PENGARUH TEMPERATUR UDARA TERHADAP UNJUK KERJA UNIT DESALINASI BERBASIS POMPA KALOR DENGAN MENGGUNAKAN PROSES HUMIDIFIKASI DAN DEHUMIDIFIKASI
Abstract: Desalination unit
based on heat
pump with humidification and dehumidification processes
was one of the heat
pump applications system, with
addition of a
humidifier, sprinkler and
evaporator (dehumidifier) that integrated in
a unit. In
this unit, evaporator
of heat pump
was used for dehumidification process which
would produce fresh
water from the air that has been humidified in the
humidifier with the spray of sea water through the sprinkler. The
addition of electric
air heater was
used to vary
the inlet air temperature to the humidifier on this
system. In this research was examine the effect
of air temperature
on the performance
of desalination unit
based on heat pump with
using humidification and
dehumidification processes. In this research
the air temperature
was varied at 35oC, 45oC, 55oC and 65oC, sea water
temperature was conditioned
at a constant
temperature of 35oC, and ambient
temperature was kept
constant. Compressor was
operated at a constant rotation of 1,200 rpm, the sea
water volumetric flow rate was kept at 300 l/h,
and sea water
in this system
was recirculated. The
result of this research
showed that the
volume of fresh
water production increase
with increasing the inlet air temperature to the humidifier on this
desalination unit.
