LG rotary compressor performance sheet
I'm looking for compressor performance sheets, or selection software, for the LG rotary compressors. Refrigerant R-22.
I've found the standard specification documents, but no information is provided on Te,sat , Tc,sat, COP, power usage etc.
The COP versus Te,sat & Tc,sat information is what I'm really after - for training purposes.

Re: LG rotary compressor performance sheet
Could you use data of some other manufacturer for training purposes, or it must be LG?

Re: LG rotary compressor performance sheet
Thanks Nike.
The compressor is in a Galanz outdoor unit. The compressor name has been removed, but, it appears to be a direct copy of the LG rotary compressor.
I was hoping to be able to use the compressor performance data sheet to confirm a field 'cheap & cheerful' COP,r calculation technique & then train the staff accordingly.
Are there alternative rotary compressors where data sheets can be used? This should be fine.Engineering Specialist - Cuprobraze, Nocolok, CD Technology

Re: LG rotary compressor performance sheet
Any ideas on typical compressor isentropic efficiencies for these rotary compressors, compared to a scroll compressor?

Re: LG rotary compressor performance sheet
Scrolls, I must say I have always had decent data to work with, I have tended to use full manufactures info.

^ Agreed. The major scroll compressors have excellent support in the technical support information.
This LG rotary seems to have zip, as far as I've been able to unearth, so far.Engineering Specialist - Cuprobraze, Nocolok, CD Technology

Re: LG rotary compressor performance sheet
I did not found any LG data but at last page of this PDF is nice diagram for one Hitachi rotary.
It appears that his isentropic efficiency is around 0.65 (by Coolpack).Last edited by nike123; 20-10-2009 at 07:43 AM.
