Working principle of Holtop heat and energy recovery ventilator(HRV & ERV)

Holtop heat & energy recovery ventilator can expel the stale air indoor out of room, meanwhile supplying the fresh air outside into the room, by using the advanced heat/energy recovering technology, the energy can exchange taking advantage of the difference of the temperature and humidity between indoor and outdoor air. By this means, it can not only smooth away the problem of indoor pollution, but also saving energy.
