Briefs from lmportant Subjects lnvestigation of the Corosion Protection Program in the Open Cooling Tower and lnstallation Circuit .....................................................................52 in !his study, the general structure of corosions in open cooling towers and installation circuits, corosion effects of water and the implementation method that is necessary to prevent these affects has been investigated. The deposit that accelerates corosion, scaffolding and !he quality and quantity of the microbological evolution processes are subject to another study, thus !hey are not examined here. 0nly the effects of these factors on corosion, the corosion process and the protection method are assessed. The open cooling tower no. 4 in the Capitol Shopping Centre in lstanbul has been investigated with the aim to examine the corosion in installation circuit. A New Technology for the Renovations in the Current Radiator Structures; Heat Pumpsthat Can Produce High Water Temperature...........................74 Air to water heat pump systems are earning more and more popularity as alternative systems !hat present energy productivity with each passing day, compared to classical natural gas and liquid fuel systems. A new heat pump system has been developed with high water temperature to meet !his gigantic market demand. This new technology consists of two different cooler circuits operating as rigid systems and !his feature of it turns the system into an ideal solution tor high temperature implementations. The Biggest Court House of the World: Court House of the Anatolian Side - Kartal ...............................................................................90 Abdullah Bilgin and Mahmut Ayık designed the mechanic installation of the Court House of !he Anatolian Side which will be the biggest court house of the wortd, when il will be completed in March 2011, with its closed construction area of 359.208 m2 . 0etailed information regarding the mechanic installation of the projeci has been written by the designers of Abdullah Bilgin and Mahmut Ayık. 0ther information about the projeci has been provided by Mustafa Güray, the representative of Şira Elektrik İnş. Taah. Ltd Şii. Ali Fuat Kolaçan and Soner Canderler, as representatives of Alarko Carrier San. ve Tic. A.Ş., has laken part in the phases of material supply of !he projeci and !hey have carried out the productivity analysis which compares the enterprise costs of centrifuge cooling groups with or without frequency conventor. Designs for Solar Powered Coolers with Adsorption .............................. 104 in our country and the world, both domestic and commercial applications of refrigerators using electrical energy driven compressors and refrigerant having the different features are widely used. The use of !his type of cooling system have indirect and direct negative effects on the natural environment. Solar energy used in the refrigerator design is very attractive and in terms of solar energy our country is very advantageous. Refrigerators designs compatible with !he environment can be made by using solar energy with sorption technology. Solar energy adsorption refrigerators is an alternative lor these designs. in !his study, the working principles and designs of solar energy adsorption refrigerator operating with !he basic adsorption cycle with a single and two adsorbent beds has been presented tor consideration. The Use of Horizontal National Pumps as Fire Pumps ........................... 122 in !his article, the features !hat have to be present in the horizontal national fire pumps according to the American Fire Standarts, are examined in terms of construction, material and hydrolic performances. The standarts of NFPA 20, UL 448, FM 1311 have also been investigated and the construction, material and hydrolics performance features !hat horizontal national fire pumps must own have been added to the scope of this article.
