環境箱用途：
Application of environmental chamber
環境箱可以提供標準的測試環境（如指定的溫度、相對濕度、空氣置換率和氣流速度）或模擬真實的室內環境，並測試各種室內材料和產品的污染物釋放率和釋放特性，進而可以：
Environmental chamber can provide standard test environment (such as appointed temperature, relative humidity, air exchange rate and air velocity) or simulate real indoor environment. It can be used to test the emission rate of contaminants from various indoor materials and products and the emission features so as to further:
l 確定環境變量對材料和產品釋放率和釋放特性的影響；
l determine the influence of environment variables on the emission rate and emission features of materials and products
l 根據釋放特征劃分材料和產品的等級；
l graduate materials and products according to their emission features
l 開發和驗證預測室內空氣污染的模型；
l develop and verify models used to predict indoor air pollution
l 根據室內污染物數據或預測模型對室內空氣質量（IAQ）進行評價；
l value indoor air quality (IAQ) according to indoor contaminant data or prediction models
環境箱的測試原理：
Test principles of the environmental chamber
環境箱測試污染物釋放的過程可以概述為：將材料和產品或其樣本置於測試箱中，根據需要調節箱中的溫度、相對濕度和空氣置換率等環境條件；在環境箱的排氣口或內部取樣；采用適當的方法分析氣體樣本，識別主要的污染物及其濃度隨時間的變化；然後根據測量的濃度確定材料和產品的釋放率和釋放特性。
The process for the environmental chamber to test the emission of contaminants can be summarized as: put materials and products or their samples into the test chamber, and then adjust the environmental conditions such as temperature, relative humidity and air exchange rate inside the chamber according to requirements, and then take samples at the air outlet of the environmental chamber or from the inside, and then adopt proper methods to analyze the air sample so as to identify the main contaminants and changes of their densities with times, and finally determine the emission rate and emission features of materials and products according to the tested densities.
