This report covers the activities of utilisation project “Energy efficient swimming pools – engagement and utilization”. This involved project partners: School of PV and RE Engineering, UNSW, Simply Better Pool Savings, and Randwick Council.
A whole system approach was adopted to optimize a residential pool filtering system. This project presents for the first time, the experimental measurements of the pool water quality (i.e., the chemical concentrations) and all energy-consuming components when operating the filtering system at low flow conditions.
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.
