    Tonnage to KW



    This may seem a dumb question but is there as mathematical equation to convert tons of cooling in to kw's i've googled but only found converters and would like to be able to work this out for myself
    eg if i had a small chiller unit rated at 95 tonnes what would that equate to in KW'S
    thanks
    James

    3.5 KW=1 ton refrigeration=12K BTU

    95X3.5=332.5KW

    Not BTU or KBTU but rather BTU/h or KBTU/h because it's a rate of energy (power).

    Yeah Sandro, Isn't 1 british thermal unit raising 1 pound of water by 1 degree F/ hr? Having to dig into soggy memory now.

    God I love this site.......Btu's... I never knew thats what it implied. I knew it was British Thermal Unit....but not the "one pound of water raised by 1 degree F over 1 hour" its almost orgasmic the learning still going on...well ok I am getting a bit carried away.

    Maybe for someone who know's the answer, We only know what we've been taught/self taught when we reach a problem surley it's better to find a solution than sit on it and not know the answer, I'm sure the first time you had to convert something ie pressures/temperatures you got this formula from somewhere or maybe you were born knowing I know i wasn't.

    Re: Tonnage to KW

    one ton of air conditioning = 12000 btu/hour

    3,412 btu/hour = 1 kW

    therefore kW = 12000/3413 tons
    = 3.517 tons

    or kW = tons x btuh/ton x kW/btuh
    note that the units cancel, leaving kW

    95 tons x 3.517 = 334 kW as noted by Chemi-Cool back in June

    Hi James.
    No what ever intended, I trained back in the 60's with transition from imperial to SI metric. I bought a book as a reference guide. This is when slide rules were common, before calculators let alone computers.
    Everything now is available on the net.
