    Abstract: A compressor may include first and second scrolls, and an axial biasing chamber. Spiral wraps of the scrolls mesh with each other and form compression pockets including a suction-pressure compression pocket, a discharge-pressure compression pocket, and intermediate-pressure compression pockets. The axial biasing chamber may be disposed axially between the second end plate and a component. Working fluid disposed within the axial biasing chamber may axially bias the second scroll toward the first scroll. The second end plate includes outer and inner ports. The outer port is disposed radially outward relative to the inner port. The outer port may be open to a first one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber. The inner port may be open to a second one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber.

    Abstract: An IAQ sensor module includes: a sensor configured to measure an amount of an item in air, the item being one of particulate matter, volatile organic compounds, and carbon dioxide; a minimum module configured to selectively store the amount of the item as a minimum value of the amount when a mitigation device has been on for at least a predetermined period, the mitigation device being configured to decrease the amount of the item in the air when on; a storing module configured to selectively store the minimum value as an initial minimum value; an offset module configured to determine a drift offset for the sensor based on a difference between the minimum value and the initial minimum value; and an adjustment module configured to determine an adjusted amount of the item in the air at the IAQ sensor module based on the amount and the drift offset.

    Abstract: An indoor air quality (IAQ) system for a building includes an IAQ sensor that is located within the building and that is configured to measure an IAQ parameter, the IAQ parameter being one of: a relative humidity (RH) of air; an amount of particulate of at least a predetermined size present in air; an amount of volatile organic compounds (VOCs) present in air; and an amount of carbon dioxide present in air. A mitigation module is configured to: selectively turn on a mitigation device based on a comparison of the IAQ parameter with a first threshold; and selectively turn off the mitigation device based on a comparison of the IAQ parameter with a second threshold. A thresholds module is configured to: set the first and second thresholds to predetermined default values; and selectively adjust at least one of the first and second thresholds.

    Abstract: A condition identification module is configured to, based on output from the at least one of a microphone and a camera, indicate an occurrence of a user having a physical condition. A correlation module is configured to, based on the occurrence of the user having the physical condition and at least one of a temperature of air, a relative humidity of air, an amount of particulate of at least a predetermined size present in air, an amount of VOCs present in air, and an amount of carbon dioxide present in air, selectively identify the presence of a correlation between the occurrence of the user having the physical condition and the at least one of the temperature, the RH, the amount of particulate, the amount of VOCs, and the amount of carbon dioxide.

    Abstract: A climate-control system includes a working fluid circuit and a storage tank. The working fluid circuit has a first compressor, a first heat exchanger, a second heat exchanger, a flash tank, and a third heat exchanger. The first heat exchanger receives working fluid discharged from the first compressor. The flash tank is disposed downstream the first heat exchanger and includes an inlet and first and second outlets. The first outlet provides working fluid to the third heat exchanger disposed between the flash tank and the first compressor. The second outlet provides working fluid to the first compressor. The storage tank contains phase-change material that is thermally coupled with the second heat exchanger of the working fluid circuit.

    Abstract: A climate control system includes an electrochemical device in fluid communication with at least one fluid conduit that also includes a first heat exchanger, an expansion device, and a pump, but may be free of any condensers. A working fluid is circulated in the fluid conduit that has a composition that undergoes a reversible hydrogenation and dehydrogenation reaction when it passes through the electrochemical device when a potential is applied thereto. The climate control system includes a heat rejection system in the form of a recirculation loop having a second heat exchanger configured to cool a portion of the working fluid exiting the electrochemical device and a recirculation pump that circulates the portion of the working fluid exiting the electrochemical device through the second heat exchanger and back to an inlet of the electrochemical device. Methods for rejecting heat from an electrochemical climate control system are also provided.
