High temperature industrial heat pumps utilising natural working fluids
There is a large demand for heat typically in the temperature range 100-200⁰C in different industries. This is today often covered by fossil fuel burning or direct use of electricity. Heat pumps has to a lesser extent been utilized due to higher investment cost and limited availability of systems fo...

Investigation on scale formation in aluminium industry by means of a cold-finger
A cylindrical fouling probe or “cold-finger” has been used to investigate fouling from aluminium production off-gas. The probe was located upstream from the off-gas cleaning system. Surface deposits have been collected for further analysis by EPMA and XRD, and compared with off-gas dust and old scal...
Preliminary study on CO2 transcritical ejector enhanced compressor refrigeration system for independent space cooling and dehumidification
This study presents a single CO2 vapour-compression system for independent cooling and dehumidification of indoor air conditioning systems. A CO2 gas cooler outlet split (GOS) ejector system is introduced to generate two levels of evaporating temperature, and therefore indoor air temperature and hum...
