20.500.12556/DKUM-37941 Optimizacija prenosnikov toplote v toplotnih črpalkah: teorija in meritve Optimization of heat exchangers in heat pumps: theory and experiment V magistrskem delu sem obravnaval optimizacijo velikosti toplotnih prenosnikov v toplotni črpalki. Pri konstantnih obratovalnih pogojih, to je temperatura vode in slanice v uparjalniku in kondenzatorju, ter izbranem kompresorju sem analiziral različne velikosti toplotnih prenosnikov. Analiza tlačnih padcev je izvedena s teoretično-empiričnim izračunom, programskim paketom in meritvami. Primerjava rezultatov je pokazala odlično ujemanje. Izbira manjšega toplotnega prenosnika vodi k manjšim investicijskim in večjim obratovalnim stroškom, izbira večjega pa ravno obratno. Cilj naloge je najti optimalno velikost toplotnega prenosnika glede na investicijske in obratovalne stroške. The master thesis discusses the optimization of heat exchangers in heat pumps. I analyzed different sizes of heat exchangers at constant operating conditions, the temperature of water and salt-water in the evaporator and condenser with a specific compressor. The analysis was done with theoretical-empirical calculations, a software package and experimentation. The comparison showed really good matching. The choosing of a smaller heat exchanger led to lower investment and higher operating costs and vice versa. The objective of the thesis is to find the optimal size of a heat exchanger according to investment and operating costs. toplotna črpalka grelno število ploščni prenosnik toplote tlačni padec eksperiment heat pump coefficient of performance plate heat exchanger pressure drop experiment true true false [M.
