Multi-parameter priority divide rules and application of auto-control geothermal system

To keep the auto control shallow geothermal system runs by a right way of safe, effective, saving energy, a Fundamentals of parameter electing and classification must be set up and abide by geothemal designers. In this paper, a Multi-parameter classificate rule was proposed based on analysis of geothemal system control objectives. Achievement of geothemal system control target must based on the achievements of those five sub-goal. They are the first grade: safe control, the second grade: effect control, the third grade: save energy control, the fourth grade: equipment maintain control, and the fifth grade: survey dots control. And, the parameters must to be divided into five priority. Finally,a finished project was analysised, and a improve complete parameter system was established whice including five priority.
