VIII. Energy Saving & Cost Reduction
APEX's electrical control cabinets and motor systems achieve comprehensive electricity savings of 5%-60% through integrated technologies like variable frequency speed regulation, intelligent control, and efficient hardware design. The core energy-saving mechanisms are as follows:
I. Variable Frequency Speed Regulation: Dynamically matches load demand (Energy saving contribution: 10%-35%)
1. Precise Motor Speed Adjustment
• Uses inverter + PLC control cabinet combination to adjust motor speed in real-time based on actual load demand (e.g., pump, fan loads), avoiding energy waste from traditional fixed-speed 'big horse pulling small cart' operation.
• Measured data: In sewage plant lift pump applications, VFD speed control reduced energy consumption by 20%-70%; central air conditioning chilled water systems achieved 15%-30% energy savings through variable flow control.
2. Soft Start Function
• Achieves smooth motor start via inverter, eliminating inrush current during traditional starts (peak can be 5-7 times rated current), reducing equipment wear and extending motor life.
II. Intelligent Control System: Multi-dimensional energy efficiency optimization (Energy saving contribution: 5%-15%)
1. Adaptive Adjustment Strategy
Integrated PLC + touch screen control cabinet automatically adjusts equipment operation mode based on environmental parameters (temperature, pressure, flow). For example:
Air conditioning systems dynamically distribute cooling/heating, preventing zone overcooling or overheating;
Industrial equipment starts/stops on demand, reducing无效 running time.
2. Energy Consumption Monitoring & Warning
• Real-time collection of voltage, current, temperature data, using algorithms to identify abnormal energy consumption (e.g., cooling fan idling), triggering alarms or automatic shutdown.
III. Efficient Hardware Design: Reduces basic losses (Energy saving contribution: 3%-10%)
1. Low-Loss Motor Selection
• Uses IE4 high-efficiency permanent magnet synchronous motors, improving efficiency by 3%-5% compared to traditional asynchronous motors, reducing iron loss by 20%.
• Optimizes motor heat dissipation structure (e.g., forced air cooling + thermal conductive materials), reducing efficiency decay caused by temperature rise.
2. Control Cabinet Energy Saving Modification
• Segmented Resistor Design: Distributes centralized resistors into modular units, reducing无效 power loss;
• Natural Heat Dissipation Optimization: Increases cabinet ventilation area,配合 intelligent fan start/stop strategy,降低散热能耗.
• After modification: Using VFD control cabinet + high-efficiency motor, annual power consumption reduced to 780,000 kWh, electricity cost 468,000 CNY;
• Payback Period: Equipment investment approx. 500,000 CNY, annual electricity saving收益 252,000 CNY, payback period 1.98 years.
