The weather in Kuwait is very dry where thedry-bulb temperature exceeds the wet-bulbtemperature more than 20oC in most of the summermonths. Thus, the air-conditioning (A/C) system withthe water-cooled (WC) condensers is expected toperform more efficiently than with the air-cooled(AC) condensers. This fact was behind the idea of afield study conducted in one of the major hospital inKuwait during a summer season to investigate theperformance of WC and AC systems in terms of peakpower and energy consumptions. The coolingcapacities for WC and AC systems were 373 and 278tons-of- refrigeration, respectively. It was found thatfor the same cooling production, the peak powerdemand and the daily energy consumption of the WCsystem were 45 and 32% less than that of the ACsystem, respectively. The maximum reduction in thepower demand coincided with the peak powerdemand period of the utilities i.e. between 14:00 and17:00 hr, thereby offering a maximum advantage ofpeak power saving.
