Modeling of scroll compressors – Improvements
International Journal of Refrigeration, 2010 Abstract This paper presents an improvement of the scroll compressors model previously published by Duprez et al. (2007) . This improved model allows the calculation of refrigerant mass flow rate, power consumption and heat flow rate that would be released at the condenser of a heat pump equipped with the compressor, from the knowledge of operating ...

Modelling of reciprocating and scroll compressors
International Journal of Refrigeration, 2007 Abstract This paper presents simple and thermodynamically realistic models of two types of compressors widely used in domestic heat pumps (reciprocating and scroll compressors). These models calculate the mass flow rate of refrigerant and the power consumption from the knowledge of operating conditions and parameters.
