The implementation of renewable thermal technologies in energy-intensive industrial processes, such as pasteurization in the food industry, is key to reducing dependence on fossil fuels and optimizing energy consumption. These solutions not only improve sustainability but also increase the competitiveness of production plants by reducing operating costs and strengthening compliance with climate targets. In this article, we present the case of a beverage company that has installed a high-temperature heat pump to power its juice pasteurization process. We analyze the results obtained in terms of efficiency, economic savings, and emission reductions, with a projected return on investment in just 4 years.<\/p>\n

Introduction<\/strong><\/p>\n The packaged beverage sector requires continuous and reliable thermal processes to ensure food quality and safety. The analyzed plant previously operated with a pasteurization system primarily based on fossil-fuel steam, which resulted in high energy consumption and a significant carbon footprint. This Efficiency Case Study shows the results of integrating an industrial heat pump with an existing ammonia refrigeration system, harnessing waste heat to drastically reduce fossil steam use and the process\u2019s energy consumption.<\/p>\n Supply temperature: >80 \u00b0C<\/p>\n<\/li>\n Heat pump capacity: 567 kWe<\/p>\n<\/li>\n Coefficient of performance (COP): >3.5 under industrial conditions<\/p>\n<\/li>\n Integration: Ammonia-based refrigeration system, also compatible with CO\u2082-cooled facilities<\/p>\n<\/li>\n Application: Preheating (25\u201360 \u00b0C) and pasteurization (62\u201368 \u00b0C) in a continuous process<\/p>\n<\/li>\n<\/ul>\n Total treatment time: 20\u201330 minutes, meeting 15\u201325 Pasteurization Units (PU).<\/p>\n Reduction in process energy consumption: 38%<\/p>\n<\/li>\n Fossil steam substitution: >56% replaced by renewable heat<\/p>\n<\/li>\n Direct contribution to decarbonization and compliance with food sector climate targets, aligned with Law 7\/2021 + PNIEC: GHG reduction of 23%, renewable energy share of 42\u201374%, and efficiency of 39.5% by 2030<\/p>\n<\/li>\n<\/ul>\n Return on investment: 4 years<\/p>\n<\/li>\n Recognition with Energy Saving Certificates (CAEs), enhancing economic feasibility<\/p>\n<\/li>\n High operational efficiency thanks to the recovery of residual refrigeration heat<\/p>\n<\/li>\n<\/ul>\n Greater independence from fossil fuels, reducing vulnerability to price volatility<\/p>\n<\/li>\n Technology compatible with different industrial chiller configurations, such as NH\u2083 and CO\u2082<\/p>\n<\/li>\n Compliance with stricter food safety and quality standards<\/p>\n<\/li>\n<\/ul>\n With this project, GDES strengthens its position as a benchmark in efficient, renewable thermal solutions adapted to the highest standards of the food industry.<\/p>\n <\/p>","protected":false},"excerpt":{"rendered":" Sorry, this entry is only available in Espa\u00f1ol.<\/p>\n","protected":false},"author":3,"featured_media":310169,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[113],"tags":[],"class_list":["post-310161","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-eficiencia-energetica-y-fotovoltaica"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\tSystem Features \u2013 Industrial Heat Pump<\/strong><\/h3>\n
