Hermetic fridge compressor - operating envelope.

[desA]

I am looking for compressor operating envelope information for typical fractional horsepower, hermetic fridge-type, high-back-pressure unit.

If anyone has links, or information which I can use to cross-reference Japanese equivalent compressors, I would be most grateful.

Many thanks,

Its called Google, it should be in your toolbar at the top left of your home page.....

Look for Danfoss compressors, Embraco compressors, Tecumseh compressors, Aspera compressors and Necchi compressors.

These are the leading manufacturers of small compressors.

There are other small manufacturers in the far east but they are not as good.

I fully understand how Google works.

Perhaps I should have explained myself better.

The Danfoss program RS+3 is quite useful in giving the envelope data I'm looking for. The Japanese compressor I have in my test lab (Hitachi) has very little accompanying information. Nothing is said about operating limits, or envelope - only LBP & HBP compressor.

I was hoping to find out just how far a typical HBP compressor can operate. Danfoss have a range of heat-pump compressors with an extended operating envelope. This may better suit where I'm aiming.
