Abstract

U ovome radu je prikazan projekt klimatizacijskog sustava centra za proizvodnju cjepiva. Zgrada se nalazi na području grada Zagreba, a svi referentni klimatski podaci potrebni za proračune definirani su za meteorološku postaju Maksimir. Projekt se sastoji od termotehničkog proračuna projektnog toplinskog opterećenja prema normi HRN EN 12831-1:2017 i projektnog rashladnog opterećenja prema normi VDI 2078:2015. Također, projekt se sastoji i od satnog proračuna toplinskih potreba za grijanje i hlađenje prvog kata zgrade korištenjem dinamičke satne metode prema normi HRN EN ISO 13790 te satnog proračun prema nacionalnom Algoritmu za proračun potrebne energije za primjenu ventilacijskih i klimatizacijskih sustava kod grijanja i hlađenja prostora zgrade za sustave 8 i 10 prema spomenutom Algoritmu. Laboratorij za proizvodnju lijekova pripada u kategoriju čistih prostora, pa će termotehnički sustav u ovome slučaju biti isključivo samo zračni sustav. Dobava i odsis zraka vršit će se pomoću centraliziranog klimatizacijskog sustava s klima komorom smještenom na vrhu zgrade te pomoću razvodnih dobavnih i povratnih kanala. Raspoloživi ogrjevni medij za sustav bit će topla voda u režimu 70/55 °C, dok će rashladni medij biti hladna voda s 30% otopinom etilen - glikola u režimu 7/12 °C. Energetski proračun daje mjesečne količine toplinskih potreba za elemente klima jedinice sustava 8 i 10 a to su: grijač, hladnjak, parni ovlaživač i dogrijač. Pokazalo se da postoji značajna razlika u energetskim potrebama za toplinskom energijom između ova dva sustava gdje su ukupne potrebe kod sustava 10 značajno veće zbog cjelogodišnjeg održavanja vlažnosti zraka u zoni proizvodnje cjepiva.

Abstract (english)

In this paper, the project of an air conditioning system for a vaccine production center is presented. The building is located in the city of Zagreb, and all the relevant climate data necessary for calculations are defined for the meteorological station Maksimir. The project includes the thermodynamic calculation of the design heat load according to the HRN EN 12831-1:2017 standard and the design cooling load according to the VDI 2078:2015 standard. Additionally, the project involves an hourly calculation of heating and cooling needs for the first floor of the building using the dynamic hourly method according to the HRN EN ISO 13790 standard. It also includes an hourly calculation according to the national Algorithm for the calculation of energy needs for the application of the air conditioning systems for heating and cooling of buildings. The laboratory for vaccine production is categorized as a clean room, so the air conditioning system in this case will exclusively be an air system. The supply and exhaust of air will be done through a centralized air conditioning system with an air conditioning chamber located on the top of the building, using distribution supply and return ductings. The available heating medium for the system will be hot water in a 70/55 °C regime, while the cooling medium will be cold water with a 30% ethylene-glycol solution in a 7/12 °C regime. The energy calculation gives the monthly amount of thermal energy needs for the elements of the air conditioning unit of system 8 and 10, which are: heater, cooler, steam humidifier and reheater. It has been shown that there is a significant difference in the energy needs for thermal energy between these two systems, where the total needs for system 10 are significantly higher due to the year-round maintenance of air humidity in the vaccine production zone.
