A qustion about compressors on domestic refrigeration.
Hi.
Can someone tell me how you can identify on a compressor the technical info on it i.e. H/P etc.
Just that I can never find this info on the label usually but maybe I am mistaken.
Sorry if it is a daft question but I am just curious.
Thanks in advance.
Bobby.

Model number on compressor will enable you to ascertain size and suction pressure range.
Re: A qustion about compressors on domestic refrigeration.
Usually check the model number from the label with the manufacturers information is the safest way.
Re: A qustion about compressors on domestic refrigeration.
to be honest there is no rule of thumb, different manufactures use different methods. Probably the easiest thing to so is go to an HRP or Climate centre and pick up a catalogue. These then show the most common makes and what the letters stand for. If however you want details on a certain compressor, post the details on here and we can help. Usually the big numbers on the top are what we need for instance :-
Danfoss TL5 or
L'unite CAJ2464z or
Aspera ####### etc
Hope this make sense

Hi all.
Thanks for the replies.
As a for example, a Danfoss compressor which has a number on it of SC15F. How & what can I tell from that?
Cheers.

Aha. I think I have an answer to my question above. The 15 signifies 15cc displacement. Am I right? Do the letters identify the HP in some way?

Hi have a look at this

Re: A qustion about compressors on domestic refrigeration.
I've tried to get diffrent cheaper alternative compressors for domestics. Getting details of the old compressor and using google to find the h/p or watts. but u can get two compressor of same horsepower but they give diffrent performances. Over time i've found reliable,cheap compressor that are specific for each fridge

Compressors are pumps and if they have same displacement and same area of usage (motor power) than they will perform same.
Those two are key criteria for finding suitable replacement compressor.
HP doesnt mean anything without conditions for which are HP given. If conditions, are different you are comparing apples and pears.

No, and HP is misleading! Don't care for HP. You only need exact same displacement (if you don't want capillary adjustment) and pretty much same motor power. Motor power for same displacemant could be diferent acording to usage (low evaporation temperatures, medium ET, high ET, AC ET). Your replacement compressor of same displacemant need to have motor for same usage area.

So HP is irrelevant. It is the displacement in cc & power in wattage that is important, yes?

Yes, power of motor and cc and type of motor starting (LST for capilary systems and HST for expansion valve)
