Turbocompressors for Domestic Heat Pumps – A Critical Review

Jürg Alexander Schiffmann, Jean-Baptiste Carré

Small-scale, oil-free radial compressors on gas lubricated bearings represent a promising alternative to state-of-the-art compressor technology for driving domestic sized heat pumps. The inherent characteristics of turbocompressors manage to fit the heat p ...

The offshore plant equipment usually has a long life cycle. During its O&M (Operation and Maintenance) phase, since the accidental occurrence of offshore plant equipment causes catastrophic damage, it is necessary to make more efforts for managing critical ...

Hindawi Limited2016

Hybrid absorption heat pumps (Osenbrück cycle and Hybrid wet compression cycle) are known for high temperature lifts, low-pressure ratios and wide capacity control. They are well suited for processes with the occurrence of significant heat sink and heat so ...

Energetic Macroscopic Representation of A Linear Reciprocating Compressor Model

Alfred Rufer, François Gallaire, Philippe Barrade, Mahbod Heidari

This article introduces the energetic macroscopic representation (EMR) as approach for the dynamic nonlinear modeling of a reciprocating air compressor. EMR has been introduced recently for research development in complex electromechanical systems and is b ...

Elsevier2015

The development of an efficient isothermal turbine and compressor is essential for the realization of a small-scale compressed air energy storage (CAES). This article presents the theoretical development of an oil-free co-rotating scroll air compressor and ...

Bond Graph Model Representation of a New Reciprocating Finned Air Compressor

Alfred Rufer, Mahbod Heidari

A new finned reciprocating air compressor model is developed recently for compressed air energy storage. First the mechanism of operation of the new compressor is described. The complexity of the design encouraged us to develop the model based on the bond ...

Dynamic Modeling and Simulation of Two-stage Compression Heat Pumps with Flash Economizer

Daniel Favrat, Jean-Baptiste Carré, Samuel Henchoz, Simon Gailledrat

Multistage heat pumps are one of the most efficient technologies for delivering heat at temperatures below 100°C, Thanks to their fairly high exergy efficiency. In the recent years the development of radial compressors mounted on gas bearings have unlock t ...
