Critical Systems Testing Critical Systems Testing (CST) has found a way to gain an edge with "Special Come Out, Come Out, No matter where you are" tool" - Start Onset's HOBO series of data loggers, a small portable logger that reveals a wide range of information is hard to find.
Critical Systems Testing Critical Systems Testing (CST), a Colorado-based reliability and energy saving company, verifies that automated systems operate within the specifications of data center equipment, usually during commissioning or system commissioning. This is an important task for many reasons, crucially, data centers house the equipment necessary to keep America's online economy running.
In addition, data centers use a lot of energy -- 10 to 30 times the average office building, according to Lawrence Berkeley National Laboratory. It is estimated that global emissions data centers will quadruple by 2020.
How can the data center improve energy efficiency? This is the beginning of the HOBO series ZW series wireless data nodes play a role in real-time detection of temperature, humidity, power consumption and other measurements ZW-001, ZW-003, ZW-005, ZW-006, ZW -007, ZW-008, ZW-RCVR, ZW-ROUTER. Wireless data nodes transmit data from various points in a data center facility to a central receiver connected to a computer. This eliminates the need to manually offload data from multiple individual data loggers.
In a typical data center test application, data nodes are set up to form a scalable wireless sensor network, and additional test points can be added over time. Utilizing self-healing network technology, the node data receivers of ZW-ROUTER can be automatically routed despite obstacles, without manual intervention. The optional router ZW-ROUTER supports data hopping across room, partition and floor levels, and each data node can be set in dual mode - data recording and data routing network to provide more flexibility.
The accompanying HOBOware®Pro software provides real-time graphs, alarm notifications, and network map functions for each metering point, providing an approximate image of each node of the wireless sensor network that can be easily located on the site floor plan.
"Data centers have gone through a much more stringent testing process than a typical office building. These are mission-critical applications that have a higher level of testing," said Michael Rosenberg, operations manager at CCS. "Real-time data access is very important. In many cases we need real-time data to show us what happened instantaneously and what temperature conditions in different test scenarios. Finally our commissioning process, we will go through this process called is (Integrated Systems Testing), which is a full three to four day process in which we look at electromechanical systems and how they interact."
Energy waste is not always apparent because of the complex relationships among systems in a data center. But the wireless HOBO series of data nodes, brings the entire data center strategy to light by revealing true operating conditions. For example, a temperature reading may be overcooling beyond the system's design intent in the displayed area. Raising the temperature of these points can reduce the energy consumption of the data center.
"Many data center systems already have complex automation systems with built-in temperature monitoring equipment, Zhongke Commission. But the monitors usually only measure the temperature at fixed locations ZW-001, ZW-003, ZW-005, ZW-007. Onset data loggers provide We are able to measure instrument conditions in locations that, built into equipment, automation systems, would not provide," Rosenberg said.
This facilitates fine-tuning of wireless sensor networks to collect data from remote points without the need to run wires and cables.
Onset data nodes may also help Zhongke reveal that if control equipment, such as dampers, valves and variable speed drives, ZW-005, ZW-006, ZW-007, ZW-008 are not operating properly, a problem a data center manager may not be aware of. Zhongke uses a variety of Onset's plug-in accessories such as CO2 sensors, pressure transmitters and air velocity sensors, in addition to the logger's built-in temperature and humidity capabilities. These devices are prone to burst plug-in data nodes for external input and can be used to assess other operating conditions that can indicate wasted energy. For example, low CO2 level readings or high space pressure can indicate excessive ventilation. Excessive air velocity coupled with cold equipment racks can also indicate wasted air distribution.
"We can address deficiencies at the component level and redesign a control sequence to address performance-related issues and improve energy efficiency," Rosenberg said.
By adjusting the way data is collected, measured and analyzed, Zhongke above is able to serve customers beyond job requirements. Data Node helps Zhongke discover how automated systems not only meet, but can also exceed design expectations.
“Tune often, if engineers want to optimize the energy efficiency of the system. Optimizing energy can be similar to an onion, with layers of multiples. Each process improvement can enable other deficiencies that need to be addressed. Coupling emerges from data node equipment automation The system helps us evaluate equipment operations from the load side through the energy usage pipeline," Rosenberg said.
Zhongke Inspection Systems also provides valuable measurement data centers - and any building complex automation systems during their tenure. Buildings are in one operation and additional opportunities can be identified to increase their efficiency.
"Equipment can achieve 70 percent of its energy saving potential by completing the formal commissioning process; the remaining 30 percent will be through fine-tuning the system after construction is occupied and operational," Rosenberg said. "The continuous process achieves the highest level of operational efficiency in today's complex automation systems."
Zhongke has been using data loggers for many years and is especially pleased with starting new wireless technology.
"ZW has been using these ZW series loggers since earlier iterations. The next logical step in the technological evolution of wireless technology. It allows ZW to display its customer data in real-time during commissioning. It avoids the installation process of the ZW series The logger takes a week, pulls down the trend data table, and then analyzes it. The wireless ZW series loggers provide greater flexibility. We can pull down the data at any time, and provide the analysis process in an instant, enabling the control system to adjust. This flexibility Provides a greatly improved process and system analysis for commissioning," he said.
Onset data loggers and wireless sensors will continue to play an important role in Spring International Travel as its business develops. "Data loggers are an important tool for us. We can complement any building automation system that can be monitored with data loggers," he said.
