System for measuring emitting characteristic of building materials in indoor environment and environmental chamber of system

The invention provides a system for measuring the emitting characteristic of building materials in an indoor environment and an environmental chamber of the system.The emitting characteristic of the indoor building materials can be precisely measured, and the concentration of SVOC gas phases and particle phases in the building materials can be detected.The environmental chamber comprises a shell, a generating chamber and a sampling chamber, wherein the generating chamber and the sampling chamber are arranged in the shell in a sealed mode.The generating chamber and the sampling chamber are isolated from the shell, and an interlayer is formed.A heating device is arranged in the interlayer.A control device of the heating device is arranged on the shell.The generating chamber and the sampling chamber are connected through two horizontally parallel sampling channels.A chamber cover capable of being opened, an air inlet for supplying air, and a lead opening for being connected with an external probe are arranged on the generating chamber.Particle phase collecting devices and/or gas phase collecting devices mounted on the sampling channels are arranged in the sampling chamber.The free ends of the sampling channels are arranged to penetrate through the rear portions of the sampling chambers.Temperature sensors are arranged in the generating chamber and the sampling chamber respectively.The output ends of the temperature sensors are connected with the input end of the control device.
