摘要： A method for controlling power consumption includes receiving a flexibility request from an electrical utility and discovering energy relevant devices in a building. The energy relevant devices include electrical loads and alternative energy sources. Power requirements are predicted from an electrical utility for the loads, the prediction takes into account available power from the alternative power sources. Power set points are determined for the energy relevant devices based on the prediction. The power set points meet the flexibility request. The energy relevant devices are directed to operate at the power set points. A building energy management system is also disclosed.

摘要： A system for smoke/fire discrimination and identification of the fire source is provided. The system comprises a control unit that is configured to receive data pertaining to gases present in the smoke generated by a burning material and receive data pertaining to temporal characteristics of fire caused by the burning material. The control unit identifies the burning material based on the data pertaining to the one or more gas and the data pertaining to temporal characteristics of fire; and trigger a fire event based on the identified burning material. The control unit identifies and classifies the burning material as one of the known burning materials based on matching of the detected gas and the captured temporal characteristics with the database.

摘要： An illustrative example embodiment of a structure for supporting a heating, ventilation and air conditioning (HVAC) unit includes a frame having support members configured to be situated beneath the HVAC unit to support a weight of the HVAC unit, which is directed in a vertical direction. The frame is at least partially situated in a plane that is perpendicular to the vertical direction. A supply air passage and a return air passage are supported by the frame. The return air passage has a first side and a second side opposite the first side. The first side is oriented at a first oblique angle relative to the plane. The second side is oriented at a second oblique angle relative to the plane. The first oblique angle is different than the second oblique angle.

摘要： A safe including a lock actuator and a control system communicatively connected with the lock actuator, and a method for controlling a lock actuator of a safe are provided. The lock actuator is configured to lock or unlock a mechanical or electronic lock of the safe. The control system includes a transmitter, a receiver, and a processor. The transmitter is configured to emit light (ex. infrared light) into the safe. The receiver is configured to receive light, for example, the same infrared wave, emitted from the transmitter and generate an output signal. The processor is configured to receive the output signal from the receiver and determine whether item is inside the safe. The control system disables the lock actuator from locking the safe when the output signal indicates no item is inside the safe.

摘要： A system in a transport refrigeration unit (TRU) for driving a compressor and/or fan(s) of the TRU by a variable frequency drive (VFD) that is operable using AC power comprises the VFD operatively connected between the compressor and one or more ac power source such as an engine-generator assembly of the TRU and/or an electrical grid. The same VFD or a different VFD is also operatively connected between the AC power source and fan(s) associated with an evaporator, and a condenser of the TRU. The VFD is configured to be operated by the AC power sources. The VFD is operable to receive a 3-phase AC power ranging from 200 to 650 volts and 0.25 to 25 KW from at least one of the AC power source, convert the received 3-phase AC power to supply AC or DC power to a motor associated with the compressor and/or the fan(s).

摘要： A rooftop HVAC unit includes a cabinet, an energy recovery wheel, dampers, and a controller. The energy recovery wheel is configured to be mounted within the cabinet. The energy recovery wheel is configured to transfer heat between an outdoor air stream and a return air stream when in an operational mode, and is further configured not to transfer heat between the outdoor air stream and the return air stream when in a bypass mode. The dampers can direct the outdoor air stream and return air stream through the rooftop HVAC unit, either through the energy recovery wheel or around the energy recovery wheel. The controller is configured to adjust the dampers based on a selection between the operational mode and bypass mode of the energy recovery wheel.

摘要： A method and system for monitoring for leakage of flammable compounds is disclosed. A first parameter is measured indicative of the presence flammable compounds in a space around a potential leak source of a flammable compound, and a presence of the flammable compound is prospectively determined based on measurement of the first parameter. Additionally, a second parameter is measured in the space around the potential leak source. The prospective presence of the flammable compound determined by measurement of the first parameter is characterized, in conjunction with the measurement of the second parameter, as an actual presence of the flammable compound or as a false alarm.
