Description
The project proposal includes construction of a geothermal heat pump installation for heating, cooling and domestic hot water supply in the building of the kindergarten "Edelweiss", located at Velingrad Municipality, Velingrad, 4 Dobri Chintulov Str. The internal modules of the system / water-to-water heat pumps / will be located in the existing boiler room. External circle: it consists of vertical drills, in each of which a geothermal set is installed and subsequent injection of the necessary materials. The system will provide energy transfer between the ground and the indoor units of the heat pump system. Water-to-water heat pump units. Internal circuit: the hot or cold water received from the heat pump units enters a buffer vessel from which it will go to the heating / cooling pipe system through a circulation pump. It is planned to supply a new boiler for domestic hot water supply. A central water pump heating installation is provided - a closed system. The premises will be heated and cooled by fan convectors. In order to ensure energy monitoring, means for measuring and controlling the heat consumption will be installed.
