冷库制冷负荷计算器:在线估算kW与冷吨
本计算器依据房间尺寸、保温等级、环境设计温度与每日吞吐量四项输入,快速估算冷库所需的制冷负荷(kW与制冷吨),属于前期规划测算,非最终工程设计。

Standard engineering assumptions
本结果仅为规划估算:假设常规门开、照明和一台叉车配置,压缩机每天运行18小时,并含15%余量。如需符合供应商标准的数据,请使用完整版制冷负荷计算器或直接索取报价。

本工具根据四项输入估算冷库制冷负荷:占地面积和净高、保温标准、环境设计温度,以及每日吞吐量和产品入库温度。计算结果给出设计制冷量(kW与制冷吨)及一个规划估算浮动区间,仅供前期规划参考,并非最终工程设计。
设计制冷量 = 24小时平均负荷 × (24 ÷ 运行小时数) × (1 + 15%余量);平均负荷 = 传导负荷 + 产品降温负荷 + 渗透负荷 + 内部得热。

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
冷库制冷负荷怎么计算?
将各分项热量求和再加10–20%安全余量:围护结构传热(U×A×ΔT)、新入库产品降温负荷、门开渗透负荷,以及照明、人员和设备等内部得热,即得所需制冷负荷(kW)。
在这个快速估算中,哪些输入影响最大?
房间尺寸和保温等级决定传导负荷,环境设计温度同时影响传导和渗透负荷,而每日吞吐量及其入库温度往往在加工型冷库中占主导地位。
为什么给出的是一个区间而不是单一数值?
门开使用习惯、保温施工质量与实际运行模式各有差异,因此工具给出一个高低区间,而不是一个看似精确、实则可能失真的单一数字。
这是最终的工程设计计算吗?
不是。这只是用于前期规划和预算的估算工具。最终的热负荷计算与设备选型必须由具备资质的制冷工程师确认。
拿到结果之后该怎么办?
将估算得到的负荷值填入结构化询价单,交由供应商结合现场实际负荷、运行小时数与设备选型进行确认。ColdMatch会先人工审核该询价简介,再决定是否引荐合适的独立供应商。
