3.2 The dehumidifying coil and preheating coil calculation

The calculation of dehumidifying and preheating coils has been studied and is shown in [11, 12]. However, a clear and detailed procedure for simulating the performance of dehumidifying coils was not available in these references. Hence, a numerical model of the performance of the dehumidifying and the preheater coils in this research was developed from the handbook and the standard. The calculation procedures for the psychometric properties of humid air were given in [11]. A detailed procedure for simulating the coils of preheating and dehumidifying of an active distillation system is presented in [9].

The simulation of the preheater includes (i) computing the heat transfer coefficient for the coil, (ii) computing the coil effectiveness, and then (iii) calculating the air and cooling water temperatures leaving the coil.

The simulation of the dehumidifying includes finding consistent values of temperature and humidity by using an iterative process.
