Phase 1: Basic Upgrade (0 production stoppages):
Nighttime installation of centrifugal booster and air tank → ensuring stable air pressure the next day Weekend deployment of oil cooler cycle 1 (spindle cooling)
Phase 2: Core Modification (≤ 2 days of production stoppage):
1. Cutting Area: Oil Cooler Circulation 2 (Cutting Fluid Cooling) + Double-Wall Piping 2. Entire Workshop: Waste Heat Recovery Piping Installation 3. Rest Area: Absorption Chiller Installation

Dual-Loop Oil Chiller:
Cycle 1 (spindle cooling): Maintains a constant temperature of 20°C ± 0.5°C, minimizing thermal deformation (measured deformation ↓ 61%).
Cycle 2 (cutting fluid cooling): Maintains a constant temperature of 25°C ± 0.3°C, ensuring a surface roughness Ra ≤ 0.4μm.
Energy-saving design: R513A refrigerant (GWP = 573) + plate heat recovery, saving $18,000 in annual electricity.
Centrifugal Air Booster:
Technical Principle: VFD-driven booster compensates for air pressure fluctuations (0-10 bar instantaneous response).
Performance Advantages:
Pneumatic tool pressure fluctuation ≤±0.8% (±3.5% before retrofit).
When used with a 2,000L air tank, pressure recovery speed increases by 50%.

Waste Heat-Driven Absorption Chiller:
Heat Source: Waste heat from the air compressor and spindle motor (>80°C) drives a lithium bromide chiller.
Output: Provides 120 kW of free cooling in the summer for the rest area (covering a 40-person workshop).
Economic Benefit: Replaces traditional air conditioning, saving $12,000 in gas costs annually. AI-Powered Load Forecasting:
Control Logic:
Based on order volume, material hardness, ambient temperature and humidity, pre-cooling equipment is used.
During peak hours, centrifugal compressors are activated to prioritize the precision machining area.
Data Verification: Air compressor inoperative time decreased by 90%.
