  • Patent number: 12516839
    Abstract: An air conditioning unit includes a housing, a partition disposed in the housing, a refrigerant circuit, a blower, an air valve, and a refrigerant leak detection system configured to detect a refrigerant leak within the air conditioning unit. The housing includes a first compartment and a second compartment, and the partition separates the first compartment and the second compartment. The refrigerant circuit disposed in the first compartment. The air valve extending through the partition or through the housing to the second compartment. The air valve configured to open in response to the refrigerant leak detection system detecting the refrigerant leak. A method of ventilating an air conditioning unit includes detecting, via a refrigerant leak detection system, for a refrigerant leak within the air conditioning unit, and in response to detecting the refrigerant leak, opening an air valve.

  • Patent number: 12504190
    Abstract: Methods and systems for an air conditioning unit is provided. The air conditioning unit includes a housing having a first compartment and a second compartment separated from the first compartment by a partition disposed in the housing, the housing including an air inlet and an air outlet. A refrigerant circuit includes a compressor disposed in the first compartment. An air flow path extends through the second compartment. The air flow path is arranged to route air flow from the air inlet to the air outlet, and a blower is disposed in the air flow path. A refrigerant leak detection system is configured to detect a refrigerant leak within the housing. An inducer is disposed in the housing. The inducer is configured to move air from the first compartment into the air flow path upon detection of the refrigerant leak by the refrigerant leak detection system.
