Abstract
U ovom radu je, za potrebe visokotemperaturnog hlađenja u procesnoj industriji i sustavima komfornog hlađenja, konstruiran rashladnik vode učinka hlađenja 240 kW. Za zadane projektne uvjete odabrani su pločasti isparivač i mikrokanalni kondenzator. Zatim je napravljena postavka procesa kojom su određene karakteristične točke procesa. Uz poznata konstrukcijska rješenja isparivača i kondenzatora, te karakteristične točke i početne uvjete, proveden je termodinamički proračun isparivača i kondenzatora, pomoću kojeg su određene konačne dimenzije izmjenjivača. Nakon toga dimenzionirani su cjevovodi za protok radne tvari kroz rashladni agregat, te su odabrani odgovarajući kompresori. Kada je sustav potpuno definiran, provedena je energijska analiza i analiza učinkovitosti rashladnog agregata u radu kroz sezonu hlađenja u procesnoj industriji i sustavima komfornog hlađenja. Njome je obuhvaćeno ponašanje sustava pri različitim vanjskim uvjetima i različitim toplinskim opterećenjima. Za takav sustav prikazana je shema njegovog spajanja i regulacije potrebne da bi sustav radio kako je zamišljen. Na kraju je nacrtan dispozicijski crtež rashladnika vode.
Abstract (english)
In this bachelor's degree, for the need of high temperature cooling in process industry and comfort cooling systems, chiller with the cooling capacity of 240 kW was designed. For the given project conditions plate evaporator and microchannel condenser were selected. Subsequently, process setting was made with which caracteristic points were defined. With known construction solutions for evaporator and condenser, caracteristic points of process and the given project conditions, the thermodynamic problem was solved, and finite dimensions of heat exchangers were defined. After that, pipes were dimensioned for the coolant flow rate through cooling aggregate, and suitable compressors were selected. When the system was defined, energy analysis and efficiency analysis of the cooling agregate through cooling season in process industry and comfort cooling systems were carried out. The analysis involves behavior of the system at different outdoor conditions and different cooling loads. For this system sheme was shown with regulation needed for the system to work as intended. At the end, dispositional drawing of the chiller was drawn.
