Problems solved by technology

At the same time, as the outside air flows in, the load increases and the power consumption of each system increases
[0015] 2. Because the air purifier is set on the ground, it cannot effectively collect dust in the room
Other systems are also located within easy reach of small children, making them prone to misoperation and posing a fall hazard
The above reasons can lead to a shortened service life of each expensive system
[0016] 3. Multiple independent systems will occupy the indoor space separately, making the indoor space narrow
Therefore, it may cause inconvenience to family members or company employees

Embodiment Construction

[0040] Such as figure 2 As shown, the system of the present invention consists of a ventilation system and an air cleaner 10 . The ventilation system performs ventilation by drawing in outside air and exhausting indoor air. The air purifier is linked with the above-mentioned ventilation system to perform corresponding operations, and uses the filtration system to perform air purification operations such as dust collection and deodorization of the indoor air.

[0041] The above-mentioned ventilation system uses the air supply fan to suck in outdoor air, and makes the outdoor air flow through the total heat exchanger 20 for heat exchange to have a temperature close to that of the room, and then flow into the room through the air supply unit 22 . In addition, the ventilation system drives the exhaust fan, so that the indoor air flows through the exhaust part 24 and the total heat exchanger 20, and is exhausted to the outside.

[0042] The above-mentioned air cleaner 10 preferabl...

Abstract

The present invention relates to indoor air quality control equipment by utilizing ventilation system and its method. Its control equipment includes ventilation system and air purifier. Said ventilation system can be used for sucking outdoor air and discharging indoor air to implement indoor ventilation, and the air purifier can utilize filter system to raise indoor air quality. Its control method utilizes the devices of carbon dioxide sensor, dust sensor and gas sensor, etc. and adopts the measures of detecting carbon dioxide concentration and detecting indoor air pollution extent, etc. Besides, it also provides the concrete steps of said control method.

Description

technical field [0001] The invention relates to an indoor air quality control device and method using a ventilation system. Background technique [0002] The air in the closed space, under the respiration of the indoor personnel, gradually increases its carbon dioxide content as time goes by, which affects the breathing of the indoor personnel. [0003] Therefore, when many people gather in small spaces such as offices or vehicles, it is necessary to replace indoor polluted air with outdoor fresh air at any time. At this time, a ventilation system is usually used. [0004] The ventilation system draws in outdoor air by driving the air supply fan, and cools or heats the inhaled outdoor air through a total heat exchanger to make its temperature close to the indoor temperature. Then it is supplied to the room through the air supply unit. In addition, by driving the exhaust fan, the indoor air is sucked in through the exhaust part, and the indoor air is discharged to the outs...
