A simple mathematical method will be proposed to estimate the cooling tower performance at off-design ambient conditions. The cooling tower data will be used as a starting point and the CTI toolkit will be used to calculate psychrometric properties and the Merkel number at off-design conditions to calculate the temperature of the cold water leaving the cooling tower using the slop of the cooling tower characteristic curve. By applying first principles and straightforward relationships for condensers, the condenser performance at off-design conditions can be predicted.
