Intelligent Multi-point Temperature Measurement System Data Processing Platform And The Establishment Of The VAV System Of The Experimental Study

VAV system is a new kind of air condition system which makes use of changing the amount of air to adapt to variable load inside the district. It not only provides us comfort, but also has the character of obvious energy-saving, so it owns large application.Detecting the environment temperature accurately is the key technology to ensure that the VAV control system adjusts the temperature successfully. According to the character of the multi-channel temperature measurement in the VAV system, the digital temperature acquisition and 1-wire technology are used in this paper, and it predigests the anterior circuit and improves anti-jamming ability of this system effectively.According to VAV laboratory experiment with the features, combined with the actual conditions, design VAV laboratory, Drawing floor plans and site structures laboratory. The same time help the College to do more intelligent temperature measurement system construction, installation, commissioning.Butt received the PC data set MATLAB software processing platform, surface temperature measurement in the field to show three-dimensional. The more intelligent temperature measurement system and the use of the thermocouple in the results, pointing out the gap. And the different conditions, different air situation (diffuser, strip sent drafts displacement ventilation) is the experimental data into a unified performance 3D indoor temperature, air distribution for the corresponding effect of the comparison.Experimental results show that temperature changes with the actual organization of the air, are all in the form of heat source added. The results also show that the temperature of temperature effects.
