The following rationalization suggestions for swimming-pool energy saving and consumption reduction cover equipment optimization, operation management, and maintenance:
1. Optimize Equipment Efficiency
- Upgrade to efficient equipment: Use energy-saving pumps and filters, such as variable-frequency pumps that adjust operating power to actual demand, reducing electricity consumption.
- LED lighting: Replace pool and surrounding lighting with LED lamps — energy-saving with long life.
- Heat pump or solar heating: Adopt air-source heat pumps or solar hot-water systems instead of traditional electric heating to significantly reduce heating energy use.
- Efficient thermal cover: Install automatic or manual pool covers to reduce nighttime heat loss and evaporation, saving heating and water-treatment costs.
2. Water Circulation and Filtration Optimization
- Set reasonable circulation time: Adjust pump runtime based on pool usage frequency and water quality, avoiding unnecessary long operation.
- Backwash optimization: Regularly inspect the filtration system and use smart backwash equipment to reduce water waste and heating energy use.
- Water-quality monitoring system: Install automatic water-quality monitoring and chemical dosing equipment to precisely control dosage and reduce treatment energy use.
3. Temperature and Ventilation Management
- Reasonably control water and room temperature: Keep indoor pool water at 26–28°C, with air temperature 1–2°C above water to avoid higher heating and dehumidification costs.
- Efficient dehumidification system: Use heat-recovery dehumidifiers to recover heat from exhausted humid air for heating pool water or air.
- Natural ventilation: When weather permits, use natural ventilation to reduce HVAC and dehumidifier load.
4. Smart Management
- Smart control system: Integrate pumps, heating, lighting, and ventilation into a smart control system that automatically adjusts operation to real-time demand, reducing manual intervention and energy waste.
- Data monitoring and analysis: Use an energy-monitoring system to analyze equipment efficiency and promptly identify and optimize high-consumption issues.
5. Operation and Maintenance Optimization
- Regular equipment maintenance: Regularly clean filters and inspect pumps and pipes to reduce energy increases from aging or blockage.
- Off-peak power use: Run high-consumption equipment during lower-tariff periods, such as nighttime heating or filtration.
- Staff training: Strengthen energy-saving awareness training for operators, standardize equipment operation, and avoid unnecessary waste.
6. Reduce Water Waste
- Leak detection: Regularly inspect the pool body and pipes, repair leaks, and reduce makeup-water and heating costs.
- Rainwater harvesting: For outdoor pools, collect rainwater for pool topping up or perimeter cleaning to reduce tap-water use.
- Recycled water reuse: Treat backwash or other wastewater for irrigation or flushing to reduce water waste.
7. Policy and Incentives
- Apply for energy-saving subsidies: Follow local government or industry association retrofit subsidy policies to lower equipment upgrade costs.
- Energy audit: Hire professionals for an energy audit and develop targeted energy-saving plans.
