RE: Hydrocarbons and energy efficiency

Amy

Attached is a study that examines the energy efficiency effect of HC as 

compared to HFCs and finds an energy penalty.

David,

I think you’re right that the initial paper I sent you was perhaps too 

theoretical. Attached is a paper more to the point.

I hope we’re able to discuss this in DC next week.

Best,

Amy

I will take a look at this, however, at first glance I don’t see how this 

is conclusive evidence that HCs are more efficient than HFCs for 

Refrigerators, etc... This report would appear to examine the issue from a 

more generic standpoint, and doesn’t look at these substances as they are 

used in actual products (R/Fs, etc...), which is how a proper evaluation 

would have to be done. 

Best regards,

Dave

Subject: Hydrocarbons and energy efficiency

Dear David and Dave,

Yesterday, in a phone call with David Calabrese of AHAM, he mentioned 

that 

there is an "energy penalty" for hydrocarbon refrigerators. I'm 

forwarding some information which clearly disputes this. If any of you 

have information that contradicts this, I would very much like to review 

it.

I've attached a paper out of the School of Mechanical and Manufacturing 

Engineering at the University of South Wales, entitled "Why Hydrocarbons 

Save Energy".

Also, please reference the website below: 

http://www.energy-plus.org/english/news

It outlines the most efficient refrigerators on the European market in 

2004 (those labeled A+ and A++). 

There were 85 A++ models (all hydrocarbon) and 769 of the 781 A+ models 

were also hydrocarbon.

In addition, my European colleagues have anecdotal reports from the 

largest manufacturers and retailers who indicate that the introduction of 

hydrocarbons have given their refrigeration fleets an extra boost in 

energy efficiency. 

I hope we're able to review this and any other concerns next week in DC.

Best,

Amy

Subject: HFC-245fa vs HC blowing agents for refrigerators

Dave;
Please find the most recent research comparing HFC and HC foam blowing 

agents attached.

In short;

- annual refrigerator energy use is the largest contributor to 

the CO2 emissions total

- in identical refrigerators, HFC foam uses 12% less energy than 

HC foam

- HC has 3% greater outgassing from the foam over time

- With outgassing, HFC foam uses 15% less energy than HC over 

time

- US factory safety regulations for use of flammable gases are 

significantly more stringent in the US 

- Europe has placed a high value on direct greenhouse gas 

emissions 

- The limited analysis total CO2 emissions shows the amount of 

HFC advantage varies based on details of de-commissioning of the foam 

Hope this is helpful
