Compression ratio

Dear Friends,

I have a question. Do you have any document that explains refrigeration compressor compression ratio at air-conditioning system and refrigeration systems ?

Thanks.

Compression ratio = Discharge pressure / Suction pressure. (Absolute pressures should be used).

The smaller the ratio is, the more efficient the pumping is.

If the ratio is high, less refrigerant mass is pumped over a given time especially in piston compressors, therefore more energy is consumed over time by the compressor motor or drive to achieve the same refrigerating effect as opposed to a low compression ratio.

Lower compression ratio = more pumping.
Higher compression ratio = less pumping.

No documents but hope this helps.

Hi, A.Mortezania :)

it is archived a lot of answered questions here on RE forums ...

but you need to do searching by yourself ...

sometimes much better if you want to learn something .... believe me;)

RE archive is like ... Treasure chest ... https://www.amazon.com/Century-Novel.../dp/B002POEQEK
