Today’s state of use of the sun, wind, thermal water power in Georgia and prospects for their development are analyzed. It is demonstrated that in case of extensive use of renewable, non-conventional energy resources, saving up to 15-20 percent of heat-power resources consumed in the country will be achieved. The conducted research suggests that one of the promising trends of the Georgian heat-power complex is energy saving and large-scale implementation of energy-saving technologies in the manufacturing enterprises of various branches of national economy.

There are significant losses of thermal energy in the food industry enterprises due to the irrational organization of energy production, which can be reduced through various measures, including by using of energy-saving heat pump installations. In the production of beer, as a result of the use of heat pump installations, in case of maximum utilization of secondary energy resources, it is possible to reduce expanses by about 25-30%, which will significantly reduce the cost of produced products. The research presented in the report shows that there are significant losses of thermal energy in beer production, the reduction of which will be effective by using energy-saving heat pump installations.

Prospects for the use of energy-saving complex systems of geothermal heat - and cold supply for different sectors of a national economy of Imereti region are offered and developed. It is shown, that in the long term the thermal potential of geothermal waters of Imereti region can be used for a heat supply of agriculture objects, industrial enterprises and settlements.

Nowadays in industry and enterprises of agricultural products processing rldusty low temperature (≈l00"C) heat processes for heat energy supply are mainly used less economy boilers or fire fumaces where expensive organic liquid and gas firel is used. rlrterori choosing new, economically more effective methods of getting heat energy is the essential scientihc and technical probleri for development of the country energetics.'Besides,-market economy mill present severer demands to afoiesaid branches of economy in future' The main demands will be: to inculcate new technologies raising quality ofproduction, reduce losses and cost price, long-term storage ofproducts and so on' But realization of everything aforesaid will be impossible without artificial cold i.e. without using refrigerating engineering

In the report the potential qspeets ofnonconventional, renewed non-standard power resources of the resort-recreational area of the Black Sea coast development of Georgia, and in partieular the site of Batumi-Anaklia, is currently estimated

Possible scales of use of a wind power in Georgia are analyzed. Depending on speed of wind and itsduration, it is possible to allocate five zones of territories in Georgia. Specific power capacities and speciJic annual developments of the electric power are defined. Technical and economic indicators of primary obiecti oJ'a wind-driven power station are obtained and scales af use of wind energt for 15-20 years with possible devilopment of the electric pwer of 5-7 billion rcBm in a year are estimated.

It is noted that basic methods, which can be used in metal manufacture for studying carbonaceous regenerating processes, are investigated. On the basis of that, a volumetric method for studying kinetics of the charges recovery, having an advantage over the considered methods, is chosen. The basic constituent of the accepted automated system is a volumeter. It includes also an electric furnace and a computer, and is supplied with elements of the temperature stabilization and control. The functional scheme of the device is given, and its work is described. With the help of the developed system the possibility for defining the value of metallurgical ore is created
