Application

  • Hydraulic heating and cooling installations

Fast and intuitive configuration of HVAC installations:

  • Fast model-building using the Base Circuit Methodology
  • Re-use of concepts and models via own models library or the Hysopt Inspiration Library

  • Specific circuits for hybrid generation
  • Design of installations with satellite units ( HIU, Heat Interface Unit), in accordance with DIN 1988-300 (2012)

Model validation:

  • Reporting inconsistencies in the model, incomplete model and supervision
  • Reporting unrealistic parameter input

System check, troubleshooting

  • Reporting conceptual design faults (interaction of pumps, missing balance valves, incorrect combination of hydraulic circuits…)

Canvas management:

  • Connecting different canvasses to keep a good overview in large projects

Floor plan:

  • Read in floor plans (.pdf and .dxf) to scale
  • Implement end units
  • Automatic pipe length generation

Plus:

  • Very fast and flexible updating of design criteria, both comprehensive and differentiated or via tags
