Abstract

 

A detailed design of the evacuated tube collectors is enumerated followed by the thermal network analysis of this collector. The temperature of each component is determined empirically. Numerical analysis is applied to find the coefficient of heat transfer across the air gap from absorber plate to the copper tubes. The performance characteristics of these collectors are analyzed and compared with commercially available brands to test their capability to power the generator of an absorption chiller. The generator of a typical 1 KW capacity refrigeration system is designed based on the hot water made available from outlet of evacuated tube collectors.

 

Key words: Evacuated tubes, heat transfer applications and absorption chiller.
