Investigation of salt contamination effects on the performance characteristics of the evacuated tubes solar water heater

Abstract EN

The influence of salt layer contamination of thickness below (2 mm) on solar evacuated tubes water heater performance parameters was investigated experimentally in several operating weather conditions on October and November 2011 at Baghdad location taking into consideration the effect of ambient conditions and collector inclination angle.

It was concluded that the salt thickness have a minor effect on the collector efficiency, water circulation in the tubes and the heat loss coefficient from the storage tank.

While on the other hand, the collector angle and the ambient have a greater effect on the above-mentioned parameters.
