A method and system for optimizing the operation of a geo-exchange system, by generating predictive models pertaining to energy demand and energy capacity for a particular building or district, based on data from sensors associated with components of a district geo-exchange system, historical and real-time operational data associated with district modules, including weather forecast data and current weather conditions.

An air conditioning system including a condenser system and a closed-loop air-to-water system. The condenser system includes a compressor which pressurizes refrigerant and distributes the pressurized refrigerant to at least one condenser coil, which climatizes water; and a fan which exhausts heat from the pressurized refrigerant. The closed-loop air-to-water system includes a climatized liquid tank, which receives climatized water from the at least one condenser coil; and an air handler disposed within a building, the air handler having a climatized liquid coil. The air handler is disposed to receive air from inside the building; transfer thermal energy from the climatized liquid coil to ambient air, creating climatized air; and distribute the climatized air to at least a portion of the building. The climatized water may be distributed to a recycled liquid tank, which may redistribute the climatized water to the climatized liquid tank, forming a closed-loop air-to-water system.

Systems and methods for controlling temperature and humidity within a space in a building. Outdoor air and return air from the space are passed through particular equipment in a particular order. Equipment includes a secondary direct-expansion refrigeration circuit, a recovery wheel, a primary cooling coil, secondary circuit evaporator and condenser coils, and a dehumidification wheel. Various embodiments include multiple zones, chilled beams, and a dedicated outdoor air supply (DOAS) subsystem delivering dehumidified air to active chilled beams. In various embodiments, supply air passes first through the recovery wheel, then through the primary cooling coil, then through the dehumidification wheel, and then to the space. Further, in some embodiments, exhaust air passes through the dehumidification wheel and then through the recovery wheel. Pump modules may supply chilled beams and control their temperature to avoid condensation. A chiller may supply cooling water to both the primary cooling coil and the pump modules.

A geothermal cooling system comprises an open-air structure and a closed, geothermal loop configured to cool an environment in which the open-air structure is located.
