This paper sets up the heat-condition differential equations of cylindrical envelope by Laplace transformation and introduces the transfer function method into calculating the cooling load of air conditioning in submarine. As a result, a mathematical model is built up to calculate the thermodynamic system of cylindrical envelope. Based on the transfer function model, the cooling load of air conditioning in submarine can be calculated more accurately than by conventional calculating method. It is proved that the transfer function method is suitable for this calculation.
