Abstract
U sklopu ovog rada analiziraju se karakteristike rashladnika vode. To su sustavi koji na bazi ljevokretnih kružnih procesa odvode toplinu sa vode koju je potrebno hladiti ostvarujući tako određeni rashladni učinak. U prvom poglavlju opisan je način rada rashladnog uređaja i navedene su opće energijske postavke koje omogućuju njegovu realizaciju. Također su definirani i parametri o kojima ovisi njegova efikasnost. U drugom poglavlju navedene su četiri glave komponente sustava, sa posebnim naglaskom na izmjenjivače topline i kompresor. Osim glavnih komponenata, navedena je i sigurnosna, kontrolna i regulacijska armatura. Ukratko je opisan i utjecaj izbora radne tvari na proces i dimenzioniranje. U trećem poglavlju opisani su regulacijski elementi rashladnog uređaja i način regulacije kompresora koji čini srce svakog sustava. U sklopu četvrtog poglavlja analiziran je rad rashladnika vode koji se koristi za hlađenje upravne zgrade Hrvatske Elektroprivrede. Pronađena je funkcijska ovisnost o pogonskim parametrima u programskom paketu MATLAB.
Abstract (english)
This thesis examines the characteristics of water chillers. These are the systems that remove heat from water and by doing so are achieving a specific cooling effect. First, cooling systems are introduced along with the fundamental principles that make the system possible and coefficient of performance is defined. In second chapter four main components of a cooling systems are introduced. Aside from main components, additional safety, control and regulation parts are mentioned. Thermodynamic properties of multiple refrigerants are discussed along with their influence on the system's dimensions. Third chapter describes regulation components. Finally, an analysis of water chiller used at the Hrvatska Elektroprivreda building is given. In MATLAB, a chiller performance is defined as a function of entry parameters.
