Along with the requirement of people on the indoor air quality is higher and higher, the simple air conditioning system can not meet the requirement of people on fresh air, so the fresh air system is more and more favored by people, and is particularly more obvious in northern areas with poorer air quality.
The utilization ratio of new trend system is the highest in the transition season, but traditional new trend system can only carry out simple purification treatment to outdoor air, and when the indoor outer difference in temperature was great, the new trend of following outdoor input can lead to the fact the influence to indoor temperature. For example: in winter, the outdoor low-temperature air is purified by the fresh air system and then is input into the room, the indoor temperature can not reach the target temperature set by the user all the time, and the air conditioner continuously heats.
