Daikin Applied has introduced new developments with its Magnitude® WME Generation 2 magnetic bearing chiller. Firmly grounded in Daikin’s oil-free, magnetic bearing compressor technology, the Magnitude® WME Generation 2 builds on its performance with a redesign of the single compressor WME models from 400 to nearly 800 tons. The company says the Magnitude WME Generation 2 offers improved performance (especially in harsher climates), lower operating costs, and improved first costs.
Bosch Thermotechnology Corp. upgraded its SM Series, two-stage geothermal water source heat pump. Bosch redesigned its SM vertical and counterflow cabinets with an increased focus on serviceability and reliability, with front water connections and an all-aluminum air coil to resist formicary corrosion. Bosch says it also redesigned the internal layout for easier access through the front panel to components most often requiring service or adjustment.
Advanced Cooling Technologies, Inc. (ACT) has launched its HSC, HPC, and LNC series of sealed enclosure cooler products. Sealed enclosure coolers are used to dissipate heat inside enclosures or cabinets that house and protect electrical/electronic equipment from harmful environments.
Titus has introduced the new FlowBar architectural linear diffuser system. Officials claim the diffuser has been designed to maximize engineering performance without sacrificing aesthetic considerations for the designer. The company also says FlowBar’s performance allows higher airflows than conventional linear diffusers.
Greenheck’s line of Model EQB mixed flow inline fans has expanded with the addition of five new sizes. Now available in eleven sizes, 9 through 33, Model EQB offers a performance range up to 26,000 cfm and static pressure up to 3 in wg. All Model EQB sizes are licensed to bear the AMCA Seal for Sound and Air Performance.
SWEP reports that it is the first company to provide Brazed Plate Heat Exchangers (BPHEs) certified by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). Testing performed by their contracted laboratories verify that product performance is according to specified ratings. This offers additional security when selecting BPHEs for HVAC installations.
Greenheck has expanded its packaged rooftop ventilation line with the addition of Model RV(E)-120, a pre-engineered system featuring increased performance capabilities for larger dedicated outdoor air systems, multi-zone VAV systems, and single-zone VAV systems.
RectorSeal® has launched the MicroV ductless mini-split air-conditioner condensate pump, which the company says combines the quiet-running Silent+ technology along with a univolt power supply and plug-and-play power/communication connection cable.
Berner International Corp. has introduced a patented Venturi-style heater design, which the company says will offer a more aerodynamic, electric heated air curtain with improved air performance efficiency by up 40% The VTH electric heater combines a hemispherical heating element array with an innovative mounting strategy at the blower inlet. The patented design uses the Venturi effect to draw air through the heating element via the blower inlet before it enters the discharge airstream. The discharge airstream velocity remains unobstructed in a near 100% efficient heat transfer, full laminar pattern for an optimum aerodynamic performance. Company officials said that this creates a near perfect environment-separating air seal across any open doorway while providing auxiliary heat, as needed.
Powerhouse Dynamics has expanded the remote equipment control functionality of its enterprise energy and asset management system. In addition, the company reported that the system has been renamed SiteSage™, replacing the eMonitor™ name under which it has been known. SiteSage is designed for multi-site operators of small commercial facilities, such as restaurant, convenience store, and specialty retail chains. According to the company, the new SiteSage Controller has the ability to control equipment and has been extended beyond HVAC to any equipment including lighting.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
