| Energy Impacts of Chilled-Water-Piping Configuration By ROY S. HUBBARD, Johnson Controls Inc., York, Pa. |
| As the cost of energy continues to rise, it behooves chiller-plant owners and designers to consider the energy impacts of virtually everything under their control, including chilled-water piping. This article discusses the energy consumption of the three basic configurations of chilled-water piping currently in use: constant primary flow, constant primary flow/variable secondary flow, and variable primary flow. It also discusses the attributes of equipment-room space, installed cost, and control complexity. [MORE] |

Heating circulator Bell & Gossett's energy-efficient SMART heating circulator uses a unique technology to achieve significant energy savings while delivering hot water throughout a commercial or residential property. Featuring electronically-commutated-motor technology and a patented spherical motor design, ecocirc pumps eliminate the need for a conventional shaft, seal, and bearing assembly. Other special features of the pumps include control modes (auto for automatic proportional pressure control and vario for stepless speed control with a constant curve) and maintenance-free, long-lasting operation. The pumps are seal-less and leak-free, as well as self-lubricating and automatically cooled by pump media. Energy savings pay back the cost of the pumps within months. [MORE]—Bell & Gossett
Airflow-measurement damper Ebtron Inc. and TAMCO completed joint engineering, testing, and production-system integration for the AIR-IQ airflow-measuring-damper assembly. Comprehensive testing verified reliable unducted accuracy of ±5 percent of reading throughout the entire measurement range and up to Class 1A damper-leakage performance for compliance with ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. A wide range of damper models and options provide designers with thermal-break frame design, thermally insulated airfoil blades, a salt-water-corrosion-resistance option, and dual-bearing and slip-proof-linkage designs for maintenance-free operation and 20-plus-year service life.
