FAQs

A double line diagram is a two-dimensional drawing that can be used for an HVAC system. It shows how the pipes are connected, how the ducts are run and the different zones in which each component operates.

A double line diagram in HVAC works by providing natural ventilation through the use of a fan that pushes air into the heating and cooling system. The temperature of the room is regulated by this device and it can be adjusted by turning knobs located on the front panel.

The benefits of double line diagrams include:

  • Easier to understand
  • Simpler to read and follow
  • Provides better overview
