CONTROL-COMMAND DEVICE ALLOWING THE MANAGEMENT OF HEAT TRANSFERS TO IMPROVE OR ADAPT THE GEOTHERMAL HEAT RECOVERY FROM THE SOIL IN A HEAT PUMP SYSTEM.

摘要

Control-command device allowing the management of heat transfers to improve or adapt the recovery of geothermal heat from the ground in a heat pump system.The invention is characterized by the adapted geothermal exchange, thanks to the thermal coupling of two Contiguous underground pipes, constituting a heat exchanger where the evaporator of the heat pump is included. The control of the reversal of the circulation flows makes it possible to avoid freezing of the ground, which is detrimental for the heat exchange. The invention comprises a network of two contiguous buried pipes. One carries a thermal fluid type antifreeze solution (1) the other serves as an evaporator (2) for the heat pump (3). A device (6) controlled by a temperature sensor (7) performs the operating mode reversal "parallel currents (anti-methodical) or Counter-currents (methodical)" of the exchanger formed.
