Multifunctional environment simulation cabin

Abstract

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.

Description

technical field [0001] The invention relates to a laboratory equipment; in particular, to an environment simulation laboratory equipment. Background technique [0002] With the improvement of people's living standards and the increasingly serious environmental pollution, people's demand for air purification products that can eliminate a variety of environmental pollution is increasing day by day; the purification effect of air purification products usually needs to be tested and verified in different polluted environments. [0003] Most of the multifunctional environmental simulation cabins in the prior art are small multifunctional environmental simulation cabins with a volume of about one cubic meter. Single, very few can be used for air purification product testing. [0004] The national standard GB / T18801-2008 "Air Purifier" clearly states that an environmental simulation cabin with a volume of 30 cubic meters is required to test the air purifier, and it is required to ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to propose a multi-functional environmental simulation cabin to avoid the single function of the environmental simulation cabin of the prior art and the large deviation between the air purifier test and the actual situation. It can not only simulate a closed environment, but also simulate indoor environments with different degrees of pollution, and can simulate a dynamic environment simulation cabin with a controllable fresh air ratio. It is an important experimental platform for testing and researching the performance of air purification products.
