Project Name	Technical parameters and requirements
Test cabin volume	30m³.
Test cabin size	3.5 m×3.4 m×2.5 m = 29.75m³Allow ±0.5m³Deviation.
temperature and humidity	Standard temperature（23±2）℃, relative humidity（50±10）%The temperature is18℃~28Adjustable between ℃, relative humidity within30%~70%Adjustable between them.
framework	76 mm×44 mmStainless steel profiles, installed on the floor.
wall	Using thickness as5mmFloatation flat glass.
floor	Using thickness as3mmStainless steel plate, sturdy and beautiful.
roof panel	Using thickness as3mmStainless steel plate, sturdy and beautiful.
sealing material	Use silicone rubber strips and glass sealant.
Sampling tube material	Stainless steel or polytetrafluoroethylene should be equipped with four injection ports and four sampling ports. The length of the import tube should be（400～500）mm.
ceiling fan	Stainless steel ceiling fan with a diameter of1.4mSan Ye. Ensure that the mixing degree inside the environmental chamber reaches80%The above.
circulating fan	（500-700）m³/h, diameter20cmInstallation location: off the ground1.5m, away from the back wall0.4m.
Circulating purification module	Circulating purification module, which can quickly（<5min）Purify the air at the high concentration limit in the test chamber to meet the Indoor Air Quality Standards（GB/T 18883）The air; Can quickly（<5min）Purify the air with normal concentration inside the test chamber (equal to the concentration outside the chamber) to meet the requirementsGB/T 18801Air with standard background concentration requirements.
exhaust fan	ventilation rate900 m3/h.
airtightness	The air leakage rate inside the test chamber should be less than0.05 h-1. (Natural attenuation experiment)
Mixing degree	greater than80%.
Adsorption test	The natural decay rate of toluene is less than0.05h-1. (Natural attenuation experiment)
Background concentration	Equipped with a circulating purification module, it can quickly process the background concentration to below the national standardGB/T 18883The requirements in.
data acquisition and processing	Collecting electronic instrument signals and concentrating them into computer output, usableexcelTable processing yields standard test results, saving testing costs and improving testing efficiency.
