Rancang Bangun Kolektor Pelat Datar Energi Surya Untuk Sistem Pengeringan Pasca Panen
Abstract: Solar energy can be
exploited directly and indirectly. Technology convert energy required to change
radiations solar become other form energy. One of conversion of energy is in
form of heat able to be used for the process of draining of agricultural production.
Process draining represents important activity during after crops to increase
the quality of agricultural product. Solar collector flat plate and temporary
heat storage has been studied in this experiment. Paraffin, as phase change
material (pcm) is used as a working
object in storage system. Storage system and solar collector isolated by glass
wool, so heat transfer to surroundings could be minimizes. Storage capacity pcm
is 2525 kj by melting time is 3 hours and 8 minutes in temperature melting. Experimental
data acquisition research shows that its have the same average temperature in
the room of dryer (= 69 , =61.5). The average efficiency from solar collector
storage system is about 44,7% and efficiency theory is 50,5%. So based on this
experiment, storage pcm solar collector system can be used as heat storage by
increased source heat air and restore on it, and can be used again after head
air source decreased. Dimensions solar collector flat plate and temporary heat
storage system are 1000mm × 1000mm × 200mm and 5 copper pipes by diameter 15 mm
for paraffin storage.
