The rate of agricultural and horticultural waste is high in Iran, and one of the best preventive methods is to convert fruits and crops to the products which have long shelf life and high quality. Traditionally apricots are dried in front of sun with excessive sulfuring which is proved to be harmful for human. In the current study apricots were dried by either solar tunnel dryer or conventional...

Existing design of Heat-Pipe Evacuated Tube Collector (HP ETC) for solar water heating require storage tank and additional heat exchanger required air application which leads to the extra spacing costing requirement. HP ETC have better thermal performance produce high outlet temperature than flat plate collector (FPC), especially during diffuse radiation. But normally focusing on system. Furthe...

to increase agricultural crops’ quality and to minimize losses in the final product and used energy during the drying process, major drying system parameters should be continuously controlled. precise control of such parameters is attained by using automatic control systems. to optimize the overall dryer efficiency in a forced convective solar dryer, a controller was designed, constructed a...

A typical solar domestic water heating system suffers from low energy efficiency due to multiple heat transfer process among components, i.e., the thermal collector and storage. In this work, a compact design of storage-integrated its compatible phase change material (PCM) storage were explored. The salt hydrate based composite PCM, sodium acetate trihydrate (SAT), was used create shape stabili...

Provision of potable water from brackish or saline feed is a challenge in households remote off-grid islands and coastal areas. An effort to study small-scale desalination system comprising an evacuated tube collector (ETC) basin air-cooled condenser with the ultimate goal produce fresh decentralised manner has been carried out this work. Experiments were performed on solar distillation unit co...
