  • Method for optimizing pressure equalization in refrigeration equipment
    Patent number: 11300339
    Abstract: In a method for operating a compressor (22) having an inlet (26) and an outlet (28), the method includes: running the compressor to compress a fluid; shutting down (422) the compressor; determining (420) a condition-dependent threshold restart pressure difference (threshold) across the compressor; relieving the pressure difference to reach the threshold; and, after the threshold is reached, restarting (434) the compressor.
    Type: Grant

    Date of Patent: April 12, 2022
    Assignee: Carrier Corporation
    Inventors: Charles A. Cluff, Matthew T. Austin
  • Refrigerant charge management
    Patent number: 11215388
    Abstract: A system includes an indoor HVAC unit and an outdoor HVAC unit in communication with the indoor HVAC unit. The outdoor HVAC unit comprises a compressor, a vapor header in communication with the indoor HVAC unit and compressor, and at least one check valve to allow vapor refrigerant flow into the indoor HVAC unit during a cooling mode and to prevent liquid refrigerant from exiting the vapor header when in a heating mode. A method of operating said system is also disclosed.
