制冷量计算器：kW、BTU/h与冷吨换算
本工具帮助您快速估算冷库或速冻库所需的制冷量，结果以kW、BTU/小时和制冷吨三种单位同步显示，便于比较不同供应商的方案。

制冷量计算器把房间总热负荷换算为kW、BTU/小时与制冷吨：1 kW = 3,412 BTU/小时 = 0.284 TR。参考负荷密度：冷藏库（0至+4°C）约40–60 W/m³，冷冻库（−18至−25°C）约60–90 W/m³，速冻库约150–400 W/m³，之后再加10–20%安全系数。
制冷量（kW）= 容积（m³）× 负荷系数（W/m³）÷ 1000 × 安全系数 · BTU/小时 = kW × 3412 · TR = kW ÷ 3.517

- 1输入房间容积（m³），或长×宽×高。
- 2选择温度等级和保温标准。
- 3补充产品降温负荷和门开频率强度。
- 4对比kW/BTU/TR三项结果，并使用情景选择器估算不同供应商报价的合理区间。
What this calculator estimates — and what can change it
- Calculated heat load (kW)
- Target room temperature
- Operating schedule (hours/day)
- Redundancy / standby capacity

- Refrigeration technology (NH₃, CO₂, HFC/HFO)
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 RFQResearch matching suppliers by refrigerant, capacity and countryAI 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.
常见问题
kW、BTU/小时和制冷吨之间如何换算？
1制冷吨（TR）= 3.517 kW = 12,000 BTU/小时。本工具会同时给出三种单位的结果，方便直接比较。
安全系数一般取多少？
常规取15–20%作为设计余量；医药GDP冷库通常还需额外配置N+1备用制冷能力。
环境温度会影响计算结果吗？
会有明显影响。相比温带气候，炎热或热带高湿环境可能使设计负荷增加20–30%。
计算器里的温度等级分类依据是什么？
分为冷藏（+2至+8°C）、冷冻（−18至−25°C）、速冻（−35至−40°C）与医药GDP（+2至+8°C）四类，每类对应不同的W/m³参考负荷密度，用于估算基础制冷量。
如何将结果用于制冷设备询价？
记录kW、BTU/小时和TR三项结果，连同房间容积、温度等级与气候条件一并整理成询价简介。ColdMatch会先人工审核该简介，再决定是否引荐匹配的独立供应商，不会替供应商作任何价格或性能承诺。
