    How many times must one fix something before it is fixed?

    Or, as one of my AC instructors back in 1997, Mr. Abbott would say, “That's a good guess” or maybe my personal favorite “Body shop is right down the hall!”

    I think both are both - well; in refrigeration anyway.

    The conventional view serves to protect us from the painful job of thinking.

    The "Ton" is based on 2,000# of 32° ice transforming into 2,000# of 32° water.
    In other words 2,000# x the latent heat of Fusion (144btu's/#) is 288,000btu's.
    So in that sense, a "ton" WAS originally based on latent heat.

    NOTE that 288,000 is for a day/24 hrs.
    This was divided by 24 (as in hours) hence 12,000 btu's/ton (at least for an A/C ton).

    How many BTUs in a Ton was determined that way. But it still doesn't make Ton latent heat , and BTU sensible heat.
