AC Selection & Energy Calculator | Sinclair

AC Selection & Energy Calculator

Quick-size a Hi-Wall split line-up or a Multi-Split system from the Sinclair range, and compare estimated running cost between the two before you decide.

Operating assumptions

All units in this range operate on 230V single phase.

Hi-Wall quick selection

Split lines
Each line is a matched indoor + outdoor set. Capacity check uses power × EER; running cost uses measured power draw (V × A) only, per line, summed across all lines.

Multi-Split quick selection

Indoor units
Outdoor condensing unit is auto-selected as the smallest CDU whose capacity covers the combined indoor load, capped at 25% diversification. Running cost uses the outdoor unit's measured power draw only.

Hi-Wall Multi-Split
Add units to both sides to compare running cost.
Product data (EER, rated current, capacity) is drawn from the Sinclair Hi-Wall, Cassette, Ducted and Multi-Split CDU ranges and embedded in this page's script — extend the CATALOG arrays to add new stock codes. Figures are for comparative sizing and running-cost estimation only; confirm final selections against full datasheets. © Sinclair — distributed by Metraclark.
