    摘要: A heat and cooling system having an indoor air coil subcircuit, an outdoor air coil subcircuit, a geothermal subcircuit, and a control system for selectively operating the system in air-to-air heating, air-to-air cooling, geothermal heating, air-to-air defrost (optionally) and geothermal defrost modes. The various subcircuits may be connected to one another in parallel. The heating and cooling system may include a control system that permits refrigerant to be selectively routed through any two of the heat exchangers to provide the various modes of operation. In one embodiment, the control system may generally include a circuit having a single reversing valve, a plurality of check valves, a plurality of solenoid valves and a plurality of expansion devices.
