  • Patent number: 11067039
    Abstract: A method and system for condensing water for injection into an internal combustion engine to increase the engine's fuel economy and performance while reducing emissions. A volume of ambient air is drawn through an intake valve into a sealable chamber. The intake valve is closed and the ambient air compressed within the sealed sealable chamber and thereafter vented through an exit valve to be contained in a cooling section. The cooling section comprises a port and a cooling device. The cooling device, which in one embodiment comprises a refrigeration unit, cools the ambient air contained within the cooling channel to condense water vapor present in the ambient air into liquid water. The liquid water is drained from the cooling channel through the port and collected in a reservoir. Liquid water from the reservoir is then injected into at least one combustion chamber of the internal combustion engine.

  • Patent number: 11032978
    Abstract: Disclosed is a climate control system for use with an indoor plant growing environment. The system includes an air supply system and a refrigeration system. The refrigeration system utilizes a reheat coil in parallel with a condenser coil. In the airflow path of the air supply system the reheat coil is positioned downstream of the cooling coil. The method of operating the climate control system relies upon the input of set point values for enthalpy, dry bulb temperature and dew points into a controller. The controller receives data from sensors within the plant growing environment and uses this data to manage the operation of a three-way valve, supply fan speed, and compressor speed in order to maintain the indoor plant growing environment within an accepted range of each of the three set points.

    Abstract: An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

  • Patent number: 9752788
    Abstract: In an adsorption operation in which the adsorption agent adsorbs water, air in a vehicle compartment flows into an adsorption agent module after being cooled by passing around a heat sink. On the other hand, in a desorption operation in which the water is desorbed from the adsorption agent, the air in the vehicle compartment flows into the adsorption agent module to be humidified without being heated or cooled, and humidified air is cooled by passing around the heat sink and blown into the vehicle compartment. Accordingly, a temperature of the humidified air can be prevented from increasing unnecessarily by a simple configuration with which the air in the vehicle compartment is cooled in the heat sink.
