COMBINED NATURAL GAS AND SOLAR TECHNOLOGIES FOR HEATING AND COOLING IN THE CITY OF NIS IN SERBIA

The use of conventional systems for heat and electricity production in Nis and Serbia means a constant waste of energy, and money. This problem is present in both industrial and public sector. Using conventional systems, means not only low-energy efficient systems, and technologies, but also using very 'dirty'technologies, which cause heavy environment pollution. The lack of electricity in our country, and region is also present. The gas pipeline in Ni was finished not long ago, and second gas pipeline is about to be made in the next couple of years. This opens a door for implementing new technologies and the use of new methods for production of heat and electricity, while preserving our environment. This paper reports discussion of this technology with management of public institutions, which use both heat and electricity.
