Abstract


With continuously improve the comfort of indoor thermal environment requirements , the central air-conditioning systems in large buildings used more and more widely used. Because of its complex structure , subsystem numerous and dispersed , the need to establish a network control system , centralized management of the unit and the device at the end , the purpose of decentralized control , in order to save energy, and improve the level of property management objectives . Central air conditioning is the most commonly used end device due to fan coil , fan coil control strategies of the pros and cons of a direct impact on the effect of the operation of the air conditioning system , this paper the main target for the the cluster control strategy of the fan coil units . This article briefly describes the current building HVAC control system development status , detailed description of the structure of the fan coil system connection performance analysis of fresh air fan coil air-conditioning system operating conditions , highlights fan variable water volume of the coil units , VAV operation to adjust the way . Secondly, with the current development of network control technology , centralized control of commonly used network protocol model , focuses on the characteristics and working principle of the RS-485 communication protocol . Next , the paper focuses on the the group control strategies of the fan coil units , and in turn is controlled from the partition -sharing control season control aspects of operating conditions to discuss some targeted control method from the point of view of a favorable energy . Finally , from the two aspects of hardware design and software design , fan coil control system in a practical engineering build process detailed analysis and description .
