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 system and method for flooded start control of a compressor for a refrigeration system are provided. A sensor generates sensed data corresponding to a condition of the refrigeration system. A control module is configured to operate the compressor in a flooded-start control mode including operating the compressor according to a cycle with a first time period during which the compressor is on and a second time period during which the compressor is off. The control module operates the compressor in an initial time period, without using the flooded-start control mode, with liquid refrigerant present in the compressor and monitors the sensed data from the sensor. The control module operates the compressor in the flooded start control mode after determining the first time period, the second time period, or a number of cycles, based on the sensed data monitored during the initial time period.

Abstract: System and methods are provided and include a compressor operable in a refrigeration circuit, a first sensor detecting high-side data indicative of a high-side operating condition of a high-pressure side of the refrigeration circuit, a second sensor detecting low-side data indicative of a low-side operating condition of a low-pressure side of the refrigeration circuit, and processing circuitry. The processing circuitry receives the high-side data and the low-side data, determines a high-side fault, a low-side fault, a severe high-side fault, or a severe low-side fault based on the high-side data and the low-side data, operates the compressor in a limp-along mode by restricting power to the compressor or reducing a capacity of the compressor in response to determining at least one of the high-side fault and the low-side fault, and shuts down the compressor in response to determining at least one of the severe high-side fault and the severe low-side fault.

Abstract: A system and method for calculating parameters for a refrigeration system having a variable speed compressor is provided. A compressor is connected to a condenser and an evaporator. An evaporator sensor outputs an evaporator signal corresponding to at least one of an evaporator pressure and an evaporator temperature. An inverter drive modulates electric power delivered to the compressor to modulate a speed of the compressor. A control module is connected to the inverter drive that receives the evaporator signal. The control module monitors electrical power data and compressor speed data from the inverter drive and calculates at least one of a condenser temperature and a condenser pressure based on the evaporator signal, the electrical power data, and the compressor speed data.
