Analysis of a Flat-Plate Solar Collector Plok iojo saul s kolektoriaus tyrimas

The paper deals with a flat plate solar collector. The experiment was conducted using the finite element method and described the theoretical effectiveness of the flat solar collector as well as the factors that produce the major loss of heat. Investigation has concentrated on several different transparent surfaces used for determining the efficiency of the collector: 5 mm thick transparent glass and 5 mm thick transparent glass coated with a film of 120 μm. Article in Lithuanian Darbe tirtas plok iasis saul s kolektorius. Baigtini element metodu nustatytas teorinis saul s kolektoriaus efektyvumas ir did iausius ilumos nuostolius lemiantys veiksniai. Atliktas eksperimentas, kurio metu i tirtas kolektoriaus efektyvumas naudojant skirtingas skaidrias dangas: 5 mm skaidr stikl ir 5 mm skaidr stikl su 120 μm storio papildoma pl vele.
