TEPLATOR – District Cooling SolutionElectric Driven Cooling

Systems

❖Thermal energy from burning the fuel is converted to electricity in the power plants.

❖The electricity is transmitted through HV/MV/LV grids to the cooling plants or to the consumers.

❖High investments for the expansion of power grid will be necessary due to rapid growth of cooling demand.

❖Pollution emissions will be increased rapidly.
