文摘

A domestic solar combined heat & power (S-CHP) system is optimised for maximum electrical output in the UK. The S-CHP system comprises a solar collector array, an ORC engine and a working fluid buffer vessel. A working fluid and evaporation temperature optimisation are performed for an annual operation period. A single-stage and a two-stage collector array configuration are compared. An optimum annual-average electrical power of 122 W for the two-stage configuration is reported.
