Patent number: 10983542Abstract: Disclosed is a load-predicting and control system for a subway heating, ventilation and air conditioning system. In one aspect, a load-predicting and control system for a subway heating, ventilation and air conditioning system is provided. The system includes a basic database, a sensing system, a load predicting unit, and a controller; the basic database stores historical data; the sensing system provides measured data; the load predicting unit calculates a predicted load value of the subway heating, ventilation and air conditioning based on the historical data and the measured data, and transmits the predicted load value to the controller; the controller issues a control command based on the predicted load value. Also provided is a load-predicting and control method for the subway heating, ventilation and air conditioning system. The present disclosure solves problems such as poor accuracy of conventional load prediction and inadequate control of the air conditioning system.Type: GrantFiled: February 20, 2019Date of Patent: April 20, 2021Assignee: Gree Electric Appliances, Inc. of ZhuhaiInventors: Dongjun Sun, Sheng Wang, Juan Wang, Guolin Liu, Yusong Liu

Patent number: 10955172Abstract: Disclosed is a high-temperature air conditioning device. By changing an arrangement mode of throttle valves, a pressure of refrigerant inside a low-pressure pipeline is made to be lower than a pressure of refrigerant inside a medium-pressure pipeline, thus ensuring that the refrigerant, used for cooling components, inside the low-pressure pipeline has a low pressure, thereby solving a problem in the prior art that a frequency converter, a motor and lubricating oil are not cooled sufficiently or cannot be cooled due to excessively high evaporation pressure.Type: GrantFiled: November 20, 2018Date of Patent: March 23, 2021Assignee: GREE ELECTRIC APPLIANCES, INC. OF ZHUHAIInventors: Hua Liu, Hongbo Li, Zhiping Zhang, Sheng Wang, Dongjun Sun

Patent number: 10445298Abstract: Systems and methods of enabling a service level agreement to specify interactions between an application and a remotely located object store that manages data as objects. A computing device receives data associated with a request to write application data to an object store according to a schedule, wherein the data is file system data. The computing device creates a snapshot associated with the requested application at a snapshot pool, and transmits instructions to a cloud formatting engine to create a virtual disk at a storage pool associated with an object store. The computing device copies the snapshot from the snapshot pool to the virtual disk, the snapshot comprising file system data and transmits instructions to the cloud formatting engine to convert the data associated with the first snapshot into an object, and move the object from the virtual disk to the object store.Type: GrantFiled: May 18, 2016Date of Patent: October 15, 2019Assignee: Actifio, Inc.Inventors: Ashok Thittapullimadam Ramu, Boris Vladimir Protopopov, Yong-Min Chen, Dongjun Sun, Tracy Melbourne Taylor, Yeganjaiah Gottemukkula, Bhargava Kumar Kancherla

Patent number: 10282201Abstract: Systems and methods are provided for automating a provision of applications from a source to a target by providing a virtual copy of application data, wherein the virtual copy can be adapted to a plurality of different target environments. Versions of source application data from an application database at a source production server are maintained at times associated with a schedule. Data associated with a request is received from a user to provision the source application data for a target environment at a target server, the request further comprising application specific parameters that define necessary requirements for the target environment. A virtual copy of the source application data is presented to the target server. Instructions to the target server are transmitted that define how to restore an operational server database from the virtual copy based on the application specific parameters to meet the requirements of the target environment.Type: GrantFiled: April 29, 2016Date of Patent: May 7, 2019Assignee: Actifo, Inc.Inventors: Uday Tekade, Xiangdong Zhang, Sachindra Kumar, Madhav Mutalik, Yeganjaiah Gottemukkula, Yong-Min Chen, Ankur Bhargava, Dongjun Sun

Patent number: 7600229Abstract: Mechanisms and techniques for processing information in a management application, such as a storage area network management application, include a load manager, a set of distributed agents that collect information, and a set of store process that store the agent-collected information. The load manager receives load information from a plurality of store processes. The load information indicates a relative processing load for respective store processes. The load manager determines store process availability based on the received load information. The load manager receives a store assignment request from an agent that has an agent transaction to perform with a store process and assigns a store process of the plurality of store processes for the agent to use to perform the agent transaction based on the determined store process availability.Type: GrantFiled: September 30, 2003Date of Patent: October 6, 2009Assignee: EMC CorporationInventors: Samuil Shmuylovich, Ilya Liubovich, Eric Young, Dongjun Sun, Boris Farizon
