WIPO Patent Application WO/2021/256645
Kind Code:
A1
Abstract:
The present invention provides an air circulator for efficiently removing harmful substances, such as fine dust having small particles, and bacteria and viruses which are attached to fine dust, at low costs and with low energy, the air circulator comprising an air circulator having the function to remove harmful substances such as fine dust, wherein a precision filter and an external air fan are provided in an indoor discharge zone to sequentially remove fine dust from the side of a total heat exchange module, and an internal air fan is provided in an outdoor discharge zone. A total heat exchange element comprises: a heat exchange plate separated into an anode heat exchange plate and a cathode heat exchange plate which face each other; and a spacer inserted between the anode heat exchange plate and the cathode heat exchange plate to form a space, wherein, during normal operation, external air flows into an outdoor suction zone through an outdoor inlet, passes through the total heat exchange element and the precision filter of the indoor discharge zone, and is then discharged indoor through an indoor outlet, and, during a back wash operation, air is moved through a path from the precision filter to the outdoor suction zone.
