  • Publication number: 20230109334
    Abstract: A condenser charge module is configured to: determine a first amount of refrigerant in each condenser of one or more condensers of a refrigeration system; determine a total condenser amount of refrigerant based on the one or more first amounts. An evaporator charge module is configured to: determine a second amount of refrigerant in each evaporator of two or more evaporators of the refrigeration system; and determine a total evaporator amount of refrigerant based on the two or more second amounts. A line charge module is configured to: determine a third amount of refrigerant in each refrigerant line of multiple refrigerant lines of the refrigeration system; and determine a total line amount of refrigerant based on the multiple third amounts. A total module is configured to determine a total amount of refrigerant in the refrigeration system based on the total condenser, the total evaporator, and the total line amounts.

  • Publication number: 20220099346
    Abstract: A sensor control system includes: a refrigerant leak sensor configured to, when powered, measure an amount of a refrigerant present in air outside of a heat exchanger of a refrigeration system, where the heat exchanger is located within a building that is at least one of heated and cooled by the refrigeration system; and a power control module configured to one of: continuously power the refrigerant leak sensor; and disconnect the refrigerant leak sensor from power when a blower that moves air past the heat exchanger is on.
