System design

Designing successful open loop ground source heat pump systems requires an integrated understanding of the three key design elements:

• Ground load design
• Borehole design
• Heat exchanger design

The system designer must understand the rate of thermal energy dissipation or replenishment beneath the site in order to ensure that the system will not suffer operational problems due to interference effects.

Numerical heat transport models are developed by zenithgeothermal’s team of numerical modellers in order to define the maximum sustainable thermal load that can be applied to or taken from the groundwater system.

Good borehole design is essential to maximise yields and minimise the risk of problems such as sand ingress or borehole collapse and to integrate with the wider system design to avoid issues at the contract interface.

Zenith International and Loopmaster (Europe) have extensive experience in ground source heat pump system design and provide vital input to any geothermal based building services design team.
