Multi-point distribution is the engineering method used to route refrigerant from a single outdoor unit to multiple indoor evaporators. This is the core mechanism behind our Multi-Zone systems, requiring precise manifold design to prevent pressure drops. In a 42,000 BTU 2-Zone (18k+24k) configuration, the distribution must be perfectly balanced to ensure both units reach target temperatures simultaneously. Installers often utilize Line Set Covers to manage the multiple copper lines that stem from these distribution points. For those requiring even more complexity, the Penta-Zone systems use a 5-port manifold for maximum reach. Ensuring these lines are properly secured with a Wall Bracket prevents vibration and potential leaks over time. It is a complex but highly effective way to centralize power while decentralizing comfort.
