CADR purification chamber, CCM test chamber

Test chamber

Unless otherwise specified, the test chamber shall comply with the requirements of QB/T5364-2019 for 3m, 10m ', 30m', and 81m test chambers

A device used to determine the limited enclosed space and standard test conditions of a purifier's ability to remove target pollutants from the air.

1、 Product Description:

The environmental test chamber can simulate indoor environments and is an important tool for detecting and researching indoor air purification products. At present, foreign environmental chambers mostly focus on studying the release patterns of pollutants from indoor decoration materials and products, with little research on the detection of air purification products.

This product 30m³Large environmental test chamber, with an inner wall of8mmFloat glass, the sealing material is a special sealant with low adsorption. The air purification system inside the cabin is equipped with a multifunctional air filter, which can remove both particulate matter and chemical pollutants such as formaldehyde, benzene, and ammonia. Moreover, the temperature and humidity control of the cabin is precise, the airtightness is good, and the background concentration of the cabin is low.

1Overview of Environmental Test Cabin

The overall structure of the environmental test chamber mainly consists of the cabin body, air purifier and temperature and humidity control system, exhaust duct, circulation duct, air sampling system, and pollution source generation device. The basic structure is shown in the following figure:

IIThe main components of the test cabin system

2.1 The testing room is equipped with 30 Cubic meter testing chamber, cabin background control system, gas pollutant generator, and testing instruments（customer-supplied）The temperature and humidity control system, etc. The size of the laboratory in the environmental test chamber is:3500D×3400W×2500H mm

2.2 observation room

Used for observation during the experimental process,Storage of test prototypes and experimental records.

2.3 Test cabin

use 304 Made of stainless steel and glass, thirtyCubic meter capacity.

2.4Glass cabin floor(Pre embedded power supply/Grounding line),0.8 mmthickSUS304Stainless steel material; Top ceiling0.8 mmthickSUS304Stainless steel material.

2.5The glass cabin adopts stainless steel square tubes as reinforcing ribs and8 mmA wall made of float glass.

2.6Fan the door, the size of the door opening is2000Hx800WmmThe sealing adopts tetrafluoroethylene strips+sealing strip(HBC1079Food grade sealant approved by the European UnionROHSEnvironmental standards, approved by the European UnionREACHChemical regulatory standards, approved by the United StatesFDAFood hygiene standards).

2.7 Homogeneous fan,1.54mDiameter ceiling fan.

2.8 Four sampling holes with a diameter of ￠ are installed on the same plane as the door for injection and sampling6mm,With valve,Height distance mask1.0-1.2m, spacing10cmThere are interfaces inside and outside the sampling port that can be matched with PTFE sampling tubes of the required length, allowing the sampling points to be located at different sampling positions. Install two diameters in the opposite direction to the door direction10mmInjection hole, height above ground1.0-1.2mThere are interfaces inside and outside the sampling port that can be matched with PTFE sampling tubes of the required length

2.9 Top lighting,fluorescent lamp40Wｘ2

2.10 Test cabin power supply/control system

2.11 Variable frequency stabilized power supply,power3000W,frequency 40～70HZ,voltage 100～300V(Customers can configure it themselves)

2.12 Purifier operation status detection:Voltage, current, power, power factor. (Customers can configure it themselves)

2.13 operation console,Control the main power supply, background purification system, lighting, ceiling fan, and test startup/Stop waiting

Temperature and humidity control system: PIDControl and balance temperature and humidity control system(BTHC),This method refers to the control system using a set temperature point toPIDAutomatically calculate the output results to control the refrigeration system, providing continuous or intermittent cooling capacity
