The invention relates to environment
simulation laboratory equipment, especially to a multifunctional environment
simulation cabin comprising a cabin body, a PLC
control system installed at the outer wall of the cabin body, an air circulation and purification sub
system for air circulation and purification inside the cabin body, a new air conveying sub
system for inputting new air into the cabin body, a target
gas concentration control sub
system, and a pressure-control exhaust system. The PLC
control system is connected with and controls a plurality of function sub systems by signals, thereby realizing
simulation of the environment with different temperatures and
humidity and target gas concentrations inside the cabin. According to the invention, an external circulating air hose is provided with different purification device interfaces to installed tested purification devices, so that
dynamic testing of tested purifiers on the circulating air hose as well as testing of static environments with different monitoring gas concentrations can be simulated. Testing demands of various purifying devices like an adsorption type purifying device, a
photocatalysis type purifying device, or a
plasma-technology-based purifying device can be satisfied.
