Abstract

Tema završnog rada je pregled tehnologija hlađenja te usporedba pogona rashladnih kompresijskih sustava u transportu. Projektiran je rashladni kompresijski sustav dostavnog vozila rashladnog učinka 5 kW pri temperaturi isparavanja od -6 °C i pri temperaturi kondenzacije od 50 °C. Proces hlađenja je direktan, što znači da odabrano rashladno sredstvo propan (R290), hladi zrak koji nastrujava na proizvode koji se nalaze u rashladnom prostoru. Rad obuhvaća proračun toplinskih opterećenja rashladnog prostora, termodinamički proces te izračun učina kondenzatora i snage kompresora. Provedena je analiza potrošnje pogonske energije rashladnog kompresijskog sustava pri različitim temperaturama okoliša na dnevnoj i godišnjoj razini kao i usporedba emisija CO2 kada je isti rashladni kompresijski sustav pogonjen motorom s unutarnjim izgaranjem i baterijskim modulom.

Abstract (english)

The topic of the thesis is a review of cooling technologies and a comparsion of a propulsion systems of refrigeration compression systems in transport. A refrigeration compression system with a capacity of 5 kW at an evaporation temperature of -6 °C and a condensation temperature of 50 °C was desgined. The cooling process is direct, meaning the selected refrigerant, propane (R290), cools the air flowing over the products located in the refrigerated space. The work includes the calculation of thermal loads of the refrigerated space, the thermodynamic process, the calculation of condenser efficiency and the power of the compressor. An analysis of the electric energy consumption of the refrigeration compression system at different ambient temperatures on a daily and yearly basis was conducted, as well as a comparsion of CO_2 emissions when the same refrigeration compression system is powered by an internal combustion engine and a battery module.
