| Summary: | The Solar Assisted Heat Pump (SAHP) desalination,
based on the Rankin cycle operates in low temperature and
utilizes both solar and ambient energy. An experimental SAHP
desalination system has been constructed at the National
University of Singapore (NUS). The system consisted of two main
sections: a solar assisted heat pump and a water distillation
section. Experiments were carried out under the different
metrological condition of Singapore and results showed that the
system had a performance ratio close to 1.3. The heat pump has a
Coefficient of Performance of about 8, with solar collector
efficiencies of 80% and 60% for evaporator and liquid collectors,
respectively. Economic analysis showed that at a production rate
of 900 liter/day and an evaporator collector area of around 70 m2,
will have a payback period of about 3.5 years. |
