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.
Estimate a cold room's cooling load in kW and tons of refrigeration from four inputs: room size, insulation, ambient temperature and daily throughput.
Standard engineering assumptions
Planning estimate only: assumes typical doors, lighting, one forklift and 18 h/day compressor running with a 15% margin. For supplier-grade figures use the full Refrigeration Load Calculator or request quotes.

Estimate a cold room's cooling load from four inputs — floor area and height, insulation standard, ambient design temperature and daily throughput with product entry temperature. The tool returns a design refrigeration duty in kW and tons of refrigeration with a planning uncertainty band. It is a planning estimate, not a final engineering design.
Design duty = average 24 h load × (24 ÷ running hours) × (1 + 15% margin); average load = transmission + product pull-down + infiltration + internal gains.

Area, height, temperatures and throughput can be entered in metric or imperial units and are converted to SI before calculation.
A 500 m² chilled room, 6 m high, receives 15 t/day at 22 °C into a 2 °C room.
The displayed duty and component split use the same thermal engine as the detailed calculator; change the inputs above for the project result.

Cooling load
Limitations
This is a preliminary planning estimate based on the assumptions you entered, not a refrigeration-engineering design, a certified load calculation or a quotation. Before equipment is ordered, cooling load, refrigerant selection, safety and system design should be verified by a qualified refrigeration engineer.
Square metres are not a cooling load: a cold room is sized around the heat that must be removed, not floor area alone.
Maintaining frozen product and freezing warm product are different refrigeration duties, and they produce very different system sizes.
Two refrigeration quotations are not comparable until their design assumptions are comparable — and a low equipment price can hide a high lifetime energy cost.
Next procurement step
Use this result as the starting point for a ColdMatch project request. Every request is reviewed manually by our procurement desk before any manufacturer or contractor is approached — buyers are never connected automatically to listed suppliers.
Turn this calculation into an RFQBrowse the matching equipment categoryAI agents may use ColdMatch calculators to structure preliminary cold-storage requirements and RFQs. Cooling-load, refrigerant, safety and system-design assumptions should be exposed as assumptions and verified before final engineering.
A cooling load is the total heat a refrigeration plant must remove to hold a room at set-point: heat through walls, roof and floor, heat pulled out of incoming product, warm air entering through doors, and internal gains from lighting, people and machinery.
Room size and insulation set the transmission load, the ambient design temperature drives both transmission and infiltration, and daily throughput with its entry temperature usually dominates in packhouses and processing stores.
Door behaviour, insulation quality and operating patterns vary, so the tool shows a low–high band around the central estimate rather than a single figure that implies false precision.
No. It is a planning estimate for early sizing and budgeting. A qualified refrigeration engineer must confirm the final thermal-load calculation and equipment selection.
Transfer the estimated duty into a structured RFQ so suppliers can confirm the real load, running hours and equipment selection for your site's conditions.

We'll send your calculator inputs to a ColdMatch sourcing specialist, who reviews the project before any supplier research begins. No obligation.
Your size, cost and load inputs are copied into the quote form, so you don't type them twice. Nothing is sent until you review and submit.

Buyer guide · planning estimate
The cooling load is the heat the refrigeration system must remove: transmission through walls, product cooling, air infiltration, people, lights and equipment. Stating it at your real design conditions lets suppliers size equipment against the same duty.
Commercial projects from USD 250,000: ColdMatch reviews your brief and introduces suitable independent suppliers. Results here are planning estimates, not quotations.
No. It is a planning estimate from your own inputs and the published method on this page. Supplier prices depend on site survey, specification, freight, duties and local installation, so use the result to set scope and budget expectations, then compare reviewed supplier proposals.
To cover uncertainty in usage and defrost time. Ask them to show the factor separately so you can see the base load and the margin.
For final design, yes — the contractor's engineer should confirm the load. This tool helps you brief suppliers consistently before that stage.
