Spirax Sarco has released a range of desuperheaters that offer an effective solution for steam conditioning and enhanced thermal energy transfer. The company says its desuperheaters provide the answer when precise control and reduction of superheated steam temperature is required.
Century Refrigeration, a division of RAE Corporation, has released the new Centinel™ Intelligent Defrost Control System. Company officials report that the control system improves refrigeration system energy efficiency, eliminates icing and fogging, and reduces operating costs.
Trane launched its ProSpace™ packaged terminal air conditioners (PTAC) for the hospitality industry. The system features humidity control for individual air-quality management, wireless thermostat and remote control capabilities, and an unobtrusive design that can blend in with a room’s décor.
The Grundfos PACOpaQ® is a fully-integrated and compact HVAC packaged pumping system designed for chilled and hot water distribution, condenser water, geothermal loop, district heating and cooling, and many other water-based systems. The system pairs centrifugal pumps with the intelligence and efficiency of a dedicated HVAC control, which automatically determines the most efficient speed and optimum number of pumps needed to meet desired flow and pressure.
Ten online professional development seminars focused on commissioning, environmental quality, energy efficiency, HVAC applications, and standards and guidelines are being offered this fall by the ASHRAE Learning Institute (ALI).
Weil-McLain says it is now offering its most advanced high-efficiency condensing boiler. The new 95% AFUE Evergreen boiler is designed with simple controls and flexible functionality for multiple applications.
The UV-Com™ Control Panel from UV Resources provides a convenient means of monitoring multiple Ultraviolet “C” (UV-C) fixtures installed in individual AHUs. The UV-Com automates the conventional means of “manually checking” that lamps and ballasts are operational and communicates this lamp status to most BAS/BMS. A single UV-Com control panel can simultaneously monitor up to eight separate UV-C fixtures. Multiple UV-Com panels can be linked together in a daisy-chain sequence in order to monitor as many individual UV-C fixtures as necessary.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
