Problems solved by technology

However, the air change mode of the existing fresh air system adopts the indoor and outdoor continuous cycle air change mode of 30 seconds of air intake and 30 seconds of air outlet (scheduled air intake and regular air output), which has the following disadvantages: the continuous intake of outdoor fresh air speeds up the consumption of purification system consumables ; When the wind is out, the air entering the room due to the negative pressure is the dirty air outside, which greatly wastes the purification effect and the efficiency is low

Abstract

The invention relates to an indoor air purification device, in particular to a central ventilation system control method and control assembly for increasing ventilation efficiency and improving ventilation effect. The central ventilation system control method comprises the steps that a detector detects suitability degree of indoor air; a time detector detects continuous ventilation time of a central ventilation system; a controller controls work states of the central ventilation system; a driving mechanism switches the work states of the central ventilation system, wherein when the detector detects that the suitability degree of indoor air is lower than the standard, the controller transmits a switch driving signal to the driving mechanism; when the time detector detects that the working time of the central ventilation system lasts to the set time, the controller transmits a reverse driving signal to the driving mechanism; the above processes are repeated until the detector detects that the suitability degree of indoor air reaches up to the normal standard, and the controller transmits a homing driving signal to the driving mechanism; the above processes are repeated. The central ventilation system control method and control assembly can increase ventilation efficiency and improve ventilation effect of the central ventilation system.

Description

Technical field [0001] The invention relates to an indoor air purification device, in particular to a fresh air system control method and a control component for improving air exchange efficiency and air exchange effect. Background technique [0002] With the development of the national economy and the improvement of people's living standards, people have higher and higher requirements for the comfort of their living environment, especially the freshness of indoor air, which has received more and more attention. The fresh air system is an electrical product to deal with indoor air pollution. Divided into central system and household and commercial stand-alone system. The central system is often installed together with the central air conditioning, which is necessary for large shopping malls and supermarkets. Independent stand-alone system, small size, easy installation, suitable for household use. Air pollution is an unavoidable problem. The fresh air system can process the fr...
