    Product Load Calculation



    When calculating a refrigeration heat load,is the product load final temp same with the required room temp?
    Ex:Blast Freezer Room
    Required Temp:-40C
    Product Load :Meat Product
    Do we compute the
    specific heat of product load base on the required temp?
    Any feedback from our refrigeration expert.

    Re: product load calculation

    If you were working out the product load for a blast freezer and you are taking the meat from chilled/warm to frozen you would need to factor in the specific heat load of the product for latent load. The amount of heat removal to change the state of a product is far higher than that for reducing its' temperature when it is above or below its' freezing point.

    if you are in doubt consult some one who knows!

    Re: product load calculation

    you have to calculate;

    *on what temperature you bring the goods in.
    *howmany kilo or ton you bring in.
    *howlong are the doors open,and do they have plastic flaps .
    *do you bring the goods in manual or whit forklift.
    *howmany men/women are inside ore moving in and out.
    * wat is the outdoortemperatuur wile you bring the goods in.
    *is the freezer situated indoors or outdoors.
    *is there floor isolation or not.
    * how thick are the walls.
    *wat kind of lights are used. and howmany.
    then you can start whit some calculations,and maby there gone be some more questions on how big do i calculate the evaporator(s),and wat is the best place to mount.

    good luck,

    O forgot,
    if you take the final room temp for the final goods temp,your wrong.
    there always have to be a higher room temp needed to end up whit final goods temp.
