A review of optimization approaches for controlling water-cooled central cooling systems

Development of a personalized thermal comfort driven controller for HVAC systems

This paper introduces Insect Intelligent Building (I2B), a new architecture of building control systems based on Internet of Things (IoT). It has the following key features that are missing in the traditional solutions: (1) it has built-in agent models for space units and control devices; (2) it has built-in link models for immediate connections between space units and control devices; (3) it assigns a smart controller (called insect) for each space unit or each control device with six data ports (called legs) and these controllers communicate with each other only through their data ports according to the link models; (4) it decompose various building operation/management commands into computing tasks that run on smart controllers and depends on the collaborations among neighboring controllers to achieve the desired effects of the commands. Different from the traditional centralized solutions, this new architecture allows the building control systems to be developed in before the buildings are really built and simplify the installation and configuration of the building control systems.

Optimizing multi-chiller dispatch in HVAC system using equilibrium optimization algorithm

A decentralized algorithm for optimal distribution in HVAC systems

The invention provides a centerless network based water pump system, a water pump controller, and a control method of a water pump system. The method comprises the following steps: water pumps in the water pump system are each provided with a controller, and all the controllers are interconnected to form a centerless network; when it is determined that certain trigger conditions are reached, the water pump controllers initiate adjusting tasks; the water pump controllers start interactions with adjacent water pump controllers; and after the plurality of interactions, the whole system reaches predetermined convergence conditions, operation parameters after the water pumps are optimized are determined, and according to the optimized operation parameters, the corresponding water pumps are controlled to reach corresponding operation states. According to invention, the method is based on the centerless network, the water pumps connected in parallel complete a control objective equally, independently and coordinately, an optimal control scheme is worked out in a distributed mode, the workload of manual configuration adjustment by use of a traditional control mode is greatly reduced, the purpose of plug-and-play of control equipment is achieved, and the control efficiency, robustness and expandability of the system are improved.

Centerless network based water pump system, water pump controller and control method

The utility model provides a water pump system and pump control ware based on there is not central network, this water pump system includes: water pump and a plurality of controller of a plurality of parallelly connected settings, a plurality of controller one -to -one ground link to each other with a plurality of water pumps, and all controller interconnection are in order to form no central network, when the judgement of pump control ware reaches certain triggering condition, initiate the regulation task by this pump control ware, the pump control ware begins to go on alternately rather than adjacent pump control ware, entire system reaches the predetermined condition of convergence after several times are mutual, confirms the operating parameter after every water pump is optimized, reaches corresponding running state according to the corresponding water pump of operation parameter control after optimizing. The utility model discloses make each parallelly connected water pump equally independently coordinate the complete control target, calculate the optimal control scheme distributedly, reduced the work load of the artifical configuration debugging of conventional control form, realized controlgear's plug -and -play, improved control efficiency, robustness and the scalability of system.
