Abstract
Energetsko-ekonomska analiza opskrbe potrošača rashladnom energijom centraliziranim sustavom hlađenja u Gradu Zagrebu napravljena je s ciljem ispitivanja potencijala daljinskog hlađenja i pronalaska najoptimalnijeg oblika proizvodnje i distribucije rashladne energije. U radu su navedena i objašnjena sva prikupljena iskustva i podaci o načinu proizvodnje, skladištenju, distribuciji i potrošnji rashladne energije te ekonomski modeli sustava daljinskog hlađenja u svijetu. Proveden je detaljan uvid u potencijalne potrošače koji se nalaze na lokacijama u blizini proizvodnih pogona EL-TO i TE-TO te pregled karakteristika proizvodnih procesa u navedenim proizvodnim pogonima kao i zakrčenost podzemne infrastrukture koja će definirati potencijalnu trasu za polaganje distribucijskog cjevovoda hladne vode. Na osnovu prikupljenih i detaljno proučenih podataka, definirane su tehnologije proizvodnje rashladne energije i pet različitih slučajeva opskrbe potrošača rashladnom energijom centraliziranim sustavom hlađenja; Decentralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom – Radnička cesta, Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji TE-TO – Radnička cesta, Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji TE-TO – Sveučilišna aleja, Decentralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenih vrelom vodom – Sveučilišna aleja, Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji EL-TO. U slučajevima „Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji TE-TO – Radnička cesta „ i „Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji TE-TO – Sveučilišna aleja „ koristi se rashladni učinak rijeke Save za hlađenje u mjesecima travanj i listopad. Prva četiri od pet navedenih slučajeva detaljno su dinamički modelirani u računalnom programu TRNSYS, te su njihovo ponašanje i odzivi promatrani na razini od 20 sekundi tijekom cijele sezone hlađenja (od početka travnja do zaključno listopada). Iznimku predstavlja slučaj „Centralizirana proizvodnja rashladne energije apsorpcijskim rashladnim uređajima pogonjenim vodenom parom na lokaciji EL-TO“ gdje je dinamika sustava opisana pomoću bezdimenzijskih veličina dobivenih iz prethodnih slučajeva.
Abstract (english)
The energetic and economic analysis of district cooling system in town of Zagreb was made with the aim to analyze district cooling potential and find the optional solution for producing and distributing cooling energy. In this work, collected experiences and data about producing, storing, distributing and consuming cooling energy are listed and explained as well as economical models of district cooling system around the world. Detailed analysis of potential consumers located round cogeneration plants EL-TO and TE-TO is carried out and production processes of mentioned plants reviewed. Furthermore, detailed analysis also includes investigation of underground infrastructure congestion in order to define district cooling pipe route. Optimal choosing of cooling technology and five different cases of supplying consumers with cooling energy are based on collected and comprehensively analyzed data. Analyzed cases are: Steam fired absorption chillers used for decentralized production of cooling energy – Radnička Street, Steam fired absorption chillers used for centralized production of cooling energy located at TE-TO plant – Radnička Street, Steam fired absorption chillers used for centralized production of cooling energy located at TE-TO plant – Sveučilišna alley, Hot-water fired absorption chillers used for decentralized production of cooling energy – Sveučilišna alley, Steam fired absorption chillers used for centralized production of cooling energy located at EL-TO plant. In cases: Steam fired absorption chillers used for centralized production of cooling energy located at TE-TO plant – Radnička Street and Steam fired absorption chillers centralized production of cooling energy located at TE-TO plant – Sveučilišna alley cooling load during months of April and October is satisfied with the cooling effect of Sava river. First four of five listed cases are modeled and dynamically simulated using TRNSYS software with simulation time step of 20 seconds. Simulations were performed for each month of the cooling period (from the beginning of April until end of October). There is an exception in the case Steam fired absorption chillers used for centralized production of cooling energy located at EL-TO plant - system behavior was described using only dimensionless quantities calculated from previous cases.
