生命周期成本计算器(LCC)
计算总拥有成本,包括购置、能源、维护、停机和处置——所有成本均按设备整个使用寿命的现值折现。
成果
生命周期成本公式
总生命周期成本(LCC)包括设备在其使用寿命内的所有成本,并折现至现值:
其中 C年度的 = 能源 + 维护 + 停机时间,按 n 年计算,折现率为 r。
年度成本净现值(年金因子)
当年度成本保持不变时,净现值 (NPV) 是使用年金现值系数计算的:
年度等效成本
年度等效成本(AEC)将总生命周期成本平均分摊到设备的整个使用寿命期间:
典型成本细分
| 设备 | 购置 | 能源 | 维护 | 其他 |
|---|---|---|---|---|
| 工业泵 | 5-15% | 70-85% | 5-15% | 1-5% |
| 电动机 | 1-5% | 90-97% | 1-3% | <1% |
| 压缩机 | 10-20% | 60-75% | 10-15% | 2-5% |
| 暖通空调系统 | 15-25% | 50-65% | 10-20% | 5-10% |
实例
已知: 购置成本 = 5,000 欧元,安装成本 = 1,000 欧元,能源成本 = 500 欧元/年,维护成本 = 300 欧元/年,使用寿命 = 15 年,折现率 = 5%
C年度的 = 500 + 300 = 800 欧元/年
年金因子 = (1 – (1.05)-15) / 0.05 = 10.3797
运营净现值 = 800 × 10.3797 = €8,304
LCC = 5,000 + 1,000 + 8,304 = €14,304
收购份额 = 6,000 / 14,304 = 42%
年化当量 = 14,304 / 10.3797 = 每年1378欧元
💡提示: 对于水泵和电机而言,能源成本通常是生命周期成本的主要组成部分。投资购买效率更高、购置成本更高的设备通常可以显著降低总生命周期成本。
Lifecycle Cost (LCC) is the total cost of owning and operating an asset over its entire useful life. It includes acquisition, installation, energy consumption, maintenance, downtime losses, and end-of-life disposal costs — all discounted to present value.
LCC analysis helps make better purchasing decisions by looking beyond the initial price tag.
The discount rate reflects the time value of money — a euro today is worth more than a euro in the future. It accounts for inflation, investment opportunity cost, and risk.
- Higher discount rate — future costs weigh less, favoring low-operating-cost options less
- Lower discount rate — future costs weigh more, making energy-efficient equipment more attractive
- Typical range: 3–8% for industrial equipment
Purchase price is only the upfront acquisition cost. LCC includes all costs over the equipment's entire life:
- Acquisition and installation
- Energy consumption (often the largest component)
- Maintenance and repairs
- Downtime and production losses
- Decommissioning and disposal
For pumps, the purchase price is typically only 5–15% of the total LCC.
The split varies by equipment type:
- Industrial pumps: 5–15% acquisition, 85–95% operating
- Electric motors: 1–5% acquisition, 95–99% operating
- Compressors: 10–20% acquisition, 80–90% operating
- HVAC systems: 15–25% acquisition, 75–85% operating
Energy costs dominate for most rotating equipment.
Key components:
- Energy: Power (kW) × Annual hours × Price (€/kWh). For a 5 kW pump running 8,000 hr/yr at €0.12/kWh → €4,800/yr
- Maintenance: 2–6% of acquisition cost per year, or use historical records
- Downtime: Expected failures/yr × Hours per repair × Production loss per hour
