The distribution of chilled water flow rate in terminal unit is a major factor used to evaluate the performance of central air conditioning unit. In this work, a theoretical chilled water distribution in the terminal units has been studied to predict the optimum heat performance of terminal unit. The central Air-conditioning unit model consists of cooling/ heating coil (three units), chilled water source (chiller), three-way and two-way valve with bypass, piping network, and pump. The term of optimization in terminal unit ingredient has two categories, the first is the uniform of the water flow rate representing in statically permanents standard deviation (minimum value) and the second category is the maximum heat transfer rate from all terminal units. The hydraulic and energy equations governing the performance of unit solved with the aid of FORTRAN code with considering the following parameters: total water flow rate, chilled water supply temperature, and variable valve opening. It was found that the optimum solution of three-way valve case at 8°C water supply temperature, 0.12 kg/s total water flow rate and valve opening order (valve 1: 100%, valve 2: 100% and valve 3: 75%) with total heat rate (987.92 Watt) and standard deviation (1.181E-3). Also, for the two-way valve case the results showed that the optimum condition at 8°C water supply temperature, 0.12 kg/s total water flow rate and valve opening order (valve 1: 75%, valve 2: 75% and valve 3: 50%) with total heat rate and standard deviation (717Watt) and (5.69E-4) respectively.

It leads to the use of circumstances that through which the individual can achieve the accomplishments and gains. Once initiation spreads in the community, it will become a vivacious and that will lead to the development of its reality into the best. The Messenger (PBUH)( has encouraged imitation and the companionsshowed many imitations to deal with the economic issues that are vital to the stability of the peoples and communities and to achieve the necessary level of income and livelihood pursuant to what the Islamic economy has stipulated. Therefore, finding the ideal means to employ what Allah Almighty has endowed to humanity.
Nesrin Erbil, Çağdaş Türk şiirinin kıvançla söyliyebileceğimiz öncü bir isimdir. Gerçek aşk, ayrılık, üzüntü, sevgiliye hasretin yetiştirdiği ve olanaksızlıklara haykıran bir sesidir. O bir Türkcesine tüm zencirleri kıran engelleri aşan sevgiyle sevgiye ve sevgiliye koşan kendi başına bir yaratıcılıktır. Şiirleri Erbil kokar yumuşak saçının tellerini Altın Köprü suyuyla yıkamayı diler. Yüreği ise Gürgür Baba’dır Türkmen için yanar.
