For commercial and industrial refrigeration projects (cold rooms, cold stores, process cooling) — not household fridges, home freezers or appliance repair. Results are planning estimates, not engineering design or safety advice; a qualified refrigeration engineer must confirm sizing before purchase.
Indicative planning benchmarks, not an engineering result. Adjust inputs to your facility and verify with a qualified refrigeration engineer.

Model kWh, cost and CO₂ savings from LED lighting, EC fans, VSD compressors, night set-back and improved insulation in cold storage plants.
Refrigeration is typically 60–70% of a cold store's electricity bill. The highest-return measures are floating head pressure control (8–15% savings), EC fan retrofits on evaporators and condensers (5–12%), demand-based defrost (3–8%), and door management with air curtains or high-speed doors (5–10%). Combined retrofits commonly deliver 20–35% savings with payback in 1.5–4 years.
Control changes: floating head pressure, demand defrost and setpoint review cost little and typically save 10–20% together.
20–35% of refrigeration energy on facilities older than ten years, with typical payback of 1.5–4 years depending on electricity tariff.
Often yes, because cooling demand peaks with sunshine. Rooftop PV commonly covers 20–40% of annual consumption in high-irradiance markets.

Calculations run in SI (m, m², m³, kW, kg, °C). Imperial equivalents: 1 m² = 10.76 ft², 1 m³ = 35.31 ft³, 1 kW = 3,412 BTU/h = 0.284 TR, 1 t = 2,205 lb, °F = °C × 1.8 + 32. 1 kWh/m³ = 0.0283 kWh/ft³.
