<p>A measuring apparatus of thermal conductivity in ground is provided to obtain reliable data and adjust flux of ground heat exchanger by automatically controlling flux and heat flux. A measuring apparatus of thermal conductivity in ground includes a ground heat exchanger(41). The ground heat exchanger is inserted in a hole(40) formed on the ground, measures ground thermal conductivity, and includes pipes(1,1'), a measurement unit, a safety unit, and a data recorder(30). When the ground heat exchanger is inserted in the hole, fluid flows in the pipes of the ground heat exchanger and passes through the measurement unit during circulation. The measurement unit measures data on temperature, flux, power amount, and current amount for calculating the thermal conductivity. The safety unit is installed on the pipes for preventing damage to the pipes. The data recorder records the data measured from the measurement unit.</p> |
