室内外空气循环系统及其循环方法
摘要：
本发明提出一种室内外空气循环系统及其循环方法，该室内外空气循环系统包括机体，全热交换器，可将所述机体内空气排出至室内侧的第一风机，以及可将室内侧空气排出室外侧的第二风机，所述全热交换器具有两个流道，所述机体上设置有新风口、排风口以及回风口，其中，所述回风口包括自上而下设置的第一回风口和第二回风口；所述第一回风口设置有可关闭或开启所述第一回风口的第一风门，所述全热交换器中第一流道出口设置有可关闭或开启所述全热交换器该空气出口的第二风门；该循环方法为基于上述循环系统。该发明在进行室内空气的内循环时，可完全阻隔室外空气的混入，从而有效的避免了全热交换器结霜的现象，延长了全热交换器的使用寿命。
摘要（英）：

The invention provides an indoor and outdoor air circulation system and a circulation method thereof, the indoor and outdoor air circulation system comprises a body, a total heat exchanger, a first fan discharging the air inside the body to the indoor side, and a second fan discharging the air inside the indoor side to the outdoor side. The total heat exchanger has two flow passages, and the bodyis provided with a fresh air inlet, an air outlet, and a return air inlet, wherein the return air inlet comprises a first return air inlet and a second return air inlet disposed from top to bottom; afirst damper, which closes or opens the first return air inlet, is disposed on the first return air inlet, a second damper, which closes or opens the air outlet of the total heat exchanger, is disposed on the first flow passage within the total heat exchanger; the circulation method is based on the above circulation system. The indoor and outdoor air circulation system and circulation method thereof can completely block the mixing of the outdoor air during the internal circulation of the indoor air, thereby effectively avoiding the frosting phenomenon of the total heat exchanger and prolongingthe lifetime of the total heat exchanger.
