The impact of low-speed filtration on the performance of salt water chlorinators, pool cleaners, and the pool water quality, based on experimental and modelled data, is investigated. Results show that a typical salt water chlorinator and pressure pool cleaner do not work well for flow rates of less than 1 litre s -1 and 1.3 litre s -1 respectively.

Highlights

• Validated swimming pool and collector model, good agreement with experimental data.
• Solar pool heating system performance optimized based on COP (energy ratio).
• Optimized system achieves pump energy savings of approximately 60%.
• System produces enough pressure to keep the vacuum relief valve closed.
• Potential for 180 GWh of electricity & 150 kt of CO2 savings per year in Australia.
