Abstract:

 The yearly energy consumption of heating, ventilation and air conditioning HVAC system for an operating room OR, placed in four different countries such as Adana in Turkey, Astana in Kazakhstan, Mosul in Iraq and Dushanbe in Tajikistan have been performed in this study. This study aimed to economically evaluate the use of a 100 fresh air HVAC system in countries with different climate types in identical operation room. Moreover, 10 years life span has been calculated using Life Cycle Cost LCC method for the considered countries. As a result, energy consumption of system is lower in regions with a cold climate type such as Astana in Kazakhstan with 6.58 kW and Dushanbe in Tajikistan with 7.15 kW while is higher in hot climates, such as Adana in Turkey with 12.87 kW and Mosul in Iraq with 9.256 kW. The annual and hourly cooling load for Mosul in Iraq are higher, but the total cooling load and total energy consumption are 40.6 less than these of Adana in Turkey because the fact that the wet-bulb temperature of Mosul in Iraq is lower than it of Adana in Turkey. The HVAC systems energy consumption is in direct proportion to the LCC value of the system. For this reason, Astana in Kazakhstan, which has a cold climate type, has the lowest LCC value with 116324.332. In conclusion, the 100 fresh air HVAC system can be used for analyzed countries but it is more economical in cold climates and countries with low wet -bulb temperatures.
