-----Energy-saving swimming pool renovation plan | University swimming pool water quality improvement | Swimming pool constant temperature system design
Sichuan University of Finance and Economics is a well-known financial and economic university in the southwest region. The swimming pool on campus has long faced problems such as aging equipment, substandard water quality, and high energy consumption. In order to meet the growing fitness and teaching needs of teachers and students, the school launched a swimming pool equipment upgrade project. By introducing AQUA swimming pool equipment and ESPA filter system, a smart swimming pool space that meets international standards was created.
1. Upgrade of swimming pool circulation filtration system
(1) Equipment upgrade
ESPA horizontal filter sand cylinder: adopts multi-directional valve control technology, the filtration area is increased by 40%, and it is equipped with high-precision quartz sand filter material (filtration accuracy up to 5 microns), which can intercept suspended matter such as hair and dandruff.
AQUA AK series swimming pool pump: equipped with variable frequency motor, the flow range is expanded to 30-200m³/h, supports intelligent adjustment of water circulation speed, and reduces energy consumption by 25%.
(2) Technological breakthroughs
Dual circulation mode: Daily low-flow circulation (energy-saving mode) and peak high-flow circulation (cleaning mode) automatically switch to ensure water quality uniformity of more than 98%.
(3) Achievements:
Suspended solids removal rate: increased from 78% before the transformation to 99.2%, and pool water transparency reached NTU≤0.5 (national standard ≤1).
Energy consumption comparison: Daily average operating power consumption dropped from 120kW·h to 85kW·h, saving more than 30,000 yuan in electricity bills annually.
2. Disinfection and purification system upgrade
(1) Optimization content:
Ozone disinfection technology
AQUA ozone generator: adopts high-frequency discharge technology, ozone production reaches 10g/h, and sterilization efficiency reaches 99.99% (for Escherichia coli, Staphylococcus aureus, etc.).
ESPA ozone booster pump: pressure increased to 0.8MPa, ozone dissolution efficiency increased by 50%, and with activated carbon adsorption cylinder, residual chlorine residue is eliminated (residual amount ≤0.1mg/L).
(2) Intelligent management
PH/ORP online monitoring: real-time adjustment of water quality parameters (PH value is stable at 7.2-7.6), total colony count is controlled at ≤80CFU/mL (far lower than the national standard of 200CFU/mL).
(3) Achievements:
Disinfection efficiency: bacterial inactivation time is shortened from 30 minutes to 8 minutes, and odor elimination rate is 100%.
Operation and maintenance cost: chemical agent usage is reduced by 60%, and annual maintenance cost is reduced by 28,000 yuan.
3. Constant temperature system upgrade
(1) Optimization content:
Air source heat pump technology
AQUA constant temperature heat pump: COP value (energy efficiency ratio) reaches 4.8, and can still heat stably in a low temperature environment of -15℃, and water temperature fluctuation is controlled within ±0.5℃.
Intelligent temperature control module: supports APP remote control, pool water temperature difference ≤1℃ (national standard ≤2℃).
(2) Safety design
Water-electricity separation structure: through IPX8 waterproof certification and antifreeze protection technology, the failure rate is reduced by 90%.
(3) Achievements:
Constant temperature performance: The pool water temperature is constant at 26-28℃ in winter, and the heating speed is increased by 40% (5℃ rise in 4 hours).
Energy-saving benefits: Compared with traditional electric heating, it saves 120,000 kW·h of electricity per year and reduces carbon emissions by 32 tons.
4. Comprehensive transformation results
(1). Data-based benefit comparison
Indicators | Before transformation | After transformation | Increase |
Daily average power consumption | 580kW·h | 380kW·h | ↓34.5% |
Water quality compliance rate | 72% | 99.6% | ↑38.3% |
User satisfaction rate | 68% | 94% | ↑38.2% |
Equipment failure rate | 8 times/year | 1 time/year | ↓87.5% |
(2). User feedback and social value
Teacher and student experience: 90% of users agree that "the water quality is clear and odorless", and the attendance rate of swimming courses has increased by 25%.
Teaching support: The Sports Department reported that "the stability of water temperature ensures 100% execution of the teaching plan".
Industry benchmark: The project was rated as "2023 National College Green Swimming Pool Demonstration Project", attracting more than 10 colleges and universities to inspect and study.
