Hybrid System Design

The Hybrid System Design toolset is deeply integrated into GLD and spans across the heat exchanger design modules, the loads modules, the life cycle module and the heat pump module. This integration enables a designer to quickly shift design loads from unbalanced to balanced and to optimize loopfield design based on an accurately split geothermal/hybrid loads profile. The toolset significantly increase design efficiency and reduces installation costs. Furthermore, with the ability to perform automated precision peak load shaving on 8760 hourly loads profiles in real time, GLD makes it effortless for a designer to understand when the loopfield will be in use and when the hybrid systems will be active. This information is invaluable for conventional equipment sizing and operational analysis.

Some of the more powerful features in the Hybrid Design toolset include:

  • Design Day, Monthly and Hourly Hybrid Design Modes
  • Precision Peak Load Shaving
  • Intelligent Total Monthly Load Shaving with Monthly Loads Data Sets
  • A Suite of Hybrid Visualization Tools
  • Hybrid Life Cycle Costing
  • Hybrid Summary Panel Which Highlights the Peak/Total Load Balance
  • Hybrid Loads Profile Export Function (monthly, hourly)
  • Powerful Interface for "What if" Hybrid Modeling
