also lead to the increase of cold and hot air exchange, which makes the air conditioning system need to work more frequently to maintain a comfortable temperature, thus increasing energy consumption.

Second, the technical principle

1. Air purification: The "air treatment machine" adopts advanced filtration technology and ion generator to effectively remove suspended particulate matter (PM2.5), bacterial viruses and volatile organic compounds (VOCs) in the cabin air, thus ensuring the indoor air quality.

2. Intelligent induction door handle: The new door handle has a built-in microprocessor and sensor, which automatically opens when someone approaches, thus avoiding unnecessary door opening times caused by human touch; In addition, it will automatically enter the low power consumption mode when it is not used, reducing power waste.

3. Linkage control: The system can also be linked with other equipment on board, such as air conditioning and lighting, so as to adjust the operation state according to the actual demand and further reduce the overall energy consumption.

Third, the implementation effect

　　ince the introduction of this technology, many internationally renowned cruise ships and freighters have successfully applied it and achieved remarkable results:

-Significantly improved the air quality in the cabin, providing passengers with a safer and more comfortable travel experience;

　　-The energy loss caused by frequent door opening and closing is reduced, and according to preliminary statistics, the energy consumption of air conditioners can be saved by about 10% to 15%;

-For long-term offshore operators, a good working and living environment is conducive to improving work efficiency and quality of life.

Fourth, the future outlook

Although this technology is still in the popularization stage, its potential value has been widely recognized. It is expected that in the next few years, the popularity of "air treatment machine with ship door handle" will continue to rise, becoming one of the key forces to promote the transformation of marine transportation industry to green environmental protection. At the same time, relevant research institutions are constantly exploring how to further improve this technology to better serve the development goals of human society.
