Geothermal Probe With Heat Pipe Principle

Product Description

Geothermal Probe With Heat Pipe PrincipleIn near-surface geothermal energy generation the thermal energy stored under the Earths surface is used for heating purposes.It demonstrates the operation of a geothermal probe with heat pipe principle. The transparent experimental set-up provides an insight into the closed circuit of the heat transfer: it allows a clear view on the evaporation in the heat pipe, the condensation in the probe head and the reflux of the heat transfer medium on the inside wall of the heat pipe. The set-up also allows to take a closer look at the basic methods applied for determining the thermal conductivity of the surrounding soil of the geothermal probe.Learning objectives/experiments Fundamentals of geothermal energyOperating behaviour of a geothermal probe with heat pipe principleDetermination of the amount of heat that can be dissipated in the heat pipe with variation of the thermal loadVariation of the filling level of the heat transfer medium containedExamination of the radial temperature profile in a sand sample and determination of the thermal conductivityDetermination of the sands thermal conductivity by means of a thermal response testFundamentals and energy balance of a heat pump Specification Demonstration of the operation of a geothermal probe with heat pipe principleHeat pipe made of glass with transparent temperature control jacketWater as a working medium for heat dissipation in the heat exchangerSupply of the working medium via the lab network or via water chillerSimulation of the energy balance of a heat pump
