    qwestion about entalphy in compressors




    Hello.
    Along the C-D line liquid subcools and gives out heat, and along the F-G line SH takes place and gas continue to take in heat. It is not clear to me what entalphy is inside the compressor (G-A line). Gas also takes in so and so kJ/kkg of heat - according to p-h charts?!

    Edit . My picture did not come out. I meant the arc line on the right of a p-h diagram for a refrigerant compression.

    Draw the lines for the compression (hc - hd) vertically down to the specific enthalpy on the base line.
    hd - hc = specific enthalpy

    I'll try to scan an example in tomorrow (from Dossat)
    I'm back on the Pale

    "Heat of compression" as result of gas molecules friction during compression, said to be "absorbed" , but, absorbed from where ?
