  • Publication number: 20230296276
    Abstract: A heating, ventilation, air conditioning, and/or refrigeration (HVAC&R) system includes one or more sensors configured to acquire feedback indicative of an operational parameter of a component of the HVAC&R system. The HVAC&R system includes a control unit of the component that is configured to receive the feedback from the one or more sensors. The control unit is configured to analyze the feedback in accordance with a first control scheme to generate a first control output and to operate the component based on the first control output. The HVAC&R system includes a remote server configured to provide a cloud computing environment, where the remote server is communicatively coupled to the control unit via a network. The remote server is configured to receive and analyze the feedback in accordance with a second control scheme to generate a second control output and to operate the component based on the second control output.

  • Publication number: 20080310112
    Abstract: A system and method is provided for an electrical component enclosure that controls the temperature of the coolant in the internal coolant loop through the enclosure to prevent the formation of condensation on the coolant tubes. Warm coolant is diverted from a heat exchanger to a mixing valve where it is mixed with chilled coolant before entering the enclosure. Humidity and temperature levels are monitored within the enclosure and processed by a microprocessor to determine the temperature of the coolant needed in the tubes.
