Thermal Performance Analysis of Reciprocating Compressors for Refrigerator-freezers

Thermal And Fluid Dynamic Characterization Of Hermetic Reciprocating Compressors

A Framework for the Analysis of Thermal Losses in Reciprocating Compressors and Expanders

This article presents a framework that describes formally the underlying unsteady and conjugate heat transfer processes that are undergone in thermodynamic systems, along with results from its application to the characterisation of thermodynamic losses due to irreversible heat transfer during reciprocating compression and expansion processes in a gas spring. Specifically, a heat transfer model ...

Rod Loading of Reciprocating Compressors

Thermal modeling and performance analysis of a thermoacoustic refrigerator.

A heat-driven thermoacoustic refrigerator has been designed and tested. A detailed thermal model of the device is presented. Energy balances within the system are discussed using external, heat exchanger, and stack control volumes in order to clarify the relationships of work and heat fluxes below and above onset. Thermal modeling is discussed as a tool for performance analysis as well as for d...

A Method To Estimate The Performance Of Reciprocating Compressors

This paper proposes a method of evaluating the performance of reciprocating compressors. An analytical formula of the volumetric efficiency is presented. This formula, based on both theoretical and empirical approach, takes account of the most important factors, which occur during the working process of the compressor and affect the refrigeration performance. An accurate determination of the cl...
