    Abstract: A system for detecting and mitigating a refrigerant leak includes a temperature control device configured to transmit control signals to a component controller and a blower configured to circulate air. The system includes a leak mitigation controller electrically coupled to the temperature control device and the component controller. The leak mitigation controller directs incoming power to the temperature control device. The leak mitigation controller includes a sensor configured to measure a refrigerant concentration and a relay configured to selectively: (i) connect the temperature control device to the incoming power or (ii) connect the blower to the incoming power. The leak mitigation controller is configured to measure the refrigerant concentration with the sensor and, in response to the measured refrigerant concentration exceeding a threshold, actuate the relay to connect the blower to the incoming power.

    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 refrigerant leak sensor includes: a first refrigerant sensor element configured to, when powered: measure a first amount of the refrigerant present in air; and generate a first output based on the first amount; a second refrigerant sensor element configured to, when powered: measure a second amount of the refrigerant present in air; and generate a second output based on the second amount; a first selection module configured to: during a first period, apply power the first refrigerant sensor element and not apply power to the second refrigerant sensor element; and during a second period after the first period, apply power to the second refrigerant sensor element and not apply power to the first refrigerant sensor element.

    Abstract: A heat-pump system may include a compressor, an outdoor heating exchanger, an indoor heat exchanger, an expansion device, and a supplemental heater. The outdoor heat exchanger may be in fluid communication with the compressor. The indoor heat exchanger may be in fluid communication with the compressor. The expansion device may be in fluid communication with the indoor and outdoor heat exchangers. The supplemental heater may include a burner and a working-fluid conduit. The burner may be configured to burn a fuel and heat the working-fluid conduit. When the heat-pump system is operating in a heating mode, the indoor heat exchanger may receive working fluid from the working-fluid conduit such that the working fluid flows from an outlet of the working-fluid conduit to an inlet of the indoor heat exchanger.

    Abstract: A mitigation verification system includes: a control module configured to selectively transition a mitigation device of a refrigeration system of a building from a first state to a second state; and a verification module configured to verify and generate an indicator of whether the mitigation device of the refrigeration system transitioned from the first state to the second state based on a change in a parameter of the refrigeration system over a period in response to the transition by the control module.

    Abstract: A system for charging an outdoor unit with refrigerant includes a sensor configured to measure a refrigerant concentration and a user device configured to receive the measured refrigerant concentration. The system includes that the user device is configured to, in response to the measured refrigerant concentration exceeding a threshold, generate and display an alert on a user interface of the user device indicating the measured refrigerant concentration exceeds the threshold.
