The prospects of using the “night radiation effect” (NRE) for autonomous cooling systems are shown in the paper. An algorithm has been developed to search for the minimum temperature of a heating source of an absorption water-ammonia refrigeration machine (AWRM). It is shown that in AWRM there are modes with maximum energy efficiency with an appropriate combination of the composition of the working fluid and the temperatures of the heating source. The advantages of vapor compression systems (VCS) at low ambient temperatures are shown. The schemes of milk cooling systems with VCS and AWRM and using the NRE technology are proposed.
