自助餐 / 火锅 / 大型餐厅 特有的转换难点

• 01 · Per-table induction electrical load

  A hot-pot table with 2 induction zones at 1,800W each = 3,600W per table. A 40-seat dining room at 2 seats/table = 72 kW of induction-only load, separate from kitchen + HVAC + lighting. That requires service upgrade or sub-panels routed through the floor — typically $20K–$60K depending on existing service capacity.

• 02 · Per-table exhaust + downdraft

  Tabletop grills (Korean BBQ) need exhaust at every table — overhead hoods, or downdraft systems listed for the purpose (IMC §507.1; NFPA 96) — plus grease ducts, an exhaust fan and make-up air; downdraft ducts run under the floor and suit slab-on-grade, while overhead hoods avoid cutting an upper-floor slab. Hot-pot tables (boiling broth) mostly add steam and heat, so ask the city whether it wants table exhaust or lets the HVAC design carry that load (IMC §507.3).

• 03 · Buffet line sneeze-guards + temperature

  The FDA Food Code requires food on display to be protected by food guards (sneeze guards), display cases or other effective means (§3-306.11), with hot holding at 135°F or above and cold holding at 41°F or below (§3-501.16). Inherited cafeteria tables rarely hold those temperatures, so spec NSF-certified hot/cold wells with built-in thermometers, not standalone chafers + ice.

• 04 · Dish-room scale + 3-comp sink size

  A 150-seat buffet can push 1,500+ dishes per service, which takes a flight-type or rack-conveyor dishwasher (not a single-rack undercounter) with three-phase power and a booster heater sized from the machine's spec sheet. Add a 3-compartment sink for pots (FDA Food Code §4-301.12) and room to match — about 200 sq ft is typical, and inherited dishrooms are often undersized.

• 05 · HVAC for large dining + per-zone control

  A 150-seat dining room with active hot-pot tables generates massive sensible + latent load. A single-zone rooftop unit cannot follow variable occupancy (slow lunch vs packed dinner). Plan 3–5 separate zones (e.g., VAV boxes), typically $25K–$50K, versus the call-backs from a one-zone system that runs cold in corners and hot at the entry.
