The types of Autonomous stationary energy-cooling systems designed for complete isolation of special objects operating without connection with the atmosphere are Considered. A technical solution is proposed that allows increasing the efficiency of the energy-cooling system, reducing the consumption of process water due to its partial recirculation for cooling the engine of an Autonomous power plant, as well as increasing the period of complete isolation of the object.

The authors of the article developed an autonomous energy supply system for remote military facilities and settlements using liquefied natural gas. A characteristic feature of the developed system is a simplified constructive design of cryogenic equipment for liquefied natural gas, increased reliability and service efficiency of an autonomous energy supply system, as well as the possibility of independent operation of a gas engine and a boiler station from each other.
