Abstract: Solar thermal units and methods of operating solar thermal units for the conversion of solar insolation to thermal energy are provided. In some examples, solar thermal units have an inlet, and a split flow of heat absorbing fluid to either side of the solar thermal unit, along a first fluid flow path and a second fluid flow path. Optionally, one or more photovoltaic panels can be provided as part of the solar thermal unit, which may convert solar insolation to electric power that may be used by a system connected to the solar thermal unit.

Abstract: A controller can be configured to control a system for extracting liquid water from air comprising a thermal unit, a primary desiccant wheel, and a regeneration fluid path. The controller can comprise a sensor, a motor, and a microcontroller coupled to the sensor and the motor. The microcontroller can be configured to determine a water extraction efficiency based on at least one signal received from the sensor, and also can be configured to maximize the water extraction efficiency by adjusting a speed of the motor in response to the determined water extraction efficiency.

Abstract: This disclosure relates to techniques for producing liquid water from ambient air. In certain embodiments, a system includes a regeneration fluid pathway configured to receive a regeneration fluid and a thermal unit configured to heat the regeneration fluid. The system can further include a continuous desiccant unit that comprises an adsorption zone and a desorption zone, as well as a batch desiccant unit that includes a regeneration inlet and a batch desiccant housing. The batch desiccant housing can include a batch desiccant inlet configured to input the ambient air, a batch desiccant outlet configured to output a batch output fluid, and a batch desiccant material. A condenser unit can be configured to produce liquid water from the regeneration fluid, and the system can maximize a water production rate of the condenser unit based on an amount of heat carried by the regeneration fluid.

Abstract: This disclosure includes systems and methods for extracting water vapor from atmospheric air and, more particularly, but not by way of limitation, systems and methods for optimizing liquid water production from air, in some instances, taking into account diurnal variations. The systems comprise an adsorption zone and a desorption zone, an actuator to move a desiccant between the adsorption zone and the desorption zone. The liquid water production is optimized based, at least in part, on measurements of one or more of: an ambient air temperature, ambient air relative humidity, and a level of solar insolation.
