Abstract: First and second IAQ sensors are located within a building and are configured to measure first and second IAQ parameters, respectively, the first and second IAQ parameter being the same one of: relative humidity; amount of particulate; amount of volatile organic compounds; and amount of carbon dioxide. A mitigation device is separate from an HVAC system and includes a control module configured to turn the mitigation device on and off based on the first IAQ parameter, the second IAQ parameter, and whether the HVAC system is on or off. A mitigation module is configured to selectively turn the HVAC system on and off based on the second IAQ parameter, the first IAQ parameter, and whether the HVAC system is on or off.

Abstract: A system and method for a compressor includes a compressor connected to a condenser, a discharge line temperature sensor that outputs a discharge line temperature signal corresponding to a discharge line temperature of refrigerant leaving the compressor, and a control module connected to the discharge line temperature sensor. The control module determines a saturated condenser temperature, calculates a discharge superheat temperature based on the saturated condenser temperature and the discharge line temperature, and monitors a flood back condition of the compressor by comparing the discharge superheat temperature with a predetermined threshold. The control module increases a speed of the compressor when the discharge superheat temperature is less than or equal to the predetermined threshold.

Abstract: A working-fluid circuit may include an indoor heat exchanger, a variable-capacity compressor and a control module. The variable-capacity compressor pumps working fluid through the indoor heat exchanger. The control module may control the compressor and operate the compressor in one of a first capacity mode and a second capacity mode based on a demand signal, outdoor-air-temperature data and a compressor runtime.

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 system includes a compressor and a controller. The controller operates the compressor in a flooded-start control mode. The flooded start control mode includes operating the compressor according to at least one cycle including a first time period during which the compressor is on, followed by a second time period during which the compressor is off. The controller determines at least one of the first time period, the second time period, and a number of cycles for the flooded-start control mode. At least one of the first time period, the second time period, and the number of cycles is based on received asset data corresponding to at least one of a type and a characteristic of at least one component of the refrigeration system. The controller operates the compressor in the flooded-start control mode after determining the first time period, the second time period, and the number of cycles.

Abstract: A system includes a variable-capacity compressor operable at a first capacity and at a second capacity that is higher than the first capacity and an outdoor-air-temperature sensor. A control module receives a demand signal from a thermostat and operates the variable-capacity compressor in a first mode when communication with the outdoor-air-temperature sensor has not been interrupted and in a fault mode when communication with the outdoor-air-temperature sensor has been interrupted. In the first mode, the control module switches the variable-capacity compressor between the first capacity and the second capacity based on the demand signal and the outdoor-air-temperature data. In the fault mode, the control module operates the variable-capacity compressor by operating the variable-capacity compressor at at least one of the first capacity and the second capacity based on the demand signal.
