Techno-economic of solar drying systems with water based solar collectors in Malaysia: A review

The paper describes the techno-economic of solar drying system (SDS) with water based solar collector in Malaysia. In Malaysia, SDS has been great potential to be used in drying purpose, which is relevant to the local climate. The design, performance and economic analysis of four types SDSs with water based solar collectors in Malaysia were described, (1) SDS with hybrid PVT-mechanical heat pump, (2) SDS with chemical heat pump, (3) SDS with dehumidification system, and (4) Greenhouse SDS with heat exchanger. Economic indicators such as payback period (PP), net present value (NPV), and life cycle saving (LCS) were presented. In addition, the various performances analysis of SDSs with air based solar collectors was presented. The energy and exergy analysis of SDS with water based collector was presented. Moreover, the energy and exergy analysis of PVT water collector was presented.
