A brine/water heat pump with the auxiliary liquid subcooling cycle with a heating capacity of 9 kW at -7/50°C was built and a series of measurement were conduced. The heat pump is designed for the monovalent heating in the retrofit market. For this purpose ...
Diesel-electric traction is a well-established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel-powered locomotive is due to the reduced costs compared to the infrastructure cost of ...
In this report different air-water heat pump cycles under the operating conditions of the retrofit market and in the low heating power range are examined. The already existing heat pump models show excessive power and efficiency loss at very low ambient te ...
Recent results from the ASDEX Upgrade experimental campaigns 2001 and 2002 are presented. An improved understanding of energy and particle transport emerges in terms of a 'critical gradient' model for the temperature gradients. Coupling this to particle di ...
