PURPOSE: A vacuum pipe type solar power collecting device is provided to prevent the leakage of thermal medium in the damaging situation by adapting a vacuum pipe method.
Dewar tube consists of inner and outer tubes which are made of borosilicate glass and selective absorbance is used to coat the outside wall of the inner tube to collect …
In this study, a three-phase SECS is presented herein to ameliorate the PQ of the grid and to suppress the leakage current. In the state-of-the-art literature [], the behaviours of the SECS in the presence of …
This paper investigates the leak failure of an austenitic stainless steel condenser tube observed during the hydrostatic test operation using visual inspection, scale analysis, and …
Evacuated tube solar collector is a type of passive solar water heater whose ultimate aim is to reduce the amount of heat loss to reach a hot water in contrast with flat plate …
In this study, an energy storage air-type solar collector was developed. Air was used as the heat transfer medium in the solar collector and a PCM core was designed and …
solid-liquid Phase Change Materials (PCMs) that are used for latent heat storage. The aim is to determine the appropriate materials for integration with the Evacuated Tube Solar Collector …
There are two main types of tubes that are used inside the collector which are glass-glass and glass-metal. The glass-glass version uses two layers of glass fused together at both ends. The double glass tubes have a …
