Abstract:
The technological scheme of "heat pump-ground vertical heat exchanger" facility of ground energy application for the heating and ventilation of a residential district is described. It provides heating and hot water supply due to low- temperature solar and ground thermal potential as well as enables indoor air cooling and hot water installations in summer season via thermal-compressor heat pump. A part of condensation quantity of refrigerant is used in this case to obtain useful heat, and the other part, together with energy gained via solar collector, is used to recover the thermal balance of layers adjacent to the ground thermal exchanger. The facility calculation indicators are given, and its energetic-technical indicators are compared with the indices of gas boiler-thermal-compressor refrigerating machine facilities.
Keywords:district heating and cooling supply, non-traditional sources of heat and cold, application of ground heat potential.
