Energy evaluations between air-cooled vs. water-cooled cooling systems in non-residential buildings.

Author(s) : MEDHAT FAHIM A. A., KHALIL E. E.

Summary

This study is devoted to specifying the optimization of use of air-cooled vs. water-cooled cooling systems based on the climatic region classification. It proposes affecting design criteria's, which could be implemented in HVAC Uniform Code for Middle East, and especially for the Egyptian HVAC and energy codes. It yields selection criteria's for typical size ranges, where a water-cooled cooling systems are more economical than air-cooled systems and vise versa. This concept has impacts on energy efficiency and conservation. Study is concerned to the field survey, and energy analysis of non-residential buildings in Egypt, covering seven main climatic regions, on which, each region shall be defined for specific cooling system configurations. One of the conclusions is that for newly designed projects, located almost in all Egyptian climatic regions, with any cooling capacities, could be designed based on water-cooled system with minimum initial and running cost taking into consideration the availability of different water sources in Egypt.
