Ground-source heat pumps.

Summary

The ground is a heat sink/heat source, which is, similar to outside air, almost not limited by availability. Limitations can be the ground temperature in very hot regions and the composition of the ground. In cold regions with mainly heating demand, ground-source systems are dominating the market, but the share of systems for cooling is also increasing. A completely different use of the ground happens in the case of large systems with both cooling and heating demand: natural recharging of the ground no longer works, and an excellent solution is to use heat removal from cooling operation. The ground becomes a store, and the temperature changes in this store are the result of heat extraction/heat removal over the year. Taking all these aspects as a whole, highly efficient systems can be realised.
