A double line diagram helps contractors plan out the installation of systems while taking into consideration that they may need to cut through walls or floors.
A double line diagram is used by an HVAC technician to demonstrate these components through a step-by-step process that shows the beginning, middle and end of how these various components function together. An HVAC technician will use this diagram in his or her work as it allows him or her to communicate with customers about how different components function together and impact the overall performance of an appliance. Both large businesses and individuals would benefit from using a double line diagram while they are working on an appliance installation or repair project.
