This equipment is mainly used to evaluate the removal ability of household air purifier to one or more pollutants in ambient air, such as particulates, gaseous pollutants, microorganisms, etc. The environmental test cabin can simulate the polluted indoor environment more realistically, and can evaluate and test the parameters of the air purifier, such as the clean air volume (CARD), cumulative purification volume (CCM), purification energy efficiency, applicable area and purification life. At present, this product has been widely used in quality supervision and inspection departments, air purifier manufacturers, and relevant scientific research departments to test air purifiers.
30m ³ The development of the test chamber involves many disciplines and specialties such as air conditioning, materials, biology, chemistry, machinery, electricity, etc. It is a complex systematic project. Different from the operation of the high and low temperature damp heat test chamber, the constant temperature and humidity air conditioning unit directly exchanges temperature and heat star with the internal circulation of the risk test chamber [4], 30m ³ The test chamber belongs to a highly enclosed test chamber [5]. After the test, it cannot conduct moisture heat exchange with the constant temperature and humidity air conditioning unit. According to the national standard requirements of GB/T18801-2015 Air Purifier, 30m ³ The test cabin is designed as a nested inner and outer cabin, mainly composed of the inner and outer cabin body, air purification system, temperature and humidity control system, air circulation system, data monitoring system, etc.
