Within the research work presented, a small test rig was used to
investigate the concept of a solar driven SJEC with parabolic trough
collectors. The operational behaviour of the test rig is described by
the efficiency g of the solar collector and the COP of the SJEC. The
SEJC shows high COP-values at low condenser pressure pc related
to good re-cooling conditions and in part load when the cold water
temperature can be increased. In view of a typical demand of a cold
supply, with low operating time at full load and governing part
load with good re-cooling conditions over the year, a high yearly
mean COP is expected.
