Käesoleva töö eesmärk oli uurida taastuvate energiaallikate, päikese- ja tuuleenergia kasutust
sooja tarbevee soojendamisel. Töös uuriti vajaminevat elektrienergia hulka soojaveeboileri
püsivaks toiteks. Töö autor uuris, kui suurt osa tarbitavast energiast on võimalik katta
taastuvenergiaallikatest. Samuti on uuritud soojaveeboileri soojuskadusid.
Töös on jõutud järeldusele, et juhul kui tuuleenergia arvutuslik tootmismaht on skaleeritud
samale tasemele soojaveeboileri tarbimisega, on võimalik efektiivselt varustada
energiatarbimine tuuleenergiaga seitsmel kuul aastas. Lisaks on ka välja selgitatud, et
skaleerides päikeseenergia arvutuslik tootmismaht samale tasemele soojaveeboileri
tarbimisega, on võimalik efektiivselt varustada energitarbimine päikeseenergiaga kuuel kuul
aastas. Välja on ka selgitatud elektrienergiahulgad, mida on vastavalt erinevatele tingimustele
tarvis võrgust osta, või võrku müüa. Samuti on ka välja arvutatud töös kasutatud analoogse
soojaveeboileri energiakaod. Sõltuvalt eelnevatest põhjustest, on hoone tarbevee
soojendamine tugevalt sõltuvuses ühendusest üldvõrguga.
This thesis has been written to examine the usage of renewable sources to provide hot tap water in a household. This thesis researches the amount energy that is required to provide continous supply to hot water heater. The thesis examines how big can be the fraction of energy consumption provided by renewable energy sources. Also, heat losses in hot water heater is examined. In this thesis it is concluded that when the wind power production is scaled to the same level as water heater consumption, it can efficiently provide all the needed electricity 7 months per year. It is also concluded, that when the solar power production is scaled to the same level as water heater consumption, it can efficiently provide all the needed electricity 6 months per year. Due to these reasons, supply of hot water heater is heavily dependant on main electrical grid. In the calculations, the weather data is acquired from meterological databases by hourly time series of data in 2010.
