## *Summary of Carrier and Nordyne waivers 

## *Briefing on the testing NIST has performed on multi-function equipment 

## *Possible discussion items:

- Is there a need to develop a simple wayto combine the ratings for differentfunctions of combined products in such a way that they can be compared to single function products? .

- Identify all types ofmulti-function residential HVAC appliances now in the marketplace and how the energy efficiency ofeach appliance type is currently being described.

- Status and scope ofASHRAE standard 137 (Methods ofTesting for Efficiency ofSpaceconditioninglWater-heating Appliances that Include a DesuperheaterWater-heater)

- Status and scope ofARI standard (AirConditioning and Heat Pump Equipment Incorporating Potable Water-heating Devices)

- DOE's plans regarding ASHRAE standard 124 (Method ofTesting for Rating Combination Space-heating and Water-heating Appliances)

- Use ofseparate descriptors for each energy source used by an appliance

- Would consumers have adequate means to calculate annual operating costs? 12:00 Lunch1:00 Finish discussion on Multi-function appliances

1:30 Session 3: Multi-fuel Heat Pumps * Briefing on ANSI standard Z.21.40.4 and its appendix * Possible discussion items: - Identify all types of multi-fuel heat pumps (engine-driven, sorption, burner-assisted, desiccant) and identify test methods, ideas, and alterative methods of reporting performance. - Status and scope of revisions to ASHRAE Standard 40 (Method of Test for Heat Operated and Engine-Driven Unitary Air Conditioning Equipment) - Status and scope of ANSI Standard Z21.40.4 (Performance Testing and Rating of Gas-Fired, Air-Conditioning and Heat Pumping Appliances) and its Appendix A ( Methods ofDetermining Efficiency Ratings and Operating Costs of Gas-Fired Heat Pumps for SpaceConditioning Performance) - Statutory and marketplace limitations - Use of separate descriptors for each energy source used by an appliance - Would consumers have adequate means to calculate the annual operating costs of these appliances? 3:00 Session 4: International Test Procedures * Brief background segment on ARI's request for DOE to consider international standards * Possible discussion items: - Are there international test procedures for all products? Are the international test procedures adequate? Can they be used to obtain the information DOE needs? - Is there an advantage to the industry to use international test procedures? 4:00 Wrap-up Discussion 1:00 Finish discussion on Multi-function appliances 1:30 Session 3: Multi-fuel Heat Pumps
