Operation energy saving of central air conditioning based on auto-counting of people number

ABSTRACT

In the background of low carbon emission reduction, today's society has put forward higher requirements for improving the energy use efficiency of buildings and reducing building energy consumption, and reducing the energy consumption of central air conditioning systems in public buildings is also very important. Due to the persistence of the COVID-19 in recent years, the equipment with functions of temperature detection and reporting has become an essential way to prevent COVID-19 transmitting in public places. In this paper, a body temperature detection and data collection system is designed and further optimized, the number of people collected by this system is used as a basis to regulate the cooling load of central air conditioning to achieve energy saving. © 2021 IEEE.
