WaterFurnace International has introduced the Envision® 30-ton water source heat pump, which the company says offers efficiencies that exceed ASHRAE 90.1 standards. Featuring a modular, take-apart design, the 30-ton unit can be moved into a building in two different sections, providing a reduced weight, smaller footprint, and improved maneuverability. Each piece fits in freight elevators and through doorways for convenience. When the unit is ready for installation, the sections can be rejoined.
On April 22, Danfoss welcomed the Economic Development Council of Tallahassee/Leon County at its facility in Tallahassee, FL, to discuss the impact of research and development and manufacturing operations on the local economy.
Johnson Controls has introduced the Quantech Air-Cooled Chillers. The company says the chillers offer up to 50% annual energy cost savings compared with the replaced chillers, have a low lifecycle cost, meet or exceed ASHRAE standards, and help earn LEED credit with a low refrigerant charge. Three models make up the Quantech chiller line. The QTC2 (15-50 tons) provides chilled water for all air conditioning applications using central station air handling or terminal units. The state-of-the-art installation uses tube and fin condensers, brazed plate evaporators, and scroll compressors.
A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation.
