Pengaruh Water Storage Volume Terhadap Unjuk Kerja Solar Assisted Heat Pump Water Heater (SAHPWH) menggunakan HFC-134a
Abstrak: Solar assisted heat
pump water heater (SAHPWH) was one of the applications from heat pump system
with the solar collector addition on evaporator to absorb the heat from
sunshine. The solar collector aimed to
increase the refrigerant temperature in the evaporator. This research was
conducted to test the performance of
SAHPWH by using refrigerant HFC-134a with the variation of water storage
volume at 50 l, 75 l, 100 l, 125 l, and 150 l.
The experimental result showed that water storage volume enhancement was
caused COP increased whereas water
temperatur yielded decreased. When water
temperature in condenser tank increased with time, refrigerant mass flow rate,
heat capacity also increase, and at the
same time COP value decreased. Average values of COP ranged from about 3.75
– 4.74 and water temperature in condenser tank
varied between 29.0oC – 61.3oC.
