VENTILATION SYSTEM

摘要

The climate control system comprises a ventilator (1) controlled by control means (9), and a switch (30) connected to the ventilator system (31) in such a way that the ventilator system may work at either a high speed or a low speed. The ventilator will run at a low speed if the room to be ventilated is occupied, and at a high speed if the room to be ventilated is unoccupied.
