Ground-coupled heat pumps in Austria.

Author(s) : HALOZAN H., RIEBERER R.

Summary

In Austria, direct-evaporation ground-coupled systems with horizontally installed ground coils are dominating the market. In the case of limited ground area or existing houses, the alternatives are vertical systems, either secondary loop systems with the disadvantages mentioned above or again direct evaporation systems. A new concept is a heat pipe as ground heat exchanger, and due to the fact that in this heat pipe only CO2 without oil is self circulating, no environmental concerns exist. The seasonal performance factor achievable with such systems is similar to that of direct-evaporation systems.
