Abstract: The present disclosure relates to an enclosure of a vapor compression system, where a component is disposed within the enclosure. The component is fluidly coupled to the vapor compression system and configured to discharge a flow of fluid. The enclosure includes a hole within a portion of the enclosure and a relief valve disposed within the hole of the enclosure, where the relief valve is configured to discharge the flow of fluid in a first direction through a passage within the relief valve. The passage extends from an interior region of the enclosure to an environment external of the enclosure. The relief valve is configured to block a second flow of fluid through the passage in a second direction, where the second direction is opposite of the first direction.

Abstract: A building management system (BMS) includes building equipment configured to provide samples of one or more data points in the building management system and a timeseries service. The timeseries service is configured to identify a first timeseries processing workflow that uses an input timeseries as an input and defines processing operations to be applied to the samples of the input timeseries, perform the processing operations defined by the first timeseries processing workflow to generate a first derived timeseries comprising a first set of derived timeseries samples, identify a second timeseries processing workflow that uses the first derived timeseries as an input and defines processing operations to be applied to the samples of the first derived timeseries, and perform the processing operations defined by the second timeseries processing workflow to generate a second derived timeseries comprising a second set of derived timeseries samples.

Abstract: A heat pump system includes a refrigerant circuit that has a compressor, a first heat exchanger, a second heat exchanger, a reheat heat exchanger, a modulating valve, and a reversing valve. The reversing valve is configured to transition between a first configuration to direct refrigerant from the compressor toward the modulating valve and a second configuration to direct the refrigerant from the compressor toward the first heat exchanger. The heat pump system also includes control circuitry configured to concurrently maintain the reversing valve in the first configuration and adjust a position of the modulating valve to direct a first portion of the refrigerant from the modulating valve to the second heat exchanger and a second portion of the refrigerant from the modulating valve to the reheat heat exchanger based on an operating mode of the heat pump system.

Abstract: An adaptive flow limit controller for controlling a flow rate of a fluid through a heat exchanger includes a processing circuit. The processing circuit is configured to use an adaptive model to determine a threshold flow rate of the fluid through the heat exchanger at which a gradient of a temperature difference of the fluid across the heat exchanger with respect to the flow rate of the fluid through the heat exchanger has a threshold gradient value. The processing circuit is configured to operate a flow control device to maintain the flow rate of the fluid of through the heat exchanger at less than or equal to the threshold flow rate.

Abstract: A HVAC controller includes a housing and one or more heat-generating components contained within the housing. The heat-generating components cause a temperature inside the housing to exceed a temperature outside the housing. The controller includes a temperature sensor configured to measure the temperature inside the housing and a controller event detector configured to detect, for at least one of the heat-generating components, a controller event that generates heat inside the housing. The controller further includes a temperature compensation module configured to identify a steady-state temperature gain associated with the detected controller event, to calculate a temperature offset using a summation of the steady-state temperature gain, to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing, and to store the temperature offset.

Abstract: A method for applying semantic information to data in a building management system (BMS). The method includes receiving unrecognized data from equipment associated with the BMS, the unrecognized data comprising a first value and an associated device identifier; providing the unrecognized data as input to a first learning model to generate a first output, the first output indicative of semantic information corresponding to the first value evaluated individually; providing the unrecognized data as input to a second learning model to generate a second output, the second output indicative of semantic information corresponding to the first value evaluated in context of a second value associated with the device identifier; and applying semantic information to the unrecognized data based on the first output and the second output. The method allows for users to configure building management systems with automatically generated semantic data tags.
