What is an air purifier test chamber?

1. Technical background of air purifier test chamber:

Due to the increasingly serious domestic air environment pollution, air purification products are growing explosively, the public demand for air purification products is growing, such as air purifiers, the demand for equipment and instruments for energy efficiency testing of air purification products will also increase, therefore, there is the invention of the air purifier performance test chamber.

2. The brand model: Huanyi instruments

3. The technical requirements of air purifier test chamber:

GB/T 18801-2015 "air purifier" in the test air purifiers need to use the volume of 30 m ³ environmental chamber, the requirements of the chamber wall using float plate glass, the bottom of the use of stainless steel plate, the top of the use of metal composite panels. Specific requirements are as follows:

(1)Test chamber volume: 30 m³

(2)Test chamber internal dimensions: 3.5 m * 3.4 m * 2.5 m, allowing ± 0.5 m ³ deviation

(3)Frame: aluminium profile or stainless steel

(4)Wall: float plate glass with a thickness of 5 mm or more or stainless steel with a thickness of 0.8 mm or more

(5)Floor: stainless steel plate with a thickness of 0.8 mm or more

(6)Top plate: stainless steel plate or similar material metal composite plate

(7)Sealing materials: silicone rubber strips and glass sealant

(8)Stirring fan: diameter of about 1.0 m ~ 1.5 m, three blades

(9)Circulation fan: 500 m³/h~700 m³/h, diameter 20 cm, installation position: 1.5 m from the ground, 0.4 m from the back wall

(10)Air tightness: the number of air changes is not more than 0.05 h^-1

(11)Mixing degree: more than 80%

4. Cleaning method of air purifier test chamber:

Clean the optics daily or as often as necessary.

Clean all horizontal surfaces daily.

After 5 days of use, mop the floor with a wet mop.

After 20 days of use, clean the inside of the bin.

If necessary, spray antistatic agent after every 5 days of use or frequently to ensure good sensor grounding and data logging.

Particulate matter, gaseous pollutants, microorganisms detection can not be carried out continuously, should be cleaned first test chamber, and then the next pollutant detection, in order to prevent mutual influence.

5. Programme sharing of air purifier test chamber:

(1)Programme details: air purifier performance test chamber for the vertical rectangular lacquered steel cabin, vertical rectangular lacquered steel cabin is equipped with two mirrored stainless steel liner, two mirrored stainless steel liner up and down and were equipped with an independent hatch, the two mirrored stainless steel liner are connected to the pollutant generator and the gas source chamber, the two mirrored stainless steel liner are equipped with frequency converter fans, frequency converter fans are equipped with a porous plate at the air outlet. The air outlet of the frequency conversion fan is equipped with a porous plate, and the two mirrored stainless steel inner liner is equipped with a sensor group consisting of a temperature sensor, a humidity sensor, and a pressure sensor.

Two mirror stainless steel liner are installed inside the environment by the ultraviolet light source system, refrigeration system, heating system and pressure regulator module, the sensor group through the programmable logic controller is connected to the environment control module and control the environment control module, the two mirrors do not induce the steel liner, only one of the internal purification material carrier.

The contaminant generator includes a temperature control system, a contaminant generator and piping, and the outlet of the contaminant generator is coated with a biofilm. The hatch is fitted with a Viton sealing gasket on the inside edge of the hatch, a mirrored stainless steel interior and a knob-type lock on the outside of the hatch. The mirrored stainless steel liner also has an aluminium module sampling system with cross-punched sampling ports and standard boreholes.

(2)Programme features:

*Each mirrored stainless steel liner has its own independent hatch, and the hatch switches are independently operated. Mirror stainless steel liner through the role of variable frequency fan to regulate the air speed inside the chamber, the role of the multi-hole plate to ensure uniformity of the air inside the chamber.

*There are temperature sensors, humidity sensors, pressure sensors and other important parts installed in the mirror stainless steel liner, and the special control software programme receives and gives commands through the programmable logic controller. There is a UV light source system installed inside the mirrored stainless steel liner, which simulates the light conditions. Environmental chamber thermostat system by the jacket duct, heating, cooling system coordinated control, control process by the temperature and humidity sensors will be detected from time to time signal value feedback to the programmable logic controller, the preset control programme according to the value of the signal to adjust the system temperature and humidity.

*Pollutant generator to provide Continuous fixed concentration of pollution sources, after the cabin purification materials, after the role of the purification materials, the purification effect of the purification materials is calculated. The air source chamber is the supporting equipment for the environmental chamber of air purification materials, mainly composed of compressor, cold dryer and filtration system, which provides continuous clean air source for the system. Through the strict software control system, it can quickly and accurately make the temperature and humidity in the chamber reach the set value, the UV lamp simulates the conditions required for sample testing, which can reduce the testing error, and the pollutant generator can provide the continuous and stable pollutant concentration.
