主　　题：Heat Pump Measuring Design TRT Borehole Thermal Conductivity Control System 

摘      要：The paper deals with problematic of Thermal Response Test (TRT) system. The correct design of borehole heat exchangers for ground source heat pumps and the knowledge of rock massive thermal properties is paramount. For small heat pumps systems these parameters are estimated. However, for larger objects the thermal conductivity should be measured on site. Thermal Response Test is an useful tool for thermal conductivity estimation. This test is instrumental to find out a response of rock massive in which a heat pump might be installed. The paper describes basic principles of TRT and its utilization for heat pump boreholes design.
