A system for predicting a surge of a centrifugal refrigeration compressor including a signal capturing module for capturing at least two signals relevant to the centrifugal refrigeration compressor; a feature extracting module defining a window period for extracting data of the at least two signals, and defining at least two feature functions respectively acting on the data in the window period of the at least two signals; and, a feature analyzing and deducing module calculating a feature value for each of the signals to map a probability value of surge prediction for each of the signals, and concluding, based on the probability value of the surge prediction of each of the signals, a final probability value to determine whether or not the surge will occur to the centrifugal refrigeration compressor.

System and method for predicting a surge of a centrifugal refrigeration compressor and air-conditioning unit

A building heating or cooling system is disclosed that includes an air handling system having an air delivery flow path in fluid communication with a conditioned space in the building. The building heating or cooling system also includes an electrocaloric heating or cooling system that includes first and second electrocaloric modules. A first inlet receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a first outlet to the conditioned space or the air delivery flow path, and a second inlet that receives air from the conditioned space or the air delivery flow path and directs it through the first or second electrocaloric module to a second outlet to outside the conditioned space.

Hybrid electrocaloric heat pump system

The present disclosure discloses a building evacuation system and a building evacuation method. The evacuation method comprises: capturing image data of a region by a plurality of sensors to track a moving state of people in the region; detecting, in the moving state of the people being tracked, an object specified by at least one set abnormal mode, and matching the object with the abnormal mode; and generating an indication representing an abnormality of evacuation behavior based on the abnormal mode after being matched. The present disclosure can provide efficient evacuation.
