modelPartialStaticTwoPortCoolingTower
Base class for test models of cooling towers
Information
Partial model to test cooling tower models that are connected to a weather data reader and a simple fluid loop to which a constant amount of heat is added. The pump in the cooling tower loop is switched on and off depending on the temperature of the control volume to which the heat is added.
