FAQ · Multilingual
Model kWh, cost and CO₂ savings from LED lighting, EC fans, VSD compressors, night set-back and improved insulation in cold storage plants.
- How much can a retrofit save?Typical 20–35% kWh reduction, with 2–4 year payback on VSD compressors and EC fans in tropical climates.
- Does it factor in local tariff and CO₂ grid intensity?Yes — inputs include local tariff (USD/kWh) and grid emission factor (gCO₂/kWh) to produce financial and ESG outputs.
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.
Frequently asked questions
What is the cheapest way to cut cold store energy use?
Control changes: floating head pressure, demand defrost and setpoint review cost little and typically save 10–20% together.
How much can a full retrofit save?
20–35% of refrigeration energy on facilities older than ten years, with typical payback of 1.5–4 years depending on electricity tariff.
Does solar make sense for cold storage?
Often yes, because cooling demand peaks with sunshine. Rooftop PV commonly covers 20–40% of annual consumption in high-irradiance markets.
Refrigeration energy savings: buyer questions
- How much energy can a refrigeration retrofit save?
- Typical verified savings are 15–35%: floating head pressure and suction control, EC fans, variable-speed compressors, LED lighting, door and air-curtain repair, defrost optimisation and correct refrigerant charge. Savings above 40% usually mean the existing plant is badly degraded.
- What is a realistic payback on energy measures?
- Controls, defrost tuning and door repairs often pay back in under 18 months. Compressor replacement, VSD retrofits and heat recovery typically pay back in 2–5 years depending on tariff and running hours.
- Does backup power change the business case?
- Yes. Where grid supply is unstable, generator fuel can exceed the grid bill. Reducing load lowers both the electricity spend and the generator or solar capacity you need to install.
- How do I get quotes for the retrofit?
- Send the calculated baseline and target measures through ColdMatch; the same scope goes to several energy and refrigeration contractors so savings claims and prices can be compared like for like.
