20.500.12556/DKUM-22949 UPORABA TOPLOTNIH ČRPALK V TEHNIKI SUŠENJA PERILA THE APPLICATION OF HEAT PUMPS IN LAUNDRY DRYING METHODS Magistrsko delo predstavlja dva vidika energetsko trenutno najučinkovitejših sušilnikov perila, to so sušilniki, s toplotno črpalko. Eden izmed teh dveh vidikov je vpogled v zakulisje s strani proizvajalca, kjer se srečujemo z velikim številom problemov pri samem razvoju in dimenzioniranju sistema toplotne črpalke in seveda vseh ostalih komponent. Najprej smo predstavili sušilnike perila, ter njihovo delovanje. Prav tako smo predstavili toplotne črpalke, kjer smo na kratko pogledali njihovo delovanje in tipe ki jih poznamo. Kratko predhodno predstavitev obeh sistemov smo naredili za lažje kasnejše razumevanje pri združitvi obeh sistemov med sabo v en aparat. Predstavili smo različne rezultate meritev na izdelanih prototipih, na katerih smo izvajali meritve porabe energije in časa sušenja. Naredili smo tudi primerjalno analizo delovanja TČ v sušilniku, začetnega sistema in končnega sistema, ki nam zagotavlja želeni cilj. Primerjalno smo naredili še teoretični preračun, s potencialno uporabo drugega plina R134a, namesto uporabljenega R407C. V nalogi smo se dotaknili še ekonomske analize s področja uporabnika, s trenutnimi cenami aparatov na trgu in trenutno ceno električne energije. Predstavili smo teoretične stroške za porabljeno električno energijo na letne ravni, za posamezne aparate. Na podlagi teh stroškov smo predstavili v kolikšnem času bi se nam amortizirala razlika v ceni pri nakupu sušilnika s TČ, namesto sušilnika z električnimi grelcem pri različni uporabi aparata. Two aspects of actually most energy efficient dryers – heat pump dryers, are presented in this master’s thesis. One of the aspects is the insight into the manufacturer’s backstage where we stumble upon numerous troubles in the development itself and dimensioning of heat pump and of course, all other component parts. First we presented the dryers and their operation. We also briefly described the operation of heat pumps and indicated the known types of heat pumps. The short description of both systems has been made for later easier understanding of joining of both systems into one appliance. Different results of measurements carried out on prototypes (energy consumption and drying time) are presented in the thesis. We have also made a comparative analysis of operation of heat pump in the dryer, of the starting system and of the final system, which assures the desired scope. For comparison we have also made a theoretical calculation with the potential use of another gas R134a, instead of R407C. The thesis also contains the economic analysis from the point of view of user, with actual prices of appliances on the market and actual price of electric energy. Theoretical costs for the used electric energy on annual basis for individual appliances are presented. On the basis of these costs we calculated in what period of time the difference in price if purchasing the heat pump dryer instead of dryer with electric heater would pay off, at different use of the appliance. toplotna črpalka sušilniki perila uporaba toplotnih črpalk heating pumps tumble dryers heating pump usage true true false [I.
