Since the 2019 COVID-19 epidemic ravaged the world, the virus has continued to challenge and impact people's daily work and life.
At the same time, people have begun to realize the importance of healthy breathing and have begun to create a comfortable and livable living environment. However, traditional air-conditioning products are far from meeting people's needs for high-quality air quality. The new product fresh air conditioner came into being at the right time, and began to welcomed in the market.
According to AVC online monitoring data in Chinese market, the number of brands of fresh air air conditioners increased from 4 in 2019 to 10 in 2021, and the number of models on sale increased from 26 to 123. From a scale perspective, the online sales of fresh air air conditioners in 2021 were 820 million, a year-on-year increase of 492.7%, and the offline fresh air air conditioners were 1.91 billion, a year-on-year increase of 57.4%. In addition, products with sterilization and disinfection functions are also valued by manufacturers.
Compared with traditional air conditioners, fresh air conditioners add fresh air, sterilization, intelligent temperature control, self-cleaning and other functions on the basis of cooling and heating. They can provide users with relatively sufficient oxygenated air through the amount of fresh air. The fresh air volume of the current wall-mounted machine/cabinet machine on the market is maintained at 20~150m³/h .
In order to solve the problems of indoor non-ventilation and turbid air under the condition of internal circulation of traditional air conditioners, fresh air conditioners filter and transport fresh outdoor air to the indoor through indoor and outdoor air exchange, thereby improving indoor air quality and meeting users' needs for indoor air comfort.
Of course, fresh air conditioners cannot be equated with fresh air systems, because there are not only PM2.5 particles but also various types of bacteria and pollen mosquitoes in the air. In a complex air environment, the fresh air air conditioner does not have the three-layer high-efficiency deep filtration function of the fresh air system. It can efficiently filter and purify the air, and continuously provide fresh air 24 hours a day. Moreover, most fresh air conditioners supply air at fixed points and do not have the function of multi-point air supply and return of the fresh air system.
Whether it is fresh air conditioning or fresh air systems, the focus is on the two core requirements of "air circulation" and "air purification". To realize these two functions, it is necessary to integrate temperature and humidity sensors and PM sensors into the corresponding equipment. NDIR CO2 sensors, formaldehyde sensors, ozone sensors monitor air quality in real time, help make fresh air equipment intelligent, and protect a healthy home environment.
In response to the market demand for fresh air systems and fresh air conditioners, MFrontier sensors mainly include MTP50-A NDIR CO2 dual-channel sensor, MPM30 series infrared dust sensor and MPM12-BG laser dust sensor.
The MTP50-A NDIR CO2 dual-channel sensor uses the property of gas molecules CO2 to absorb infrared rays to calculate its concentration.
Features
Dual-channel, strong anti-interference ability, high stability, high precision, high sensitivity, small size, easy to integrate
Application
Air detection, fresh air conditioning, air purifier, fresh air system, in-car air purification
NDIR sensors are suitable for monitoring various types of flammable, explosive and carbon dioxide gases, with long service life and low maintenance costs.
MFrontier MPM30 series PM2.5 dust sensor adopts the traditional infrared optical scattering principle, and its light source is an infrared LED light source, which responds sensitively to particles ≥0.3um.
Features
Strong stability, strong anti-interference ability, high accuracy, low power consumption, automatic temperature compensation and correction
Applications
Fresh air system, Fresh air conditioner, Air purifier, In-car air purification
MPM12-BG Laser PM Sensor
The MPM12-BG laser dust sensor comes with a high-performance MCU. Its structure and circuit are more complex and scientific. Its sensitivity and accuracy are excellent. It can detect 0.3~1.0um, 1.0~2.5um, 2.5~10um particles. It has more advantages in sampling number, data source and algorithm.
Features
Laser scattering detection principle, Real-time monitoring output, Ultra-thin design, Fast response, Small size, Easy installation
Applications
Fresh air system, Fresh air conditioner, Air purifier, In-car air purification
Fresh air fans, fresh air conditioners, and fresh air systems are an inseparable part of the smart home ecological chain. They bring people not only a healthy home environment, but also a high-quality lifestyle. As the basis for smart home control systems, sensors are the nerve endings that support the entire control system. They are of extremely important significance for the collection, transmission, and command issuance of information. MFrontier temperature sensors, gas sensors, , dust sensors and pressure sensors can be widely used in smart home control systems, to create a comfortable and safe home to consumers.
