Like many people living in Darwin, Michael Bruvel was disappointed that his new pool was as warm as a bath and provided no relief from the heat and humidity. So he decided to do something about it. Michael has developed a clever water-cooling system called Aquasense. It can be used on everything from a backyard swimming pool to an aquaculture pond or a swimming lagoon. Aquasense provides a web-based interface that allows algorithms to fine tune heat transfer and evaporative cooling processes in response to atmospheric conditions. This allows for efficient cooling and automated temperature control of the pool during hot and humid weather. It is triggered when poolside sensors - measuring humidity and ambient temperature, and using weather forecast data - assess that conditions are suitable for cooling and the water is above a chosen temperature. The system even determines when is the most efficient and economic time to go into action. The most obvious cause of soaring water temperatures in the tropics is the prolonged hot periods. If day after day the temperature isn't getting below 28, eventually your pool will get unpleasantly warm. Some pools I have monitored are 3 but it is common for pools in Darwin to be around 31 to 33, which is not refreshing. Using the Aquasense system, I maintain my pool at around 27 to 28, which is refreshing yet still warm enough to relax in.
