NOVELTY - An energy management system comprises central control unit, and two cabinets which are separated for isolation of batteries. The central control unit comprises a set of controls, measurement instruments, sensors, touch screen, and tele-management system. The cabinets are made of metal plates and heat insulating walls, thus ensuring thermal isolation. The cabinets are located outside and inside of the shelter for the maintenance of appropriate temperature conditions. Direct-current voltage Peltier thermoelectric elements are installed to reduce the temperature.    USE - Energy management system for shelters which house telecommunications equipment used to receive and emit telecommunications signals for the operation of radio aids and radio beacons used in aircraft navigation and military applications and for isolated scientific stations, such as meteorological stations and installations using photovoltaic arrays.    ADVANTAGE - The energy management system has the ability to manage the operation of generators to satisfy the telecommunications and cooling loads which include operating conditions e.g. reduction of fuel consumption, reduction of generator operating time and improvement of efficiency; has the ability to store electric energy in the batteries due to the excess power of the generators to satisfy the peak load during operation of air-conditioning units; and provides additional energy savings deriving from modulation of temperature in the telecommunications equipment compartment. The temperature modulation is optimized for the cases where air-conditioning devices equipped with free-cooling system with fresh air is used, since the telecommunications equipment compartment is conditioned to a higher temperature compared to battery compartment. Further, the energy management system can cooperate with any type of commercial air-conditioning apparatus.    DETAILED DESCRIPTION - An energy management system comprises central control unit comprising a set of controls, measurement instruments, sensors, touch screen and tele-management system; and two cabinets which are separated for isolation of the batteries and are made of metal plates and heat insulating walls, thus ensuring thermal isolation. The tele-management system monitors and records the operational parameters of the shelter and makes decisions to activate the corresponding automatic controls relating to the energy management and the operation of generators needed for the electric supply of the shelter by monitoring indoor and outdoor temperature data and storing the excess power generated by over-dimensioned generators. The cabinets are located outside and inside of the shelter for the maintenance of appropriate temperature conditions. Direct-current voltage Peltier thermoelectric elements are installed to reduce the temperature.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of the interaction of the energy management system with electro-mechanical equipment of the shelter.
