Cross-flow heat exchangers are important components in many industrial processes including air conditioning and power generation. A transient model of a cross-flow heat exchanger used for cooling moist air was developed by considering three control volumes. The conservation laws were applied to produce a system of simultaneous equations, which was solved numerically using an explicit finite-difference method. The computer model simulates the transient response of the heat exchanger to disturbances in fluid temperatures and flow rates. The model evaluates the psychrometric properties of moist air and the possibility of cooling the air below its dewpoint temperature. Examples are presented along with results using standard dimensionless parameters.
