Abstract

U okviru ovog rada razvijen je matematički model energijske i eksergijske analize pripreme vlažnog zraka za zagrijavanje prostora u zimskim uvjetima. Matematički model obuhvaća sve relevantne jednadžbe koje proizlaze iz energijske i masene bilance postavljene za svaki segment procesa pripreme vlažnog zraka, kao i odgovarajuće jednadžbe koje za svaki segment procesa opisuju nastalu eksergijsku destrukciju. U okviru zadatka pokazano je kako eksergija vlažnog zraka ovisi o toplinskoj, mehaničkoj ali i kemijskoj neravnoteži s okolišem. Glavni cilj zadatka je pronalaženje funkcijske ovisnosti eksergijske destrukcije pojedinog procesa, kao i eksergijski stupanj djelovanja cjelokupnog procesa o masenom udjelu suhog zraka iz prostorije, te njihov dijagramski prikaz kako bi se mogli međusobno usporediti pojedini procesi pripreme vlažnog zraka.

Abstract (english)

In this papera mathematical model is developed for the energy and exergy analysis with moist air for space heating in winter conditions. The mathematical model includes all relevant equations arising from the energy and mass balance configured for each segment of the preparation process of moist air, as well as the corresponding equations for each segment of the process describing the resulting exergy destruction. As part of the task has been shown to Exergy moist air depends on the thermal, mechanical or chemical imbalance with the environment. The main objective of the task is to find the functional dependence of Exergy destruction of a single process, and the exergy efficiency of the overall process of the mass fraction of dry air from the room, and their diagrammatic view in order to compare each individual processes with moist air.
