### Re: Samsung Petition for Waiver and Application for Interim Waiver, DVM 

### Air Conditioner and Heat Pumps

Dear Assistant Secretary Kelly:

Sam sung Electronics America, on behalf of Samsung Electronics Co. (Samsung), respectfully submits this petition for interim waiver and application for waiver to allow Samsung to fairly evaluate its new line of DVM air conditioners and heat pumps.

Under 10 CFR 431.40 I (a)( I), any interested person to submit a petition to waive for a particular basic model any requirement for commercial equipments, upon the grounds that either the basic model contains one or more design characteristics which prevent testing of the basic model according to the prescribed test procedures, or the prescribed test procedures may evaluate the basic model in a manner so unrepresentative of its true energy consumption characteristics as to provide materially inaccurate comparative data.

Sam sung originally submitted a petition for waiver and application for interim waiver for its DVM system on October 7 , 2003, seeking relief from 10 CFR 430 based on the fact that the multitude of combinations of outdoor and indoor units makes it highly impractical for Samsung to test every single combination. For this reason, DOE granted Samsung the Interim Waiver on February 8, 2005.

On December 8, 2006, the Department of Energy (DOE) published a final rule adopting ARI Standard 210/240-2003 for commercial package air conditioning and heating equipment with capacities < 65,000 Btu/h and 340/360-2004 for commercial package air conditioner and heating equipment with capacities 2: 65,000 Btu/h and < 240,000 Btu/h. However, under these new test procedures, Samsung would still be required to test every single combination of its commercial DVM outdoor and indoor units. Based on DOE's recognition that (I) there is a problem of being physically unable to test most of the complete systems in a laboratory; (2) there are difficulties associated with the regulatory requirement to test the highest-sales-volume combination; and (3) there is the lack of a method for predicting the performance of untested combinations, DOEgranted Samsung the waiver from having to test every single combination of its DVM system in 72 FR 71387 , on December 17,2007.

Since then, Samsung has further improved its DVM system, establishing new models not covered in the waiver published in 72 FR 71387. Even though model numbers changed , the difficulty with testing the multitude of combination of Samsung's DVM models remains ; therefore , Samsung is seeking DOE ' s granting of waiver and interim waiver for the following Samsung DVM models:

Each outdoor unit may be combined with up to ten different indoor units and each indoor unit may be independently turned on , off , standby , etc. depending on user-desired settings

. With up to 33 different indoor units for the consumer to choose from and combined , and as evident in the chart above , there are thousands of different combinations, creating an extremel y burdensome task for Samsung or any testing laboratory to evaluate all possible combination. Being respon s ible to te s t every conceivable combination would place an unfair burden upon Samsun g, while offering no added value for purpose of energy testing. Samsung 's new DVM system is very similar to Samsung ' s old DVM system , which DO E had granted a waiver for in 72 FR 71387

. Until a final test procedure addressing commercial central air conditioners and heat pumps , similar to Samsung ' s DVM systems , is prescribed , Sam s un g believes that the interim waiver as granted by the Department in 70 FR 9629 and waiver as granted b y the Department in 72 FR 71387 , be granted for Samsung ' s new DVM sys tem in order for Sam s un g to f easibl y evaluate its new line of DVM central air conditioners and heat pump s.
