    • An apparatus connected to a refrigeration system and a geothermal system, the apparatus comprising: a first refrigerant connection connecting a compressor discharge line of a refrigerant circuit of a refrigeration system to a first side of a first heat exchanger, the first side of the first heat exchanger being couplable to the refrigerant and a second side of the first heat exchanger being couplable to ambient air, a second refrigerant connection connecting the first side of the first heat exchanger to a first side of a second heat exchanger, a second side of the second heat exchanger being couplable to a working fluid in a geothermal system, a third refrigerant connection connecting the first side of the second heat exchanger to a liquid return line of the refrigeration circuit, a first refrigerant interconnection that interconnects the first refrigerant connection with the second refrigerant connection, a second refrigerant interconnection that interconnects the second refrigerant connection with the third refrigerant connection, a third refrigerant interconnection that interconnects the first refrigerant connection with the third refrigerant connection, a first valve system for diverting the flow of refrigerant through preselected paths in the connections and interconnections, a second valve system for controlling the amount of working fluid flowing through the second side of the second heat exchanger, a fan for controlling the amount of air flow through the second side of the first heat exchanger, and a control system, connected to the first and second valve systems and the fan, for controlling for valve positions in the first and second valve systems and fan speed.

    • A refrigeration system is provided. The system comprises an evaporation region for at least partially evaporating a condensed fluid to form an evaporated fluid. A condensation region is provided for condensing the evaporated fluid to form the condensed fluid. The condensation region and the evaporation region are preferably in fluid communication. A circulation means is also provided for continuously circulating the evaporated fluid between the evaporation region and the condensation region. The circulating means are configured to circulate the evaporated fluid, while not employing a compressor, between the evaporation region and the condensation region such that flow rate of the evaporated fluid increases allowing for condensation of the evaporated fluid to occur at higher condensation region temperatures than condensation region temperatures required when the circulating means are not employed. A valve means is provided for directing the evaporated fluid through a compressor when the system is to operate in a compression mode, and for bypassing the compressor when the system operates in a thermosyphon mode.
