HVAC systems with strict space humidity requirements should be controlled for a constant discharge air dew point temperature (or maximum discharge air dew point) in addition to controlling to a set discharge dry bulb temperature.
PEX (crosslinked polyethylene) piping is becoming increasingly accepted and specified on commercial plumbing projects for its flexibility, physical properties, and ability to retain the most preferential aspects of metallic piping while improving upon them.
A proven HVAC technology wordwide, Variable Refrigerant Flow (VRF) zoning systems are poised for dramatic growth in all areas of commercial construction because they provide precise zones control that can contribute toward the achievement of LEED certifications.
The future of pervasive device communication is envisioned to be so powerful that everyday devices will be able to identify each other's presence and role, and interact in a manner that benefits our way of life. Such communication-rich environments will lead to embedded computation abilities, where information can be collected by devices and sensors, and processed to generate an intelligent response and coordinated actions. This white paper focuses on the benefits of integrating devices with enterprise and business processes and the importance of having holistic visibility over operational data.
IP telephony and power over Ethernet (PoE) are driving the requirement for increasing uptime levels, power capacity, and the need for dedicated precision air conditioning across the network. High-availability environments, such as data centers and computer rooms, may have the power and cooling infrastructure in place to handle these changes, but in many cases, equipment rooms and wiring closets do not. This white paper provides specific guidance on ensuring proper power and cooling support for the Cisco routers and switches operating in network closets and equipment rooms.
This paper describes a new CFD-based modeling
capability and design methodology that overcomes the limitations of
conventional guidelines and traditional CFD-based approaches and is
effective at addressing equipment related cooling and efficiency
problems in the data center.
Boiler Maintenance & Lifecycle Costs; Proper upkeep can seem like a high bar, but it's nothing compared to a drain on the budget, an avoidable full replacement, or an on-site incident, read more in January issue.
