[edit]
Description A closed water loop providing condenser water to zone cooling units (number of units dependent on scale of structure).
Advantages
  • Extremely effective if considered in structure design phase
  • Increased leasable space
  • Floor ceiling heights can be lower
  • Individual control of zones
  • Fully automatable
  • Simple design
Disadvantages
  • Loop circulating pump must operate constantly
  • If not considered in structure design, integration is difficult
  • Design is sensitive to error
  • Heating capacity may not be sufficient for large scale.
Characteristic features
Application barriers
  • As the system must be fully committed in the design phase of a structures life it is often considered too much for a HVAC system.
