The Ice Cub is a compact, home-optimized HVAC system comprised of an ultra-high-efficiency compressor and ice tank with heat exchanger. The compressor operates in multiple modes. It can cool the home like a conventional a/c unit or, store energy in the form of cooling by freezing water in the ice tank.
Bitzer has announced it has modified all models of its two-stage reciprocating compressors to enable them to run with R-448A and R-449A refrigerant. The refrigerants have global warming potentials (GWPs) of 1,386 and 1,397 respectively.
A series of geothermal heat pumps from Enertech Global swept the HVAC Light Commercial Equipment category of the 2015 Dealer Design Awards, starting with the gold award winner, the TVS/TVT TETCO Commercial Series Geothermal Heat Pump.
The Danfoss Turbocor VTT series of compressors takes the benefits of magnetic bearing technology up into larger capacity ranges where the current Turbocor TT series leaves off. VTT compressors introduce IntraFlow™ technology that enables chiller systems up to 1,000 tons or more to provide improved reliability and increased efficiency.
‘Advanced Linear Refrigerant Compressor’ Has a Variety of Applications
October 6, 2014
Ray McKenzie and Mac Chaney of Dothan and Madison, Alabama, have developed a new compressor that they claim has the potential to revolutionize the HVAC and refrigeration industries. The unit is said to be up to 50 percent more efficient than conventional equipment, and is also small, lightweight, and quiet.
Any time an oil pressure control shuts down a compressor, the cause of the shutdown must be identified. The tripped control is a warning of another existing problem. Simply resetting the control will not solve the problem.
Bitzer’s new Ecoline Varispeed compressor features an integrated suction-gas-cooled VFD that significantly lowers operating costs and ensures reliable and effective performance, even at high ambient temperatures.
The 30-hp R-410A Copeland Scroll™ compressor features CoreSense™ Communications modules, which provide commercial air conditioning customers advanced diagnostic and protection benefits. By using the compressor as a sensor, valuable system data can be accessed and monitored.
