The development of a hydrocarbon high temperature heat pump for waste heat recovery
Waste heat is an abundant resource that if recovered with a heat pump would increase energy efficiency in industrial processes. This will provide improvements in heat utilization and reduce the environmental impact of greenhouse gas emissions from the combustion of fossil fuel. A hydrocarbon high te...
Experimental investigation of a prototype R-600 compressor for high temperature heat pump
This research experimentally investigates a prototype compressor in a high temperature heat pump for industrial waste heat recovery from 50 °C to heat delivery at 115 °C. Compressors are the limiting component in the development of high temperature heat pumps due to the high discharge pres...

Experimental Investigation of a Hydrocarbon Piston Compressor for High Temperature Heat Pumps
Description of atmoshperic freeze-drying process of organic apples using thermo-physical properties
This study discusses the influence of temperature and total moisture content on ice fraction in organic apples during atmospheric freeze-drying process. The ice formation of glass transition events were described by Clausius- Clapeyron and Gordon Taylor equations. The obtained data is essential for ...
Description of atmospheric freeze-drying of brown seaweeds (Saccherina Latissima) with respect to thermal properties and phase transition
Thermal properties of brown seaweeds (Saccharina latissima) were determined using DSC technique in the temperature range between -150.0 and 50.0 °C. The following phase transitions were detected: glass transitions, incipient point of ice melting and freezing point. The ice content and amount of...
Investigation of influence of pre-treatment and low-temperature on drying kinetics, sorption properties, shrinkage and color of brown seaweeds (Saccharina Latissima)
Drying kinetics of Saccharina latissima (raw and blanched) at low temperatures (10.0, 25.0 and 38.0 °C) was studied. The effective moisture diffusivity coefficient varied due to temperature alterations in the range between 1.4 and 4.5 10-10 m2/s for raw and 0.91 and 2.56 10-10 m2/s for blanched...
Feasibility of Vis/NIR spectroscopy and image analysis as basis of the development of smart-drying technologies
Drying is a complex, dynamic, unsteady and nonlinear process that, when not optimized on a system level, may be responsible for (1) significant quality degradation and (2) energy wastage. Consequently, new drying technologies must be designed combining non-invasive at-/on-/in-line advanced measureme...
