One fully calculated example for each of our 25 calculators: the inputs, every calculation step and the result, with metric and imperial figures. Open the calculator to run your own numbers, or send the example to a quote request as a starting brief.
Turn stored quantity into volume, floor area and pallet positions.
A frozen packaged-food room receives 20 t/day and holds 14 days at 6 m clear height.
Result: 910 m³ (32,137 ft³), about 152 m² (1,636 ft²) and 414 pallet equivalents.
New frozen store for 500 EUR pallets, no existing fault.
Result: ≈ 61.4 kW required duty (≈ 17.5 TR · 209,600 BTU/h). With 'plant older than 12 years' (+20%) it becomes ≈ 73.7 kW.
A 5,000 m² (53,820 ft²) distribution centre with 12 m (39.4 ft) clear height and selective racking.
Result: About 9,875 pallet positions and 177,750 pallets per year of throughput.
Frozen cold store growing from 10,000 to 18,000 pallets, inbound 220 → 380 pallets/day, 6 doors, 800 kW installed.
Result: New peak ≈ 1,735 kW (≈ 493 TR · 5.9 million BTU/h) — plant upsizing or a second plant is very likely required.
Estimate the cooling capacity, compressor and envelope a supplier must quote against.
A 2,000 m³ frozen room in a hot/arid climate with a 20% safety factor.
Result: About 109 kW, 31.1 TR or 373,000 BTU/h.
A 500 m² chilled room, 6 m high, receives 15,000 kg/day at 22 °C.
Result: 48.91 kW (13.91 TR), planning band 36.35–61.47 kW.
A frozen-store doorway during a warm, humid operating day.
Result: About 10.6 kW average added duty from door openings.
Preliminary NH₃ compressor family for 150 kW at −30 °C evaporating and 40 °C condensing.
Result: About 56.5 kW motor input and a screw-compressor family — not a manufacturer selection.
A 30 × 20 × 8 m frozen room at −20 °C in a 35 °C ambient uses PIR panels.
Result: 125 mm panels with about 19.4 kW transmission heat gain.
600 kW frozen-storage plant in a warm climate (peak ~38 °C), 6,000 run hours.
Result: Ammonia uses ≈ 8% less energy at this climate; in cool climates the CO₂ penalty disappears and the gap reverses.
A 120 kW refrigeration plant with 25 kW auxiliaries needs 24-hour standby power and soft starting.
Result: One 225 kVA generator and about 906 L of fuel for 24 hours.
Blast, IQF, seafood, meat and retail refrigeration examples.
Freeze a 20 t (44,092 lb) fish batch to a −18 °C core in an air-blast tunnel.
Result: About 242 kW plant duty (68.8 TR · 826,000 BTU/h).
An IQF vegetable line freezes 2,000 kg/h for 16 hours/day with product entering at 15 °C.
Result: About 238 kW for 32 t/day.
Whitefish blocks, 30 t/day held 20 days at −25 °C, 7 m building, 35 °C ambient.
Result: ≈ 72 kW holding load (≈ 20 TR · 245,000 BTU/h) and ≈ 667 pallet positions.
Beef carcass chilling, 15 t/day held 4 days, 5.5 m room, 32 °C ambient.
Result: ≈ 57.8 kW chilling duty (≈ 16.4 TR · 197,000 BTU/h).
Mid-size supermarket on a transcritical CO₂ pack with doored chilled cabinets.
Result: ≈ 44.5 kW pack (≈ 12.7 TR · 152,000 BTU/h) and ≈ 210 MWh of refrigeration electricity per year.
Annual kWh and operating cost from duty, efficiency and tariff.
A 5,000 m³ frozen store has 120 kW duty, COP 2.6, 8,000 h/year and 0.55 average load.
Result: About USD 28,024 per year before taxes.
One +2/+8 °C pharmaceutical room with 60 kW refrigeration duty at COP 2.8.
Result: USD 21,600 per year, USD 216,000 over ten years before escalation.
4,000 m³ frozen store in a warm climate with daily dispatch and a standard modern plant.
Result: ≈ 1.9 GWh per year of refrigeration electricity (≈ 216 kW ≈ 61 TR average) before maintenance, monitoring and labour.
Payback, total cost of ownership and like-for-like quote comparison.
A retrofit requires USD 605,000 installed and produces USD 145,000 annual net benefit over ten years.
Result: 4.2-year simple payback; read NPV and IRR on the live tool.
Retrofit of a plant using 600,000 kWh/yr with a 22% improvement (the page's default inputs).
Result: Simple payback ≈ 8.7 years; a grant or a higher improvement shortens it directly.
Supplier A: 180 kW, COP 2.6, USD 420,000 CAPEX, USD 14,000/year maintenance, two downtime days.
Result: 10-year TCO about USD 1.187 million for Supplier A.
Supplier B quotes USD 780,000 for 420 kW but excludes civil, insulation and electrical scope.
Result: Partial scope exposed and restated — the tool does not rank or recommend bidders.
Illustrative financing of a USD 2,000,000 project with 15% down over seven years at 7.5%.
Result: About USD 2,490,306 total paid. ColdMatch does not lend; qualified projects may be introduced to independent financing partners.
Rank likely causes before sizing replacement capacity.
A freezer room does not reach −20 °C; 30 °C ambient, frequent door opening, heavily iced evaporator.
Result: Infiltration first (High), defrost second (High), condenser third (Medium) — inspection priorities, not a diagnosis.
Illustrative planning examples only, not an engineering design or a quotation. Final duty, equipment and cost require a verified heat-load calculation and supplier quotations. ColdMatch Group is a supplier-neutral procurement platform — the project team reviews each request before any supplier introduction. See also the facility sizing guide and the full tools directory.
