This paper is concerned with the optimisation oil some design criteria
of SHW systems intended for residential and hotel applications. For t
his purpose, a system model based on TRNSYS programme has been used to
correlate the performance and cost effectiveness of the system with a
number of key design criteria which include the Collector to Consumer
Factor (FCC) expressed in m(2) of collector per consumer and the Coll
ector to Load Factor (FCL) expressed in m(2) of collector per annual G
J of thermal load.
