There is no ventilator installed in the hotel lobby.

It doesn't matter whether the hotel lobby is installed or not. The hotel room should be installed a little, otherwise it will smell very heavy.

The hotel environment is generally closed, and there are many people in the room when dining. Poor ventilation, the smell of wine and smoke in the room can not be handled, and the comfort is poor. The installation of fresh air system can directly discharge the indoor odor and turbid air to the outside, and the indoor air quality is better.

Ventilation fan is a kind of air-conditioning electrical appliance, which is driven by motor to rotate blades and drive airflow, so that indoor and outdoor air can be exchanged. Also called ventilator. The purpose of ventilation is to remove indoor dirty air and adjust temperature, humidity and sensory effect.
