Abstract
A refrigeration system to provide cooling during refrigerant leak is disclosed. The system detects a refrigerant leak by detecting that a refrigerant concentration is more than a threshold concentration on at least two occasions. The system executes a mitigation plan until the concentration of refrigerant is less than the threshold concentration. The system determines if it is operated in a safe mode, where in the safe mode, a blower of the system is set to operate continuously. When the system is in the safe mode, the system determines a number of times where the concentration of refrigerant exceeded the threshold concentration. In response to determining that the number of times where the concentration of refrigerant exceeded the threshold concentration is more than the threshold value, the system operate the HVAC system in the safe mode and communicate a first alert message.
