Abstract
U radu su prikazani rezultati mjerenja provedeni na kompaktnoj izvedbi solarne dizalice topline s direktnim isparavanjem radne tvari u solarnom kolektoru. Dizalica topline služi za zagrijavanje potrošne tople vode. Mjerenja su provedena tokom sunčana i oblačna vremena u kalendarski hladnom dijelu godine. Dobiveni rezultati su analizirani te su neki poslužili za izradu termodinamičkog proračuna isparivača i kondenzatora. Zbog nepoznatih karakteristika kondenzatora proveden je poračun potrebne duljine cijevi kondenzatora. Potvrđena je pretpostavka da ugrađeni izmjenjivač ima dovoljno veliku izmjenjivačku površinu. Provedena je simulacija cjelogodišnjeg rada sustava pomoću jednostavnog matematičkog modela. Podudaranja s mjerenim rezultatima nisu potpuna zbog jednostavnosti modela. Izračunati sezonski toplinski množitelj okvirno pokazuje da rad sustava može biti isplativ tokom cijele godine.
Abstract (english)
In this paper are presented results of the measurments on compact design solar assisted heat pump with direct expansion of refrigerant in the solar collector. Heat pump is used for production od domestic hot water. Measurments were carried out during sunny and cloudy conditions in the winter days. Results were analysed and were used for thermodynamic calculation of the evaporator and condenser. Because of unknown characteristic of a condenser, calculation of required condenser pipe lenght was conducted. The assumption is confirmed that the built- in heat exchanger has sufficient heat surface. Year-round operation of the system was carried out using simple mathematical model. Matching with the measured resulte aren't complete due to simplicity of the model. Seasonal coefficient of preformance is calculated and it indicates that operation of the system can be cost effective throughout the year.
