Abstract
A geothermal heat utilization system includes a heat source well facility, a heat source device having a refrigeration cycle including a compressor, a condenser, an expanded portion, and an evaporator, a primary refrigerant circuit that is connected to a first unit which is one of the condenser and the evaporator of the heat source device, heat exchange being able to be performed between the first unit and the well-side pipe, a secondary refrigerant circuit that is connected to a second unit which is the other of the condenser and the evaporator of the heat source device, heat exchange being able to be performed between the second unit and a load, and a mode switching unit that switches between a cold heat storage operation mode in which the primary refrigerant circuit is connected to the evaporator and the secondary refrigerant circuit is connected to the condenser and a cold heat discharge operation mode in which the primary refrigerant circuit is connected to the condenser and the secondary refrigerant circuit is connected to the evaporator.
