Latent effectiveness of deiccant wheel : a silica gels- water system

Abstract EN

A latent heat effectiveness model in term of dimensionless groups ? = f (NTU, m*, Crm*) for energy wheel has been analytically derived.

The energy wheel is divided into humidification and dehumidification sections.

For each section macroscopic mass differential equations for gas and the matrix were applied.

In this process local latent effectiveness (? c ,? h) for the humidification and dehumidification sections of the wheel were obtained.

The latent effectiveness of the wheel is then derived from local effectiveness [? = f (? c,?)].

The model is compared with the existing experimental investigation and manufacturer data for energy wheel.

More than 90 % of the experimental data within a confidence limit of 95 %.
