SIMULATION OF THE INFLUENCE OF OPERATING PARAMETERS ON THE PERFORMANCE OF THE ABSORPTION REFRIGERATION CYCLE AMMONIA − WATER

Raziskava vključuje teoretične osnove različnih zasnov absorpcijskih hladilnih naprav, primerjavo učinkovitosti (COP) absorpcijskih hladilnih naprav oziroma, delovnih snovi: NH3/H2O, NH3/LiNO3, NH3/NaSCN, CH3NH2/H2O, R22/DMEU, R32/DMEU, R124/DMEU, R152a/DMEU, R125/DMEU, R134a/DMEU, TFE/TEGDME, CH3OH/TEGDME in R134a/DMAC, ki se uporabljajo za hlajenje pod 0 oC, ter simulacijo vpliva obratovalnih parametrov na učinkovitost obratovanja enostopenjske absorpcijske hladilne naprave NH3/H2O z računalniškim programom Aspen Plus. COP obratovanja je odvisna od temperature generatorja, kondenzatorja, absorberja in uparjalnika.This thesis presents the theoretical bases of various designs of absorption refrigeration systems, comparison of the performance of the absorption refrigeration cycles and working fluids respectively: NH3/H2O, NH3/LiNO3, NH3/NaSCN, CH3NH2/H2O, R22/DMEU, R32/DMEU, R124/DMEU, R152a/DMEU, R125/DMEU, R134a/DMEU, TFE/TEGDME, CH3OH/TEGDME and R134a/DMAC. These are used for refrigeration temperatures below 0 °C. This thesis also presents the simulation of the influence of operating parameters on the performance of the single effect absorption refrigeration cycle NH3/H2O with the Aspen Plus computer program. The coefficient of performance (COP) was found as a function of the generator, condenser, absorber and evaporator temperatures
