Patent number: 11846456Abstract: A liquid slug reduction and charge compensator device for use in air conditioning and heat pump systems includes a housing having a cavity. The housing includes an inlet port providing an entry path into the cavity and an outlet port providing an exit path from the cavity. The housing further includes a liquid line port providing a refrigerant pathway into and out of the cavity. The liquid slug reduction and charge compensator device further includes a flash tube extending through the cavity and providing a passageway through the cavity such that a hot gas refrigerant that enters the cavity through the inlet port causes a liquid refrigerant that enters the flash tube to evaporate.Type: GrantFiled: May 17, 2021Date of Patent: December 19, 2023Assignee: Rheem Manufacturing CompanyInventor: Swapnil Khaire

Patent number: 11668503Abstract: A compression refrigeration system includes a switch to select between a plurality of operation modes of a metering device that controls a rate of flow of a refrigerant to an evaporator of the compression refrigeration system. Each operation mode is associated with a respective refrigerant. Further, the compression refrigeration system includes a reference database that comprises pressure-temperature data associated with a plurality of refrigerants. Furthermore, the compression refrigeration system includes a valve adjustment engine that is communicatively coupled to the switch and the reference database. The valve adjustment engine controls the metering device based on an operation mode of the metering device that is selected using the switch. The operation mode is selected based on a refrigerant with which the compression refrigeration system is currently charged.Type: GrantFiled: April 19, 2021Date of Patent: June 6, 2023Assignee: RHEEM MANUFACTURING COMPANYInventors: Harshad Inamdar, Christina Hughes, Derek Brasuell, Sivakumar Gopalnarayanan, Swapnil Khaire
