A three-dimensional (3D) visual monitoring method for a building, a 3D visual monitoring system for a building, and a storage medium. The 3D visual monitoring method for a building includes acquiring a building information modeling (BIM) model and sensor data of a building, the sensor data being collected by a sensor arranged in a building area; integrating the sensor data into the BIM model; and transmitting the integrated BIM model to a display terminal, for use in a monitoring operation of the building.

An evacuation controller, an evacuation control system, and a mobile communication terminal. The evacuation controller includes: a local control unit capable of storing or acquiring evacuation path information to or from a cloud via a mobile communication terminal, wherein the evacuation path information is configured at least based on a layout of a building and a location of a danger occurred in the building. According to the evacuation controller and the evacuation control system, exchange of evacuation path information between the local control unit and a remote provider service system is realized through exchange between the mobile communication terminal and the cloud; or by configuring evacuation path information directly in the local control unit, the local control unit can clearly and timely learn about the local evacuation path information and can evacuate people based on the local evacuation path information.

A system for controlling an absorption chiller includes feedback control loops determining adjustments to system cooling and heating capacities and a controller for simultaneously adjusting positions of an energy input valve, a hot water valve, and a chilled water valve. The controller adjusts valves based on desired adjustments to system cooling and heating capacities and performance maps characterizing relationships between cooling capacity and heating capacities and valve positions. A method for controlling an absorption chiller includes the step of obtaining a performance map characterizing heat energy input to cooling and heating loops as functions of valve positions. To obtain the map, the hot water valve is held in a substantially constant position while the chilled water valve is modulated. Similarly, the hot water valve is modulated while the chilled water valve is held in a substantially constant position.

Turbulators are disclosed for use in a high-stage generator for an exhaust-fired absorption chiller/heater. The turbulators are designed to minimize pressure drop across the turbulator, and thus minimize the efficiency loss to the exhaust source. One turbulator design has a number of flanges extending at a non-normal angle to a central web. Further, some of the flanges have cutout portions. The overall turbulator design is intended to minimize wake downstream of the turbulator blades, which could otherwise cause undesirable pressure drop. A second turbulator design incorporates flanges that extend at a normal angle relative to the central web, but wherein the flanges have a non-rectangular cross-sectional shape. Again, the goal of the turbulator designs here is to minimize wake, and potential pressure drop.

A control for controlling the amount of heated fluid entering the inlet of the driving heat source for a refrigerant absorption cycle is controlled to vary the relative amount of heated fluid entering the driving heat source inlet, and being dumped to atmosphere. Preferably, a diverter valve is utilized such that a first valve body () communicates the flow into the driving heat source inlet, and moves in opposition to a second valve body () controlling the flow through the exhaust. The two valves bodies () are preferably mechanically linked. Since the heated fluid is not allowed to enter the refrigerant absorption cycle as its drive heating source, no additional hardware and control for dumping excess heat is necessary within the refrigerant absorption cycle. A computer control preferably drives the first valve to a precise position and the linkage ensures the second valve is also received at a precise position.

A discharge collector and diffuser for a screw compressor, including a housing having an inlet for receiving flow from a compressor and an outlet and defining therebetween a collector portion, a transition portion and a diffuser portion, the collector portion being adapted to receive a plurality of non-parallel streams from a compressor and to guide the streams into a substantially parallel flow direction, the housing further having a splitter plate positioned in the collector portion to separate the non-parallel streams from each other, whereby the streams are maintained separate until they are substantially parallel, thereby reducing flow losses.

A compressor for compressing refrigerant in an air conditioning or refrigeration system, including a housing having a suction port, a discharge port, and a compression chamber, a mechanism for producing a compression cycle for compressing the refrigerant, wherein the compression cycle occurs in the suction port, discharge port and compression chamber, and a mechanism for providing liquid refrigerant into the compression cycle at a desired location for reducing pressure pulsations and associated radiated noise produced during the compression cycle.

Liquid injection for reduced discharge pressure pulsation in compressors

A screw compressor includes at least two components defining at least two operating zones of different pressure and having surfaces defining a flow point between the at least two zones, and a surface treatment positioned on the surfaces so as to reduce clearance between the surfaces, and thereby reduce leakage through the flow point.
