Defaults reflect this space type, including its typical equipment/metabolic load of ~1,500 BTU/hr. Same engine as the main calculator.

Retail loads stack three things homes don't: door-opening infiltration every few minutes (a glass storefront door can leak a third of the cooled air's worth of heat back in), display lighting (every watt is heat), and variable occupancy. The estimate below uses six average occupants plus lighting/equipment; busy weekend peaks run higher — inverter headroom absorbs them.
Indian shops above ~300 sq ft typically run two splits or a ceiling cassette rather than one big unit — redundancy (one unit failing doesn't close the shop on a May afternoon) and more even air throw across racks. An air curtain over a frequently-opened door pays for itself in one season in hot-dry cities.
A typical retail shop (~400 sq ft) needs about 16,460 BTU/hr — a 1.5 ton unit in moderate US conditions, or two split units in hot Indian conditions (44,300 BTU/hr).
A typical Indian retail shop of ~400 sq ft carries roughly 44,300 BTU/hr in hot conditions — a two split units. Adjust with the calculator above for your exact room and city.
Redundancy and coverage: if one unit fails in peak summer the shop stays open, and two throw points cool aisles evenly. Operating cost is similar at equal total tonnage with inverters.
