14 Lab Testing Update

15 Test Summary Lab: Cascade Engineering Services, Redmond Washington Test Date: Winter 2011 Test Protocol:  Compressor Performance Mapping  DOE Standard Rating Tests  Operating Mode Characterizations  Fan and Airflow Measurements  Draw Patterns

16 Test Unit Manufacturer: AirGenerate Model: ATI66 Features:  66 gallon nominal (64 measured)  Tank Material: Stainless Steel  Refrigerant – 410A  Electric Element – 4kW  Compressor Size – 7700 BTU/Hr  Exhaust ducting  Reverse cycle defrost  Supports simultaneous resistance element and heat pump operation

17 COP – (30F / 80%RH)

18 COP – Auto Mode (40F / 95%RH)

19 Draw Profile – Varied Ambient DP4-67DP4-40 Ambient 67.5F, 50% RH 40F, 95% RH T inlet 58F45F T setpoint 135F EF Draw profile targets 30 gallons Based on small draw pattern from Gas Technology Institute (GTI) * Smaller draw profile can be performed quickly * Kalensky, D. and Scott, S. GRI-06/0014, GTI Combo System Field Test Final Report, Gas Research Institute, December 2006.

20 COP – Compressor Only – (50F / 58%RH)

21 COP – (50F / 58%RH) / w(50F / 95%RH)

22 Fan Characterization  Fan maintains significant flow over range of static pressures  All COP mapping condutcted under 0.25" static pressure  except low-flow 40F test at 0.75"

23 COP Test Summary Findings TestAve COP for Tank T: 60F->120F Comments COP COP COP defrost cycles COP-50w defrost cycle. Higher enthalpy than COP-50 results in higher COP COP-40_auto1.71 COP decreased by use of upper element in auto mode to heat top 1/3 of tank to set point. Defrost cycles. COP-40_auto As in COP-40 except static pressure set to 0.75”. COP not lower partially because fan power drops & heat transfer not compromised. COP Many defrost cycles

31 Lunch Time Northern Climate Energy Factor

32 Why a Northern Climate Energy Factor? Current DOE EF calculated at 67 degrees F Climate sensitive EF better predictor of savings and customer satisfaction Helps differentiate products

33 Calculation Method Calculation is based on the HSPF procedure which creates a single value from a weighted distribution of temperature bins.  Definitions:  EF 67 is the energy factor from the standard DOE 24-hr test.  EF 40 is the energy factor from the Northern Climate simulated use test.  EF R is the energy factor for the HPWH operating in resistance heat only mode.  Uses tested value if reported, or assigned as  Applies whenever compressor is not operational

34 Calculation Method: T bin Table jT db(F)Hoursf f 1 > % % % % % % % % % % % % % % 8 < % % WA ExampleMT Example Hoursf % % % % % % % % GA Example

35 Calculation Method (continued) The Northern Climate Energy Factor is calculated as:  (1) Where j is the bin #, f j is the fraction of hrs for that bin, and: EF j = (T j -40)*m EF + EF 40 (2) Where m EF is the slope connecting the two energy factors:  m EF = (EF 67 -EF 40 ) / (67-40)(3)

36 Example Calculations  Using NW climate example T bin weightings. Tdb (F) Ex AEx BEx CEx D EF MT : EF WA : EF GA : Ex AEx BEx C Ex D EF EF Low T Limit50°F none Peak winter load impact?

37 Future Needs for EF NC Development  Representative operating temperature bins  Climates and install locations  Set # of varied ambient conditions for EF draw patterns  Currently using 2. More is better but takes time.  Create a representative draw pattern to use in the simulated use test  Ideal pattern is completed in 8-12 hours (or less)  Target gallons

39 Imagine… Heat Pump Water Heaters could change the landscape of energy efficiency in the Pacific Northwest. Imagine how Heat Pump Water Heaters could change the landscape of energy efficiency.

40 Consider… Every home should have a Heat Pump Water Heater. Consider what we can do to ensure every home has a Heat Pump Water Heater.

41 Think… Heat Pump Water Heaters could be the key to achieving our regional energy efficiency goals. Think about how we might navigate the current market conditions to achieve our regional energy efficiency goals.

42 Imagine. Consider. Think. What are 5 key components to successfully implementing Heat Pump Water Heaters in the Pacific Northwest?

43 Imagine. Consider. Think.

44 Imagine… The Pacific Northwest is a leader in energy efficiency solutions. Imagine the Pacific Northwest as a leader in finding the most effective path to Heat Pump Water Heaters being installed in every home.

45 Consider… It’s going to take a collaborative effort to get Heat Pump Water Heaters into every home. Consider what connections, collaborations, and resources you have available to make this vision a reality.

46 Think… Working together could lead to desired outcomes quicker and more effectively. Think about the possibilities of working together to make Heat Pump Water Heaters a mass market solution for energy efficiency.
