Experimental and numeriacal study of moisture movement inside an air conditioned space

Abstract EN

This research is concerned with a computational study to simulate a turbulent three dimensional buoyancy recirculation flow in an air-conditioned space.

The study includes the simulation of heat and moisture generated from an internal source inside the space.

An experimental facility to study temperature and moisture distribution in an air-conditioned space has also been designed, constructed and tested in a laboratory scale.

A numerical procedure was carried out to solve the elliptic partial differential equations that govern the flow, heat and mass transfer in a finite–volume form.

The finite–volume approach was applied to solve these equations using the upwind–differencing scheme.

The SIMPLE iterative procedure [1] for solving the algebraic equations is employed in the present study.

The proposed method is the line by line technique uses the Tri-Diagonal Matrix Algorithm (TDMA) as its basic unit.

A modified version of a three-dimensional elliptic computer code was used to simulate heat and moisture transfer generated from the internal source inside the space.

A study of the flow, heat and mass transfer in air-conditioned space are used as test cases to justify the performance of the computational procedure.

The temperature and moisture distribution were compared with predictions of previous researchers.

The data from the experimental model was also used to verify the computational procedure predictions.
