What is a fresh air system

Fresh air system is to filter the fresh outdoor air into the indoor, at the same time the indoor dirty air out of the outdoor, in order to achieve the balance of the system, at the same time replace the indoor air, so as to achieve the closed space of scientific air convection, for your room to add a respiratory system.

How the fresh air system works

The fresh air system consists of main engine, air duct, air outlet, air inlet and other accessories.When the host machine is running, outdoor fresh air is introduced from the window entrance. Under the action of the pressure field formed by the host machine, outdoor fresh air reaches the indoor activity area to meet the needs of personnel activities.The dirty air then passes through the vents and exhaust pipes to the outside.The air distribution method is scientific and reasonable, with the design of low air volume continuously, low noise and low energy consumption during operation, so as to ensure the best air quality.Bidirectional heat recovery indoor air replacement system consists of heat recovery host, air supply pipeline, exhaust pipeline, air supply outlet, exhaust outlet and other accessories.When the main engine is running, fresh air is brought in from the outside and piped into each room.Dirty air is discharged from the exhaust engine through the exhaust duct.When the exhaust passes through the main engine, it exchanges heat with the fresh air to recover, and most of the recovered energy is returned to the room through the fresh air.

What is the use of PM2.5 sensor in fresh air system

One of the most important functions of the fresh air system is to intelligently filter PM2.5 and smog from the air and purify the air.The GDS06 infrared PM2.5 sensor module recommended by Luftmy USES the light scattering principle to monitor and detect dust concentrations in the air.The PM2.5 sensor has a built-in infrared light-emitting diode and a high sensitivity photoelectric receiving sensor.The light emitted by the infrared light-emitting diodes reflects light when it encounters dust. The photoelectric sensor detects the intensity of the reflected light to reflect the concentration of dust in the air.When the dust concentration in the air is too high, the fresh air system will automatically start the PM2.5 filtering function to achieve the effect of purifying the air.
