Air Systems
Indirect-Direct evaporative cooling is a
technique where we first use water in a heat
exchanger to cool another stream of air sensibly
(without adding moisture). The air used for
cooling water is called secondary air while the
air getting cooled in the heat exchanger which
will be sent to the room is called primary air.
Secondary Air is again exhausted back into
outdoors while cooled primary air is then
further cooled through direct evaporation
(adding moisture) before sending it to space to
be cooled. Since cooling is done in 2 stages
(indirect-direct), it’s also known as 2-stage
evaporative cooling
