AN EXPERIMENTAL STUDY OF THE AMMONIA HERMETIC SMALL REFRIGERATION MACHINE.

The article focuses on the study of the design parameters of small refrigerating machines. This article shows practical studies of the dependence of the energy parameters of the refrigerating machine on its design features.In particular, the dependence of the coefficient of performance upon the superheating of steam at the suction in the compressor was studied, and preventing method of such overheating for small refrigerating machines was proposed. At the second stage the possibility of using a regenerative heat exchanger in an ammonia refrigerating machine was examined. The advantages of its use are shown. In general, the possibility of increasing the refrigeration efficiency by changing design parameters of the refrigerating machine is shown.
