Evaporative cooling has been considered for sustainable and efficient air-conditioning since ancient times. Nowadays, improved concepts have led to a large variety of applications from direct conditioning of indoor and outdoor environments up to sensible air-cooling through different configurations of Indirect Evaporative Cooling (IEC) schemes. However, better understanding and mathematical modelling of the process is still needed for design and operational optimization of such systems. This work addresses a MATLAB implementation of an off-design model for a crossflow IEC unit based on previous literature work. Then, multiple parametric runs are conducted to identify the influence of critical process characteristics and modelling aspects such as heat and mass transfer coefficients and surface wettability. Results provide insight to further modelling and simulation research, also extending the approach to other system designs and flow configurations.
