Abstract
The article investigates optimum parameters of regenerator disk chequers for gas refrigerating machine. The parameters of disk chequer geometric characteristics providing their best efficency are selected. The influence of grooved belt parameters on specific surface of the chequer, as well as its relative void and equivalent diameter is evaluated. The influence of disk chequer geometric characteristics on the design parameters of regenerators is analyzed, the most important characteristics being the length of the chequer and its hydraulic resistance. The evaluation of the disk chequers with grooved belts of different geometry is aimed at providing the most effective carbon dioxide freezing out in turbo-expander of gas refrigerating machine.

Keywords: disk chequer, geometric characteristics, specific surface of chequer, relative void, hydraulic resistance, gas refrigerating machine, carbon dioxide freezing out.
