    Abstract: A refrigerant measurement adjustment system includes: a refrigerant sensor for a building and configured to measure an amount of refrigerant present in air outside of a refrigeration system of the building; and an adjustment module configured to: adjust the amount of refrigerant measured based on an adjustment to produce an adjusted amount; and determine the adjustment based on at least one of: an air temperature; an air pressure; a relative humidity of air; a mode of operation of the refrigeration system; a change in the measurements of the refrigerant sensor over time; and whether a blower that blows air across a heat exchanger of the refrigeration system located within the building is on.

    Abstract: A control system for a mitigation device includes a processor and a computer-readable medium that includes instructions executable by the processor. The instructions include monitoring a first measured particulate matter (PM) level of a conditioned space. The first measured PM level includes PM having a first range of sizes. The instructions further include monitoring a second measured PM level of the conditioned space. The second measured PM level includes PM having a second range of sizes. The first and second ranges are different but overlapping. The instructions also include asserting, in response to the first measured PM level being greater than a first predetermined threshold, an activation signal. The activation signal forces operation of a fan of the mitigation device. The instructions include asserting, in response to the second measured PM level being greater than a predetermined percentage of the first measured PM level, the activation signal.

    Abstract: A climate-control system may include a compressor, a thermal storage device, an outdoor heat exchanger, an indoor heat exchanger, a first expansion device, and a second expansion device. The compressor may include an intermediate-pressure inlet, an intermediate-pressure outlet, a discharge outlet, a suction-pressure pocket, and a plurality of compression pockets. The thermal storage device may include a conduit and a phase-change material surrounding the conduit. The first expansion valve, the second expansion valve, the outdoor heat exchanger, the indoor heat exchanger, and the thermal storage device may be in fluid communication with the compressor. The climate-control system is operable in a charging mode and a discharging mode, and is operable in a cooling mode and a heating mode. The thermal storage device may be configured to absorb heat from a working fluid or to transfer heat to the working fluid.

    Abstract: An example refrigeration system includes an indoor fluid loop, an outdoor fluid loop, and a heat exchanger assembly. The indoor fluid loop circulates a first working fluid. The outdoor fluid loop circulates a second working fluid that is different from the first working fluid and is separated from the indoor fluid loop by a wall of a structure. The heat exchanger assembly is mounted within the wall of the structure. The heat exchanger assembly includes a heat exchanger and a housing, where the heat exchanger is disposed within an internal space defined by the housing. The housing supports the heat exchanger within the internal space and is mounted to a structure of the wall.

    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 heating, ventilation, and air conditioning (HVAC) control system generates a request to replace a first air filter installed in an air handler of an HVAC system with a second air filter. The second air filter has a particulate matter removal efficiency rating that is greater than a particulate matter removal efficiency rating of the first filter. The system delays for a predetermined period of time and then obtains (i) a first temperature of air downstream of the air handler and (ii) a second temperature of air upstream of the air handler. The system then calculates a temperature difference between the f temperatures and determines whether the temperature difference is within an acceptable range. In response to the temperature difference being within the acceptable range, the system (i) operates the HVAC system using the second air filter and (ii) generates an alert indicating compatibility of the second air filter.
