Abstract
A multi-source ground-to-air heat transfer system is configured to store thermal energy during a cooling/dehumidifcation mode of operation for future use during a heating mode of operation. The multi-source ground-to-air heat transfer system utilizes a ground loop that is configured under an enclosure, such as a greenhouse, and is in thermal communication with a thermal reservoir medium to conduct and store heat. A thermal exchange fluid is pumped through the ground loop and ground heat exchanger and may receive heat from a condenser during a cooling/dehumidification mode of operation and may liberate heat to the evaporator during a heating mode. The enclosure air may receive heat from the heat pump during a heating mode and may liberate heat to the evaporator during a cooling/dehumidification mode. The heat exchange system may employ a heat pump having a reversing valve to change the mode of operation.
