初步规划结果，基于所示输入与假设。
直接答案
湿帘降温最多只能接近室外湿球温度：ΔT =（干球 − 湿球）× 湿帘效率（6 英寸约 75%）。干球 38 °C、湿球 24 °C 时实际降温约 10.5 °C，进风约 27.5 °C。
使用方法
- 输入隧道总风量与湿帘厚度。
- 填写设计干球与湿球温度。
- 将湿帘面积与用水量与供水能力核对。
Scope of this tool
What this tool can and can't do
湿帘面积、温降与水流量。 is a planning tool for budget-stage and RFQ-stage decisions. It gives defensible numbers to compare suppliers against — it is not an engineering, veterinary or financing approval.
What it can do
- Size the required line capacity in tonnes per hour from annual tonnage, shifts and realistic uptime.
- Estimate connected load and specific energy consumption (kWh per tonne) by process stage.
- Show the effect of automation level, process type (pelleting versus extrusion) and utilisation on cost per tonne.
- Give an indicative CAPEX band and payback range for budgeting.
What it can't do
- Substitute for a vendor's guaranteed capacity or energy figures — those come with the equipment contract.
- Include site-specific electrical infrastructure, transformer upgrades, grid tariffs or generator backup unless you add them.
- Model your actual formula's grinding and conditioning behaviour, which changes energy per tonne materially.
- Serve as a bankable feasibility study or a financing document.
Required inputs
- · Target annual production in tonnes
- · Operating hours: shifts per day, days per year, expected uptime %
- · Process type (mash, pelleting, extrusion) and automation level
- · Energy tariff and labour cost if you want operating cost output
Example run
- · 60,000 t/year, 2 shifts, 300 days, 85% uptime
- · Pelleting line, semi-automated
- · Energy tariff 0.11 USD/kWh
- → Required nominal capacity: about 16-17 t/h
- → Specific energy: roughly 42 kWh/t (grinding + pelleting + handling), about 4.6 USD/t at the tariff entered
- → Indicative CAPEX band and simple payback range for budget-stage comparison
哪些因素会改变结果？

- · 粉碎与混合的循环时间
- · 各配方的制粒或膨化速率
- · 班次与有效运行小时
- · 停机、维护与工艺效率

FAQ
Common questions
湿球温度真的是极限吗？
是的。蒸发降温无法低于室外湿球温度，因此潮湿沿海地区的降温幅度远小于干燥内陆。
湿帘用水量是多少？
按每平方米湿帘 3 升/分钟的循环流量计算，并预留排污以控制结垢与盐分。
