โœฆ Synopsis


A parametric analysis was carried out in order to examine the effect on the cooling capacities of the two stages of a commercial pneumatically driven cryorefrigerator, caused by a variation of several design parameters of the cryorefrigerator. The analysis was performed by using a previously developed algorithm that modelled the dynamic characteristics of a pneumatically driven Gifford -McMahon cryorefrigerator, in the form of first-order partial differential equations. In addition, a state of the art optimization design approach is presented, which maximizes the capacities of the two stages by calculating the optimal values of the critical design parameters that minimize an appropriate objective function.

Exergy or the available work energy function is a useful concept for analysing a Gifford-McMahon cycle. By definition, exergy of a state 1 is the maximum work that would be obtained in bringing the state to the dead state or ambient state for a heat engine. For a refrigerator, exergy is the minimum

The motional heat loss of a Gifford-McMahon (G-M) cryorefrigerator was calculated by a finite difference formulation. The two-dimensional axisymmetric finite difference model consisted of a set of equations describing the transient heat transfer in the radial and axial directions from the displacer

A heat balance analysis of single stage Gifford-McMahon cycle cryorefrigerator is presented. Ideal refrigeration, actual refrigeration, net refrigeration and the various losses are tabulated. It is observed that pressure-volume losses account for a major fraction of the total losses.
