摘要： ADAPTIVE LOGIC BOARD FOR VARIABLE SPEED DRIVE An adaptive logic board (100) for a variable speed drive (52), VSD, of a heating, ventilation, air conditioning, and refrigeration, HVAC&R, system includes a signal sensing circuit (154) configured to receive an input signal from a sensor (120, 130) of the VSD. The signal sensing circuit includes a filter (190) configured to condition the input signal. The filter includes a variable resistance element (184) configured to adjust a cutoff frequency of the filter. The filter is configured to attenuate waveforms in the input signal having frequencies that exceed the cutoff frequency to generate a conditioned signal. The adaptive logic board also includes a controller (164) configured to receive the conditioned signal and to adjust the variable resistance element to adjust the cutoff frequency of the filter based on a parameter of the HVAC&R system.

摘要： A hybrid cooling system for a hermetic motor includes an annular cavity in a motor housing that receives a vapor flow and an annulus in the motor housing that receives a liquid flow. The hybrid cooling system includes a sleeve disposed adjacent to the annular cavity and the annulus, where a radial opening is defined through the sleeve. The hybrid cooling system includes a stator at least partially surrounded by the sleeve, a gap defined between the stator and a rotor, and a vent slot of the stator configured to receive the vapor flow from the annular cavity through the radial opening of the sleeve and direct the vapor flow to the gap. The hybrid cooling system includes an exit path in the motor housing configured to direct an evaporated vapor flow, generated from the liquid flow contacting the stator, and the vapor flow out of the motor housing.

摘要： A building management system including building equipment operable to affect a variable state or condition of a building. The building management system includes a controller including a processing circuit. The processing circuit is configured to obtain a vibration data set related to vibrations of the building equipment. The processing circuit is configured to analyze the vibration data set by one or more machine learning models to generate a set of probabilities. The set of probabilities is related to a probability that the vibration data set is abnormal. The processing circuit is configured to identify the vibration data set as normal or abnormal based on the set of probabilities. The processing circuit is configured to initiate a corrective action responsive to identifying the vibration data set as abnormal.

摘要： A building control system includes one or more controllers configured to obtain comfort feedback provided by one or more occupants of a building in response to exposing the one or more occupants to a first set of environmental conditions of the building. The one or more controllers are also configured to generate, based on the comfort feedback, one or more thresholds defining a range of values for an environmental condition of the building within which the one or more occupants are predicted to be comfortable, execute a predictive control process subject to one or more constraints based on the one or more thresholds to generate setpoints for building equipment, and operate the building equipment to drive the environmental condition of the building toward the setpoints.

摘要： A device for illumination and fire safety in a room includes a housing, one or more light emitting devices, one or more fire safety components, and a controller. The one or more light emitting devices are coupled to the housing and configured to provide ambient lighting for the room during a normal mode of operation. The one or more fire safety components are coupled to the housing and configured to notify occupants of the room of a fire during an alarm mode of operation. The controller is configured to transition from the normal mode of operation into the alarm mode of operation in response to detecting the fire. The device may include facilities for remote self-testing which may include one or more of a light detector, a sound detector, and a smoke emission system. The device may perform the self-test in a test mode.

摘要： A controller for a building control system includes processors and memory storing instructions that, when executed by the processors, cause the processors to perform operations including identifying zones within a building, analyzing data associated with the zones, and generating zone groupings based on the data associated with the zones. Each of the zone groupings define zone groups and specify which of the zones are grouped together to form each of the zone groups. The operations also include identifying a particular zone grouping from zone groupings based on the data associated with zones and using the particular zone grouping to generate control signals to operate equipment of the building control system to provide heating or cooling to the zones.
