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.
