| Project description |
In the part of this project for which the University of
Applied Sciences is responsible, the year-round use of an earth
probe system is to be examined with the goal of reducing the
total costs by increasing the efficiency and the runtime. In
the experiments, a 5 kW ammonia/water diffusion-absorption
chiller (DAKM) with two 80m-long earth probes, each with
different borehole filling material will be used. This pilot
machine will be used in combination with air circulation
heaters/air-conditioning units as a chiller in the summer and
as a heat pump in the winter to cool/heat a laboratory. The
instrumentation already present in the building enables
detailed measurements to be taken of the effects of the
different applications such as re-cooling, direct cooling and
heat pump operation on the fluid mechanics and heat transfer
processes in the probes and the resulting energy-abstraction
capacity. |
