Ground thermal condition evaluating method for geothermal plants, involves using time series in mathematical model for dynamic description of temperature field in ground and for formation of characteristics describing thermal condition

摘要

The method involves measuring temperature and flow rate on a delivery side of a heat pump (2), an electrical work of the pump, and temperature and flow rate between a ground collector (1) and the pump. External temperature is measured. The measured values are stored in a long term storage of a controller- and data acquisition device (4). Time series is used in a mathematical model (11) for dynamic description of a temperature region in a ground (10) and for formation of characteristics describing a thermal condition of the ground in an environment of the collector in the model. An independent claim is also included for an arrangement for implementing a method for evaluating a thermal condition of a ground.
