Either in hot summer home, shopping mall or bus subway cannot leave the air conditioner, air conditioner contains many sensor, the temperature sensor and humidity sensor is necessary, now with the research and development products, many brands will reduce the dust sensors embedded in air conditioner, why want to dust in air conditioning units built-in sensors?What are the advantages of the built-in dust sensor in the air conditioner?
What is a dust sensor
The dust sensor, also known as PM2.5 sensor, can be used to detect the dust concentration in the air around us, i.e., the size of PM2.5.Aerodynamics refers to particles less than 10 m in diameter that can enter the alveolar area as respirable dust.Dust particles with a diameter of more than 10 m are mostly deposited by impact and deposited in the nasopharynx during inhalation, while dust below 10 m can enter the deep part of the respiratory tract.Most of the dust deposited in the alveoli is dust less than 5 m.
Advantages of built-in dust sensors in air conditioners
Everything has two sides, have a bad side, air conditioning air conditioning in the cold wind blowing at the same time, also the bacteria in the air, dust and other microbes converged on the indoor machine of fin, time is long can produce bacteria, parasites, such as mite bug to spread by blowing again in the air, will pollute the air, people often get sick because of this, so the dust in the air conditioning units built-in sensors can be to monitor PM1.0, PM2.5 and PM10 particles at the same time, also installed the dust sensor based on real-time monitoring of the air conditioning data to update the indoor air dust, the dust concentration of indoor environment control in a reasonable range,Avoid health hazard caused by excessive dust concentration.In addition, the air intake of the fan can be controlled based on the monitoring data of dust concentration to meet the requirements of energy saving and environmental protection.
Laser PM2.5 Dust Sensor
Add dust in air conditioner sensors to help consumers away from the dust pollution, will become a new trend in the future technology, and is also a new development direction of air conditioner, the built-in dust sensors for air conditioning how to choose the small make up recommend Luftmy laser dust sensor series, using Mie Mie spherical particle scattering principle, namely the laser sensor using laser the light scattering in the suspended particles in the air, the photoelectric detector in a certain way within the scope of collecting scattering intensity, will receive the scattering intensity linear converted into voltage, and then into a data processing system,The data processing system processed the data according to the program prepared in advance according to the michaelis scattering theory and obtained the equivalent particle size and the number of particles with different particle sizes per unit volume.In addition to being embedded in air conditioners, the laser dust sensor can also be installed in fresh air systems, vacuum cleaners, air purifiers and other devices that need to monitor the concentration of PM2.5 particles.
