Dynamic Modeling and Simulation of Two-phase Evaporators and Condensers in the context of a CO2 Based District Energy Network
François Maréchal, Daniel Favrat, Samuel Henchoz
A new type of district energy network has recently been proposed that is based on the use of CO2 as a heat transfer fluid. It uses the latent heat of vaporization, instead of sensible heat, to store and transfer heat. Previous studies have focused on demon ...
2013Theoretical and Experimental Study of a Thermally Driven Heat Pump Based on a Double Organic Rankine Cycle
Nowadays, one of the main alternatives for a more rational use of energy in heating applications is the heat pumping technologies. The market is dominated by two kinds of heat pump systems: the electrically driven vapor compression heat pumps (EHP), which ...
EPFL2012DYNAMIC MODELING OF HEAT PUMP COMPONENTS AND CIRCUITS
The report describes the implementation of a radial micro-compressor in the dynamic modeling software PSE gProms, the development and the implementation of a two-phase flow pipe model, and the preliminary design of a two-phase flow dynamic heat exchanger ...
2012Hydrodynamics of a Pump-Turbine Operating at Off-Design Conditions in Generating Mode
Modern pump-turbines are subject to frequent switching between the pumping and generating modes with extended operation under off-design conditions. Depending on the specific speed of the pump-turbine, the discharge-speed as well as torque-speed generating ...
EPFL201220 ans de contribution du LENI-EPFL à la recherche sur les pompes à chaleur
Throughout the years LENI-EPFL spent a significant part of its research activities on heat pumps be it for industrial heat recovery or for domestic or district heating and cooling. Methodological contributions include the improvement of the formulation of ...
