Abstract
The present disclosure relates to a heating, ventilating, and air conditioning (HVAC) system that includes a refrigerant circuit and a sensor configured to measure a refrigerant concentration external to the refrigeration circuit. The HVAC system also includes a controller that is communicatively coupled to the sensor and to an economizer. The controller is configured to control a flow of environmental air into the HVAC system. The controller is further configured to increase a ratio of the flow of environmental air relative to a flow of return air from a conditioned interior space of a building when the sensor measures the refrigerant concentration above a predetermined threshold concentration.
