Résumé

In 2002, an unconventionally designed heat source with utilization of geothermal water with the temperature of 30 °C supplied from a drill well was put in operation in the town Decín in the Czech Republic as a replacement of the existing heating system of the town supplied by heat from non-ecological local boiler houses. The heat production in the source is based on the cooperation of ammonia heat pumps, cogeneration gas engines and gas boilers. The main source of energy is the natural gas. Electric energy required for the operation of the heat source is produced by gas engines. The hot water thermal storage system forming also a part of the heat source provides for equalizing the peak consumption of heat supplies during summer and transition periods. During the winter period the gas boilers join in the heat production and the utilization of the hot water thermal storage system stops working. The design solution includes also the geothermal water treatment to drinking water with linking-up supply to town water main. The heat output supplied to the heating system network represents 2.5 MW to heat water temperature from 55 to 80 °C during the summer period and 39 MW to heat water temperature from 65 to 110 °C during the winter period. The paper records the basic data of the source technical solution including the choice of heat pumps and economic and ecological aspects.
