Intelligent wind system and control method thereof

Abstract

The invention relates to an intelligently controlled ventilation system capable of improving indoor air quality. Under control of a computer main control machine, the system comprises at least one frequency conversion driving full-heat exchange bidirectional ventilation fan, an air quantity control switch which corresponds to each ventilation sub-area and controls the opening, closing and air quantity of each ventilation sub-area, and a digital control adjustment air door, wherein at least two independent ventilation sub-areas are built; and the frequency conversion driving full-heat exchange bidirectional ventilation fan conducts outdoor fresh air into each ventilation sub-area indoors and exhausts the turbid air in each ventilation sub-area indoors. In the system, a way of manual control and / or intelligent control can be adopted. The system intelligently controls different ventilation sub-areas, ventilates different ventilation sub-areas according to actual needs, realizes fixed point, quantificational and fixed timing control, and fully saves energy; and rich negative oxygen ions are added into the fresh air conducted indoors.

Description

technical field

[0001] The invention belongs to industrial control and heating and ventilation engineering technology, in particular to an intelligently controlled ventilation system capable of improving indoor air quality. Background technique

[0002] In the era when the concept of health and environmental protection has entered the homes of ordinary people, improving indoor air quality has increasingly become a common requirement of people. Some ventilation systems in the past generally include ventilation and air purification functions. For example, CN1727785 discloses a ventilation system integrated with an air purification device, which includes: an air supply pipe, an exhaust pipe, an air supply fan, an exhaust fan, a total heat exchanger, a common ventilation passage, a circulation passage, and an air purification device. Another example is that CN1727783 discloses a kind of indoor air quality control device and method utilizing a ventilation system, and its control...
