Abstract
A Stirling cycle refrigerating system has a pair of reversed Stirling cycle engines 3a and 3b, each comprising a warm head 8a and 8b of which the temperature rises as the reversed Stirling cycle engine is driven, a cold head 7a and 7b of which the temperature falls as the reversed Stirling cycle engine is driven, and a piston and a displacer that vibrate inside a cylinder along the axis thereof with an identical period and with a predetermined phase difference maintained. Inside a machine chamber 15, the pair of reversed Stirling cycle engines 3a and 3b is arranged coaxially with the axes thereof aligned with each other and with the cold heads 7a and 7b thereof facing away from each other, and the pistons or displacers of the pair of reversed Stirling cycle engines 3a and 3b are driven to vibrate in phase with each other. This Stirling cycle refrigerating system, despite being manufactured at low costs, offers cooling performance on the order of several hundred watts and produces no annoying vibration or noise when operating.
