Copyright © 2014 by ASME. A Computational Fluid Dynamics (CFD) software package is used to investigate numerically a 3-dimensional rectangularbox room installed with heat pipes heat exchanger (HPHE). Heat pipe heat exchanger utilizing refrigerant by mean of working fluid is installed on top of a room. The air-side heat transfer and the flow pattern of a thermo-siphon heat pipes is studied with a natural driven ventilation of a building. Different opening of the inlet and outlet air where the heat pipe was installed are tested with round edges opening as well as sharp edges. The standard RANS κ-ε turbulence model is used. Results with different setting of heat pipe and opening characteristic, air flow rate and flow pattern as well as its temperature effects are examined.
