The high closure of modern houses makes life more comfortable, secretive and energy-saving, but carbon dioxide and water vapor produced by human breathing; Formaldehyde and MOM produced by building materials, homes, curtains, etc.; Dust produced by clothes and bedding; The smell of human body, smoking and cooking will accumulate indoors. If windows are opened for ventilation, the intensity of outdoor wind, the temperature and humidity of the air are often unsatisfactory; if you can not carry out good ventilation, will cause indoor air turbidity, easy to mold, tick.

The fresh air system is simply to discharge indoor polluted air to the outside, and at the same time to send outdoor fresh air to the room, is an air circulation exchange system. Through the circulation of air exchange to achieve the purity of indoor air, to protect human health.

In short, the role of the fresh air system mainly has the following points:

(1) Provide fresh air. 365 days a year, 24 hours a day to provide fresh air for the room, do not open the window can also enjoy the fresh air of nature, to meet the health needs of the human body.

2. Remove harmful gases. Effectively remove the smell of oil smoke, CO2, cigarette smell, bacteria, viruses and other unhealthy or harmful gases, can avoid the family children, lovers and the elderly by second-hand smoke hazards.

3. Anti-mildew and odor removal. The indoor humid dirty air discharge, root out odor, prevent mildew and bacteria, help to extend the service life of the building and furniture.

4. Reduce noise pollution. No need to endure the troubles caused by opening windows, making the room quieter and more comfortable.

5, dust. Avoid opening windows to bring a lot of dust, effectively filter outdoor air, and ensure access to the room...

If the fresh air system has been running at full power, the energy consumption is still very high, and high-power operation will bring some noise, but it is not appropriate to run at low power all the time. After all, it may lead to indoor air turbidity, CO, CO2, VOC and other gas concentrations are too high, endangering human health. Therefore, it is necessary for the fresh air system to monitor the concentration of CO, CO2, VOC and other gases in the indoor environment in real time, and adjust the operation of the fresh air system according to the concentration of these gases, so that the low energy consumption and comfortable environment coexist.      

CO Gas Sensor TGS5141

* Ultra-small

* Can be battery driven

* High selectivity/repeatability for carbon monoxide

* High linear output characteristics for carbon monoxide

* Easy calibration

* Long service life

* Get UL certification

* Meet the requirements of UL2034, EN50291 and EN54-31

The TGS5141 is a battery-driven electrochemical sensor developed by Figaro. A special electrode is used instead of the water reservoir. Due to the removal of the water reservoir used in the TGS5042, its external size TGS5141 reduced to only 10% of the size of the TGS5042. Life can reach more than ten years. Very suitable for monitoring CO concentrations in fresh air systems.

CO2 Gas Sensor Module CDM7162

* Small size

* Low power consumption

* High precision

* Single light source dual wavelength mode

The CDM7162 has the characteristics of small size, low power consumption and high precision. It is a non-dispersive infrared (NDIR) carbon dioxide (CO2) sensor module with superior performance. The module is equipped with a pair of photodetectors and uses unique signal processing technology to achieve long-term stable output. CDM7162 module design is simple, can be easily with the user's product docking. Can be widely used to enhance energy-saving ventilation control, indoor climate improvement.

VOC Gas Sensor TGS2600/TGS2602

* High sensitivity to VOCs and odors

* Low power consumption

* High sensitivity to polluted air

* Long service life

* Simple application circuit

* Small size

TGS2600/TGS2602 are semiconductor principle sensors developed by Figaro. The sensitive elements are composed of integrated heaters and metal oxide semiconductors on alumina substrates. If there is a target detection gas in the air, the higher the concentration of the gas, the higher the conductivity of the sensor. With only a simple circuit, the change in conductivity can be converted into a signal output corresponding to the gas concentration. It has high sensitivity to extremely weak air pollution gases. It is very suitable for monitoring VOC pollution in fresh air system.
