\narticle compares the costs of producing cold in two variants of trigeneration systems: with a compressor chiller (driven
\nby an electric motor or mechanically from a gas turbine) and with a thermal chiller, driven by heat from exhaust
\ngases. Mathematical models with continuous time were used for the economic analysis. The main objective of the
\nanalysis was to calculate the unit cost of producing cold depending on such parameters as: fuel prices, electricity,
\nCO2 emission allowances, exhaust gas temperature, and investment outlays. The impact of these factors on the costs
\nof producing cold is difficult to analyze, but the mathematical models with continuous time and dimensionless
\nvariables used in this article enable universal comparisons for systems with different capacities. The calculation results
\nshow that the cost of producing cold is strongly dependent on the above-mentioned factors.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[4778,4776,4777,4775,4779,4679],"tematyka":[424],"class_list":["post-23239","artykul","type-artykul","status-publish","hentry","tag-compressor-chiller","tag-cooling-costs","tag-cooling-production","tag-economic-profitability","tag-thermal-chiller","tag-trigeneration","tematyka-sources-of-heat-and-electricity","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["ALEKSANDRA OTAWA"],"ptb_artykul_text_2":"10.36119\/15.2025.7-8.2","ptb_artykul_numer_miesi_cznika":"7-8\/2025 Instal pp.20-27","ptb_artykul_info_autor":"Dr in\u017c.
