Application of dust sensor in air conditioner

2017-08-29 Source:
Air conditioning has now entered every household. Air conditioning can bring us warm in winter and cool in summer. Now many people can't leave the air conditioner. Whether it's work or going home from work, the first thing to turn on the air conditioner is to turn it on. We all know that there are many sensors in the air conditioner, among which the temperature sensor and humidity sensor are the most important. They play an important role in air conditioning. Now the dust in urban environment is increasing day by day, many air conditioning manufacturers have tried to add dust sensors to air conditioning.

It has become a new trend to add dust sensor into air conditioner. PM2.5 can monitor the indoor and outdoor dust concentration in real time. After adding the dust sensor, the air conditioner can update the indoor air timely according to the dust data. In addition, the fan inlet air volume can also be controlled based on this, so as to meet the requirements of energy conservation and environmental protection. In this way, the dust concentration in people's environment will not be too high to endanger people's health.

    Working principle of dust sensor in air conditioner

The silver ion electrostatic precipitator for air conditioning will automatically start the silver ion electrostatic precipitator when the dust level in the air is too high. The dust and dust will be absorbed to the dust collecting plate and filter screen by high-voltage electrostatic technology. The deodorization filter screen adsorbs and decomposes harmful gases and odors. Silver ion has strong antibacterial activity, destroying the inherent components of harmful microorganisms and killing them. It can realize the triple purification of dust collection, odor removal and sterilization. The dust sensor is sensitive to capture extremely fine dust particles (cigarette smoke, etc.) in the air, and displays the air dust level on the display screen.

Adding dust sensor to air conditioner to help consumers keep away from dust pollution will become a new technology trend and a new development direction of air conditioner. I believe that in the next few years, all air conditioners will be installed with dust sensors, which is also a business opportunity.
