This paper presents simple and thermodynamically realistic models of two types of
compressors widely used in domestic heat pumps (reciprocating and scroll compressors) …

Heat pumps and refrigerators are two systems with different usage, but same working
principles. Generally, HPs work in steady state condition and specific thermodynamic cycle …

In the present study, a zero-dimensional numerical method is developed based upon the
crank angle to investigate reciprocating natural gas compressor with valve faults. This model …

Reciprocating multiphase pump is the key equipment for the oil-gas transport technology in
the petroleum industry. The opening and closing motions of suction and discharge valves …

This article investigates how hydrofluorocarbon (HFC) refrigerant affects compressor
operating conditions and system performance using experimental testing under different …

A miniature multi-stage compressor (MMSC) with an integrated inter-stage cooler has been
proposed. This study aims to evaluate the efficiency of each stage of the MMSC under …

A comprehensive model of a linear compressor for electronics cooling was previously
presented by Bradshaw et al.(2011). The current study expands upon this work by first …

Among the various ways to simulate compressor behaviour, using efficiency definitions such
as volumetric, isentropic or effective is relatively easy to perform and rapid when dynamic …

In today's refrigeration and air-conditioning industries, numerical simulation has been widely
used for the design and optimization of advanced products. Cost saving and to shorten …

ABSTRACT A self actuated valve is commonly used in the intake manifold of small
hermetically sealed reciprocating compressors. During the gas exchange process the valve …
