Abstract
Za potrebe transporta kvarljive hrane projektiran je rashladni kontejner s integriranim rashladnim sustavom. Prema proračunu toplinskog opterećenja odabran je kontejner rashladnog kapaciteta od 5 kW pri temperaturi isparavanja od -6 °C i temperaturi kondenzacije od 55 °C. Prema važećim zakonskim regulativama odabrana je radna tvar R-1234yf s niskim GWP brojem. Rashladni sustav kontejnera hladi zrak na isparivaču, koji se preko T-poda upuhuje u teretni prostor te preuzimanjem topline na sebe hladi teret. Kondenzator rashladnog sustava hlađen je okolišnim zrakom. Za rashladni sustav napravljen je termodinamički proračun komponenti, kako bi se odredile potrebne dimenzije komponenata te njihovi kapaciteti te je također napravljena shema spajanja i regulacije. Također je provedena analiza rada kondenzatora u sustavu pri promjenjivoj temperaturi okoline. Na kraju rada projektirana je mjerna linija za rashladni sustav, te je odabrana mjerna oprema koja omogućuje bilanciranje energetskih tokova i praćenje parametra rada sustava.
Abstract (english)
For the transportation of perishable food, a refrigerated container with an integrated refrigeration system has been designed. According to the heat load calculation, a container with a cooling capacity of 5 kW at an evaporation temperature of -6 °C and a condensing temperature of 55 °C was selected. According to the valid legal regulations, the working substance R-1234yf with a low GWP number was selected. The cooling system of the container cools the air on the evaporator, which is then blown into cargo space via the T-floor. Cold air cools the cargo by taking the heat on itself. The condenser of the cooling system is cooled by ambient air. For the cooling system, a thermodynamic calculation of the components was made, in order to determine the required dimensions and capacities. A connection and regulation scheme was also made for the designed cooling system. A parametric analysis of the condenser under different environmental conditions was also made. A measuring line has also been designed for the cooling system and measuring equipment has been selected in order to balance the energy flows in the system. Measuring equipment also allows monitoring of the system parameters during operation.
