Ground coupled heat pumps with seasonal cold storage.

Author(s) : SANNER B.

Summary

In addition to the use of reversible ground source heat pumps, as known in particular in North America, in many cases direct cooling from the ground could be applied, without running a refrigerant cycle. In this way cold produced in wintertime can be used for cooling in summertime, which is "seasonal cold storage". Some pilot plants are operational, two systems in Germany (Düsseldorf and Linden) are monitored and under investigation. Direct cooling requires advanced cold distribution devices for higher temperature levels, as cooling ceiling or cooling panels. System concepts optimized in respect to all components (ground heat exchangers, heat pumps, cold distribution) allow primary energy savings as well as minimized CO2-emissions, in particular in the cooling mode.
