As per our conversation.
 
I checked a stand alone refrigerator  and a stand alone freezer at Sears.
They are both Kenmore 16 cu ft.
The freezer  model 253.4473310 uses 134A refrigerant holds 50oz. or 143 
grams
The refrigerator  model 253.44723100 uses 134A refrigerant holds 4.5oz or 
128 grams.
I asked the Sears Tech why the higher charge amount in the freezer, and 
was told to make sure it gets to  0  degrees and stays there.( I cannot 
understand that answer).
 
Let me know if this is good enough.  I can get a picture of the name 
plates and attach it .
 
With 134A my normal charge with HCR188C will be at 25% for both 
refrigerator and freezer.
 
This would be a drop in.

Richard,
A test would satisfy us. However, that may not be necessary. Please
find if there is information demonstrating that freezers do not have a
significantly different charge size, if they use the same refrigerant
and have the same volume to be cooled. Better still, provide this as a
ratio of charge size for a freezer to a refrigerator.

Re: Fw: freezer 

Margaret

Are you saying that I have to run another test at Intertek for a stand
alone freezer like the refrigerator to justify the charge size of
HCR188C.If so then I need to purchase a stand alone freezer and run the
same test as the refrigerator . Get the charge size documented with
performance running. Is this what the EPA is looking for.

Richard,
As in my November 1, 2007 email below, I was expecting a clearer and
more complete justification for the freezer charge size. Darren's brief
explanation was not adequate.

Darren just wants to confirm that you accept the charge rate on the
freezer.
His risk assessment on the freezer has the charge rate that I supplied.
He also wanted to clarify the window ac. See attached.

Re: freezer(1)

Richard,
Darren's addendum states that the freezer had the same "charge and
performance rates" as for the refrigerator. Please clarify what is
meant
by performance rates--what measure of performance, from what source,
and
in what units of measure? Since a freezer would need to go to a lower
temperature than a refrigerator, it is somewhat surprising that they
would have the same performance and the same charge.

Please identify the refrigerant in both the refrigerator and in the
freezer in your justification.
