Are there any of household air conditioning fresh air?
Some have, some don't However, even with this kind of function, the so-called ventilation or air function, had no obvious effect. Is not significant, but only as a selling point. His principle is what?? Then add a small outdoor bi-directional centrifugal pump, and then through a pipe, the pipe is similar to the low pressure pipe is big, that's less than 1 cm. Then 2 tube and pipe, the pipe and the refrigerant supply all tied together, connect the indoor and outdoor And the tube, no matter how much he flow first Pump work need electricity, although not much, but the pump through a simple filter inhaled air, to indoor, later pumped the indoor air An hour down, ventilation have? In short is fairly small, how much less?? You open a door in volume than the pump work an hour, what does that mean??
Yes, claims to have more qigong can be automatically.Is worse than a few hours to open a window, each window as fast as more than 10 seconds for air, more fully.
Have to do with the brands and models of household air conditioner is in fresh air. (not all)
