Hangzhou Water Park needs to build an open-air and indoor dual swimming pool system to meet the core needs of year-round operation, energy saving and high efficiency, and safety control, while taking into account the daily leisure of owners and the experience of tourists in scenic spots, and promoting the development of "leisure + tourism" dual scenes.
Solutions and technical highlights
1. Intelligent water circulation system
High-efficiency filtration: Quartz sand filtration (precision 20-50μm) combined with hair collectors to achieve three cycles of pool water per day, turbidity stability <1NTU (reaching the national standard GB 37488-2019).
Energy-saving frequency conversion: The water pump automatically adjusts the flow rate according to the passenger flow, and the comprehensive energy consumption is reduced by 30%.
2. Dual-source constant temperature system
Main heat source: air source heat pump (energy efficiency ratio ≥3.5), the water temperature is constant at 26-28℃ in winter, which adapts to the wet and cold climate of Hangzhou.
Auxiliary energy: Solar collectors account for more than 50% of summer heating, reducing dependence on traditional energy.
3. Unmanned water quality management
Online detectors monitor residual chlorine (0.3-0.5mg/L) and pH value (7.2-7.6) in real time, and link automatic dosing, with zero water quality complaints in the first year.
4. Full-scenario safety design
Anti-slip protection: countercurrent overflow grille reduces the risk of slipping and buffers the impact of water waves.
Intelligent monitoring: underwater explosion-proof LED lights (4000K color temperature) + life-saving observation platform, achieving 24-hour safety coverage without dead ends.
Implementation effect
1. 100% water quality meets standards and zero complaints
Strictly in compliance with GB 37488-2019 hygiene standards, zero water quality complaints were achieved in the first year of operation (turbidity <0.5NTU, 40% better than the national standard).
2. Energy consumption costs dropped by 25%
The comprehensive energy consumption was reduced by 25% compared with the traditional solution, saving 40,000 yuan per month (winter operating costs from 160,000 to 120,000/month), and annual electricity bills saved more than 480,000 yuan.
3. Operation and maintenance efficiency doubled
The intelligent management system reduces manual inspections by 50%, responds to faults in 2 hours (6 hours in traditional mode), and the equipment online rate is >99%.
Project highlights
Four-season operation: air source heat pump + solar energy combination solves the problem of temperature difference between winter and summer and achieves high efficiency and energy saving.
Intelligent control: automatic water quality management + frequency conversion system, reduces manpower dependence and improves stability.
Safety experience: from anti-slip design to all-weather monitoring, build a "zero hidden danger" swimming pool environment.
Customer evaluation
"This system not only solves the problem of high operating costs in winter, but also the intelligent management method greatly reduces the workload of the operation and maintenance team. Tourists' satisfaction with water quality and constant temperature experience has significantly improved, becoming a new selling point for the scenic spot."
