Abstract
A temperature adjusting device is included with a sand and dust environmental testing system. The sand and dust environmental testing system includes: a circulating air duct, including a contraction section, a test section and a separation section etc.; a main blower; U-type separators and guide vanes, respectively configured at four corners of the circulating air duct. The temperature adjusting device includes: heat exchange pipes distributed in the U-type separators; four groups of guide vanes. Three groups of the guide vanes are configured with heat exchange medium holes and the other group of the guide vanes is equipped with heating device. An electric heater is accommodated in the second contraction section. An intelligent temperature control includes: building a neural network system structure; blended learning training of neural network parameters; PI control; and amplitude limitation processing.
