Samtec公司., a manufacturer of electronic board components, in New Albany, Indiana.
The Samtec USA headquarters includes a variety of spaces with a wide range of functionality, 包括办公室, 一个制造工厂, 会议室和一个大的休息室, which made fresh-air ventilation a special concern for this project.
Samtec had an existing zoning system that was costly and difficult to use. 监控和控制暖通空调系统, the customer had to purchase unit controllers for each rooftop unit (RTU), as well as three network controllers that needed to be synchronized and separately maintained. 现有的接口面板是基于dos的, which limited configuration options and required maintenance personnel to program three separate devices.
在对设施进行检查后, the existing zoning system’s requirements and its ongoing costs, 选择了Lennox的L Connection®网络. A major factor in winning the bid was the L Connection Network’s sophisticated zoning capabilities that would treat each zone differently according to its needs. The L Connection Network can also integrate the Liebert equipment, which controls specialty HVAC equipment in the computer labs, allowing the customer to monitor all devices from a central location. 事实上, the Network provides an interface that can allow the customer to be notified of blower operation, 温度, 湿度, 还有更多在计算机实验室.
The heart of the network is the Integrated Modular Controller (IMC), a standard feature on Lennox’ premium rooftop units. Serving as the unit controller for each rooftop unit, the IMC:
The result is flexible and customizable comfort control, maximized equipment life cycle and reduced energy costs. Also, with the L Connection Network, a single device is able to control the entire network. 这个设备, 网络控制面板(NCP), has a simple-to-use interface that allows the user to monitor and control the RTUs locally or with PC software from a remote location via a phone modem, 以太网或互联网.
After consulting with Lennox’ Commercial Territory Manager Greg Luckett, 承包商罗伯茨加热, 空调制冷公司. included a Lennox® Comfort Sensor in each of the facility’s zones to monitor and control 温度 and relative 湿度. This gave each zone the proper amount of fresh-air ventilation, based on information communicated from the Comfort Sensor to the IMC. The Comfort Sensor is the only communicating zone sensor on the market today that combines CO2, 湿度 and 温度 sensing within a single device to minimize installation labor and reduce wall clutter.
With advice from Lennox’ 商业控制 Specialist Alan Bennett, L连接网络很快就安装好了, with the contractor planning to tie in most of Samtec’s rooftop units—which includes approximately 70 L Series® rooftop units—to the network for control from a centralized location. The flexibility of the L Connection Network provided a high level of customization, making it possible to integrate the zoned L Series constant-air-volume bypass (CAVB) units and additional non-zoned units into the system.
Because all of Lennox’ premium rooftop units have the built in IMC unit controller, 萨姆特克不再需要购买昂贵的靠谱的十大网投实体平台, 第三方单位控制器. The Network Control Panel (NCP) functions as the system controller, replacing the three controllers needed by the old system. 除了, the NCP Windows®-based software allows easy configuration, 监测和控制整个暖通空调系统.
“Installation of the L Connection Network on new construction applications is very straight forward,罗伯茨采暖公司的马特·拉克特说, 空调和制冷. “Lennox has done a great job writing their installation instructions and engineering manuals, which allow quick reference to the needed information in the field. With the new zoning configuration capability available on the L Connection Network software, Roberts can now offer its customers a complete energy management package that includes rooftop equipment and L Connection Network controls without the use of a third-party control system.”
“The customer wanted a single-point control system for their entire facility. They’ve been very impressed with the added control, relative 湿度 and 温度 in each zone made possible by the Comfort Sensors,Lennox的Greg Luckett说. “The L Connection Network has become a high value product for Samtec and allowed us to implement a sophisticated, 用户友好的系统，具有竞争力的价格.”
随着L连接网络的安装, 萨姆特克得到了改善, cost-effective monitoring and control of several types of units, 优秀的空气新鲜的风里, simple configuration and reduced energy and maintenance costs.
