Along with the improvement of the requirements of people on indoor environment, more and more air conditioning devices are arranged indoors, wherein an air conditioner and a fresh air ventilation system are two devices which are commonly arranged in modern families, and the fresh air ventilation system and the air conditioning system can be controlled in a linkage mode and can also run independently.
During the winter night, the outdoor temperature is usually lower than the indoor temperature, and the outdoor carbon dioxide concentration is also lower than the indoor carbon dioxide concentration. After the user falls asleep at night, the indoor air quality is always continuously reduced, which is very unfavorable for the health of the user, so that the user usually starts the sleep mode of the fresh air ventilation system to automatically ventilate the system so as to improve the sleep environment. However, the existing fresh air ventilation system usually operates in linkage with an air conditioning system in the ventilation process, and the air conditioning system is not required to operate under some conditions, so that the problems of high energy consumption and energy waste are caused. Although some independently-operated fresh air ventilation systems can save energy consumption to a certain extent, the operation mode cannot be adjusted according to the actual indoor and outdoor air quality, and only simple starting, ventilation and shutdown can be realized to stop ventilation, so that the ventilation effect is not ideal, and the requirement of partial users on the comfort level cannot be met.
Accordingly, there is a need in the art for a new method, storage medium, and control device for ventilation during the winter night to solve the above problems.
