10 Creative thinking of multi-decision AC control system

Air conditioning (AC) systems with fresh air system have been widely used in some public buildings. When people in a room with AC, some people could feel cold, and the rest of them could feel not cold enough. Misuse and lack of management make public buildings AC in summer high energy consumption and poor indoor air quality (IAQ). Central AC units for some public buildings, including various AC systems renovation, from the end of the intelligent control system with the coordination of the revised host control strategy to achieve the purpose of energy conservation. Through the MCU on the air conditioning control AC end equipment, data judgment and transmission are calculated by the server.

For instance, Wechat as a software plant and a social community software is widely used in China. It can be a commander to send the command to the MCU. People in the room can vote their comfortable temperature to the MCU, then MCU sends the message to the server through Wifi network. After that, server controls the room temperature based on the result of the vote and some IAQ principles and standards, which could lead a little negative influence from the unreasonable vote to the room IAQ.

There is another parameter needing to be considered, which is CO2 concentration. This parameter will have somewhat negative impacts on the office or teaching building. The fresh air system could solve this problem more efficiency with multi-decision AC control system. According to the voting process, the number of people in the room can be counted. Sitting rate can be used as an important parameter for opening the inlet of the fresh air system. This automatic AC control system could contribute comfortable IAQ, simultaneously, it leads to less energy consumption as well.
