  • Publication number: 20250164193
    Abstract: In one aspect, a heat transfer apparatus including a process fluid heat exchange circuit having a mechanical cooler with hot and cold side heat exchangers and a hybrid cooler to receive process fluid from the hot side heat exchanger and provide cooled process fluid to the cold side heat exchanger. The hybrid cooler includes direct and indirect heat exchangers. The hybrid cooler has a dry mode and a hybrid mode. The heat transfer apparatus includes a controller configured to operate the process fluid heat exchange circuit in one of a plurality of modes based at least in part upon a determination of a thermal duty of the heat transfer apparatus.

  • Publication number: 20230417494
    Abstract: In one aspect, a heat transfer apparatus for an industrial process that requires process fluid at a process fluid set temperature. The heat transfer apparatus includes a process fluid heat exchange circuit having a heat exchanger, an airflow generator, and a thermal energy storage. The controller is configured to operate the process fluid heat exchange circuit in a second mode wherein the thermal energy storage transfers heat between the process fluid and the thermal energy storage and the heat exchanger transfers heat between the process fluid and the air based at least in part upon a parameter of the air and a determination of the process fluid heat exchange circuit in a first mode, wherein the process fluid bypasses the thermal energy storage, being unable to provide the process fluid at the process fluid set temperature.
