The new Danfoss AK-PC 781 multifunctional rack controller simplifies set-up of energy-efficient capacity control of refrigeration compressors and condensers with modular hardware and flexible software that extends as system requirements grow or change, says the company.
Danfoss announced today that it has acquired full ownership of the joint venture company Danfoss Turbocor Compressors, in which Danfoss has had a 50 percent owner’s share since 2004. The company develops and produces high-efficiency variable speed compressors in the capacity range of 75-200 tons per unit.
Green seemed to be all the rage several years ago, both inside and out of the HVACR industry. But is it the buzzword it once was? In 2012, what does green mean for the HVACR industry and what are customers, especially commercial customers, seeking?
The Evolution® Extreme variable-speed heat pump (280ANV) has efficiencies of up to 13 HSPF and up to 20.5 SEER. When combined with an Evolution control and Evolution gas furnace or fan coil, the heat pump utilizes a variable-speed compressor to precisely match its operation to the heating and cooling needs of the home.
The YORK® YVWA water-cooled screw chiller features energy-saving variable-speed technology. The design of the chiller, with energy-saving variable-speed technology, helps cut energy costs and carbon emissions by as much as 30 percent, said the company.
ClimateMaster recently announced its Trilogy™ 40 series has exceeded 40 EER at ground-loop conditions and been certified by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
Minimizing wear on HVAC equipment and maximizing system uptime is the VLT® HVAC Basic drive. It is a robust variable-speed drive solution that delivers highly reliable HVAC performance for basic fan and pump operations, the company said.
With a working pressure of 175 psi, the Viridian line of wet-rotor pumps with an ECM motor offers an 80 percent decrease in energy consumption compared to a standard commercial pump of the same size, says the company.
Expanding the TM9X and TM9V families, two models have been added to the Luxaire® LX Series of multiposition gas furnaces. An input rate of 40,000 Btuh enables the furnaces to provide better heat load matches, avoiding oversized equipment selection.
The Tempstar® SmartComfort® 96 percent-plus AFUE gas furnace line is available. The SmartComfort® VC 97 features a modulating gas valve, variable-speed ECM blower motor, 97 percent AFUE, and stainless steel primary and secondary heat exchangers. The SmartComfort VT 96 is a two-stage variable-speed model at 96 percent AFUE.
