19 BOC Tech Talk Economizers Free Cooling

20 Small Packaged HVAC Equipment Packaged Rooftop Units (RTU) Gas Packs Heat Pumps All Electric Air Conditioning Units Sized in tons of cooling capacity and btuh of heating capacity. They condition a large fraction of all commercial building spaces. Mostly constant volume - also includes VAV and VVT 2012

21 Market Characterization 34% of commercial buildings have packaged HVAC units 150, ,000 units in the field (522M sf of space) New sales of approx. 7,000-9,000 units Approximately 800 contractors in light commercial HVAC 2012 Data for Pacific Northwest region Published in Light Commercial HVAC Market Assessment - Report No B Northwest Energy Efficiency Alliance, 2005

24 How are RTUs rated? Seasonal Energy Efficiency Ratio (SEER) The higher the SEER rating of an RTU, the more energy efficient it is. The SEER rating is the Btu of cooling output during a typical cooling-season divided by the total electric energy input in watt-hours (W h) during the same period. SEER = BTU W h Minimum federal requirement = 13 SEER 2012

28 Building Cooling with Outdoor Air Outdoor air conditions are often optimal to provide building cooling as: Full OSA cooling Pre-cooling benefit for mixed air OSA Damper Operation Heating Mode Damper set to minimum position First Stage of Cooling with Economizer Damper set to full open position Second Stage of Cooling without Economizer Damper set to minimum position Minimum Damper Position 10-20% OSA Maximum Damper Position 70% OSA or greater 2012

29 ASHRAE requirement Economizer required >54,000 BTUh Must Have integrated economizer (simultaneous economizer and compressor operation) Zone 4A Dry-bulb economizer not allowed 5A 4A
