    ASHRE table help needed forgotten.



    I can not remember (it has been 25 years since I apprenticed in my teens, and I have since changed careers, so forgive me)

    With the Ashre tables on a compressors specifications for a compressor, how do they test the system to determine the BTU rating.

    What I mean is the following,

    If I use the -25c on the (ASHARE LBP) that is the lowest temp on the chart, and then use a capillary tube for the -25'C temp, will this give me all the BTUs/ temp range on the table.

    Or to say it another way will it if capped for -25'C Will the system reject everything from 15'c @5459 BTU's on the table down through the -25'C @559 BTU's

    OR

    Does each temp/BTU rating on the table have its own cap tube diameter/ length?

    1. Which scenario is correct the first or the second?

    Thanks for your help every one
