Abstract (en)
[origin: WO2011071959A2] The geothermal heat pump has a programmable logic controller (PLC) that provides real time control and monitoring of a water-to-water geothermal heat pump system to effect simultaneous heating and cooling. Directing water flow from an evaporative exchanger or a condensing exchanger achieves temperature control without the need for a conventional reversing valve. To provide system scalability, the PLC can be connected to modular units in a master/slave control configuration. Combinations of units having different refrigerant physical properties provide a "fusion" of adaptability, thereby eliminating difficulties in using carbon dioxide (C02) in home and commercial markets. Various operating refrigerant units (C02, R410a, and the like) may be combined for optimization of overall performance. Hybrid units include solar panels to preheat water. The PLC allows integration of alternative heat/cooling sources to form the hybrid units.
