Analysis of evaporation heat transfer and design of evaporator

U ovom radu analizirani su koeficijenti prijelaza topline u shell and tube i pločastom isparivaču s propanom kao radnom tvari. Napravljen je termodinamički proračun shell and tube isparivača te je dana usporedba raznih modela koeficijenata prijelaza topline. Napravljen je hidrodinamički proračun, a na kraju i proračun čvrstoće prema čijim je rezultatima isparivač konstruiran. Termodinamički i hidraulički proračun provedeni su za pločasti isparivač te je dana usporedba koeficijenata prijelaza topline prema različitim modelima. Naposljetku je dana kratka financijska analiza i usporedba shell and tube i pločastog isparivačaThe thesis analyzes heat transfer coefficients in shell-and-tube and plate evaporators with propane as refrigerant. A thermodynamic calculation of the shell-and-tube evaporator was performed to compare different models of heat transfer coefficients. A hydrodynamic and a strength calculation were then performed, the results of which were used to construct the plate evaporator. Thermodynamic and hydraulic calculations were performed for the plate evaporator, followed by a comparison of heat transfer coefficients for different models. Lastly, a brief financial analysis and comparison of shell-and-tube and plate evaporators were given
