“CSIRO has invented a new three in one solar air conditioning system that provides hot water, cooling and heating.
It works by using heat from the sun and employs both desiccant and evaporative cooling technologies. See how the technology can work in the home.”
I don’t see that this is an indirect evaporative cooler. Maybe their diagram is incorrect but I see air coming in, passing through a desiccant wheel and then continuing on to the house. If it were a true “Indirect” system, there would be no need for the desiccant. The cool/moist air would pass through a heat exchanger and then return to the outside. Thus they are called “Indirect”.
