COMBUSTION EFFICIENCY PANEL
Delphi combustion efficiency panel is a single, pre-wired combustion panel that integrates flame safeguard control, fuel air ratio control, O2 trim, variable-frequency drive (VFD) and proportional integral derivative (PID) controls. Delphi improves burner efficiency, enhances safety, and reduces installation costs. The accurate, fast-responding O2 sensor continuously corrects and optimizes the fuel-air ratio. It also compensates for variable combustion air, trims the damper - or the variable-frequency drive - and the boiler to the most efficient and effective fuel-air ratio. The panel has the potential to contribute points toward LEED certification in two of the three LEED environmental categories; Energy and Atmosphere, and Indoor Environmental Quality. www.customer.honeywell.com
The Comfort System™ VAV diffuser from Jackson Systems can help a building earn LEED points.
The Comfort System™ VAV diffuser from Jackson Systems
is used to vary the supply air volume from the company’s newly revised Z-2000-T™ wall-mounted thermostat. The diffuser is designed to maintain draft free discharge air along the ceiling providing a sustained discharge velocity throughout the volume range. Each of the VAV diffuser and Z-2000-T assembly provides individual set points for both heating and cooling for individual areas throughout a building. Using VAV diffuser and Z-2000-T assembly can help a building earn LEED points for new construction, commercial interiors, schools, existing buildings, and operations and maintenance in LEED building rating system areas such as IEQ Credit 6.2: Controllability of Systems-Thermal Comfort, IEQ Credit 7.1: Thermal Comfort - Design, EA Credit 5: Measurement and Verification. www.jacksonsystems.com

Heat Pump with Virtual Moveable End Cap (VME) eliminates the need for a separate hydronic heating and cooling system; the same array of modular machines can be used to do both jobs, says the company. The key to VME is the control system that will automatically open and close isolation valves as required to match the simultaneous heating and cooling output of the modular array to just what a building load requires. By eliminating a dedicated boiler, the required equipment installation footprint is dramatically smaller and positions one to look at LEED points for Emission Reduction Reporting. The VME systems are available from 10 tons to 1,000 tons and can provide up to a 75 percent reduction in CO2 emissions. www.multistack.com
The McQuay International Pathfinder air-cooled screw chiller helps owners qualify for LEED® Green Building Rating System certification through optimizing system efficiency and enhanced refrigerant management.
CHILLER REFRIGERANT PURGER
(oil-acid-moisture purger) regains chiller capacity. It quickly cleans the chiller’s refrigerant charge to only a trace level of oil and quickly restores a chiller to peak operating efficiency. The purger substantially reduces energy consumption, saving the owner thousands of dollars in operating cost, says the company. According to the manufacturer, the product is applicable (and some installs have received) LEED points, Green Buildings points, and utility rebates, and energy managers are taking advantage of energy saving tax credits for HVACR energy-saving improvements. www.redicontrols.com
