FIELD: heating.
SUBSTANCE: invention deals with method of utilising geothermal energy in heat and refrigeration supply systems. The invention concept is as follows: heated geothermal well water is utilised by an absorption heat pump generator to provide for the heat pump operation and further - for additional heating of the cold water supply system tap water to have been preheated in the absorber. When the heat pump is used to provide for heat supply in colder season water is supplied into the heat pump evaporator to be therefrom discharged back into the well with the facility-heating system water heated in the condenser. When the heat pump is used to provide for heat supply in warmer season water is utilised by the consumer to be further supplied into the heat pump condenser and therefrom discharged back into the well with the refrigeration supply system water chilled in the evaporator.
EFFECT: improved cost-efficiency of heat and refrigeration supply.
