I don't know about other brands, I know the brand of Fennig, they are recommended to install it outside the kitchen, saying that the kitchen is too big and the refrigeration effect on the machine is not good.
The machine that extracts the smoke is a powerful exhaust fan that discharges the smoke from the kitchen.
I think that the brand of Yuanda ceiling fresh fan is better, energy-saving and environmentally friendly, with better performance and more repurchase rate.
Yes, the ceiling-type fresh fan can be installed in addition to the ceiling of the bedroom, mainly concentrated in the bathroom and the kitchen (in most cases, this is the integrated ceiling, which is more convenient to maintain, and the sound of the machine will not affect the user).
Fresh air fan is an effective air purification equipment, can make the indoor air circulating, on the one hand, the indoor dirty air is discharged outdoor, on the other hand, the outdoor fresh air is sterilized, disinfected, filtered and other measures, and then input into the room, so that the room is fresh and clean air all the time, the fresh air fan uses the patented technology of fresh air convection, through independent air supply and air induction, so that the indoor air can achieve convection, so as to maximize the indoor air replacement ======In layman's terms, a kitchen fresh fan is used to keep the kitchen air fresh! It does not change the indoor temperature in the kitchen, whereas the kitchen air conditioner is obviously used to regulate the indoor temperature in the kitchen.
