Description

technical field [0001] The invention relates to a gas parameter testing system, in particular to a multi-channel gas parameter testing system. Background technique [0002] At present, in the fields of industrial production and scientific research, it is widely necessary to test the influence of various parameters on the target value. For example, CFD (computational fluid dynamics) technology in the field of heating, ventilation and air conditioning (HVAC) is attracting more and more attention from people in the industry because of its economical, fast and intuitive features. With the development of computer technology, CFD technology is also playing an increasingly important role in the field of HVAC. But at the same time, due to the limitation of the theoretical basis of CFD itself, the calculation results of CFD need to be verified by experimental test data to improve the calculation model. [0003] In the process of testing, commonly used measuring instruments include ...
