ANALISIS PERFORMANSI MODEL OVEN KAYU SISTEM INTEGRAL HP/T COLLECTOR DAN DESAIN REKAYASA PROTOTIPE HYBRID MOBILE WOOD DRYER
Abstract: The aim of this
research is to introduce applied technology and engineering design of hybrid
mobile wood prototype. Energy source of
the hybrid mobile wood dryer prototype
are heat pump
dryer and thermal
collector. That two
kind of energy source
is called integrated
system HP/T Collector.
The integrated system
HP/T Collector is a
technological innovation which
developed as a
device for wood drying process. The dried wood samples
are teak wood (Tectona Grandis Linn. F.) and mahony wood (Swietenia Mahagoni).
Material of thermal collector are a single flat black plate collector and a
glass cover. The heat pump dryer use a compres sion vapor system
with refrigerant R-134a
as working fluid.
The mechanism of combination integrated system HP/T
Collector operates during 12 hours per cycle. The heat pump dryer operates
during 2 hours respectively at the start and the end of drying
process. The thermal
collector dryer operates
during 8 hours
at the middle of
drying process. The
results of experiment
show that using
first combination is the
best performance. The
first combination has
useful energy 1995,279 J
and collector efficiency
32,6%. While, heat
performance of first combination have
0,139 kg water/hr
of MER, 33,5
% of SMER
and 4,26 - 3,49
COP actual. And the average of convection heat transfer show 26,556 (W/m2.°C)
for heat pump dryer unit and 40,884 (W/m2.°C) for thermal collector
unit.
