Fuel and energy resources price surge as well as global warming pushes us to set problem of searching innovative technologies for energy transformation, to develop new technologies on the base of thermodynamic cycles with high efficiency, to use new working mediums in order to develop ecologically safe energy system, which can satisfy industrial sector alone with housing and utilities for minimum amount used. In this paper we describe Stirling refrigeration system for medium-temperature cooling. Stirling-engine embodiment characteristics are analyzed in order to derive defects, limitations as well as to propose the way of disadvantages removal. Principal advantages of Stirling refrigeration system are represented such as environmental safety, higher energy coefficient, overall detentions reducing and lower energy consumption. Construction problems and Stirling refrigeration system production with high efficiency are analyzed. Defined data let us to claim that The Medium-Temperature Stirling Refrigeration Systems use offers a bundle of benefits and opportunities for medium-temperature cooling.
