Patents by Inventor Kamalakkannan MUTHUSUBRAMANIAN

Kamalakkannan MUTHUSUBRAMANIAN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11555627
    Abstract: A system is provided and includes a first controller, a non-transitory computer-readable medium and a second controller. The first controller is configured to control operation of at least one compressor circuit including one or more compressors. The non-transitory computer-readable medium is configured to store instructions of a stage profiler for execution by the controller. The instructions include: determining a target system capacity profile for the at least one compressor circuit; determining system stage capacities for stages of the at least one compressor circuit; selecting some of the system stage capacities based on the target system capacity profile to provide an available system capacity profile; generating modulation information based on the available system capacity profile and a load request signal; and controlling operation of the one or more compressors based on the modulation information and according to the available system capacity profile.

  • Patent number: 11333412
    Abstract: A climate-control system may include a first fluid circuit, a desiccant system, and a second fluid circuit. The first fluid circuit may include a desorber, an absorber, and an evaporator. A first fluid exits the desorber through a first outlet and flows through the evaporator and a first inlet of the absorber. A second fluid exits the desorber through a second outlet and may flow through a second inlet of the absorber. The desiccant system includes a conditioner and a regenerator. The conditioner includes a first desiccant flow path. The regenerator includes a second desiccant flow path in communication with the first desiccant flow path. The second fluid circuit circulates a third fluid that is fluidly isolated from the first and second fluids and desiccant in the desiccant system. The second fluid circuit may be in heat transfer relationships with the first fluid and the first desiccant flow path.

  • Patent number: 10830516
    Abstract: A control system for controlling an output for a plurality of compressors includes a control unit receiving a first value from a first sensor and generating a first output based on the first value. The control unit receives a second value from a second sensor and derives a final output from the first output and the second value. A plurality of compressors receives the control commands from the control unit based on the final output.

  • Patent number: 10704817
    Abstract: A control system for controlling an output for at least one compressor includes a control unit that receives an indoor set point and an outdoor ambient temperature. The control unit determines a load request based on the indoor set point and the outdoor ambient temperature without considering an indoor room temperature. The at least one compressor receives control commands from the control unit based on the load request.
