Efficient Gas and Renewable Sources Utilization - Gas Consumption Curve

Standard gas boilers and kettles with 92% efficiency degree (according to Hd) can be further installed according to EU directives. By construction of the condensation devices with 110% efficiency degree, the improvement is achieved, but also the possibility for heating and cooling energy utilization. Side by side, starts production of cogeneration and micro-cogeneration facilities for simultaneous generation of electricity and heat with 95% efficiency degree. After cooling module installation the three cogeneration facility is constructed. Next step to efficiency improvement is heat and gas pumps construction (compression/absorption process) with heating efficiency of 145%. By upgrading the mentioned devices with solar panels (photovoltaic module and solar thermal collector) the efficiency degree will be increased for 10 to 15%. All mentioned devices have high efficiency degree, but also a certain environmental impact. Today, in commercial use is micro cogeneration called fuel cell with no environmental impact. The paper deals with possible use of mentioned facilities and with their impact to levelling the gas consumption curve of heating, cooling and electric energy for various meteorological regions.
