Power source voltage-stabilized type automatically-controlled air exchange system

Abstract

The invention discloses a power source voltage-stabilized type automatically-controlled air exchange system. The air exchange system is characterized in that the system is mainly composed of a programmable controller, a voltage-stabilizing rectifier circuit, an A / D converter, a memory, an air exchange control circuit, a power source, an air quality sensor and an air exchange device, wherein the voltage-stabilizing rectifier circuit, the A / D converter, the memory and the air exchange control circuit are all connected with the programmable controller, the power source is connected with the voltage-stabilizing rectifier circuit, the air quality sensor is connected with the A / D converter, and the air exchange device is connected with the air exchange control circuit. The air exchange system is simple in structure and low in cost; the programmable controller judges whether the air exchange device needs to be started or not according to indoor air quality signals collected by the air quality sensor, and therefore the air exchange device can be stopped working when the indoor air quality is good; the purpose that air is automatically exchanged according to the odor generation condition in the environment is achieved, and the air exchange system is suitable for application and popularization.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a power supply stabilized voltage automatic control ventilation system. Background technique [0002] At present, due to the rapid increase of urban population and the needs of urban development, urban buildings are becoming larger and larger. These huge buildings will be divided into multiple independent small spaces, and many of these independent small spaces exist A certain degree of closure cannot ensure smooth circulation with the outside atmosphere, so the odor generated in these spaces is not easy to dissipate automatically. At present, ventilation equipment such as air conditioners or exhaust fans is usually used for ventilation, so as to disperse peculiar smells into the atmosphere and introduce fresh air from the outside. However, most of the ventilation equipment is usually opened as soon as people enter the room, or wait until people smell a peculiar smell through their sense ...

AI Technical Summary

Problems solved by technology

Odor gas is often not conducive to people's health. Waiting to smell the odor before ventilating means that the human body has inhaled the odor gas, and turning on the ventilation equipment will cause great waste. On the one hand, the ventilation equipment needs power consumption, and on the other hand On the one hand, keeping the ventilation equipment open all the time will also cause wear and tear on the equipment
