The analysis of the possibilities to use the effect of night radiation (ENR) for additional heat removal from the elements of the cooling system is carried out. The energy prospects of ENR technology for autonomous cooling systems are shown mainly in rural and peasant farms remote from electric energy sources. To increase the energy efficiency of autonomous cooling systems, it is proposed to use absorption water-ammonia refrigeration machines (WARM) and vapor compression refrigeration machines. It is proposed to use the thermal energy of solar radiation for the WARM operation.
