Buckdate: news and updates for specifying engineers

Vincent MaccarroneTo Specifying Engineers:

Greenheck is pleased to announce the release of its free Toolbox App for IPHONE, IPAD, and Android devices. The new application contains a Fan Law Calculator and a Ductulator to help engineers and contractors make quick calculations.

Fan Law ScreenshotFan Law Calculator
Users input the existing specifications for RPM, CFM, static pressure, and horsepower, and then input any one measurement you would like to change and the remaining values will automatically calculate using standard fan laws.

The Ductulator
Allows users to easily size HVAC duct by entering duct shape, rounded dimension, air temperature, elevation and roughness. Sizing can then be determined by airflow or dimensions. Select velocity or friction factor, input the volume, velocity and aspect ratio and the results are automatically calculated and displayed.

You can download the toolbox app from the Apple Store or Android Marketplace.

Improve ERV Efficiencies with Ebtron Probes

Mike Leydon

HE1 ERV ProbeDo you want to get the most out of your ERV? In order to do this you must know what is happening within the equipment.

By utilizing the Ebtron Hybrid ERV model HTA104-E you can help achieve higher ERV efficiency, greater economy of operation and improved indoor air quality.

Applications

  • Control space pressure and outside air delivery to achieve compliance with the ventilation rate procedure of ASHRAE 62.1-2007.

  • Contribute towards acquisition of LEED Credits:

    EA - Energy and Atmosphere - Minimum Energy Performance - Optimize Energy Performance - Measurement and Verification

    IEQ - Indoor Environmental Quality - Outdoor air delivery monitoring - Increased Ventilation

  • Precise airflow and temperature measurement for ERV enthalpy desiccant wheel systems from 0 through 2,000 FPM for improved efficiency, control and energy conservation.

The Ebtron Hybrid ERV is the perfect solution for small to medium-sized ERV's. The HE1 probes represent a competitively priced and technologically superior alternative to legacy pressure-based instruments which are inherently less accurate at the low face velocities present in modern ERV systems.

Improve Sound and Efficiency with Greenheck Housed Plenum Arrays

Bob Sirois

HPAThe Greenheck Housed Plenum Array model HPA has been specifically designed for air handling applications. The HPA is a direct drive plenum fan mounted inside a sound attenuating housing. This modular design allows for easy side-by-side and stacked fan arrays to handle an extremely wide range of CFM’s and static pressures.

As always, Greenheck brings to market a product that is AMCA licensed for both air and sound. The fans are high efficiency, 12-bladed aluminum airfoil wheels, mounted on a structural frame on neoprene isolators. Greenheck brings flexibility to the market with three housing sizes and options like:

  • VFD compatible motors
  • Partial width wheels
  • Blank-off or inlet dampers
  • Sure-Aire flow measurement
  • Shaft grounding rings

Consider the HPA on your next project involving packaged air handlers, built-up air handlers, custom air handlers, retrofit projects or general supply and return air systems.

Price Introduces Floor Mounted Active Beams for Use in Classrooms

Steve Nemec

EAS Central Utility Plant
Model ACBC - Floor Mounted Active Beam
The Price model ACBC is an exposed, perimeter unit suitable for office spaces, schools, hotels, and retrofit of existing induction systems or any application where occupant comfort demands are high.

Ventilation air from a DOAS (Dedicated Outdoor Air System) is mixed with induced room air and discharged at relatively low velocities out of the lower face section. The ACBC is designed to function in heating or cooling mode with a 4 pipe coil option and primary air supplied. It can also be operate in the passive heating mode with primary air turned off during night or unoccupied modes.

The ACBC can be used as a standalone or can be connected in series by interlocking plenums to create a continuous look. The ACBC and most Price beams have an optional drain pan. Price is the North American leader in beam technology offering the largest selection in the industry.
