Design and Installation of Electric Control System for Four-Tube Fan Coil

结合武汉国际博览中心洲际酒店中央空调系统的组成及运行原理,介绍四管制风机盘管的电气控制系统设计与安装。根据四管制风机盘管性能及其回水管上的电动调节阀的工作原理进行控制系统设备选型,设备主要包含液晶温控面板及中间继电器。该控制系统可实现风机盘管及电动调节阀的协调运行,调节室内温度,从而满足用户需求。

In combination with the composition and operation principle of central air conditioning system in Wuhan international Expo Central Continental Hotel, this paper introduces the design and installation of the electric control system of the four tube fan coil unit. According to the performance of the four tube fan coil unit and the working principle of the electric regulating valve on the return pipe, proceed the selection of control system equipment. The equipment mainly includes LCD temperature control panel and intermediate relay. The control system can realize the coordinated operation of the fan coil unit and the electric control valve, adjust the indoor temperature, so as to meet the needs of users.
