Environment testing device

Abstract

The invention relates to an environment testing device. The environment testing device comprises an environment testing system, a constant-temperature constant-humidity air treatment system, an air purifying system, a signal processing system and a display device, wherein the environment testing system is used for testing a harmful substance; the constant-temperature constant-humidity air treatment system is used for controlling the internal temperature and humidity of the environment testing system; the air purifying system is used for conveying clean air to the environment testing system; the signal processing system is used for processing temperature and humidity signals which are detected by the constant-temperature constant-humidity air treatment system; the display device is used for displaying signals which are transmitted by the signal processing system; the air purifying system is connected with the environment testing system through an air inlet of a testing outer chamber; the constant-temperature constant-humidity air treatment system transmits a detected analog data signal in the environment testing system to the signal processing system; the signal processing system converts the analog data signal into a digital signal; and the display device displays the digital signal. By adoption of the environment testing device, the temperature and humidity of the testing outer chamber and a testing inner chamber in the environment testing system can be accurately controlled, a real indoor environment is effectively simulated, the release rate and release characteristic of a pollutant are tested, test data are obtained, and a test model is established.

Description

technical field [0001] The invention relates to an environmental testing device, in particular to a harmful substance environmental testing device with four small-sized inner chambers. Background technique [0002] In recent years, environmental pollution has become a common concern of all countries in the world. Studies have shown that indoor air pollution has become an "invisible killer" that endangers human health. The United States has classified indoor air pollution as one of the five major environmental factors that endanger human health. The World Health Organization The organization also listed indoor air pollution together with high blood pressure, high cholesterol and obesity as the top 10 threats to human health. According to the current detection and analysis, the pollution of consumer products such as indoor building materials and furniture is the main aspect causing indoor air pollution. In order to study the problem of indoor environmental pollution, and to s...

[0003] Chinese patent CN201291138Y discloses an environmental test chamber, including a jacket and a test chamber liner arranged in the test chamber jacket, and a hatch on the top, the air intake pipeline communicates with the inner tank, and the other end extends from the test chamber jacket The outlet is connected to the clean air source. The structure of the test chamber is a single large chamber structure. It is difficult to maintain uniformity between the control sample and the test sample during the test, and the control device is not easy to grasp
