Résumé

The central chilled water system servicing one of the academic buildings at the KFUPM campus located in Dhahran has been modeled numerically to combine with the ejector cooling system. This ejector system cools the water which is in turn utilized to cool the refrigerant in the chiller condenser and hence, the function of the cooling tower in a conventional chilled water system is eliminated by an ejector cooling system. By replacing the cooling tower of the chilled water system with an ejector cooling system, constant water inlet temperature for the chiller condenser is assured, regardless of the ambient relative humidity and this effect is analyzed in detail. Results indicate that this combined system is quite advantageous at conditions of high ambient relative humidity when the cooling capacity of the cooling tower is greatly diminished but the performance of the ejector cooling system remains unaffected.
