[Su]dan Sorunlarınızı Biz Çözeriz... V A R A N Briefs from lmportant Subjects Corrosion in Closed Circuit Mechanical lnstallations-Part 1.......48 Corrosion is a slow advancing react i on. Therefore, it is common that its etfects are overlooked, and only noticed when a part or whole of the system loses its functionality. This study focuses on the definition of corrosion, general formation processes, the process of corrosion in iron and steel based materials making up the structure of mechanical installations, corrosion rate and corrosion types, as well as its etfects on closed circuit mechanical installations. The Energy Efficient Renewal of the Covered Olympic Swimming Pool and Summer Swimming Area in Kranj ..................................58 Precautions to reduce the energy and water consumption of the covered Olympic swimmingpool and summer swimmingarea have been put into etfect, in conjunction with the Projeci to Finance the Precautions far the Etficient Use of Energy of the Local Administration of the City of Kranj. The lndustry Will Experience a Dynamic Period in the Coming Years .................................................................................92 We discussed the studies being carried aut by the Natura! Gas Appliances lndustrialists and Businessmen Association (DOSIDER), Turkish heating market, and the contributions that the Energy Etficiency Law will bring to the heating sector and to the correct use of energy with Dr. Celalettin Gelik, the Executive Board Chairman of DOSIDER. Mashattan Mechanical lnstallation Systems ................................96 The heating, cooling, domestic cold and hat water systems of each block, as well as the block-based automation thereof, have been designed centrally within the concept of the Mashattan mechanical works projeci. The Etfects of Antifreeze Use on the Performance of Submersible Motors ..........................................................................................122 While the motor performances and etficiency of submersible motors filled with standard clean water that does not contain solid particles are known, it is alsa very important to know the changes in etficiency and performance when the motor is filled with a mixture of antifreeze and water to protect from freezing in low external temperatures. in this line, experiments were conducted at the Alarko Carrier Submersible Motors Test Laboratories (*), using Alarko AL-6 submersible motors to the standard of IEC 60034-2 and an attemptwas made to define the changes in motor etficiency and performance with ditferent antifreeze - water ratios. "Ceram" Wastewater Advancement Station with Cladding System ..........................................................................132 The Tuzla Wastewater Refining Facilities / Pendik X5 Advancement Center has the characteristic ofbeingTurkey's first and only raw wastewater advancement station with Ceram cladded pump system. There are three Wilo Submersible Wastewater pumps with a capacity of 2,900 m3/hours each working at the X5 Advancement Station established on the Pendik coastal road. 8 Tesisat Dergisi Sayı 152 - Ağustos 2008
