Model for an indirect wet evaporative cooler. In this component, the primary airflow
186+
is cooled within the heat exchanger by an evaporative effect when water is directly
187+
sprayed on to the secondary surface of the heat exchanger to saturate the secondary
188+
air-flow. Therefore, it is assumed that the secondary air is completely saturated,
189+
