Abstract

V diplomski nalogi, ki smo jo izdelali v sodelovanju s podjetjem Gorenje d.o.o., smo na podlagi rezultatov eksperimentalnega dela analizirali vpliv hladilnih sredstev R134a in R450A na učinkovitost toplotne črpalke v sušilnem aparatu. Napravljenih je bilo več ponovitev eksperimenta iz katerih smo izbrali dve reprezentativni meritvi in ju med sabo primerjali. V rezultate so zajeti vsi merjeni parametri ter izračunane veličine za primerjavo učinkovitosti toplotne črpalke. Ugotovili smo, da je toplotna črpalka s hladilnim sredstvom R450A, pri danih pogojih, energijsko bolj učinkovita. Čas sušilnega cikla pa se napram delovanju toplotne črpalke s hladilnim sredstvom R134a podaljša.

Secondary title: Comparison of refrigerent R134a and R450A influence on the heat pump performance in a tumble dryer
Secondary abstract: In the thesis, which was made in cooperation with Gorenje d.o.o., we analyzed the influence of refrigerants R134a and R450A on the heat pump performance in a tumble dryer. Comparison of the refrigerants was based on the results of experimental work. Several measurements were carried out, from which we selected two representative measurements and compared them. The results include all measured parameters and calculated values to compare the efficiency of the heat pump. We found that the heat pump unit with refrigerant R450A is more energy efficient. But time of drying cycle in respect to heat pump unit operating with refrigerant R134a is extended.
