PENGARUH VARIASI WARNA PLAT KOLEKTOR SURYA TERHADAP KINERJA PEMANAS AIR TENAGA SURYA
Abstract: Solar water
heater is a device that heats water using solar collectors as a heat absorber of solar
radiation that is transmitted
to the pipe containing water . In
this research, comparative performance
testing of solar water heating to solar collector plate color variations
. Variations of color used is black ( black ) no. ( 39 ) with the brand of
quick drying formula zuper spray acrylic spray paint , red ( red signal ) no. (
23 ) with rj LONDON acrylic paint brand epoxy spray paint , and blue
( blue fluorescent ) no.
( 1004) with rj LONDON acrylic paint brand spray paint epoxy Data
collection was performed by taking data
every 30 minutes for 3 hours are 9:00 to
12:00 pm at the clock and the test performed 3 times on different days . Data
taken from the study include inlet and outlet water temperature collectors ,
and the temperature of the water in the tank , which is then carried out data
processing to determine the
flow rate , the density of water , the
water temperature difference in and out
collector ( ÄT )
, the performance of solar water
heaters ( q ) ,
and processing the data graphically .
The results of the study of each color plate solar collector plate showed that
the color black has the highest absorption compared with red and blue , because
the color black has emissivity close to 1 ( objects that are almost black) is a
transmitter as well as a good heat absorber.
