Information

The cooler is thought to be a dry-air cooling device. The outlet temperature of the CO2 is imposed as max(T_low_cycle,T_amb+3). The variation of the ambiant temperature is taken into account in the estimation of the electricity demand for the fans, such as: P_cooling*deltaT/Q_cooler is a constant, deltaT being the average of the temperature of the CO2 and the ambiant, and Q_cooler the energy to withdraw.
