冷库耗电量与电费计算器：估算年度成本
本计算器根据制冷设备负荷（kW）、年运行小时数与当地电价，测算冷库全年电费支出（美元），并区分电量费用与需量/容量附加费两部分。

冷库年电费 = 平均电力负荷 × 运行小时数 × 电价，再加上需量（kVA）附加费。制冷设备通常占冷库总电费的60–70%，一座运营良好的设施冷藏库年耗电约30–60 kWh/m³，冷冻库约55–100 kWh/m³。
年度电费 = kW × 年运行小时数 × 负荷系数 × 电价（美元/kWh）+ 峰值kW × 需量费率 × 12

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
冷库耗电量和电费怎么计算？
先用制冷负荷除以系统COP估算输入功率，再乘以年运行小时数和负荷系数得到年耗电量；电费还应加入当地电价及需量费用。
智能控制能节省多少电费？
采用EC变频风机、浮动冷凝压力控制与自适应化霜策略，通常可降低15–25%的耗电量。
需量电费一般会增加多少成本？
按kVA/kW计费的需量电费，通常会在纯电量费用基础上再增加20–35%的总电费支出。
制冷设备在冷库总电费中通常占多大比例？
制冷系统通常占冷库总电费的60–70%，一座运营良好的冷藏库年耗电量约为30–60 kWh/m³，冷冻库则约为55–100 kWh/m³。
如何把电费估算结果用于设备选型或谈判？
记录年耗电量（kWh）与年度电费（美元）估算值，连同制冷负荷kW和运行小时数一并提交给ColdMatch整理为项目简介。ColdMatch会先人工审核，再决定是否引荐匹配的独立供应商，不作任何电价或节能效果的承诺。
